The module will be wakened up when USB_VBUS is restored to be powered.
3.5.2. Airplane Mode
When the module enters airplane mode, the RF function does not work, and all AT commands related to
RF function will be not accessible. This mode can be set via the following ways.
Hardware:
The W_DISABLE# is pulled up by default. Its control function for airplane mode, which is disabled by
default in software, can be enabled through AT+QCFG=“airplanecontrol”,1. When such a control
function is enabled, you can drive W_DISABLE# to low level to make the module enter airplane mode.
Software:
AT+CFUN = <fun> provides the choice of the functionality level through setting <fun> into 0, 1 or 4.
⚫ AT+CFUN=0: Minimum functionality mode (RF functions are disabled).
⚫ AT+CFUN=1: Full functionality mode (by default).
⚫ AT+CFUN=4: RF function is disabled (Airplane mode).
