## Troubleshooting
### 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/kconfig.html#CONFIG_BT_CTLR_TX_PWR)
### Using bluetooth output with USB power
If you want to test bluetooth output on your keyboard and are powering it through the USB connection rather than a battery, you will be able to pair with a host device but may not see keystrokes sent. In this case you need to use the [output selection behavior](../docs/behaviors/outputs.md) to prefer sending keystrokes over bluetooth rather than USB. This might be necessary even if you are not powering from a device capable of receiving USB inputs, such as a USB charger.

### File Transfer Error

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.
