At very high UART baud rates, embedded module may sometimes reset when +CPBN command is used repeatedly to read entries from “ME” phonebook.

AT

PHONEBOOK

57682

When Li-Ion algorithm is used on AirPrime WMP100 embedded SIM (with ATMEL WAP 3.1) to charge old batteries, charging maybe suddenly stopped (no more current draw) but charging indicator (+WBCI: 2, XXXX) continue to be displayed.
This problem can be solved by inserting a Schottky diode between power supply (charger) and module.

DEVICE

ADC/BAT

63793

Issuing AT commands on a CMUX DLC and uploading data using DUN on another CMUX DLC may lead to a data stall (CTS of the Embedded module goes high).

DEVICE

CMUX

59934
58510

AT commands cannot be issued to the Embedded Module over any DLC if sleep mode is enabled before CMUX session is established.

DEVICE

CMUX

56345

Data flows are often corrupted or interrupted if Embedded module is being used with two simultaneous data flow on the both UART in CMUX mode.

DEVICE

MUX

53820

Whenever UART2 is opened by Embedded application using ADL API at AUTO BAUD RATE, baud rate of the UART will get fixed after the first communication with hyper terminal or any other application. The baud rate will not get changed after that which will lead to an erroneous communication with different baud rates.

DEVICE

63524

Disabling of a USB port is allowed even if a CMUX session is open on USB port.

DEVICE

Data loss seen on UART when AT commands with very large input parameters entered repeatedly.

The Embedded module resets if a large DLE/ETX sequence is transferred using TCP/UDP socket which is created on UART or USB bearer using Internet Application.

Using AirPrime Management Services, the customer can activate a user agreement on the device (See +WDSC command description in the AT command UGD). This user agreement returns a +WDSI unsolicited indication. When a response is not returned by the customer application (using the +WDSR command), the +WDSI unsolicited response is returned again after 30 minutes. This +WDSI unsolicited indication is returned after 10 minutes instead of 30 minutes. Moreover, a new timer value for the next +WDSI unsolicited indication can be set by the customer application using the +WDSR command. Even if the timer value range is [0-1440], the maximum value set by the R7.51 is 19 minutes.

Embedded RDMS

RDMS

54016

Using AirPrime Management Services, the Embedded module can send an automatic report to the AirPrime Management Services server when a trigger is configured for coverage. When the triggered value is reached, the value sent to the AirPrime Management Services 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

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

Command AT+CGATT=1 gives wrong CME Error (+CME ERROR: 103) in case network rejects the attach request with cause “illegal ME”. Ideally, +CME ERROR: 106 should be received in this case.

GPRS

OTHER

62527

GPRS connection would become unstable /abnormal when MIC listening service is turned on simultaneously.

HWL

AUDIO

63130

During a SSL connection, embedded module gets blocked and does not respond to any AT command. This is because connection is done in highest priority task and the server certificate validation requires a long and heavy computation.
Workaround: The highest priority task in an embedded application should not do any heavy blocking computations unless really needed, since that will block AT commands. If the application needs to be responsive of AT commands, the connection should be managed from a task that is not the highest priority.

OTHER

OTHER

60832

When using GDB with maximum of allowed breakpoints (2), and pressing Step Return, Developer Studio will sometimes insert an extra (3rd) breakpoint. This will stop further GDB debugging session from working.
Workaround, do not use maximum of allowed breakpoints when doing step return.

After a FTP transfer is completed in boost mode (Embedded module at 104Mhz), the module gets out of boost mode and the Embedded module frequency is returned to 26MHz.

OTHER

OTHER

53799

The ADL_INIT_DOWNLOAD_ERROR error is received while trying to write into an already finalized A&D Cell. Error ADL_INIT_DOWNLOAD_ERROR is rightly returned as it is not possible to write into a finalized cell. The finalized Cell_ID should be deleted first in order to write into it and then used to download and install the application.

Embedded module may generates a +WIND: 0 (SIM extraction) before generating a +WIND: 1 (SIM insertion) when switching between remote SIM (available through OSA services) and local SIM.

SIM

OTHER

62622

When an UICC card is inserted, only USIM application can be selected (it is automatically done by the terminal). Other applications which may be present in file EF_DIR in UICC card (file containing the list of available applications) can not be selected.

SIM

OTHER

62619

If an UICC with USIM application is selected, following AT commands related to CPHS are restrained: +CPHS, +WALS, +WMBN. In such a case, +CME ERROR: 3 is returned.

SIM

OTHER

62621

Only 254 entries are available on USIM phonebook (as in SIM 2G) as only one ADN file can be managed. USIM should support more entries as USIM can support 4 ADN's.

SIM

OTHER

61695

While using USIM with embedded module, application phonebook is not supported, i.e. “AP” is not shown in response of AT+CPBS=? command.

SIM

OTHER

61627

While using USIM with embedded module, application phonebook is not supported. So if the UICC is inserted into a embedded modules accessing the ADN and EXT1 files; and a record in these files has been updated, and if the UICC is later inserted into a terminal that supports the global and/or application specific phonebook, a full synchronization will not be performed of the phonebook between an external entity and the UICC (if synchronization is requested).

SIM

OTHER

API

AT+WSAPPI

This proprietary command can be used to indicate if the active application is USIM or if the card is SIM one.

AT+CRSM

New field <pathid> introduced for USIM card.

ATI8

Displays revision identification used for product certification

ATI9

Added MODEM section in command response (corresponding to certification information)

AT+WOPEN

Value <9> added to configure File System Data Storage.
As firmware reserved space has been increased of 256kBytes, space available for OAT Application, and Data Storage have been reduced of this amount.

Interrupt Priority change feature, +WOPEN=7,21 is deprecated and shall not be used anymore

AT+WUSB

Default configuration for <idProduct> is now 0x1000 instead of 0x1234.
Default configuration for <iProduct> is now USB AS COM instead of USB Modem.

By default, USB is now mounted /detected as a COM port and not as a modem.

+++

Unsolicited responses are received after the OK when switching from data mode to AT mode using +++.

ATGH

This command now comes under command class “AT_CLASS_GPRS” instead of class “AT_CLASS_MAIN”.

AT+WECC

This new Sierra Wireless proprietary command can be used for specifying new Emergency Call Codes.

AT+W32K?

Read command for +W32k command is available now.

AT+WDSS
AT+WDSC

AT+WDSI

The auto registration and the MSISDN registration features of AirPrime Management Services are removed. The following AT commands are now obsolete:

AT+WDSS=2,

AT+WDSC=5,<Config>[,<ValidityPeriod>],

AT+WDSI=4095

Also unsolicited response +WDSI: 22 is deprecated.

+CPHS, +WALS, +WMBN

These commands are not available if UICC card is inserted with USIM activated application.

+CME ERROR: 515 is received, when an embedded application is running on embedded module and +WDSO command is sent in concatenation with other command from AirPrime Management Services server; it has to be sent alone first, then other commands can be sent (in one concatenate command or not) when the +WDSO response has been received on the server side. The same issue happens when the 1st command of the concatenated command is +WOPEN. Similar issue also happens when the command is sent on an external port.

Using AirPrime Management Services, the SMS counter in roaming is not correctly incremented when the device is registered in Roaming on a PLMN where the MNC is 0 (like HK_CSL network: MCC: 454 , MNC: 00) This SMS counter in roaming should be correctly increment on all network.
