Detailed Description

API for L2CAP layer.

Function Documentation

aci_l2cap_connection_parameter_update_request()

tBleStatus aci_l2cap_connection_parameter_update_request	(	uint16_t	conn_handle,
		uint16_t	interval_min,
		uint16_t	interval_max,
		uint16_t	slave_latency,
		uint16_t	timeout_multiplier
	)

Send an L2CAP Connection Parameter Update request from the slave to the master.

Note

An EVT_BLUE_L2CAP_CONN_UPD_RESP event will be raised when the master will respond to the request (accepts or rejects).

Parameters

conn_handle	Connection handle on which the connection parameter update request has to be sent.
interval_min	Defines minimum value for the connection event interval in the following manner: connIntervalMin = interval_min x 1.25ms
interval_max	Defines maximum value for the connection event interval in the following manner: connIntervalMax = interval_max x 1.25ms
slave_latency	Defines the slave latency parameter (number of connection events that can be skipped).
timeout_multiplier	Defines connection timeout parameter in the following manner: timeout_multiplier x 10ms.

Returns

Value indicating success or error code.

aci_l2cap_connection_parameter_update_response_IDB04A1()

tBleStatus aci_l2cap_connection_parameter_update_response_IDB04A1	(	uint16_t	conn_handle,
		uint16_t	interval_min,
		uint16_t	interval_max,
		uint16_t	slave_latency,
		uint16_t	timeout_multiplier,
		uint8_t	id,
		uint8_t	accept
	)

Accept or reject a connection update.

Note

This command should be sent in response to a EVT_BLUE_L2CAP_CONN_UPD_REQ event from the controller. The accept parameter has to be set if the connection parameters given in the event are acceptable.

Parameters

conn_handle	Handle received in EVT_BLUE_L2CAP_CONN_UPD_REQ event.
interval_min	The connection interval parameter as received in the l2cap connection update request event
interval_max	The maximum connection interval parameter as received in the l2cap connection update request event.
slave_latency	The slave latency parameter as received in the l2cap connection update request event.
timeout_multiplier	The supervision connection timeout parameter as received in the l2cap connection update request event.
id	Identifier received in EVT_BLUE_L2CAP_CONN_UPD_REQ event.
accept	0x00: The connection update parameters are not acceptable. 0x01: The connection update parameters are acceptable.

Returns

Value indicating success or error code.

aci_l2cap_connection_parameter_update_response_IDB05A1()

tBleStatus aci_l2cap_connection_parameter_update_response_IDB05A1	(	uint16_t	conn_handle,
		uint16_t	interval_min,
		uint16_t	interval_max,
		uint16_t	slave_latency,
		uint16_t	timeout_multiplier,
		uint16_t	min_ce_length,
		uint16_t	max_ce_length,
		uint8_t	id,
		uint8_t	accept
	)

Accept or reject a connection update.

Note

This command should be sent in response to a EVT_BLUE_L2CAP_CONN_UPD_REQ event from the controller. The accept parameter has to be set if the connection parameters given in the event are acceptable.

Parameters

conn_handle	Handle received in EVT_BLUE_L2CAP_CONN_UPD_REQ event.
interval_min	The connection interval parameter as received in the l2cap connection update request event
interval_max	The maximum connection interval parameter as received in the l2cap connection update request event.
slave_latency	The slave latency parameter as received in the l2cap connection update request event.
timeout_multiplier	The supervision connection timeout parameter as received in the l2cap connection update request event.
min_ce_length	Minimum length of connection event needed for the LE connection. Range: 0x0000 - 0xFFFF Time = N x 0.625 msec.
max_ce_length	Maximum length of connection event needed for the LE connection. Range: 0x0000 - 0xFFFF Time = N x 0.625 msec.
id	Identifier received in EVT_BLUE_L2CAP_CONN_UPD_REQ event.
accept	0x00: The connection update parameters are not acceptable. 0x01: The connection update parameters are acceptable.

Returns

Value indicating success or error code.
