Error message lookup
Type or paste the message your drone's app is showing: DJI and Agras messages, or Betaflight's arming flags for FPV quads. You can also type the beeps your quad makes when it won't arm. You'll get what it means, the likely causes, how to check, and how to fix it — with a confidence rating so you know how much to trust the match.

About this tool. It matches the wording of common messages from DJI's apps, which vary a little between models and app versions — so type what you see as closely as you can. It doesn't read DJI's numeric error codes, because what they mean varies by model and most aren't officially published.
Betaflight arming flags and beep codes come from Betaflight's official documentation. Agras spray-system checks follow DJI Agriculture's calibration guide and repair notes from an Agras dealer.
It covers the most common errors, not every one, and it isn't a substitute for the manufacturer's own support. No error message, just a problem? Try the symptom checker.
