Send gps command to mc60 module

Hello there,

Need help in sending gps command:

ret = Ql_RIL_SendATCmd("AT+QGNSSCMD=0,\"$PMTK386,2*21\"", Ql_strlen("AT+QGNSSCMD=0,\"$PMTK386,2*21\""), NULL, NULL, 50) ;

I am not getting desired result. It showing ret 0 I am doubtful if am making some mistake.

Dear dev

Did you call “Ql_RIL_Initialize” before using “Ql_RIL_SendATCmd”?For details, see “quectel_Opencpu_RIL_application_note_V1.2. PDF” in the SDK package.Thank you.
