Flash the firmware to the keyboard:

1. Plug in the left kb to the laptop.
2. Double press the reset button.
3. Download firmware from the latest workflow of the Github actions: example.
4. Unzip the firmware.zip.
5. cp firmware/splitkb_aurora_sweep_left-nice_nano_v2-zmk.uf2 /run/media/$USER/NICENANO Repeat the operation for the right kb.

Pairing keyboard with the laptop:

1. Turn on the left kb: pwr button UP, turn on right kb: pwr button DOWN (don't trust the pwr mark on the pcb).
2. Select bluetooth channel on splitkb: ht_har B + bt_sel n
3. Setup bluetooth controller:

bluetoothctl            # open the cli bluetooth manager
  power on              # turn the controller (laptop) on
  pairable on           # enable the controller for pairing
  scan on               # scan devices
  pair MAC_ADDR         # pair the controller with the splitkb
  connect MAC_ADDR      # connect the controller with the splitkb
  scan off
  pairable off

The left kb is the master and the right one is the slave. The right is connected to the left, which is connected to the laptop.

Issue with azerty system

Only qwerty laptops are supported. For the azerty's, that can be changed in some UEFI or from the window manager.

Example for Hyrpland:

input {
  kb_layout = us
  ...
}
