EC200U Version EC200UCNAAR03A13M08 – GNSS Not Starting / No Fix

:puzzle_piece: Post Body:

Hello,

I’m using a Quectel EC200U-CNAA module with the following firmware:

ATI
Quectel
EC200U
Revision: EC200UCNAAR03A13M08

I’m trying to use the internal GNSS engine using the following AT commands:

AT+QGPS=1         → OK  
AT+QGPS?          → +QGPS: 1  
AT+QGPSLOC=2      → No response or timeout  
AT+QGPSCFG?       → +CME ERROR: 501  
AT+QGPSGNMEA="GGA" → No data

However, GNSS engine doesn’t seem to start properly. The response:

+QGPS: "firmware",0,0

…suggests the GNSS engine is not enabled or not supported in this firmware.

Can someone from Quectel or the community confirm:

Whether GNSS is supported in EC200UCNAAR03A13M08 firmware?

Any help or firmware upgrade info would be appreciated. Thanks!

Please send

And if still not working maybe you can try the passive atenna.
