<on_duration>
1-100
<off_duration>
1-100
Defines how the STAT_LED GPIO is handled.
GPIO tied low.
GPIO tied high.
GPIO and duration are handled by Module Software. Default: 2.
GPIO is turned on and off alternatively, with period defined by the sum
<on_duration> + <off_duration>.
Duration of period in which STAT_LED GPIO is tied high while <mode>=3.
In tenth of seconds. Default: 10.
Duration of period in which STAT_LED GPIO is tied low while <mode>=3.
In tenth of seconds. Default: 10.

Values are saved in non-volatile memory by command #SLEDSAV.
At module boot the STAT_LED GPIO is always tied high and holds this value until the first non-volatile
memory reading.
To have STAT_LED operative, the first time enter AT#GPIO=1,0,2 setting the GPIO1 as alternate function.
Set AT#GPIO=1,0,2 to enable LED on the EV3.
When GPIO_1 is set to <dir> value of 2, the Module Software control the Stat_LED as followings:
Off
Fast Blinking
Slow Blinking
On
Device turned off.
Network search, not registered, or turning off.
Registered full service.
Active call.
