Mc60 GNSS power on

Hey I am using mc60 for location tracking , that is serially connected with controller and when I send AT+QGNSSC=1 gnss should get on but it does not happen it gets on when I repeat this command 3 times and also when debugger is connected ?

Dear Sir,
Whether there have any error information when you send AT+QGNSSC=1 ?It is better to provide more information to us, such as your connection, module FW version, AT test log, etc , then we can judge where is the problem.Thanks!
