1. Flash the actual image for each half of the split keyboard (e.g `my_board_left.uf2` to the left half, `my_board_right.uf2` to the right half)
After completing these steps, pair the halves of the split keyboard together by resetting them at the same time. Most commonly, this is done by grounding the reset pins
for each of your keyboard's microcontrollers or pressing the reset buttons at the same time.

### Connectivity Issues ###
Some users may experience a poor connection between the keyboard and the host. This might be due to poor quality BLE hardware, a metal enclosure on the keyboard or host, or the distance between them. Increasing the transmit power of the keyboard's BLE radio may reduce the severity of this problem. To do this, set the `CONFIG_BT_CTLR_TX_PWR_PLUS_8` configuration value in the `.conf` file of your user config directory as such:
```
CONFIG_BT_CTLR_TX_PWR_PLUS_8=y
```
For the `nRF52840`, the value `PLUS_8` can be set to any multiple of four between `MINUS_20` and `PLUS_8`. The default value for this config is `0`, but if you are having connection issues it is recommended to set it to `PLUS_8` because the power consumption difference is negligible. For more information on changing the transmit power of your BLE device, please refer to [the Zephyr docs.](https://docs.zephyrproject.org/latest/reference/kconfig/CONFIG_BT_CTLR_TX_PWR_PLUS_8.html)
