AT command about +QLWEVTIND

The device has been successfully registered on the platform. Under normal circumstances, the module will reply +QLWEVTIND:3. Why does the module not reply to this command?I have used the AT+CGATT directive to query and return 1 (ATTACH)

Hi Customer,

  2. and please provide whole at log after module restart for me first.
