### Split keyboards
Following split keyboard settings are defined in [zmk/app/src/split/Kconfig](https://github.com/zmkfirmware/zmk/blob/main/app/src/split/Kconfig) (generic) and [zmk/app/src/split/Kconfig](https://github.com/zmkfirmware/zmk/blob/main/app/src/split/bluetooth/Kconfig) (bluetooth).
| `CONFIG_BT` | bool | Enable Bluetooth support | |
| `CONFIG_BT_MAX_CONN` | int | Maximum number of simultaneous Bluetooth connections | 5 |
| `CONFIG_BT_MAX_PAIRED` | int | Maximum number of paired Bluetooth devices | 5 |
| `CONFIG_ZMK_BLE` | bool | Enable ZMK as a Bluetooth keyboard | |
| `CONFIG_ZMK_BLE_CLEAR_BONDS_ON_START` | bool | Clears all bond information from the keyboard on startup | n |
| `CONFIG_ZMK_BLE_CONSUMER_REPORT_QUEUE_SIZE` | int | Max number of consumer HID reports to queue for sending over BLE | 5 |
| `CONFIG_ZMK_BLE_KEYBOARD_REPORT_QUEUE_SIZE` | int | Max number of keyboard HID reports to queue for sending over BLE | 20 |
| `CONFIG_ZMK_BLE_INIT_PRIORITY` | int | BLE init priority | 50 |
| `CONFIG_ZMK_BLE_THREAD_PRIORITY` | int | Priority of the BLE notify thread | 5 |
| `CONFIG_ZMK_BLE_THREAD_STACK_SIZE` | int | Stack size of the BLE notify thread | 512 |
| `CONFIG_ZMK_BLE_PASSKEY_ENTRY` | bool | Experimental: require typing passkey from host to pair BLE connection | n |

| `CONFIG_ZMK_SPLIT_BLE` | bool | Use BLE to communicate between split keyboard halves | y |
| `CONFIG_ZMK_SPLIT_BLE_ROLE_CENTRAL` | bool | `y` for central device, `n` for peripheral | |
| `CONFIG_ZMK_SPLIT_ROLE_CENTRAL` | bool | `y` for central device, `n` for peripheral | |
| `CONFIG_ZMK_SPLIT_BLE_CENTRAL_POSITION_QUEUE_SIZE` | int | Max number of key state events to queue when received from peripherals | 5 |
| `CONFIG_ZMK_BLE_SPLIT_CENTRAL_SPLIT_RUN_STACK_SIZE` | int | Stack size of the BLE split central write thread | 512 |
| `CONFIG_ZMK_BLE_SPLIT_CENTRAL_SPLIT_RUN_QUEUE_SIZE` | int | Max number of behavior run events to queue to send to the peripheral(s) | 5 |
| `CONFIG_ZMK_SPLIT_BLE_PERIPHERAL_STACK_SIZE` | int | Stack size of the BLE split peripheral notify thread | 650 |
| `CONFIG_ZMK_SPLIT_BLE_PERIPHERAL_PRIORITY` | int | Priority of the BLE split peripheral notify thread | 5 |
| `CONFIG_ZMK_SPLIT_BLE_PERIPHERAL_POSITION_QUEUE_SIZE` | int | Max number of key state events to queue to send to the central | 10 |
Note that `CONFIG_BT_MAX_CONN` and `CONFIG_BT_MAX_PAIRED` should be set to the same value. On a split keyboard they should only be set for the central and must be set to one greater than the desired number of bluetooth profiles.
For behaviors that do not require central locality, the following options for updating `app/CmakeLists.txt` also exist:
- Behavior applies to unibody, or central or peripheral half of keyboard: place `target_sources(app PRIVATE <behavior_name>.c)` line _before_`if ((NOT CONFIG_ZMK_SPLIT) OR CONFIG_ZMK_SPLIT_ROLE_CENTRAL)`
- Behavior applies to _only_ central half of split keyboard: place `target_sources(app PRIVATE <behavior_name>.c)` after `if (CONFIG_ZMK_SPLIT_BLE AND CONFIG_ZMK_SPLIT_ROLE_CENTRAL)`
- Behavior applies to _only_ peripheral half of split keyboard: place `target_sources(app PRIVATE <behavior_name>.c)` after `if (CONFIG_ZMK_SPLIT_BLE AND (NOT CONFIG_ZMK_SPLIT_ROLE_CENTRAL))`
- Behavior applies to _only_ central half of split keyboard: place `target_sources(app PRIVATE <behavior_name>.c)` after `if (CONFIG_ZMK_SPLIT AND CONFIG_ZMK_SPLIT_ROLE_CENTRAL)`
- Behavior applies to _only_ peripheral half of split keyboard: place `target_sources(app PRIVATE <behavior_name>.c)` after `if (CONFIG_ZMK_SPLIT AND (NOT CONFIG_ZMK_SPLIT_ROLE_CENTRAL))`
- Behavior requires certain condition in a keyboard's `.conf` file to be met: use `target_sources_ifdef(CONFIG_<Configuration Requirement> app PRIVATE <behavior_name>.c)` instead of `target_sources(<behavior_name>.c)`
