Runtime Configuration

The runtime configuration API allows applications to change their runtime configuration directly, without going through the Configuration models.

Bluetooth Mesh nodes should generally be configured by a central network configurator device with a Configuration Client model. Each mesh node instantiates a Configuration Server model that the Configuration Client can communicate with to change the node configuration. In some cases, the mesh node can’t rely on the Configuration Client to detect or determine local constraints, such as low battery power or changes in topology. For these scenarios, this API can be used to change the configuration locally.

Note

Runtime configuration changes before the node is provisioned will not be stored in the persistent storage.

Functions

void bt_mesh_beacon_set(bool beacon)

Enable or disable sending of the Secure Network Beacon.

Parameters:

• beacon – New Secure Network Beacon state.

bool bt_mesh_beacon_enabled(void)

Get the current Secure Network Beacon state.

Returns:

Whether the Secure Network Beacon feature is enabled.

int bt_mesh_priv_beacon_set(enum bt_mesh_feat_state priv_beacon)

Enable or disable sending of the Mesh Private beacon.

Support for the Private beacon state must be enabled with CONFIG_BT_MESH_PRIV_BEACONS.

Parameters:

• priv_beacon – New Mesh Private beacon state. Must be one of BT_MESH_FEATURE_ENABLED and BT_MESH_FEATURE_DISABLED.

Return values:

• 0 – Successfully changed the Mesh Private beacon feature state.

• -ENOTSUP – The Mesh Private beacon feature is not supported.

• -EINVAL – Invalid parameter.

• -EALREADY – Already in the given state.

enum bt_mesh_feat_state bt_mesh_priv_beacon_get(void)

Get the current Mesh Private beacon state.

Returns:

The Mesh Private beacon feature state.

void bt_mesh_priv_beacon_update_interval_set(uint8_t interval)

Set the current Mesh Private beacon update interval.

The Mesh Private beacon’s randomization value is updated regularly to maintain the node’s privacy. The update interval controls how often the beacon is updated, in 10 second increments.

Parameters:

• interval – Private beacon update interval in 10 second steps, or 0 to update on every beacon transmission.

uint8_t bt_mesh_priv_beacon_update_interval_get(void)

Get the current Mesh Private beacon update interval.

The Mesh Private beacon’s randomization value is updated regularly to maintain the node’s privacy. The update interval controls how often the beacon is updated, in 10 second increments.

Returns:

The Private beacon update interval in 10 second steps, or 0 if the beacon is updated every time it’s transmitted.

int bt_mesh_default_ttl_set(uint8_t default_ttl)

Set the default TTL value.

The default TTL value is used when no explicit TTL value is set. Models will use the default TTL value when bt_mesh_msg_ctx::send_ttl is BT_MESH_TTL_DEFAULT.

Parameters:

• default_ttl – The new default TTL value. Valid values are 0x00 and 0x02 to BT_MESH_TTL_MAX.

Return values:

• 0 – Successfully set the default TTL value.

• -EINVAL – Invalid TTL value.

uint8_t bt_mesh_default_ttl_get(void)

Get the current default TTL value.

Returns:

The current default TTL value.

int bt_mesh_od_priv_proxy_get(void)

Get the current Mesh On-Demand Private Proxy state.

Return values:

• 0 – or positive value represents On-Demand Private Proxy feature state

• -ENOTSUP – The On-Demand Private Proxy feature is not supported.

int bt_mesh_od_priv_proxy_set(uint8_t on_demand_proxy)

Set state of Mesh On-Demand Private Proxy.

Support for the On-Demand Private Proxy state must be enabled with BT_MESH_OD_PRIV_PROXY_SRV.

Parameters:

• on_demand_proxy – New Mesh On-Demand Private Proxy state. Value of 0x00 means that advertising with Private Network Identity cannot be enabled on demand. Values in range 0x01 - 0xFF set interval of this advertising after valid Solicitation PDU is received or client disconnects.

Return values:

• 0 – Successfully changed the Mesh On-Demand Private Proxy feature state.

• -ENOTSUP – The On-Demand Private Proxy feature is not supported.

• -EINVAL – Invalid parameter.

• -EALREADY – Already in the given state.

void bt_mesh_net_transmit_set(uint8_t xmit)

Set the Network Transmit parameters.

The Network Transmit parameters determine the parameters local messages are transmitted with.

See also

BT_MESH_TRANSMIT

Parameters:

• xmit – New Network Transmit parameters. Use BT_MESH_TRANSMIT for encoding.

uint8_t bt_mesh_net_transmit_get(void)

Get the current Network Transmit parameters.

The BT_MESH_TRANSMIT_COUNT and BT_MESH_TRANSMIT_INT macros can be used to decode the Network Transmit parameters.

Returns:

The current Network Transmit parameters.

int bt_mesh_relay_set(enum bt_mesh_feat_state relay, uint8_t xmit)

Configure the Relay feature.

Enable or disable the Relay feature, and configure the parameters to transmit relayed messages with.

Support for the Relay feature must be enabled through the CONFIG_BT_MESH_RELAY configuration option.

See also

BT_MESH_TRANSMIT

Parameters:

• relay – New Relay feature state. Must be one of BT_MESH_FEATURE_ENABLED and BT_MESH_FEATURE_DISABLED.
