Hello fellow flyers.

So, a friend just handed down some DYS blheli 20a ESC's.

question: how can I find out what bootloader they have (i suspect simonk) and how to get around flashing them.

It would be nice to flash them trough cleanflight, and from I have read, you can only do that if they have the blheli bootloader, unless things have changed and now we can do both boot loaders through cleanflight...

Hi

If you are not sure what Bootloader you have got on your ESCs, easiest way to check is try to establish 1-wire interface in BLHeliSuite, try both SimonK and BLehli options see which one works. If none of these works, it probably indicates there is no bootloader installed.

Got it going.
Thanks.
