5.2.1î™–î™–î™–î™–Description
Selects the level of functionality <fun> in the MT.
SARA-R4 / SARA-N4
If the syntax +CFUN=15 or +CFUN=16 (resets) or +CFUN=127 is used, the rest of the command line, placed
after that will be ignored.
SARA-R4 / SARA-N4
A SW reset via AT+CFUN=1,1 triggers signalling attempts whose number is internally counted by the SW
and limited based on mobile network operators' thresholds. The AT&T RPM feature (see also the +URPM
AT command) limits the number of SW resets per hour, and might cause the AT command to return an
error result code.
