GPS
Configure module to use NMEA sentences, The GPS antenna has to connect to the GSM diversity TNC connector, so you cannot use the GSM diversity at the same time as GPS.
On the EHWIC card, there is a green LED for status, it can be used for troubleshooting. It will be off while searching and illuminate solid green once a GPS fix is obtained.
