@Alex-Kushleyev
Thanks for the quick response.
I was able to upload firmware version 36, but had issues getting the ESC set to the right baud rate, usingvoxl-esc-upload-params.py. Even though I was giving it 250,000 as the baud rate, it seemed to be stuck at 57600, which may have been a hint that the params were not loading well (after further reading in the forums and modalai documentation).
However, now I cannot even communicate with the ESC.
Here is what I get when I try thevoxl-esc-scan.pyscript:
Could I have bricked the ESC...?
Any idea how I might go about reviving it?
Nothing (uplading firmware or parameter or scanning) seems to work at this point.
Thanks much!@jenyeom ,
As i just mentioned above, i will repeat again
use latest voxl-esc tools from dev branch : https://gitlab.com/voxl-public/voxl-sdk/utilities/voxl-esc/-/tree/dev/voxl-esc-tools
You should recover the ESC to the latest state and then if you want to go back to older firmware and params, i can tell you how to do it properly.

Once you recover to the newest firmware, before going to the old firmware, i would suggest that we figure out if you used wrong ESC params in the recent tests. So if you had old params, did you upload them after the ESC firmware was updated to version 39?

Also, if you are using very old SDK on VOXL2, the uart bridge may not be working 100% properly.
When in doubt, the best thing to do is to connect to the ESC using a serial to usb adapter going directly to a Linux PC (and run
voxl-esctools on the PC). do you have that available?
