3.10.1. W_DISABLE1# Signal
EM120R-GL&EM160R-GL provide 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 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 modules.
