5.5. Power off UMTS<E and Wi-Fi Modules
Power off UMTS<E modules
There are two ways to power off UMTS<E modules.
One way is to execute AT command AT+QPOWD. This is the best and the safest way. The module will log
off from the network and save data before shutdown, but it will be powered on again after shutdown. For
more details about the AT command, please refer to document [5] or document [6].
The other way to power off the module is to press down S302/S301 button (S302 for
UC20/EC2x/EG9x/AG35/BG96 modules, and S301 for UGxx modules) for at least 0.6s.
Power off Wi-Fi modules
AT+QWIFI=0 command can be used to power off Wi-Fi modules. For more details, please refer to
document [3] or document [4].
