3.10.1. W_DISABLE1# Signal

EM12-G provides a W_DISABLE1# signal to disable or enable airplane mode through hardware
operation. The W_DISABLE1# pin is pulled up by default. Driving it to low level will let the module enter
into 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.
