I was tweaking my quad trough GCS when mavlink connection was suddenly lost.
Ground Unit couldn’t see Air Unit anymore. Tried powering off/on again, nothing.
Air Unit is now totally unresponsive, but seems it’s a singer now…
It emmitts an odd noise since this happend.
Video here:
Air Unit is powered with 11v bec.
It never flied yet, I still have some setup to do.
Even if it’s faulty, any idea what could happened ? I’m a bit worried now it happen again with another unit in flight.
Unit was a bit hot but nothing anormal it seems
The noise I get here looks like a power issue ( blown capacitor on the regulator perhaps? )
I have triple checked my wiring with a multimeter everything is correct ( it was working correctly before earing this noise and communication shutdown after 5mn. )
So I’ve plugued it on USB ( & powered by 11v bec ) , It mounts the SD drive and then unmount it 1 sec later, then mount it again, etc.
Still the strange singing sound.
Can you try to update the firmware again on the air unit? Just in case it was software problem.
If it was hardware problem, the updater should be not able to detect the unit at all.
