LEDs and buttons
The M2MBoxPro user interface consists of 6 connection LEDs, 3 application LEDs and two user buttons.
The two user buttons are connected to Q26 GPIO 1 and GPIO 2 signals, and are debounced by hardware.
There are two additional buttons, one that will instantly cause a reset of the processor (to use only in case
of software crash), and a ON/OFF button whose function is described in the Power Source section of this
document).
The three application LEDs are driven by the openAT application or by AT commands: GPIO32 drives the
Status LED, GPIO33 drives the A1 LED and GPIO34 drives the A2 LED.
The connection LEDs are driven by hardware and give insight about the M2MBoxPro interfaces status:
–
Power LED: is green when the M2MBoxPro is powered by the mains, and yellow if it is powered by the
battery
–
GSM LED: is solid if the M2MBoxPro can’t connect to the cellular network, and is blinking otherwise
–
LAN, Serial1, Serial2 and I²C LEDs are flashing when there is activity on their respective interface.
