3.5.2. Airplane Mode

EG12 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 low will let the module enter airplane mode.
In airplane mode, the RF function will be disabled. The RF function can also be enabled or disabled
through software AT commands. The following table shows the RF function status of the module.
