5. Corrections & Improvements

ID	Description (What / When)	Impacted Domain	Impacted Sub Domain	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.	WIPSoft	OTHER	WIPSoft 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.	WIPSoft	OTHER	WIPSoft 5.42

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.	WIPSoft	OTHER	WIPSoft 5.41
59569	WIP Plug-in component information is incorrect in WIPSoft. It is displayed as "foo Plug-in Package" with an incorrect version number.	WIPSoft	OTHER	WIPSoft 5.41
56411 58873 58874	Compiling a C++ application using WIPLib as Plug-in fails. Compilation errors are received as some structure fields in a WIP header file are named as Sierra Wireless defined data types. Workaround: use u32 _u32; s32 _s32; in WIP header file.	WIPLib	OTHER	WIPLib 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.	WIPLib	OTHER	WIPLib 5.41
58253	When SIM is removed, WIP_BEV_STOPPED event is not sent out when GPRS bearer is started using WIP.	WIPLib	OTHER	WIPLib 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	OTHER	WIP 5.41
59121	When compared against iDE v1, stack size allocated in WipSoft application (compiled in RVDS and ADS) has increased when built using Developer Studio.	WIP	OTHER	WIP 5.41

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.	WIPSoft	OTHER	WIPSoft 5.32
54436	On giving the command AT+WIPBR=2, 6, <opt num>, <value> where <opt num>=12/13/14/20 and value=alphabet/negative, user receives +CME ERROR: 800 instead of +CME ERROR: 801.	WIPSoft	OTHER	WIPSoft 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).	WIPSoft	OTHER	WIPSoft 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.	WIPSoft	OTHER	WIPSoft 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.	WIPSoft	OTHER	WIPSoft 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.

WIPLib	OTHER	WIPLib 5.30
53549	The "WIP_BEV_STOPPED" event is not received when Ethernet bearer is stopped using wip_bearerStop () API.	WIPLib	OTHER	WIPLib 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.	WIPLib	OTHER	WIPLib 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.	WIPLib	OTHER	WIPLib 5.30

54438	For AT+WIPCREATE command (UDP) having port number with odd number of digits (within port range 1-65535) +CME ERROR: 800 are returned. Also, for port number out of bounds but having odd number of digits +CME ERROR: 800 is returned instead of +CME ERROR: 832.	WIPSoft	OTHER	WIPSoft 5.21

37108	When creating a socket with the wip_create() (wiplib) or AT+WIPCREATE (wipsoft) just after the call of wipclose() (wiplib) or AT+WIPCLOSE (from wipsoft) of that socket (same address and port) , that created socket cannot function properly as expected because the socket closing needs time and is not immediate. Workaround: The socket open call should not be called just after a socket close call: After a call to wip_close() or AT+WIPCLOSE to close a socket, a delay of one second is necessary before calling again the wip_create() or AT+WIPCREATE to open a new socket. If due to that asynchronous process the socket open call is too close to the socket close call and that issue is encountered, another workaround is to close and reopen that socket.	WIPSoft	OTHER	WIPSoft 5.11
47468 41712	Data is lost while large chunk of data is sent/received for TCP and UDP protocol	WIPSoft	OTHER	WIPSoft 5.01
