4.2. Power Off Mini PCIe Module
There are two ways to power off Mini PCIe module.
One way is to execute AT command
AT+QPOWD
(Refer to
document [2]
). It is the best and safest
approach. It logs off the network and saves data before shutdown. But Mini PCIe module will be powered
on again after shutdown.
The other way is to switch S201 (POWER) to OFF state directly, but this way is not recommended. Please
switch S201 to OFF after shutting down the module by executing AT command
AT+QPOWD
.
