RAK5860 WisBlock Nb-Iot GPS


I tried to get the GPS data with this module (Quectel BG77) using the AT commands without any success.

The AT+GPS=1 give me OK, but the AT+QGPSLOC=2 always return a +CME ERROR: 516 //Not fixed ! error.

Same sequences of commands I used with my RAK5010 (BG96) without any issue…

I missed something to set ?


From the Quectel documentation I understand that GPS on the BG77 has a conflict with normal usage.

But I have no example how to solve it.

Hi Bernd

Thanks for the documentation link. I will try to find one solution…
