LED Patterns

The device has 3 three LEDs (B, G, R = Blue, Green, Red), labeled STATUS: 🔵🟢🔴

  • Patterns during booting/restart:
    • 🔵⚪🔴 B and R on: Device is in Bootloader Mode (not actively running, remove config adapter press reset to leave Bootloader Mode).
    • ⚪🟢⚪ G on for ~2s and off again: Device just booted, either after power on, reset b button or software, or after a hard failure.
    • ⚪⚪🔴 R flashes repeatedly on and off in 1s interval: critical failure during boot (failed to start application).
  • Patterns during normal operation:
    • 🔵⚪⚪ B flashes 1s on and 1s off in loop: building LTE connection to mobile provider. Followed by:
      • ⚪🟢⚪ Short G flash on success.
      • ⚪⚪🔴 Short R flash after connection failed.
    • There are no patterns during normal LoRaWAN operation.
  • Exceptional patterns:
    • 🔵⚪🔴/⚪🟢🔴 Quickly changing between R & B and G & B every 5s in a loop: Modem is in connection restriction mode - keep device on power, will fix itself after 30min.
