5. Corrections & Improvements

5.1 WipSoft

Id	Issue Description	Fixed In
60150	On UART1, when trying to start or stop a GPRS bearer on any virtual port other than the virtual port on which GPRS bearer was opened, the OK response is received on the virtual port on which the GPRS bearer was opened instead on the same virtual port on which the command was issued.	WIP 5.42
60285	For MMS service, while using WIPSoft command AT+WIPOPT to attach the files, the embedded module gets reset if the total size increases more than 150Kbytes.	WIP 5.42
60271	Error is received while trying to upload/download a file with filename greater than 62 characters. However, the ‘filename‘parameter of ‘+WIPFILE’ command can take 128 characters.	WIP 5.42
43781	+CME ERROR:841 is received instead of +WIPPEERCLOSE when FTP session is closed by peer.	WIP 5.41
56102	No +WIPFILE indication received when using HTTP_POST method in AT+WIPFILE wipsoft command.	WIP 5.41
58000	+WIPPEERCLOSE indication is not received on closing the FTP channel manually using the command AT+WIPCLOSE=4,	WIP 5.41
59518	A new option has been added in AT+WIPBR to return detailed CME Error codes or a generic error (+CME ERROR: 812) in the case of GPRS set up is failure.	WIP 5.41
59551	Reset is observed if an attempt is made to establish a POP3 session over an index value greater than 9 using the AT+WIPCREATE command.	WIP 5.41
57579	After the local SIM is removed and the remote SIM is inserted while GPRS setup is in progress, the WIP bearer startup for the remote SIM fails and no notification or WIP plug-In event is sent for the same.	WIP 5.41
58253	When SIM is removed, WIP_BEV_STOPPED event is not sent out when GPRS bearer is started using WIP.	WIP 5.41
50608	In the case of GPRS set up is failure, WIP now returns specific error codes instead of a generalized event (WIP_BERR_GPRS_FAILED).	WIP 5.41
52249	The "+WIPPEERCLOSE" unsolicited indication is not received when the FTP channel is closed by the server due to time out.	WIP 5.41
54171	When an error is generated on a TCP Channel, wip_getOpts() returns the correct error code in WIPLib but error code is not correctly displayed by WIPSoft.	WIP 5.41
56731 58865	Reconnecting to the Embedded module from Windows PC using PPP bearer fails even when WIP_BOPT_RESTART is set TRUE . Windows pops up Error:777 after attempted to reconnect.	WIP 5.41
59853	Ethernet controller may not be stable when AHB (Advanced High-performance Bus) clock of the Embedded module is increased from 26Mhz to 52 MHz (using AT+WCPS). This is because the C-Ethernet plug-in SPI bus runs at 26MHz instead of 13MHz but the Microchip chip supports only upto 20MHz.	WIP 5.41
57526	+CME ERROR: 847 is not received when the timer expires while trying to connect to GPRS bearer using WIPSoft.	WIP 5.40
57583	Peer port is displayed as 0 in +WIPDATA indication for UDP protocol.	WIP 5.40
56324	OK is not displayed when socket command subscription is successful.	WIP 5.40
57230	To prevent data corruption, MMS Transaction ID buffer has been increased from 10bytes to 11bytes.	WIP 5.40
57462	Repeated GPRS bearer start and stop along with stack open and close leads to module reset.	WIP 5.40
57504	User receives +CME ERROR:847 and bearer gets disconnected when AT+WIPBR=4,6,0 command is given at the time GPRS bearer is already connected. Ideally, only +CME ERROR:803 should be received and not followed by +CME ERROR:847, when user attempts to start the GPRS bearer at the time the bearer is already connected. The GPRS bearer should not get disconnected after 2 minutes on such an attempt.	WIP 5.32
54436	On giving the command AT+WIPBR=2,6,, where =12/13/14/20 and value=alphabet/negative, user receives +CME ERROR: 800 instead of +CME ERROR: 801.	WIP 5.31
56360	WIP_BERR_NO_DEV error is received while opening Ethernet bearer with RVDS binary. It works fine with GCC compiled binary. User should not get this error irrespective of compiler being used i.e. GCC or RVDS.	WIP 5.31
56883	Creating and closing the HTTP sessions consecutively for sometimes causes Embedded module to reset. This is due to memory leak while opening and closing the HTTP Sessions.	WIP 5.31
53515	It is not possible to send data through UDP client socket in the continuous data mode, using WIPSoft application compiled on RVDS compiler. The Embedded module gets reset. Ideally, user should be able to exchange data over UDP socket using application compiled on any of the compilers: ADC/GCC/RVDS.	WIP 5.31
54615	When AT+WIPBR command is issued with "invalid value" for the option WIP_BOPT_LOGIN, OK response is received instead of +CME ERROR: 801. Note that this command is given after starting the stack (AT+WIPCFG=1) and opening the particular bearer (AT+WIPBR=1, 6).	WIP 5.31
54984	The user cannot retrieve the IP address values set through +WIPBR command, before or after starting the bearer. Ideally, the user should be able to retrieve the IP related values after starting the bearer.	WIP 5.31
55050	Using WIPSoft, the unsolicited indications +WIPDATA, +WIPACCEPT, +WIPFILE and +WIPREADY are not received on all the ports opened (USB, CMUX and UARTS). Ideally, these unsolicited indications should be received at all open ports.	WIP 5.31
53459	When wip_putfile () API is provided with invalid file path for FTP protocol, the event WIP_CEV_OPEN followed by WIP_CEV_WRITE event are received in the file data handler. The ideal behavior should have been receiving WIP_CEV_ERROR in file data handler. Note that, this behavior is observed only in passive mode of FTP and not in case of active mode FTP.	WIP 5.30
53549	The "WIP_BEV_STOPPED" event is not received when Ethernet bearer is stopped using wip_bearerStop () API.	WIP 5.30
54452	After activating PDP context with CID 1 with WIP bearer APIs, then the dialing ATD*99**2# with CID 2 freezes the dialing process. It is not possible to open another PDP context when bearer is started using WIP Plug-In.	WIP 5.30
54671	It is not possible to perform operations such as set or get options through an Embedded application, compiled with RVDS compiler. The error -998 is received from WIP Library. Ideally user should be able to perform the above operations on RVDS also, as already being able to successfully perform on other two compilers: GCC and ADS.	WIP 5.30
54982	User will not be able to create a socket after starting the Ethernet bearer, when DHCP is disabled. Ideally, user should be able to create a socket for both the cases: DHCP enabled or disabled.	WIP 5.30
55022	It is not possible to create a socket after starting the Ethernet bearer, "+CME ERROR: 803" is attained. Ideally the user should be able to create a socket after starting Ethernet bearer, irrespective whether DHCP is enabled or disabled.	WIP 5.30
56419	When mail is downloaded using POP3 protocol and WIPSoft application, data gets corrupted. Some characters are missing from the downloaded mail.	WIP 5.30
