Detailed Description

Local Bluetooth LE controller features and capabilities.

This struct provides details about the Bluetooth LE controller's supported features, states, and various other capabilities. It includes information on ACL and ISO data packet lengths, the controller's resolving list size, and the maximum advertising data length. This information can be obtained after enabling the Bluetooth stack with bt_enable function.

Refer to the Bluetooth Core Specification, Volume 6, Part B and Volume 4, Part E for detailed sections about each field's significance and values.

Field Documentation

acl_mtu

uint16_t bt_le_local_features::acl_mtu

ACL data packet length.

This represents the maximum ACL HCI Data packet which can be sent from the Host to the Controller. The Host may support L2CAP and ATT MTUs larger than this value. See Bluetooth Core Specification, Vol 6, Part E, Section 7.8.2.

acl_pkts

uint8_t bt_le_local_features::acl_pkts

Total number of ACL data packets.

features

uint8_t bt_le_local_features::features[8]

Local LE controller supported features.

Refer to BT_LE_FEAT_BIT_* for values. Refer to the BT_FEAT_LE_* macros for value comparionson. See Bluetooth Core Specification, Vol 6, Part B, Section 4.6.

iso_mtu

uint16_t bt_le_local_features::iso_mtu

ISO data packet length.

This represents the maximum ISO HCI Data packet which can be sent from the Host to the Controller. ISO SDUs above this size can be fragmented assuming that the number of bt_le_local_features::iso_pkts support the maximum size.

iso_pkts

uint8_t bt_le_local_features::iso_pkts

Total number of ISO data packets.

max_adv_data_len

uint16_t bt_le_local_features::max_adv_data_len

Maximum advertising data length.

Note

The maximum advertising data length also depends on advertising type.

See Bluetooth Core Specification, Vol 6, Part E, Section 7.8.57.

rl_size

uint8_t bt_le_local_features::rl_size

Maximum size of the controller resolving list.

See Bluetooth Core Specification, Vol 6, Part E, Section 7.8.41.

states

uint64_t bt_le_local_features::states

Local LE controller supported states.

Refer to BT_LE_STATES_* for values. See Bluetooth Core Specification 6.0, Vol 4, Part E, Section 7.8.27
