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).

Either using mgmt API to do pairing (see mgmt_create_bonding() in
src/mgmt.c from bluez sources and doc/mgmt-api.txt for how to do this)
or increase socket security level to at least medium using
setsockopt() (see set_sec_level() in btio/btio.c for how to do this).

In summary, you will need to use BlueZ code as reference if you want
to do these things on your own. The easier route is to use BlueZ D-Bus
API to do pairing.

Regards,

  thanks  Anderson ,
   sorry if im confusing you .
	is it possible to create an l2cap connection with cid 0x06 and psm 0 ? 
  , so that i can make use of dedicated smp-l2cap channel for data 
transfer . I wanted to try how the remote device is handling on 
receiving an smp_pairing_request . i have seen in l2cap_core.c	 , it is 
getting handled inside a switch case (case cid == L2CAP_CID_SMP).
