Configuring Bluetooth mesh in nRF Connect SDK

The Bluetooth® mesh support is controlled by CONFIG_BT_MESH, which depends on the following configuration options:

• CONFIG_BT - Enables the Bluetooth subsystem.

• CONFIG_BT_OBSERVER - Enables the Bluetooth Observer role.

• CONFIG_BT_PERIPHERAL - Enables the Bluetooth Peripheral role.

Optional features configuration

Optional features in the Bluetooth mesh stack must be explicitly enabled:

• CONFIG_BT_MESH_RELAY - Enables message relaying.

• CONFIG_BT_MESH_FRIEND - Enables the Friend role.

• CONFIG_BT_MESH_LOW_POWER - Enabels the Low Power role.

• CONFIG_BT_MESH_PROVISIONER - Enables the Provisioner role.

• CONFIG_BT_MESH_GATT_PROXY - Enables the GATT Proxy Server role.

• CONFIG_BT_MESH_PB_GATT - Enables the GATT provisioning bearer.

• CONFIG_BT_MESH_CDB - Enables the Configuration Database subsystem.

The persistent storage of the Bluetooth mesh provisioning and configuration data is enabled by CONFIG_BT_SETTINGS. See the Persistent storage section of Bluetooth Stack Architecture for details.

Mesh models

The nRF Connect SDK Bluetooth mesh model implementations are optional features, and each model has individual Kconfig options that must be explicitly enabled. See Bluetooth mesh models for details.
