I am using the wavecom supreme (OS Version 663c) with the latest WIP plugin (version 3.10.2033)
to run an application, which tries to access a web server after establishing a GPRS internet
The application works fine on the supreme without the expansion card.
However, when I insert the IESM expansion card, GPRS initialization (wip_bearer start) is much slower
and internet connection to the server sometimes fails, resulting in a WIP_CEV_ERROR message with a WIP_CERR_DNS_FAILURE code.
I do not make any use of the features provided by the extension board.
What could be the cause of this problem ?
