0 pins division by zero

[barsikus007]

When I setup rescue app I specified 0 pins (cause I have no leds at all, I want to use it as BLEproxy rn)

Now I have bootloop with this

repeating at serial

this is stacktrace decoding

and can you provide me any way to reset this, please

Ok, I see this is indeed a bug. I will fix this bug by deactivating lights if pixel count is set to zero, but for the moment I guess you could work around by simply setting pixel count > 0. Without a LED strip connected, the code will still work.

I can't change settings due to bootloop

btw I changed code to reset config and now all works properly

[thankthemaker]

Ok, glad you found a solution.You could also use the webinstaller and erase flash during installation. https://rescue.thank-the-maker.org/install
