1. Dynamic BLE roles let a device switch between central and peripheral roles at runtime. For example, this allows switching between using a BLE dongle and connecting directly to a host over BLE without reflashing the device. Lokey supports this at runtime, while in ZMK the role is fixed at compile time. ↩︎

2. Lokey currently only supports split keyboards where the halves communicate over BLE. Serial communication between halves is planned. ↩︎

3. QMK can be remapped at runtime with Via/Vial ↩︎

4. ZMK can be remapped at runtime with ZMK Studio ↩︎
