OnCell G2150I AT Command Set General Commands
3-6
AT+CPOF). This command executes an IMSI DETACH and makes a backup copy of some
internal parameters in SIM and in EEPROM. The SIM card cannot then be accessed. If the mobile
equipment is not powered off by the application after this command has been sent, a re-start
command (AT+CFUN=1) will have to issued to restart the whole GSM registration process. If the
mobile equipment is turned off after this command, then a power on will automatically restart the
whole GSM process. The AT+CFUN=1 command restarts the entire GSM stack and GSM
functionality: a complete software reset is performed. All parameters are reset to their previous
values if AT&W was not used. If you write entries in the phonebook (+CPBW) and then reset the
product directly (AT+CFUN=1, with no previous AT+CFUN=0 command), some entries may not
be written (the SIM task does not have enough time to write entries in the SIM card). In addition,
the OK response will be sent at the last saved (AT&W) baud rate defined by the +IPR command.
With the autobauding mode the response can be at a different baud rate. It is therefore preferable
to save the defined baud rate with AT&W before directly sending the AT+CFUN=1 command.
