Typedef Documentation

typedef uint16_t bt_sdp_attribute_id_t

Define the attribute ID.

Attribute is identified by an attribute ID. This type includes most (but not all) of the possible attributes available on a Bluetooth device.

Upper layer services may use these attributes or define their own. In this case, the service must define attributes with IDs between 0x0200 and 0xFFFF.Define the type of attribute ID.

typedef uint8_t bt_sdp_data_element_size_t

Define the type of data element size.

typedef uint8_t bt_sdp_data_element_type_t

Data elements begin with a single byte that contains both type and size information.

To create the first byte of a data element, bitwise "or" the bt_sdp_data_element_type_t and bt_sdp_data_element_size_t values into a single byte.

For example, a standard 16 bits unsigned integer with a value of 0x57 could be encoded as follows:

uint8_t val[3] = { BT_SDP_DATA_ELEMENT_TYPE_UINT | BT_SDP_DATA_ELEMENT_SIZE_2BYTE, 0x00, 0x57};

The text string "hello" could be encoded as follows:

uint8_t str[7] = { BT_SDP_DATA_ELEMENT_TYPE_TEXT | BT_SDP_DATA_ELEMENT_SIZE_ADDITIONAL_8BIT, 0x05, 'h','e','l','l','o'};Define the type of data element.

typedef uint16_t bt_sdp_protocol_uuid_t

The UUIDs associated with protocols.

Any number of these UUIDs may be present in the BT_SDP_ATTRIBUTE_ID_SERVICE_CLASS_ID_LIST attribute of a service record and may appear in the BT_SDP_ATTRIBUTE_ID_BT_PROFILE_DESC_LIST ID.Defines the type of protocol ID.

typedef uint16_t bt_sdp_service_class_id_t

The UUIDs associated with a specific service and profile.

Any number of these UUIDs may be present in the BT_SDP_ATTRIBUTE_ID_SERVICE_CLASS_ID_LIST attribute of a service record and may appear in the BT_SDP_ATTRIBUTE_ID_BT_PROFILE_DESC_LIST ID. Defines the type of service class ID.
