hello,
first sorry for my bad english.
I’m new at OpenAT and I spend few weeks reading documentations and trying some sample Applications.
I’m using an Evaluationboard with a Wireless CPU Q2687 with 663 Verion of Firmware.
The OS-Version is 4.21
I’m also using the Wip-Plugin Verion 3.10.2030
I’m writting my programcode in Ecipse with an gcc Compiler, as it comes as standard IDE with the SDK.
My aim is to establish a GPRS Connection and to subscribe to FCM on GPRS, so that I can receive incoming data to check them.
If there is coming some special data, other functions should be executed.
But at first I’ve got a problem with the FCM-Service and GPRS.
I trying to establish an GPRS Connection.
This works I think, but when I subscribe to the FCM with GPRS as Port I get some strange behavior.
And there is something else I’m bit confused about.
In the Target Monitoring Tool I get some Traces all beginning with “[GPRS]” which I’ve not written in my Code.
Are this standard Traces from the OS?
When I subscribe to the FCM-Service using GPRS Port, I’ve got the "FLOW OPENED’ - Event from my FCM-Control-Handler
but immediately after this I’ve got the “FLOW CLOSED”-Event.
Thereafter the GPRS Connection is closed, without any reason as far as I can see.
This is the way I tried:
-> First I’m subscribing to the SIM-Service
->when I get the event “ADL_SIM_EVENT_FULL_INIT” I subscribe to the GPRS-Service using the function ‘adl_gprsSubscribe’
then I’m sending the AT-Command “AT+CGATT=1” using ‘atCmdCreate’, because I want to attach to the GPRS-Network.
(I’m unable to find an equal function for this, so I can’t avoid using ‘CmdCreate’).
-> then when I receive the Event “ADL_GPRS_EVENT_ME_ATTACH” I’m starting an IP-Bearer using wip-function ‘wip_bearerOpen’.
then I set the Options for GPRS like APN and so on.
and at the end I start the Bearer with the command ‘wipbearerStart’
-> on the Event “ADL_GPRS_EVENT_ACTIVATE_OK” from my GPRS-Eventhandler I’m subscribing to the FCM on GPRS Port
-> when I get the “Event WIP_BEV_IP_CONNECTED” from my GPRS-Bearer-Handler I created an TCP-Client Socket using ‘wip_TCPClientCreate’
-> At last I get the “WIP_CEV_OPEN” Event

}There is maybe something wrong in this code, or I use the function and Eventhandler in a wrong order or something else.
I’m very thankful for any help.
Thank you for spending time reading my post.
Kind regards
