CUSTOM AT COMMANDS
107 AT Commands for EV-DO-EV3 Modems
Parameters and Values
<mode> Defines how the STAT_LED GPIO is handled.
0 GPIO tied low.
1 GPIO tied high.
2 GPIO and duration are handled by Module Software. Default: 2.
3 GPIO is turned on and off alternatively, with period defined by the sum
<on_duration> + <off_duration>.
<on_duration> Duration of period in which STAT_LED GPIO is tied high while <mode>=3.
1-100 In tenth of seconds. Default: 10.
<off_duration> Duration of period in which STAT_LED GPIO is tied low while <mode>=3.
1-100 In tenth of seconds. Default: 10.
Notes
 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 Device turned off.
Fast Blinking Network search, not registered, or turning off.
Slow Blinking Registered full service.
On Active call.
