4.9.1. W_DISABLE#
⚫ The module provides a W_DISABLE# pin to enable or disable airplane mode through hardware
operation. W_DISABLE# is pulled up by default, and driving it low will set the module to airplane
mode.
⚫ The RF function can also be enabled or disabled through software AT commands (when <fun> = 0 or
4, the RF function will be disabled. When <fun> = 1, if W_DISABLE# is at high level, then RF
function will be enabled; if it is at low level, then RF function will still be disabled.
