in difficult conditions it is possible that I can’t get a connection with:
at the first try (using GPRS).
Second possibility is, that the connection is shut down during operation due to lost GPRS connection.
In those cases i try to disconnect correctly via:
wip_close ( io_channel );
wip_bearerStop ( &bearer );
On wip_bearerStop i get an error.
So the question is, how to shut down the GPRS wip connection correctly.
I have tried several other sequences including wip_close, wip_bearerStop, wip_bearerClose without any luck but several RTK errors.
Thanks for your help
