W_Disable - Quectel RG255C-GL Hardware Design

4.5.1. RI
The RI signal can be used to wake up the host. When a URC returns, there will be the following behaviors
on the RI pin after executing AT+QCFG="risignaltype","physical".

4.5.2. W_DISABLE#

The module provides a W_DISABLE# signal to disable or enable the RF function (excluding GNSS). The
W_DISABLE# pin is pulled up by default. Its control function for airplane mode is disabled by default, and
AT+QCFG="airplanecontrol",1 can be used to enable the function. Driving the pin low after its control
function for airplane mode is enabled by AT command, which can make the module enter the airplane
mode.
