3.9.4.3.11.3. WWAN_LED#*
The WWAN_LED# signal is used to indicate RF status of the module, and its sink current is up to 10 mA.
In order tTo reduce current consumption of the LED, a current-limited resistor must be placed in series
with the LED, as illustrated in the figure below. The LED is ON when the WWAN_LED# signal is at low
level.
