Hello
in AT manual is stated, that after AT+QGPS=1 NMEA can be read from GNSS serial port, in my case /dev/ttyUSB1 (Linux)
On the modem RM520NGL AA R03 it is not works, 1st activation give an +CME ERROR: 504 (which is normal, when GNSS already active, but it is not).
On earlier revision R01 it is working fine. (tested on RM520NGLAAR01A08M4G)
Any clues? Do I need a firmware fix or the command is changed?
Regards, Peter

Dear @batcilla
