wiced_bt_gatt_status_t wiced_bt_gatt_server_send_read_multiple_rsp ( uint16_t  conn_id,
wiced_bt_gatt_opcode_t  opcode,
uint16_t  len,
uint8_t *  p_app_rsp_buffer,
wiced_bt_gatt_app_context_t  p_app_ctxt 
)

Server API to respond to read multiple request from the client This API can be used to respond to GATT_REQ_READ_MULTI or GATT_REQ_READ_MULTI_VAR_LENGTH The application receivess a callback on the registered wiced_bt_gatt_cback_t with the wiced_bt_gatt_attribute_request_t::opcode set to GATT_REQ_READ_MULTI or GATT_REQ_READ_MULTI_VAR_LENGTH.

Parameters
[in]conn_id: GATT Connection ID
[in]opcode: The opcode received in the event
[in]len: Actual valid length pointed to by p_app_rsp_buffer
[in]p_app_rsp_buffer: The formatted data response
[in]p_app_ctxt: Application context for p_app_rsp_buffer
Note
The application may free/release/deallocate the p_app_rsp_buffer pointer on receiving a GATT_APP_BUFFER_TRANSMITTED_EVT with wiced_bt_gatt_buffer_transmitted_t::p_app_data = p_app_rsp_buffer and wiced_bt_gatt_buffer_transmitted_t::p_app_ctxt = p_app_ctxt
Returns
wiced_bt_gatt_status_t
wiced_bt_gatt_status_t wiced_bt_gatt_server_send_write_rsp ( uint16_t  conn_id,
wiced_bt_gatt_opcode_t  opcode,
uint16_t  handle 
)

Server API to respond to a write request from the client This API can be used to respond to GATT_REQ_WRITE The application receives a callback on the registered wiced_bt_gatt_cback_t with the wiced_bt_gatt_attribute_request_t::opcode set to GATT_REQ_WRITE or GATT_CMD_WRITE or GATT_CMD_SIGNED_WRITE The command parameters are in wiced_bt_gatt_write_req_t.

Parameters
[in]conn_id: GATT Connection ID
[in]opcode: The opcode received in the event
[in]handle: The handle as received in the request
Returns
wiced_bt_gatt_status_t
uint16_t wiced_bt_gattdb_getAttrUUID16 ( const wiced_gattdb_entry_t *  p_db_entry)

Utility function to return the 16 bit UUID of the database entry in the local database This will return a attribute UUID in the entry.

If the attribute uuid is not 2 bytes. It will return 0x0 which is invalid uuid.

Parameters
[in]p_db_entryDatabase entry for which the UUID is to be returned.
Returns
16 bit UUID value if available, or 0
uint8_t* wiced_bt_gattdb_getAttrValue ( const wiced_gattdb_entry_t *  p_db_entry)

Utility function to return the data of the database entry in the local database.

Parameters
[in]p_db_entryDatabase entry of which the data is to be returned.
Returns
data of the database entry
const wiced_gattdb_entry_t* wiced_bt_gattdb_local_read_data_by_type ( wiced_bt_gatt_discovery_type_t  type,
const wiced_gattdb_entry_t *  p_db_start,
wiced_bt_gatt_discovery_data_t p_disc_data 
)

Utility function to read local registered db by type, by iterating to the next in a loop database entry.

Initially p_db_start is set to NULL, which resets the search to the head of the local database. The database is traversed to locate the next entry which matches the intended type. If an entry is found the data of that entry is written to p_disc_data and the entry in the database is returned. The returned entry is passed in the subsequent call to this function in p_db_start. If an entry is not found the function returns a NULL, which indicates that the entire database has been iterated and the calling loop can end.

Parameters
[in]typeDiscovery type
[in]p_db_startThe database entry to search from. Value of NULL, resets the database pointer to the head
[out]p_disc_datadiscovered data, only valid if the return is not NULL
Returns
wiced_gattdb_entry_t *
wiced_bool_t wiced_bt_is_same_uuid ( const wiced_bt_uuid_t p_left,
const wiced_bt_uuid_t p_right 
)

Utility function to compare UUIDs.

Parameters
[in]p_left: UUID to compare
[in]p_right: UUID to compare
Returns
WICED_TRUE if same, WICED_FALSE otherwise
