2.13.1.2 Power OFF
To properly power OFF the module, the application must set the ON/OFF signal
to low and then send the AT+CPOF command to de-register from the network
and switch off the module. Once the « OK » response is issued by the module,
the power supply can be switched off.

2.14 BOOT (optional)
This input can be used to download a software in the Flash ROM of the
WISMO Quik Q2403 Series module. For the applications based on AT
commands this is a backup download procedure only (see chapter Firmware
upgrade). The internal boot procedure is started when this pin is low during
the reset of the module. In normal mode this pin has to be left open. In Internal
boot mode, low level has to be set through a 1K
Ω
resistor. If used, this input
has to be driven by an open collector or an open drain.
