Hi, i am working on understanding and reproducing the MCU's NFC functionality (mart1nro/joycontrol#89) and in the process wrote a wireshark plugin to dissect the Bluetooth communication between Joycon and switch.
I know that something similar already exists for traffic captured via usb implemented in LUA but i couldn't get the LUA API to do as I wanted, so this is implemented in C (also no
elifchains).If you want I can also supply a compiled version for ubuntu x64 that should be just as simple to use as the LUA one.
Currently the following is dissected:
and these only mark the appropiate fields:
Beyond that the main thing obviously missing is marking of known constants as "expected".
The traffic this dissects is captured by using a PC running wireshark as proxy between the Switch and a Joycon (Pro Controller works, but overloads my laptops's bluetooth controller)
