3.4.2. Airplane Mode

EG18 provides a W_DISABLE# signal to disable or enable airplane mode through hardware operation.
The W_DISABLE# pin is pulled up by default. Driving it to low level will make the module enter into
airplane mode.
In airplane mode, RF function will be disabled. The RF function can also be enabled or disabled through
AT commands. The following table shows the RF function status of the module and relevant AT
commands.
