N# O 3G Cellular STAT
LED Output 1.8V Command to enable
LED function,
AT#GPIO=1,0,2. This pin
needs an external
transistor to drive an
external LED.
Therefore, status
indicated is reversed
with respect to the pin
status:
Permanently off =
Device off
Fast blinking (Period 1s,
Ton 0.5s) = Net search /
Not registered / turning
off
Slow blinking (Period
3s, Ton 0.3s) =
Registered full service
Permanently on = a
voice call is active
