3.3.2 Restart BGS12

After startup BGS12 can be restarted as described in the following sections:

•

Software controlled reset by AT+CFUN command: Starts Normal mode (see Section

3.3.2.1).

•

Hardware controlled reset by EMERG_RST line: Starts Normal mode (see Section 3.3.2.2)

3.3.2.1

Restart BGS12 via AT+CFUN Command

To reset and restart the BGS12 module use the command AT+CFUN. You can enter the com-

mand AT+CFUN=,1 or 1,1 or 7,1 or 9,1. See [1] for details.

If configured to a fix baud rate (AT+IPR0) the module will send the URC "^SYSSTART" to

notify that it is ready to operate. If autobauding is enabled (AT+IPR=0) there will be no notifi-

cation. To register to the network SIM PIN authentication is necessary after restart.

3.3.2.2

Turn off or restart BGS12 Using EMERG_RST

The EMERG_RST signal is internally connected to the central GSM processor. Abrupt

“hardware” shutdown will accur when A low level for more than 1ms is applied to

EMERG_RST pin. BGS12 can be switched on by mean of ON signal after releasing

EMERG_RST.

Note: EMERG_RST is controlled solely cannot restart BGS12, it can only turn BGS12

off at the hardware aspect. If want to achieve restart module like RESET behaver, it

should control ON signal at the same time as described by following paragraph.

For the other solution that high level has always been applied to ON pin, triggering

EMERG_RST will set the processor and with it all the other signal pads to their respective
