Internet Library 5.41 Release note

Oct 01, 2010 - Author: Sierra Wireless - Version 5.41 - 3469 Views

1. New Features

This section lists the features added from the previous Internet plug-in 5.40.

CME Errors in WIP/WIPSoft for AT&T device aggressions tests: In case GPRS setup failure is observed, WIP now returns specific error codes instead of a generalized event(WIP_BERR_GPRS_FAILED).

MMS improvements now support:
  • Sending to multi-recipients
  • Several attachments and multipart related content.
  • List of supported format:
    • Audio (AMR, WAV, AAC, AC3, AIF, AIFC, AIFF, FLAC, MP2, MP3, RAW, OGA, OGG, SWA, VOC, WMA)
    • Image (GIF, JPG, JPEG, PNG, SVG)
    • Video (AVI, FLV, MOV , MKV, OGM, VOB, WMV)
    • Text (TXT) in ASCII (US, FR, EN) and UCS2
    • Multimedia Presentation (SMI, SMIL)
    • AT commands interface available
    Retransmission configuration: AT+WIPCFG command now gives the ability to manage the maximum number of retransmission and its timeout while sending data packets.

    Port forwarding: This additional Gateway feature ease WAN to LAN interconnection by giving the ability to manage incoming requests from public area (WAN) to private area (LAN) by matching relevant public port to private port.

    Data Offline: User data can be sent or received through an AT Command and unsolicited over a serial link in AT mode (off-line mode) for TCP/UDP sockets, FTP, SMTP and POP3 services.

    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

    57462 Repeated GPRS bearer start and stop along with stack open and close leads to module reset. WIPLib OTHER WIPLib 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.    		 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
    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. WIPSoft OTHER WIPSoft 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. WIPSoft OTHER WIPSoft 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. 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
    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. 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

    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.
