to full functionality. This is a useful approach because, in this mode, the AT interface is not accessible.
Examples
EXAMPLE 1
To check the level of functionality use the read command:
AT+CFUN?
+CFUN: 1

AT+CFUN?
+CFUN: 5
EXAMPLE 2

After this, you may want to verify the operating status:
AT+CFUN?
+CFUN: 1
EXAMPLE 3

+CFUN: 5
OK
AT+CFUN=1
OK
Remember that this approach is not applicable to the NON-CYCLIC SLEEP mode (since the serial interface
