Common Issues

Running into issues? Here are solutions to common problems.

⚠️Device not detected during flashing

  • ✓Try a different USB cable (use data cable, not charge-only)
  • ✓Install CH340 or CP210x drivers for your device
  • ✓Hold BOOT button while connecting USB
  • ✓Try a different USB port (USB 2.0 often works better)

⚠️No other nodes visible

  • ✓Make sure you configured the preset for USA/Canada in the app
  • ✓Verify antenna is properly connected before powering on
  • ✓Move to a location with better line of sight
  • ✓Nodes don't auto-discover - you need to add contacts or join channels
  • ✓Check our Discord for current network status

⚠️Cannot connect via Bluetooth

  • ✓Make sure you flashed the Companion BLE firmware
  • ✓Enable Bluetooth on your phone and grant permissions
  • ✓Try restarting both devices
  • ✓Forget the device in Bluetooth settings and re-pair

⚠️GPS not working

  • ✓Not all devices have GPS - check your hardware specs
  • ✓Move outdoors with clear sky view
  • ✓Wait up to 5 minutes for initial GPS lock
  • ✓GPS may not work well indoors or near buildings

⚠️Poor range/connection quality

  • ✓Use a quality external antenna if your device supports it
  • ✓Elevate your device (higher is always better for LoRa)
  • ✓Avoid indoor locations with metal structures
  • ✓Line of sight is critical for LoRa communications
