Interesting! This sounds like something fun to play with. Do I need a devkit to mess with this code or can I do it safely over bluetooth without bricking my Banglejs2?
Bluetooth is slow so updating firmware over it gets old pretty quickly but yes it should be mostly safe, there is a watchdog and bootloader so it is not that easy to brick it but it can be done. Better is to use some SWD debug dongle with the charging cable and usb female cable adapter (just cut some old cable with usb female on it). These things are < US$2 on aliexpress (search for daplink) or you can make almost anything into such dongle (like raspberry pico, blue pill board). Also STLINK V2 clones (like this one https://aliexpress.com/item/1005001621626894.html - $1.60 including shipping for me) work - either as is or reflashed with daplink firmware. I have tons of them so when I need it I often take another one instead of disconnecting it from something :-)
