1. New Features

The Extended AT 1.01 Application offers, in a single application, the combination of all WIP and GPS AT commands provided by:

  • WipSoft application, from WIP Plug-In 5.41, and
  • GPS_AT_cmd application, from Location Plug-In 1.1

1.1 New WipSoft Features

  • 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 WipSoft support and MMS improvements:
    -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)
  • TCP retransmission configuration: AT+WIPCFG command now gives the ability to manage the maximum number of retransmission and its timeout while sending TCP segments.
  • 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.

1.2 New Location Features

  • XM0110 I2C serial interface support, in addition to UART interface
  • Compatibility to Embedded Module sleep mode (32K mode) when using XM0110 UART serial interface (not available with XM0110 I2C interface)
  • PDOP and VDOP fields support (for both PVT and NMEA)
  • GPS AT command application default settings compatible to SL6087 development kit

      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,<idx>

      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, <opt num>, <value> where <opt num>=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.
