The following runs for me in continuous mode:

AT%XSYSTEMMODE=0,0,1,0

AT+CFUN=31

AT#XGPS=1,0,1 -> A fix every second. AT#XGPS=1,0,10 -> A fix every 10 seconds.

Hi Dejan,

Thanks for the reply. I tried to follow the steps you mentioned. Did both CFUN=0 and CFUN=4. both are replied with "ERROR" when I send "AT#XGPS=1,0,1,0". Is there something I am missing?

Can you please provide me the list of at commands in chronological order so that I can test it on my end.

Hi,

You could try to put the modem to minimum functionality (CFUN=0) or flight mode (+CFUN=4) first and then restore full functionality (+CFUN=1). Afterwards, you can use AT#XGPS=1,0,1,0 to start GNSS module and set the <interval> parameter to continuous navigation mode.

Best regards,
Dejan
