1. Take this code which is for a Arduino with nrf52840 [login to view URL] and make it work on a wioTerminal [login to view URL] - the. Ingest hurdle is converting things like MAC address changing to functions of the RTL8720DN chipset (BLE)
2. Improve on the code. Do use the sd card of the wioTerminal to store config and data that we are using the non volatile memory of the nrf board. Plus create a gui to show : a) what mode the device is in b) what device it’s currently connected to and a way of changing between mouse / keyboard mode - and change which device it’s connected to.
