Hello team,
our newly built EC25-EUX module connects to the internet without any problems, but it does not want to provide GPS data. From the modem we get:
AT+QGPS=1,1
OK
AT+QGPSLOC?
+CME ERROR: Not fixed now
Looking for a cause, we found several forum posts where the firmware version was the reason. Could this also be the case for us?
ATI: Quectel EC25 Revision: EC25EUXGAR08A07M1G
Thank You

Hello Fermi, thanks for your question on forums
I think you execute the wrong AT command, here is the steps you can refer:
AT+QGPSEND //CLOSE GNSS
OK
AT+QGPS=1 //OPEN GNSS
OK
AT+QGPSLOC=1 //GET LOCATION INFORMATION
You need to wait for a while before obtaining positioning information for the module to obtain satellite data.
Problem solved:
in the design I missed to provide the phantom power supply for the GNSS antenna. Using an active antenna the EC25 got no signal.
Now with a bug fix the EC25 gets location data.
Thank You
