Parameters

[in]	bd_addr	The remote BD address of ACL link. If it is BT_DB_ANY then the flush time out will be applied to all ACL link.
[in]	flush_timeout	flush time out in ms 0x0000 : No automatic flush L2CAP_NO_RETRANSMISSION : No retransmission 0x0002 - 0xFFFE : flush time out, if (flush_timeout*8)+3/5) <= HCI_MAX_AUTO_FLUSH_TOUT (in 625us slot). Otherwise, return FALSE. L2CAP_NO_AUTOMATIC_FLUSH : No automatic flush

Returns: TRUE if command succeeded, FALSE if failed

NOTE This flush timeout applies to all logical channels active on the ACL link. BD_Address must be in Big Endian format

wiced_bool_t wiced_bt_l2cap_set_idle_timeout	(	uint16_t	cid,
		uint16_t	timeout,
		wiced_bool_t	is_global
	)

Function wiced_bt_l2cap_set_idle_timeout.

Higher layers call this function to set the idle timeout for a connection, or for all future connections. The "idle timeout" is the amount of time that a connection can remain up with no L2CAP channels on it. A timeout of zero means that the connection will be torn down immediately when the last channel is removed. A timeout of 0xFFFF means no timeout. Values are in seconds.

Parameters

[in]	cid	CID value
[in]	timeout	Timeout value
[in]	is_global	TRUE, if global

Returns: TRUE if command succeeded, FALSE if failed

wiced_bool_t wiced_bt_l2cap_set_idle_timeout_by_bd_addr	(	wiced_bt_device_address_t	bd_addr,
		uint16_t	timeout,
		tBT_TRANSPORT	transport
	)

Function wiced_bt_l2cap_set_idle_timeout_by_bd_addr.

Higher layers call this function to set the idle timeout for a connection. The "idle timeout" is the amount of time that a connection can remain up with no L2CAP channels on it. A timeout of zero means that the connection will be torn down immediately when the last channel is removed. A timeout of 0xFFFF means no timeout. Values are in seconds. A bd_addr is the remote BD address. If bd_addr = BT_BD_ANY, then the idle timeouts for all active l2cap links will be changed.

Parameters

[in]	bd_addr	BD Address
[in]	timeout	Timeout value

Returns: TRUE if command succeeded, FALSE if failed

NOTE This timeout applies to all logical channels active on the ACL link. BD_Address must be in Big Endian format

uint8_t wiced_bt_l2cap_set_trace_level ( uint8_t trace_level )

Function wiced_bt_l2cap_set_trace_level.

This function sets the trace level for L2CAP. If called with a value of 0xFF, it simply reads the current trace level.

Parameters

[in] trace_level Trace level

Returns: the new (current) trace level

wiced_bool_t wiced_bt_l2cap_set_tx_priority	(	uint16_t	cid,
		wiced_bt_l2cap_chnl_priority_t	priority
	)

Function wiced_bt_l2cap_set_tx_priority.

Sets the transmission priority for a channel. (FCR Mode)

Parameters

[in]	cid	CID
[in]	priority	[L2CAP_PRIORITY_NORMAL \| L2CAP_PRIORITY_HIGH]

Returns: TRUE if a valid channel, else FALSE

wiced_bool_t wiced_bt_l2cap_update_ble_conn_params	(	wiced_bt_device_address_t	rem_bdRa,
		uint16_t	min_int,
		uint16_t	max_int,
		uint16_t	latency,
		uint16_t	timeout
	)

Function wiced_bt_l2cap_update_ble_conn_params.

Update LE connection parameters.

Parameters

[in]	rem_bdRa	Remote BD Address
[in]	min_int	Min interval
[in]	max_int	Max interval
[in]	latency	Latency value
[in]	timeout	Timeout value

Returns: : TRUE if update started
