Internet Library 5.30 Release note

Jul 01, 2010 - Author: Sierra Wireless - Version 5.30 - 2192 Views

2.1. Software Identification.
2.2. Compatibility.


1. New Features

This section lists the features added from the previous Internet plug-in 5.2x.

DHCP server for WIPLib: embedded module can be used as a gateway between a LAN and a WAN through GPRS. By using DHCP server feature, this gateway can also manage IP address allocation for machines on the LAN. This feature is available in beta stage. For more information, please refer to DHCP server in WIP Connectivity Development Guide.

DNS proxy for WIPLib: embedded module can be used as a gateway between a LAN and a WAN through GPRS. By using DNS proxy feature, this gateway can provide a DNS service for machines on the LAN, thanks to a connection to a DNS server available on the WAN. This feature is available in beta stage. For more information, please refer to DNS proxy in WIP Connectivity Development Guide.

Id Description (What / When) Impacted Domain Impacted Sub Domain Submitted Date
ANO57230 Transaction ID buffer is currently 10 bytes, it should be 11 bytes to prevent data corruption. WIPSoft OTHER 2/10/2010 15:16
CUS56731 User is not able to re-connect from Windows Machine to Embedded module using PPP bearer even when WIP_BOPT_RESTART option is set TRUE. Windows pops up Error:777 on an attempt to reconnect. WIPLib OTHER 12/16/2009 14:18
CUS56368 WIP net init returns error -26 when called from task ID is greater than NETINT_MAX_THREADS. The returned error is not documented either in WIP UGD or WIP header files. WIPLib OTHER 11/5/2009 17:32

ANO56164 The Embedded module resets when network connection is lost during GPRS bearer stop. There should not be any reset on Embedded module, if network connection is broken during bearer stop. WIPLib OTHER 10/15/2009 12:34
ANO55094 User is not able to open the Ethernet bearer after restarting the IP Stack as Embedded module resets. Ideally user should be able to open the Ethernet bearer even after IP stack restart and there should not be any Embedded module reset. WIPSoft OTHER 7/17/2009 20:22
ANO55021 It is not possible to start the Ethernet bearer with DHCP enabled. Also with DHCP disabled, the Ethernet bearer does not get unsubscribed on removing the Ethernet cable. WIPSoft OTHER 7/14/2009 12:34

4. Interface Modifications

API Comment
wip_setOpts() wip_getOpts() wip_readOpts() wip_writeOpts() wip_netSetOptsv() Variable arguments of type va_list are now passed as reference (va_list * pargs). It impacts external WIP functions as wip_setOpts(), wip_getOpts(), wip_readOpts(), wip_writeOpts(), wip_netSetOptsv(). This has been done for RVDS compiler use. And that has implied the new generation of Security Plugin WipSSL

5. Corrections & Improvements

Id Description (What / When) Impacted Domain Impacted Sub Domain Fixed in
CUS57504 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
ANO53459 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. WIPLib OTHER WIPLib 5.30
CUS53549 The "WIP_BEV_STOPPED" event is not received when Ethernet bearer is stopped using wip_bearerStop () API. WIPLib OTHER WIPLib 5.30

CUS54452 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. WIPLib OTHER WIPLib 5.30
CUS54671 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

CUS56419 When mail is downloaded using POP3 protocol and WIPSoft application, data gets corrupted. Some characters are missing from the downloaded mail. WIPLib OTHER WIPLib 5.30

ANO54615 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
ANO54984 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
CUS55050 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

CUS37108 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.
