Currently I am trying to get GPS messages (NMEA) through MC7455 module. After powering up the module I have three ttyUSB interfaces. If I understood correctly ,
ttyUSB0 --> is for diagnostic functionalities
ttyUSB1 --> is for GPS
ttyUSB2 --> is for sending AT commands.
I tried seeing the output of /dev/ttyUSB1 through minicom, I didn’t see any NMEA messages. So,I tried to configure the GPS through AT commands
I used the following commands:
ErrCode = 15
After running the at command gpstrack I am getting the error code:15 which means error in fix. What should I do to get the NMEA messages.
Thanks & regards,
