I tried update the software trough bluetooth.
Somewhere past 90% it just died. I dont mean the bluetooth signal, but the whole charger.
I attempted om a second one thinking it was just a bad timing for it to die, but the second one died just the same way.
They are feed 230VAC and I tried power it up and down several times by removing both supply and the battery cables. The charger never powers up again.
I guess the power LED is controlled by a microcontroller and this one never come up again caused by full memory or something.
It dont charge as we can see the battery voltage slowly drooping.
Anyone with deep knowledge about this?
Update from 3.00 to 3.21
