The power down procedure causes the module to log off from the network and allows the firmware to
save important data before completely disconnecting the power supply.
Before the completion of the power down procedure, the module sends out the result code shown below:
NORMAL POWER DOWN
1. When unsolicited result codes do not appear when autobauding is active and DTE & DCE are not
correctly synchronized after start-up, the module is recommended to be set to a fixed baud rate.
2. As network logout time is related to the local mobile network, it is recommended to delay about 12
seconds before disconnecting the power supply or restarting the module.
After that moment, no further AT commands can be executed. Then the module enters the power down
mode.
