Quectel MC65 GPS fail(empty response)
I am using Quectel's MC65 to get location info.
Here is my at command process:
1-AT+QGNSSC=1\r
2-AT+QGNSSRD=\"NMEA/RMC\"\r"
The GNSS powers up correctly but I only get +QGNSSRD: OK in response!
Solution
It turned out I had connected the GNSS and AUX communication ports wrong. It should be
GNSS_RX--->AUX_TX
and
GNSS_TX--->AUX_RX(I am using ALL_IN_ONE mode).
It's sort of common sense and it's a bad mistake but this might help someone debug his/her system.
