AT+CGATT?
+CGATT: 0
OK
Query the GPRS status.
AT+CGATT=?
+CGATT: (0,1)
OK
Query the valid parameter values for
the command.
Remarks
By default, the module can automatically perform GPRS attach.
Ensure that the GPRS attach is set before the PPP connection is set up.
It is recommended that you add the
AT+CGATT?
command to the process
to query the GPRS status. If the module returns
1
, you can set up PPP
connection directly; otherwise, you need to set GPRS attach manually by
executing the command
AT+CGATT=1
.
