EC21 Enable GNSS Function and quectel-CM Problem

Dear all,

I am using the EC21 module, I tried to Turn on GNSS via AT+QGPS and also use the "quectel-CM " to connect the BS, and soon the connection will drop . How could I check this problem by AT command ?

Hi @john.lin
May I ask whether both QGPS and Quectel-CM will be disconnected or Quectel-CM will be disconnected. If it is connected separately, there will be no such problem?
