Detailed Description

iAP2 library of the AIROC BTSDK provides a simple method for an application to integrate iAP2 functionality.

A single External Accessory session is supported in the current version. Application just needs to call API to connect/disconnect and send data. Library in turn indicates status of the connection and passes to the application received data.

Typedef Documentation

typedef void(* wiced_bt_iap2_connection_down_callback_t)(uint16_t handle)

Function wiced_bt_iap2_connection_down_callback.

Connection Down callback indicates that an active External Accessory session has been terminated.

Parameters

[in] handle : Handle that identifies the external accessory session

Returns: Nothing

typedef void(* wiced_bt_iap2_connection_failed_callback_t)(uint8_t err_code)

Function wiced_bt_iap2_connection_failed_callback.

Connection failed callback indicates to the application that the library failed to establish RFCOMM connection with the peer device after connection was requested by the wiced_bt_iap2_connect call.

Returns: Nothing

typedef void(* wiced_bt_iap2_connection_up_callback_t)(uint16_t handle, uint8_t *bd_addr)

Function wiced_bt_iap2_connection_up_callback.

Application must implement connection up callback to be called by the library. The callback indicates to the application that External Accessory session with a specified device has been successfully established. This can be a result of the wiced_bt_iap2_connect requested by the application, or due to an iOS device establishing connection from its side.

Parameters

[in]	handle	: Handle that identifies the external accessory session
[in]	bd_addr	: Bluetooth Device address of the connected iOS device.

Returns: Nothing

typedef wiced_bool_t(* wiced_bt_iap2_rx_data_callback_t)(uint16_t handle, uint8_t *data, uint32_t dataLen)

Function wiced_bt_iap2_rx_data_callback.

Rx Data callback passed to the application data received over the External Accessory session. The first 2 octets of the data have the handle of the session in the big endian format.

Parameters

[in]	handle	: Handle that identifies the external accessory session
[in]	p_data	: Pointer to buffer with data to send. The first 2 octets of the p_data contain the handle passed to the application in the wiced_bt_iap2_connection_up_callback in the big endian format.
[in]	len	: Length of the data + handle

Returns: Nothing

typedef void(* wiced_bt_iap2_service_not_found_callback_t)(void)

Function wiced_bt_iap2_service_not_found_callback.

Service not found callback indicates wiced_bt_iap2_connect call requested to establish connection to a device which is currently not present, or which is not running IAP2 service.

Returns: Nothing

typedef void(* wiced_bt_iap2_tx_complete_callback_t)(uint16_t handle, wiced_result_t result)

Function wiced_bt_iap2_tx_complete_callback.

Transmission Complete callback indicates that application can send more data.

Parameters

[in]	handle	: Handle that identifies the external accessory session
[in]	result	: Result of tx operaion. 0 if success.

Returns: Nothing

Function Documentation

wiced_bool_t wiced_bt_iap2_can_send_more_data ( void )

Function wiced_bt_iap2_can_send_more_data.

Returns TRUE if library can queue forward data, or FALSE if forward data queue is full.

void wiced_bt_iap2_connect ( uint8_t * bd_addr )

Function wiced_bt_iap2_connect.

Establish External Accessory connection to an iOS device. Library will perform Service Discovery. If iAP2 service is running on the specified device RFCOMM connection is established. If connection is established, accessory initiates iAP negotiations which includes accessory authentication and identification. Application on the device is responsible to start External Accessory Session. When session is established, library executes iap2_connection_up_callback.

Parameters

[out] bd_addr : Bluetooth Device address to connect to.

Returns: Nothing

void wiced_bt_iap2_disconnect ( uint16_t handle )

Function wiced_bt_iap2_disconnect.

Disconnect External Accessory Session with the iOS device. Bluetooth connection is brought down as well.

Parameters

[out] handle : The handle returned by the application in the wiced_bt_iap2_connection_up_callback.

Returns: Nothing

wiced_result_t wiced_bt_iap2_get_auth_chip_info	(	uint8_t *	buffer,
		uint32_t	buffer_size
	)

Function wiced_bt_iap2_get_auth_chip_info.

Read the auth chip info

Parameters

[out]	buffer	:Pointer to buffer to get the auth chip info
[out]	buffer_size	:buffer size

Returns: Status

uint8_t wiced_bt_iap2_get_connection_state ( uint8_t * bd_addr )

iAP2 application use this function to get the connection state with the peer specified by btaddr

Returns: connection state

void wiced_bt_iap2_port_purge	(	uint16_t	handle,
		uint8_t	purge_flags
	)

iAP2 application may use this function to discard all the data from the output or input queues of the specified connection.

Parameters

[in]	handle	: Connection handle indicated in the connection up callback
[in]	purge_flags	- specify the action to take with PORT_PURGE_TXCLEAR and/or PORT_PURGE_RXCLEAR.

Returns: rfcomm port return code

uint16_t wiced_bt_iap2_rfcomm_get_peer_mtu ( uint16_t handle )

iAP2 application use this function to read the peer_mtu size when rfcomm connection made

Returns: rfcomm port peer mtu size

void wiced_bt_iap2_rx_flow_enable	(	uint16_t	session,
		wiced_bool_t	enable
	)

Function wiced_bt_iap2_rx_flow_enable.

IAP2 application may use this call to disable or reenable the RX data flow

Parameters

[out]	session	: Must always be IAP2_EA_SESSION_ID
[out]	enable	: If true, data flow is enabled

Returns: Nothing

wiced_bool_t wiced_bt_iap2_send_session_data	(	uint16_t	session,
		uint8_t *	p_data,
		uint32_t	len
	)

Function wiced_bt_iap2_send_session_data.

Send data over the established External Accessory connection. The session must be IAP2_EA_SESSION_ID. The first 2 octets of the p_data must be the handle passed to the application in the wiced_bt_iap2_connection_up_callback in the big endian format.

Parameters

[out]	session	: Must always be IAP2_EA_SESSION_ID
[out]	p_data	: Pointer to buffer with data to send. The first 2 octets of the p_data must be the handle passed to the application in the wiced_bt_iap2_connection_up_callback in the big endian format.
[out]	len	: Length of the data + handle

Returns: WICED_TRUE: if data is scheduled for transmission, otherwise WICED_FALSE

void wiced_bt_iap2_startup ( wiced_bt_iap2_reg_t * p_reg )

Function wiced_bt_iap2_startup.

Initialize IAP2 library and starts the RFCOMM service.

Parameters

[out] p_reg : Registration control block that includes RFCOMM SCN and callbacks

Returns: Nothing
