This is a small journey on how I reverse engineered the MagicForce 68 keyboard and tried to add bluetooth functionality to it. It’s a small keyboard (68 keys, 65%) and is USB-only (it’s not the smart model). It has a controller that I can’t flash with a custom firmware, so I had to hook wires on it. The Hardware The first step in determining what I was against, was to at least partially disassemble the keyboard.

First of all, lets flash Adafruit’s NRF52 bootloader for easier future flashing My J-Link was “Broken. No longer used” - or so the JLink tools said (AKA bought from e-bay). So I had to go to openocd). Connect the J-Link (or any SWD capable debugger supported by openocd - even an FT232 breakout will do) to the target - I have a Bluefruit by Adafruit. git clone https://github.com/adafruit/Adafruit_nRF52_Bootloader cd Adafruit_nRF52_Bootloader make BOARD=feather_nrf52832 all FIRMWARE=lib/softdevice/s132_nrf52_6.
