Description
Low Level (Light ON)
Registered on network successfully
High-impedance (Light OFF)
 No network coverage or not registered
 W_DISABLE# signal is at low level. (Disable the RF)
 AT+CFUN=0, AT+CFUN=4
3.8.6. WAKE# Signal
The WAKE# signal is an open collector signal which is similar to RI signal, but a host pull-up resistor and
AT+QCFG="risignaltype","physical" command are required. When a URC returns, a 120ms low level
pulse will be outputted. The state of WAKE# signal is shown as below.
