I FINALLY, FINALLY managed to finish the Pybricks firmware-fork in order to upgrade limited storage size of 512 bytes to 8 kilobytes. This allows longer programs to be stored on the flash without needing a computer attached. I also fixed some annoying problems with btstack, which is apparently a seperate github thing, or so I thought? I’ll find what the problem actually was. Fixing it was mostly time consuming trial-and-error.
