Function Documentation

SVCALL	(	SD_BLE_L2CAP_CID_REGISTER	,
		uint32_t	,
		sd_ble_l2cap_cid_register(uint16_t cid)
	)

Register a CID with L2CAP.

This registers a higher protocol layer with the L2CAP multiplexer, and is requried prior to all operations on the CID.

Parameters:

[in] cid L2CAP CID.

Returns:: NRF_SUCCESS Successfully registered a CID with the L2CAP layer.; NRF_ERROR_INVALID_PARAM Invalid parameter(s) supplied, CID must be above BLE_L2CAP_CID_DYN_BASE.; BLE_ERROR_L2CAP_CID_IN_USE L2CAP CID already in use.; NRF_ERROR_NO_MEM Not enough memory to complete operation.

SVCALL	(	SD_BLE_L2CAP_TX	,
		uint32_t	,
		sd_ble_l2cap_tx(uint16_t conn_handle, ble_l2cap_header_t const const p_header, uint8_t const const p_data)
	)

Transmit an L2CAP packet.

Note:: It is important to note that a call to this function will consume an application buffer, and will therefore generate a BLE_EVT_TX_COMPLETE event when the packet has been transmitted. Please see the documentation of sd_ble_tx_buffer_count_get for more details.

Parameters:

[in]	conn_handle	Connection Handle.
[in]	p_header	Pointer to a packet header containing length and CID.
[in]	p_data	Pointer to the data to be transmitted.

Returns:: NRF_SUCCESS Successfully queued an L2CAP packet for transmission.; NRF_ERROR_INVALID_ADDR Invalid pointer supplied.; NRF_ERROR_INVALID_PARAM Invalid parameter(s) supplied, CIDs must be registered beforehand with sd_ble_l2cap_cid_register.; NRF_ERROR_NOT_FOUND CID not found.; NRF_ERROR_NO_MEM Not enough memory to complete operation.; BLE_ERROR_NO_TX_BUFFERS Not enough application buffers available.; NRF_ERROR_DATA_SIZE Invalid data size(s) supplied, see BLE_L2CAP_MTU_DEF.

SVCALL	(	SD_BLE_L2CAP_CID_UNREGISTER	,
		uint32_t	,
		sd_ble_l2cap_cid_unregister(uint16_t cid)
	)

Unregister a CID with L2CAP.

This unregisters a previously registerd higher protocol layer with the L2CAP multiplexer.

Parameters:

[in] cid L2CAP CID.

Returns:: NRF_SUCCESS Successfully unregistered the CID.; NRF_ERROR_INVALID_PARAM Invalid parameter(s) supplied.; NRF_ERROR_NOT_FOUND CID not previously registered.
