15 days ago@davidrevoy The Nordic chip is quite popular in the maker community. It is just the Bluetooth soft core that is closed. I did some analysis of the device and the firmware is not even locked and can be downloaded. A new one could be written too, but it is a lot of work to implement the HID stack over Bluetooth. So at the end I decided to write a user space remapping program that utilizes the same raw mode the original application provided by XP pen uses. https://github.com/MarSik/kymars-xppen-act05
