i have tried to use our first direct ip modem (MC7710) on our embedded device running kernel 3.2.
The modem (building up a connection to the provider) works fine but i cannot get any gps output.
Our previous card was the MC8790 which gave us severel serial ports (ttyUSB0 to ttyUSB6) i think. The MC7710
(detected as 1199:68a3 on the usb bus) gives us several usb ports too (ttyUSB0 to ttyUSB4) but no port allows us to receive gps data like the MC8790.
On a Windows 7 PC i can use this card like the MC8790:
- Open the AT-Command-Port in a terminal and enter the at!gpstrack command
- Open the NMEA-Port in a terminal and i receive the gps data
And yes, gps is enabled i think because the at!gpstrack command sends no error code, only OK
( I already enabled gps by entering the at!entercnd=“XXXX” and at!custom=“GPSENABLE”,1 command…)
Has someone an idea why this isn’t working?
I tried this card also in qmi mode without success (changed the pid to 68a2).
The driver version is 1.7.40. (sierra.c).
Both modules (sierra.ko and sierra_net.ko) are inserted.
Thanks in advance and best regards
