The
LED_WWAN_N signal (PIN No: 42, Status Indication PIN) is the signal indicating the current working status of the module, which
is generated by the module. The LED indicator need to be equipped on the system side for this feature, and the LED indicator is ON
when this signal generates the low power level. Table below illustrates the indicator status, and Figure below illustrates the
reference circuit design of LED_WWAN_N signal.
