KBTools Manual or Source Code

Anyone have information on KBTools, app used to configure KBDfans’ KBD6X RGB v2? I prefer QMK but the PCB doesn’t seem to respond to any of the usual QMK reset key combos and lacks the reset jumper present in the v1 of KBD6X PCB.

Any kind of technical information like protocol or pointers to source code would be appreciated. It seems to work like VIA Config and I’m aware of https://github.com/olivia/via-config but I’m not sure if they use the same protocol or not.
