How to start GPS on EM7565 - i need to get position/location from GPS module, but I don’t known how
have you tried that AT!GPSFIX command?
From time to time the response is “No carrier” or “no TTFF available”
I’m novice and I don’t know which GPS commands are required and about their order
I have a log for WP76 module to use AT!GPSTRACK command, I guess you can treat it as reference.

If you can, tell me what is absolutly needed to start GPS on EM7565 ?
Antenna for GPS, reference signal ? Maybe nothing …
antenna and satellite signal, otherwise, you cannot get gps fix.
Do you know how to receive invoice for AT command tester programme ?
no, i don’t know.
You can contact distributor.
What really means the message “No TTFF available” ?
FAILCODE 12 means time out for GPS search
Current time: 2020 10 16 4 09:20**:51**
2020 10 16 4 09:19:49 Last Fix Status = FAIL, FAILCODE = 12
2020 10 16 4 09:19:49 Fix Session Status = ACTIVE
No TTFF available
Maybe signal is not ok, satellite in view is not enough
thank you very much
step by step I slowly move forward
Do You know server names of mobile network operators to shorten the time needed to first find the GPS position ?
Do you mean agps?
I think you can see the product technical specification which says we can use SUPL or XTRA agps
