Hello,
First of all, sorry for my english (i’am french…)
I Have a problem whith my APM i hope you can help me …
Since this morning , when i connected my LIPO to my quadcopter, i noticed that the 3 LED statut of the APM were OFF… And on my screen for FPV the minimosd told me “Waiting for mavlink heartbeat” …
I disconnect the LIPO and I tried to connect the APM to my computer without success.
I tried to change firmware, tried on another computer, tried differents USB cables, tried to reinstall drivers… But nothing works ! Yesterday everything was OK (no minimosd message, APM connection to computer without any problem, 3 LED working etc). I have done nothing since yesterday with it.
I do a video to show you the problem:
