Typedefs

void() wiced_bt_a2d_find_cback (wiced_bool_t found, wiced_bt_a2d_service_t *p_service)

A2D Find Service Discovery callback.

Callback for A2D Find Service Discovery Records Registered using wiced_bt_a2d_find_service() The callback function will be executed when service discovery is complete.

note

This is the callback to notify the result of the SDP discovery process

Parameters

  • found – : Record found status

  • p_service – : Contains result of SDP discovery process

Returns

Status of event handling

Functions

uint8_t wiced_bt_a2d_bits_set(uint8_t mask)

Check the number of bits set in a given mask (used to parse stream configuration masks)

Parameters

mask – [in] : mask to check

Returns

A2D_SET_BIT

wiced_bt_a2d_status_t wiced_bt_a2d_find_service(uint16_t service_uuid, wiced_bt_device_address_t bd_addr, wiced_bt_a2d_sdp_db_params_t *p_db, wiced_bt_a2d_find_cback *p_cback)

Performs Service Discovery and fetches SRC/SINK SDP Record Info.

Information is returned for the first service record found on the server that matches the service UUID.There can only be one outstanding call to wiced_bt_a2d_find_service() at a time; the application must wait for the callback before it makes another call to the function.

Parameters

  • service_uuid – [in] : Indicates SRC or SNK.

  • bd_addr – [in] : BD address of the peer device.

  • p_db – [in] : Pointer to the information to initialize the discovery database.

  • p_cback – [in] : Pointer to the wiced_bt_a2d_find_service() callback function.

Returns
