1. New Features.

This section lists the features added from the previous Open AT^® Firmware 7.3a.

Pre-programmed flash for WMP : software package in WPK format allows to create a flash image through DWLWin tool (4.1.6.13 or further). This image can be used to pre-program flash to ease the Wireless Microprocessor production.

Auto quad-band: In auto quad-band mode, the Wireless CPU^® automatically chooses between the 900/1800 MHz bi-band or the 850/1900 MHz bi-band according to the radio environment. This feature is only available in beta stage. For more information, refer to AT+WMBS in AT commands Interface Guide.

Silent Sim Toolkit: In silent Sim Toolkit mode, the Wireless CPU^® can receive and execute Sim Toolkit commands coming from the network without disturbing the customer application by several indications. For more information, refer to AT+STSF in AT commands Interface Guide.

1K-Xmodem download through USB and UART2: The new bootloader is supporting the 1K-Xmodem protocol over USB and all UARTs to download a new binary in DWL format (either bootloader, Open AT^® Firmware or Open AT^® applications). It also means that the M2M Studio is able to download over USB and all UARTs any binary in DWL format. This feature is only available in beta stage. For more information, refer to AT+WDWL in AT commands Interface Guide.

Wireless CPU ^®default serial port is UART1 and USB: UART1 and USB serial ports are activated by default for all Wireless CPU^® produced with Open AT^® Firmware 7.4. This feature is only available in beta stage.

3. Known restrictions

Id	Description (What / When)	Impacted Domain	Impacted Sub Domain
Id	Description (What / When)	Impacted Domain
41086	When AT commands sequence (combination of multiple and single commands) is sent quickly from external application, the response is not received in proper order.	AT	OTHER
41916	When the application use the AT+CUSD command to send USSD strings to the network by using the GSM 7 bit default alphabet table (defined in GSM 23.38 specs) and when the USSD string contains some extended characters like [,], {,}, , ¦, ~ and ^, that are not defined into the GSM 7 bit alphabet table, the Wireless CPU^® replaces each extended characters by 0x20.	AT	OTHER
41921	When +WDIAGI indications are activated (AT+WDIAG command), some unsolicited responses are returned by the Wireless CPU^® during an outgoing data call between CONNECT and NO CARRIER responses. These indications should not be returned.	AT	OTHER
41927	A command is sent and an unsolicited response (+CREG: 2) is returned before the OK response. Normally the unsolicited response has to be returned after.	AT	OTHER
41929	Autobauding is not able to resynchronize with the modem after a NO CARRIER response is received after releasing an active GSM data call. This is only met if customer changes speeds between establishing and releasing the data call.	AT	OTHER
41934	Interrogating the Call Forwarding state on a specific class (voice (AT+CCWA=1,2,1 )or data (AT+CCWA=1,2,2) or fax (AT+CCWA=1,2,4)) returns +CME ERROR: 30. The Call Forwarding state of the required class should be returned by the Wireless CPU^®. Interrogating the Call Forwarding state of all classes (AT+CCWA=1,2,7) is working.	AT	OTHER
41938	When an outgoing call is in progress (ATD command) and not yet established, +WAC command resets the ATI automaton. In this case, all AT commands sent after +WAC command and before OK response to Dial command returns the corresponding response instead of +CME ERROR: 515. The Wireless CPU^® should return +CME ERROR: 515.	AT	OTHER
41947	Impossible to modify PIN1 value before receiving +WIND: 4 indication. It should be possible to modify the PIN 1 code between the moment when this code is entered (and validated) and +WIND: 4 indication.	AT	OTHER
41948	Incoming Data Call gets connected even when the IPR and the DTE-DCE data rate are different.	AT	OTHER
41950	If the SIM contains sufficient EXT files, AT+CPBW=? can return a max phone length equal to 80 digits. But if an entry with a phone number containing between 61 and 80 digits is tried to be written, +CME ERROR: 20 is returned by the Wireless CPU^®. The entry should be written (if SIM contains sufficient EXT files).	AT	OTHER
41952	In SLOW CONNECT mode (AT+WGPRS=5,1) for PALM OS, when a GPRS session is launched, CONNECT response is sent as response instead of data response.	AT	OTHER
41954	When setting the speed of serial link to a speed lower than 9600, this speed is displayed into the CONNECT response instead of the data call connection rate.	AT	OTHER
41957	When AT+CGDATA=<cid> is entered, GPRS session is not activated and then "NO CARRIER" returned.	AT	OTHER
41968	When MCC Lock feature is activated and an invalid SIM is inserted, the "SIM NOT ALLOWED FOR THIS MODULE" message is not returned by the Wireless CPU^® through all opened ports (physical or virtual). If only UART 1 is opened, the message is always returned through UART 1 but if several ports are opened, the message is not sent to all ports. This message should be returned by the Wireless CPU^® through all opened ports.	AT	OTHER
41969	When the MCC lock feature is activated, the SIM removal is not detected in the following procedure: 1) Insert an invalid SIM card (SIM NOT ALLOWED FOR THIS MODULE is returned by the Wireless CPU^®. 2) Remove the invalid SIM and insert a valid SIM 3) Enter the CHV1 code. 4) Remove the SIM. The SIM removal is not detected, +WIND: 0 is not returned by the Wireless CPU^®. The SIM removal should be immediately detected and +WIND: 0 indication should be returned by the Wireless CPU^®.	AT	OTHER
44395	When the AT command parser is locked (see AT+WCMF command), if an Open AT^® application is downloaded and executed on the Wireless CPU^®, it is possible to issue AT commands. Ideally, since the AT command parser is locked, AT commands should not be allowed, even when Open AT^® application is under execution.	AT	OTHER
45350	When the WIRELESS CPU^® is configured with AT+WBHV=0 (to send the terminal response of an outgoing call when the audio path is establish), the command AT+CLCC shows active call even when a wrong number is called.	AT	OTHER
45835	If user configures CGAUTO different from default value (3), it is impossible to answer to an incoming GSM voice call (automatic or manual).	AT	OTHER
47805	If an OPEN AT^® application is started and when the user establishes a GPRS call, the +ILRR indication is returned by Wireless CPU^® after the call (i.e. after the NO CARRIER indication) and not before the switch in data mode (before the CONNECT indication).	AT	OTHER
49812	If a port, where the auto answer has been configured (ATS0), is closed, the auto answer value is reset to zero.	AT	OTHER
52024	As a response to "AT+WGPRS=?" command, the PDP context identifier should be in the range of 1-4 and not in the range of 0-4.	AT	OTHER
52081	Wireless CPU^® can reset if user wants to enter in DATA mode or exit from DATA mode on a closed port.	AT	OTHER
53004	Audio (Melody) is stopped when a Call Waiting indication is received for the second incoming call over an ongoing call. No melody is heard after the BEEP sound of the Call Waiting indication as the audio resource SPEAKER is now allocated to Call Waiting indication and context for audio (Melody) is lost.	AT	OTHER
53529	When AT+CFUN is sent from 0x80 and UART1 is closed using AT+WMFM=0,0,1, then just after initialization data abort error occurred. This is due to fact that when we try to get context for UART1 the firmware returns NULL.	AT	OTHER
53848	When repeatedly sending blocks of data for some time with AT+CPOF sent through an application at regular intervals the Wireless CPU^® hangs up and does not responds to AT commands.	AT	OTHER
40680	On deleting an entry while FDN to ADN swap is in progress, the module goes in hang state. No further AT commands can be processed in this state.	AT	PHONEBOOK
41928	When ME phonebook is full and SIM phonebook has 127 entries, module resets immediately after entering the PIN code.	AT	PHONEBOOK
41953	When an entry from the LND is displayed, sometimes the name field of the entry is missing.	AT	PHONEBOOK
41967	When the format used to search a phone number into a phonebook is not the same as the stored number, the AT+CPBP command does not list the matching entry.	AT	PHONEBOOK
42185	When the flash phonebook is full with all the entries with the same name, the Wireless CPU^® resets when we try to delete some entries.	AT	PHONEBOOK
48610	Although, the phonebook record has not been changed, the phone book status is wrongly displayed in "+WIND 10" indication.	AT	PHONEBOOK
51561	ATDxxxxpxxxxxxxxxxxxxxxxxxxx; calls the number with the DTMF Sequence and this sequence is stored in the LND phonebook wrongly reserving an EXT Record as DTMF sequence (after 'p') should not be stored in the LND phonebook. When the user again dials a similar sequence, the number is not stored in the LND as the EXT record has been reserved by the LND for the previous dialed number.	AT	PHONEBOOK
54033	When the size of the phonebook object is set with 0xFFFF in the Wireless CPU^®, a watchdog reset is observed few seconds after the SIM PIN code entry (if the SIM PIN code check is enabled) or few seconds after the SIM insertion (if the SIM PIN code check is disable).	AT	PHONEBOOK
41955	SMS present in ME is not displayed correctly in PDU format when PCCP437 character set is selected.	AT	SMS
41992	When the Wireless CPU^® is configured to display and record the SMS-STATUS-REPORT, several +CDSI indication are displayed and saved into memory for the same SMS (instead of only one per SMS).	AT	SMS
48617	If a user send or write the SMS with DCS as default GSM and store it in ME memory, then the SMS data when read is not displayed correctly. The bytes in the user data field got changed. This problem is not reproducible when SM memory is used.	AT	SMS
51793	When a get input is received with @ (i.e 0x00) in the text string, only the characters before the @ are displayed. It is because the intermediate response can only display a null-terminated string.	AT	STK
53962	When SIM Tool Kit feature is activated (see +STSF command description) and if an application requires the SETUP MENU using AT+STGI=0 command, the OK response to the command is returned after 2 +STGI response even if more +STGI responses have to be returned by the Wireless CPU^®. These indications are then returned as unsolicited responses instead of intermediate response. All +STGI indication for SETUP MENU should be returned as intermediate responses.	AT	STK
53506	Power consumption does not reduce in off mode after the AT+CPOF command is issued from Open AT^® application.	DEVICE	ADC/BAT
49559	Using AT+W32K=1,0 and AT+CMUX AT commands to authorize Slow idle mode on enabled CMUX com port and ignoring DSR state, the Wireless CPU^® does not enter low power mode.	DEVICE	MUX
41981	When an Open AT^® application is running, indicating on which unsolicited response a RI PULSE should be made using +WRIM does not work and RI pulse is not working. Currently, if bit 16 of 2nd parameter of +WRIM command is activated, RI pulse will happen for all unsolicited response when an Open AT^® application is running. The behavior should be the same than when no Open AT^® application is running : selecting specific unsolicited responses on which RI pulse is made should work when an Open AT^® application is running.	DEVICE	V24
54153	In case the Wireless CPU^® is in sleep mode the customer is not able to notice the mode as sleep mode because the CTS signal does not follow the DTR signal. CTS signal should not follow the DTR signal in case of normal mode but in case of sleep mode the CTS signal should follow DTR signal.	DEVICE	V24
51372	When the startTime option is used in monitoring (using IDS), the monitoring parameters which use timer does not work properly.	Embedded RDMS	RDMS
52346	When an update package tries to be downloaded by a device using IDS services and when the user agreement for download is activated, a "+WDSI: 2" indication is returned by the device. If the application decides to launch another IDS session with the server using AT+WDSS=1,1 instead of responding to the user agreement using +WDSR command, the download is made. In this case, the response to +WDSS command should be OK, a new "+WDSI: 2" indication should be returned indicating that the user agreement for download is requested and the package should not be downloaded.	Embedded RDMS	RDMS
52636	When a manual fallback is asked with the +WDSF command whereas no install succeeded before, the manual fallback should be failed and +WDSF should be answered an error.	Embedded RDMS	RDMS
53965	When the URL set in internal e2p is wrong, the Wireless CPU^® doesn't display any +WDSI indications, or it displays a +WDSI: 4 indication (it shouldn't, no socket is opened).	Embedded RDMS	RDMS
54016	Using IDS service, the Wireless CPU^® can send an automatic report to the IDS server when a trigger is configured for coverage. When the triggered value is reached, the value sent to the IDS server can be out of range (range = [0-100]). The value should be always in range and correct. Workaround: On server side, when an automatic report is received for coverage in case of trigger, a GET command can be requested for coverage (the value is always correct in this case).	Embedded RDMS	RDMS
41900	Slow network synchronization when no antenna is connected.	HWL	RF
41903	In the RTE mode, with some applications which use the ADL API frequently (e.g. to send/receive a large amount of data), the application should sometimes stop on an assertion failure (afxtempl.h file, line 666). Most of time, using the "Ignore" button should allow the application to go further.	OTHER	OTHER
47870	When attempting to use simultaneously CS2 & ADD25 signals (which are multiplexed on the same pin) no error is given to the ADL application.	OTHER	OTHER
48161	Interrupts raised with a frequency higher than 1kHz lead to a watchdog reset as soon as a flash memory erase operation occurs.	OTHER	OTHER
52295	TCU Capabilities indicate that no event capture or detection pin is available in fact two pins are available for the customer applications.	OTHER	OTHER
53196	In Telemetry sample, before writing into flash, the flash handle is not subscribed (there is no usage of "adl_flhSubscribe()"), this causes problem while saving the parameter via custom command +IOSET and +TEL.	OTHER	OTHER
49719	Even if the IDS feature is in prohibited state (see +WDSG command), if the firmware was downloaded in the WIRELESS CPU^® using a WPK, the IDS related flash volume is allocated (one 64kB sector for a 32Mb flash and four 64kB sectors for a greater capacity flash). Then, AT+WOPEN=6 command sets and returns the size of DOTA+DS volume and not only DOTA one.	OTHER	OTHER
54248	If only one frequency is available in the RF environment, in Autoquadband configuration, the application fails to register.	HWL	RF

4. Interface modifications

This section lists the interfaces that have been modified from the Open AT^® Firmware 7.3a.

API	Comment
AT+CPLS=?	AT+CPLS=? command returns the possible value for preferred PLMN SIM file. If PLMNwAct SIM file or PLMNSel SIM file is present in the SIM card, AT+CPLS=? returns 0 in the response. If these 2 optional SIM files are not present in the SIM card, AT+CPLS=? command still returns 0 value. In this case CME ERROR: 3 is return now.
AT+CPOL	The AT+CPOL had been updated in order to manage a PLMN list up to 700 entries. Some specific error codes have been created when this command is interrupt by a power off (CME ERROR: 555), a SIM removal (CME ERROR: 556) or an auto-answer (CME ERROR: 562).
AT+STSF	A new mode is provided for the AutoMode parameter to offer the Silent Mode. When the silent mode is activated, the auto response mode is activated and no +STIN and no +STGI indications are returned by the Wireless CPU^®.
AT+WDSS	When no dedicated NAP is defined using +WDSS command and a session is asked (by AT command or SMS notification), the Wireless CPU^® will used a NAP defined by +CGDCONT command to activate the dedicated PDP context.
AT+WDWL	The AT+WDWL command had been updated to allow launching a 1K-XModem download over UART 2 and USB (in addition to UART1).
AT+WHCNF	The AT+WHCNF command had been updated in order to provide the new mode (mode 4) allowing to select the InSIM or the external SIM card for WIRELESS CPU^® embedding an InSIM.
AT+WMBS	The AT+WMBS command had been updated in order to provide a new band (band 7) allowing to do a cell selection on the 4 GSM bands.
AT+WOPN	The AT+WOPN command had been updated to manage “correctly” wild card and the name of an operator is well associated if a wild card is present in the MNC code.
ATI	The ATI command had been updated in order to provide a new mode (mode 9) used to retrieve some details on components (Downloader, Firmware, Open AT^® application) loaded into the WIRELESS CPU^®.
AT+WDSA	It is not possible to shift DM server account by AT command, so the command had been deprecated. To change account are managed with credentials.

5. Corrections & Improvements

Id	Description (What / When)	Impacted Domain	Impacted Sub Domain	Fixed in
53326	The OPEN AT^® application using old Task Init "wm_apmCustomStackSize" can fail on start-up, when u16 value just given after address of wm_apmCustomStackSize differ from 0 (linker dependent).	SYS	INIT	Firmware 7.4
52754	Data abort happens if an external interrupt occurs (on FIQ) when an ADL functions is called.	SYS	ISR	Firmware 7.4
52210	Stuck in command mode after +++ when using UART PPP bearer.	OTHER	OTHER	Firmware 7.4
52243	wip_netExit () API does not release the memory resources allocated by the API wip_netInit () successfully. Memory leak can be observed by debugging the Open AT^®application in remote mode.	OTHER	OTHER	Firmware 7.4
53645	User controlled PLMN selector list is not taken into account because the list was added into the wrong address.	OTHER	OTHER	Firmware 7.4
53833	Impossible to perform a call when the spy mode is left.	GSM	MM	Firmware 7.4
52830	Using IDS services, the customer application can request an user agreement before downloading any update package. In this state, when the Wireless CPU^® is not registered to the network and when the customer application accept to download the update package using +WDSR command, the Wireless CPU^® returns an OK response but the download is not launched. The Wireless CPU^® should return an error (+CME ERROR: 651) in this case because it is not possible to launch the download.	Embedded RDMS	RDMS	Firmware 7.4
52948	When the inserted SIM supports the PLMNwAct SIM file (user preferred PLMNs with access technologies), getting it using IDS services is not possible. The Wireless CPU^® sends an empty list to the IDS server. This list is well sent to the IDS server when the SIM support the PLMNSel SIM File. The user preferred PLMN list should always be sent to the IDS server whatever the inserted SIM	Embedded RDMS	RDMS	Firmware 7.4
53180	Using IDS server, the IDS server can update the APN used for the IDS PDP context on the Wireless CPU^® by sending a SMS (Sent APN feature on the IDS Web portal). If this SMS is sent to the Wireless CPU^® before its registration on the server, this SMS is well treated. If this SMS is sent to the Wireless CPU^®(r) after its registration on the server, this SMS is not treated. This SMs should be treated in all cases.	Embedded RDMS	RDMS	Firmware 7.4
53562	When a WIP session is in progress and an IDS session occurred, the end of the IDS session (deactivation of the PDP context) provoke an error on WIP interface ( WIP_CERR_NETWORK_UNREACHABLE occurred)	Embedded RDMS	RDMS	Firmware 7.4
53573	If the command AT+WDSS=1,0 is done just after the response of AT+WDSS=1,1 command, the Wireless CPU^® may reset	Embedded RDMS	RDMS	Firmware 7.4
53597	When an error occurs during a PDP context activation (the error must be different from a bad NAP configuration), the AT+WDSS command does not respond.	Embedded RDMS	RDMS	Firmware 7.4
53672	Using IDS services, an Open AT^® application can subscribe to monitoring mechanism. This application can configure the monitoring for each own parameter. When a trigger is configured and when this trigger is reached, the device makes a reset and the automatic report is not sent. The device should not reset and send the automatic report to the IDS server.	Embedded RDMS	RDMS	Firmware 7.4
53703	Using IDS services, parameters can be configured to send automatic report to the IDS server when a triggered value is reached. Moreover, an hysteresis can be configured. If this value is negative, the Wireless CPU^® changes it to positive value (-9 is replaced by +9). The Wireless CPU^® should not change the value sign! This implies that automatic report on hysteresis is not available	Embedded RDMS	RDMS	Firmware 7.4
53704	Using IDS services, parameters can be configured to send automatic report to the IDS server when a triggered value is reached. Moreover, an hysteresis can be configured. If this value is equal to 0, the Wireless CPU^® does not take into account this value. This implies that automatic report on hysteresis is not available. This mechanism should be available	Embedded RDMS	RDMS	Firmware 7.4
53371	Wireless CPU^® reset occurs during Edge transfer on IDEA network using WIP.	EGPRS	RLC	Firmware 7.4
52847	When reading on I2C bus in a loop, Wireless CPU^® freezes.	DEVICE	IOB	Firmware 7.4
52254	The function adl_busSubscribe () for the parallel bus does not work properly when selecting the CS2.	AT	OTHER	Firmware 7.4
53017	According to 3GPP 27.007 specification, it should be possible to indicate an access technology in a user preferred PLMN using +CPOL command if the SIM support the PLMNwAct file. It's possible to read PLMNs with access technology but it's not possible to add a PLMN with an access technology	AT	OTHER	Firmware 7.4
53212	When we enable the OFFWHENUNPLUG feature and allocate any external interrupt to trigger the Wireless CPU^® power off, then when the state of the external interrupt changes the Wireless CPU^® is not powered off.	AT	OTHER	Firmware 7.4
53793	PTCRB 27.16 test is failed when SIM returns a Memory Problem error in a message. The Wireless CPU^® should return a dedicated response to the command. In this test, +CPBW command is used to add a phonebook entry in the SIM phonebook but no response is returned. In this test, a +CME ERROR: 13 response should be returned	AT	OTHER	Firmware 7.4
53811	The +CPOL? command allows an application to list PLMNs entries present in different SIM files. When +CPLS command is set to 0 (default value), entries listed by AT+CPOL? command are the ones present in PLMNwAct file or PLMN_SEL file. (If PLMNwAct is not present, PLMN_SEL file will be selected). If these 2 files are not present, AT+CPOL? makes a reset. +CPLS default value should be set according to SIM files presence. If no PLMN SIM files are allocated in the SIM, AT+CPLS? will return +CME ERROR: 3	AT	OTHER	Firmware 7.4
53868	SIM file 6F60 cannot be updated by AT+CPOL command because wrong record size is set. Record size 3 is used instead of 5.	AT	OTHER	Firmware 7.4
53660	Updated phone number is not displayed using AT+CPBR command, in case the user updates a phone number in the phonebook having adjacent 0's with a phone number such that the adjacent 0's are still in place before the first difference. The phone number is updated by removing the SIM, updating in another phone and then inserting the SIM again in the Wireless CPU^®	AT	PHONEBOOK	Firmware 7.4
41702	When "ME" are selected for SMS storage and read memories, when the Wireless CPU^® receive a concatenated SMS which contains a UDH (user data header) and data in UCS2 format, and when the text length of this message is odd, the PDU string returned to the application, using AT+CMGR command, is incorrect.	AT	SMS	Firmware 7.4
51817	When a SMS-PP data download is received by the Wireless CPU^®, the SIM may ask a refresh with a SIM reset. The Wireless CPU^® sends a detach to the network before the network acknowledges the SMS transmission.	AT	STK	Firmware 7.4
52361 and 52367	Second FAX call cannot be handled due to there is no terminal response send from ATI to OPEN AT^®. This cause further AT commands initiate by ADL are saved in the stack waiting for the answer of first ATA command. ATI should send a terminal response to OPEN AT^® with a new flag, so that OPEN AT^® can unblock the queue and the terminal response will not be displayed in the terminal.	AT	OTHER	Firmware 7.3a
47511	When 2 PPP sessions are opened on USB and UART1 (or UART2), when the USB session is released, the session on UART1(or UART2) is also released, it should not.	AT	OTHER	Firmware 7.3a
52150	Resuming a suspended Open AT^® application using an interruption is no more available from R61 FW version.	AT	OTHER	Firmware 7.3a
52208	Wireless CPU^® can reset in idle task (generally after starting).	AT	OTHER	Firmware 7.3a
52253	When a Nitz message is received with a negative local time zone, the computer hour is wrong (in the case of the automatic time zone update is set with the +CTZU command)	AT	OTHER	Firmware 7.3a
52297	If an outgoing CSD call is first accepted and then disconnected by the peer before receiving the CONNECT indication, further ATD commands from the Wireless CPU results in "+CME ERROR: 536". The call should be allowed and the error should not be received.	AT	OTHER	Firmware 7.3a
49881 and 50507	DTMF blank duration corrupted if user change its value during Wireless CPU^® is in airplane mode.	AT	OTHER	Firmware 7.3a
51564	The unsolicited responses after the Wireless CPU^® is powered off are not completely received by the customer application. For example, if "AT+WIND=255" and "AT+CREG=1" are set before, once the Wireless CPU^® is powered off (as described in "How to reproduce it" field), the unsolicited response "+WIND: 8" and "+CREG: 0" are not sent.	AT	OTHER	Firmware 7.3a
52152	Under atlas environment, after CPIN and AT++CMEE=1 commands are entered, AT+WDSA="" returns OK instead of +CME ERROR 3.	AT	OTHER	Firmware 7.3a
52156	Using +WDSH command, it is possible to define some host application in order to use IDS services for these applications. Declaring a host application when the IDS service is not in ACTIVATED state (see +WDSG command) makes a reset. This command should be allowed even if IDS services are in DEACTIVATED or TO BE PROVISIONED states.	AT	OTHER	Firmware 7.3a
52329	H command allows the application to release calls. This command accepts a parameter (which is 1 or 2). If this parameter is different from 1 and 2, the Wireless CPU^® does not return any response and all commands sent to the Wireless CPU^® on the same port will always return +CME ERROR: 515 response. +CME ERROR: 3 should be returned to ATHx command with x different from 1 and 2 and should not block the port in +CME ERROR: 515 state	AT	OTHER	Firmware 7.3a
51610	RI signal is pulsed when +WBCI unsolicited event occurred and +WRIM bit 14 is set instead of bit 6.	AT	OTHER	Firmware 7.3a
49475	When using the command +CPBW, the value of TON/NPI only allows 145 and 129. We need to support range from 128 to 255. Therefore, the actual definition of <type> should be: <type>: integer type; Type of address octet. (refer GSM 04.08 sub clause 10.5.4.7) 129 ISDN / telephony numbering plan, national / international unknown 145 ISDN / telephony numbering plan, international number 161 ISDN / telephony numbering plan, national number 128 - 255 Other values refer GSM 04.08 section 10.5.4.7	AT	PHONEBOOK	Firmware 7.3a
52417	+CMS ERROR: 538 is displayed when we try to copy all the messages in Flash to SIM. The SMS of the same replacement type are present in Flash and SIM memory. Also, for reproducing the issue the number of free locations in SIM SMS memory should be less than the number of messages to be copied from Flash.	AT	SMS	Firmware 7.3a
52869	Some junk characters are displayed in the +CMT indication in case the +CMT indication is enabled by the command AT+CNMI=2,2 on receiving a SMS.	AT	SMS	Firmware 7.3a
52251	After an UART3 opening and closing sequence, it is not any longer possible to open the UART3. Consequently customer applications opening UART3 should never close it.	DEVICE	USB	Firmware 7.3a
52740 and 53006	Using FCM API in Open AT^® application, no flow control configuration is set on the associated UART, receiving data on UART and having a lot of Wireless CPU^® load on data reception makes the Wireless CPU^® reset.	DEVICE	V24	Firmware 7.3a

51128	When an OPEN AT^® parameter is provisioned, a reset can occur.	Embedded RDMS	RDMS	Firmware 7.3a
51347and 52164	Open AT^®application may not be able to subscribe to 50 parameters for IDS monitoring. That is due to a memory overconsumption and it depends so on Application use cases. A reset will occur once the limit is reached. A possible workaround is to prefer the use of integer type parameters and if necessary to subscribe to buffer type parameters at the end of parameters subscription phase.

52232and 53072	When the SMS bootstrap are received to provisioned the NAP, the Wireless CPU^® resets.	Embedded RDMS	RDMS	Firmware 7.3a
52482	When a power off is made and the protocol stack is "hot" reset using AT+CFUN=1,0, the device can register to the network but no connection to the IDS server is available.	Embedded RDMS	RDMS	Firmware 7.3a
52495	Using IDS service, it is possible to configure a parameter in order to send an alert to the IDS server when a specific value is reached. If the triggered value is reached when the Wireless CPU^® is not registered on the network, the automatic report will be sent when the Wireless CPU^® is registered again on the network. However, the reported value is the current one (the last updated value). So if the parameter value was changed between the moment when the triggered was reached and the report, the reported value is not the right one. The reported value should be the value when the triggered was reached.	Embedded RDMS	RDMS	Firmware 7.3a
52497	When a device is created in the IDS server, according to the device model used for the creation, a SMS can be sent to the device in order to provision the APN to be used by the Wireless CPU^® in order to make a connection to the IDS server. This SMS is not treated by the Wireless CPU^® and stored in SIM. This SMS should be treated, should not be stored in SIM and no indication should be returned by the Wireless CPU^® to indicate that th
