In my quest to try and get the BT-500 adapter working, I’d like to try and put my firmware back to how it shipped from the factory back in June/July of last year. In the intervening time, lots of stuff has changed in the source code, including the layout, and I can’t find instructions for how it used to be done along with the requisite git tags to use to build from.
If anyone can give me an assist with this, I’d be very appreciative.
The built images for the factory firmware are available from the following link:
You want the atmega32u4_firmware.hex file from there. Flash that to your Model01, and you’re back to the firmware it shipped with.
Building the same thing from sources is a bit more involved, but I can walk you through it if you really want to. The precompiled one is easier to work with though.
