3.8.2. DTR Signal
The DTR signal supports sleep control function. Driving it to low level will wake up the module.
3.8.3. W_DISABLE# Signal
EG25-G Mini PCIe provides a W_DISABLE# signal to disable or enable the RF function (not include
GNSS).
W_DISABLE# signal function is disabled by default, and AT+QCFG=“airplanecontrol”,1 can be used to
enable this function. The W_DISABLE# pin is pulled up by default. Driving it to low level will let the module
enter into airplane mode.
AT+CFUN can also be used to control the RF status, and the details are as follows:
