esc pass-through and general esc problems with latest 4.1

[robert-hoffmann]

Describe the bug Not sure if this is just because of refactorings in the code, but last night i flashed build 1666 on my Matek F405, with tekko 32/F3 (furling esc's), and it seems like there are initialization problems on the esc side (Furling32_Multi_32_62.Hex and Furling32_Multi_32_61.Hex)

The esc's will initialize randomly, and multiple times. Also BLHELI will fail to systematically read the esc's via the pass-through, and when it works will display input frame errors in the results.

Going back to build 1569, fixes the issues.

I haven't tried any other builds to try to narrow down the problem, because i was actually only interested in getting #7907 into my current config

I think you have to flash 32.63 as Dshot has been inverted in meanwhile.

Just did a quick reflash of 4.1 with 32.63 No more weird esc errors, and a quick hover seemed ok.

Will give this a dozen packs this afternoon and see how things go ;-)

Thanks !

Works like a charm, even better than build 1569 ...however seems like some stuff on vtx table has changed, and lua script cannot update the channel anymore via my xlite ^^

Seems like that will be fixed in #8350
