May I ask you for some help with GPS of MC7710 (and MC8792v) modules.
We are using latest release of the firmware and we are using AT command port to get GPS information (!GPSLOC, !GPSSATINFO). This method works good, but we want to use NMEA port for GPS input.
The problem is, that we have no messages on NMEA port and we also can’t start tracking with !GPSTRACK message.
Here is the output from hyperterminal:
