Parameter Description

<mode>(num)

1	OTA (Firmware update Over-The-Air).
	Sets SPI mode to replace the module's existing firmware with a new firmware

from a dedicated SPI flash memory. The new firmware is initially written to the SPI flash via GSM/GPRS, i.e., over-the-air. See AT^SSPI for further detail on the SPI mode. More information on over-the-air firmware update can be found in [11].

Before launching an over-the-air firmware update, take care that the USB cable is unplugged. This is necessary because both interfaces, SPI and USB, cannot be used at the same time. See also AT^SSPI.
