i have executed all the at commands for fixing the location through EC200U module. but i coldnt get the actual location through this

2

What is the number of satellites being reported?

Please be specific about what “all the at commands” means, and what values you currently have set.

didn’t getting the actual location, i have tested this in open sky but there is no change…
need any other configurations

changed the at command at+qgpscfg=“gpsnmeatype”,1 to at+qgpscfg=“gpsnmeatype”,1

01/28/2022 11:49:53.095 → $GPRMC,V,N,V*29

from “GSV” NMEA sentence i think there is no satellite available… i have tested this in open sky but couldnt fix the actual location

I’ve just experimented with my RM500Q-AE, basically repeating tests I’ve done with other Quectels.

AT+QGPSCFG=“outport”
+QGPSCFG: “outport”,usbnmea
OK
AT+QGPSCFG=“autogps”
+QGPSCFG: “autogps”,0
OK
AT+QGPS?
+QGPS: 0
OK
AT+QGPS=1
OK

Wait about 10 seconds.

AT+QGPSLOC=2
+QGPSLOC:071339.00,-xx.23348,xxx.04281,1.4,566.3,3,0.0,0.0,280122,6
OK
AT+QGPSEND
OK
AT+QGPSLOC=2
+CME ERROR: 505

Lat/Lon obscured by me. Six satellites found quite quickly, using default values for most parameters.

Reported altitude of 566 metres is well on the way to being accurate for my location.

Do you have better luck using the AT command AT+QGPSLOC=2 to read your position?

It might help identify the problem area.

I waited for 45 min to get the exact gps location… but still didnt get the actual value

6

Do you have a suitable antenna connected to the ANT_GNSS pin?

That was antenna issue. the antenna requires an external power supply for proper functioning. after implementing the same my device working good
