Kconfig
| Option | Type | Description | Default |
|---|---|---|---|
CONFIG_ZMK_BLE_EXPERIMENTAL_CONN | bool | Enables a combination of settings that are planned to be default in future versions of ZMK to improve connection stability. Currently this only disables 2M PHY support. | n |
CONFIG_ZMK_BLE_EXPERIMENTAL_SEC | bool | Enables a combination of settings that are planned to be officially supported in the future. This includes enabling BT Secure Connection passkey entry, and allows overwrite of keys from previously paired hosts. | n |
CONFIG_ZMK_BLE_EXPERIMENTAL_FEATURES | bool | Aggregate config that enables both CONFIG_ZMK_BLE_EXPERIMENTAL_CONN and CONFIG_ZMK_BLE_EXPERIMENTAL_SEC. | n |
CONFIG_ZMK_BLE_PASSKEY_ENTRY | bool | Enable passkey entry during pairing for enhanced security. (Note: After enabling this, you will need to re-pair all previously paired hosts.) | n |
CONFIG_BT_GATT_ENFORCE_SUBSCRIPTION | bool | Low level setting for GATT subscriptions. Set to n to work around an annoying Windows bug with battery notifications. | y |
