Hi, I am new with Quectel EC25 module and I want some knowledge that how to use A-gps in EC25.
EC25 supports gpsOneXTRA Assistance Function, please refer to Quectel_EC25&EC21_GNSS_AT_Commands_Manual_V1.1.pdf for detail.
Thank you for your valuable reply but I already enabled that gpsOneXTRA assistance and the problem is that every time its taking 18-25 sec to get fixed and sometime not able to fix. So how to resolve this problem.
Please check whether there have any interference in your test environment. Please pay attention to that the GPS antenna should placed at half-open sky or open-sky environment.
By the way, you also can check the NMEA sentence to check the receiver tracking signals quality. Thanks!
