3.7.2. W_DISABLE#
W_DISABLE# enables/disables the RF function (excluding GNSS). It is pulled up by default, and driving it
low makes the module enter airplane mode.
The pin function is disabled by default, and AT+QCFG="airplanecontrol",1 can be used to enable this
function.
Table 11: Airplane Mode Control (Hardware Method)
The RF function can also be enabled/disabled with AT+CFUN=<fun>, and the details are listed below.

3.7.3. PERST#
PERST# forces a hardware reset on the module. The module can be reset by driving PERST# low for
2–3.8 s and then releasing it. The reset timing is illustrated in the following figure.
