Status LEDs (one yellow, one red)
The red and yellow Status LEDs are under control of GPIO1 and GPIO2 of the LE910 EU1 module inside
the Terminal. They can be controlled via AT commands. The default status of these two LEDs is off. The
following commands must be used to initialize and to configure the GPIOs to control the two LEDs:
Switching on red LED
at#gpio=2,1,1
Switching off red LED
at#gpio=2,0,1
Switching on yellow LED
at#gpio=3,1,1
Switching off yellow LED
at#gpio=3,0,1
These LEDs can be controlled e.g. by an external microcontroller via AT commands issued to the
terminal via the RS232 interface. They can be used to signal any useful status of the external
application such as:
▪
error indication
▪
status of communication (LTE, GPRS, SMS, CSD, etc.)
▪
status of network (to simulate network LED)
▪
quality of service
