After powering on the tracker you can observe the following indications in this order:
(1) 0. – 10. s: flashing in 1s interval – bootloader awaits new firmware upload.
(2) 11.-13. s: LED ON for approximately 2 seconds – initialisation of serial lines (blu GPS),
radio unit, barometric sensor, SD card (if inserted) and system services.
(3) 14.+ s: two medium-short flashes per second – awaiting GPS fix.
(4) very short flashes – radio traffic– regularly every second (radio TX), or in random intervals
(radio RX).
