Impossible to say without some details of your setup and posting a log file.

Is it a low battery signal?

with pleasure a logs but look at my last post i can’t get a log ?

there is no list of the bip errors ? so what make a signal that can’t be understanding by the user ?

i will try with a full battery tomorrow and i write the result ok

explain to me how have logs without terminal and with error :

Error:System.TimeoutException: Timeout on read - GetLogEntry

à MissionPlanner.Log.LogDownloadMavLink.b__12_0() dans C:\Users\michael\Source\Repos\MissionPlanner\Log\LogDownloadMavLink.cs:ligne 90

The logs are not done through terminal anymore but via Mavlink in the Flight Data screen of Mission Planner.

Yes i know i know… no terminal …help me to solved the problem… with the other method ( via Mavlink in the Flight Data screen of Mission Planner) i have error

Error:System.TimeoutException: Timeout on read - GetLogEntry
