BLE : SMP pairing + LE_Start_encryption

Hi,
	how do i do smp pairing and ltk key distribution using l2cap socket 
connection?  does bluez provide any tools for LE pairing . my ultimate 
result should be enabling LE_start_encryption , which requires ltk key 
distribution (which is a part of LE_pairing).

	spec 4.0  says we can use l2cap cid 0x06 , defined for this purpose 
(smp pairing) . But when i used cid =0x06 , l2cap connect  creates an 
normal acl connection with cid = 40 , which doesnt trigger any smp 
modules at remote side.

	please look into this issue.
