We use the "simple-agent" script from test/ directory in BlueZ for pairing.
On the slave side run:
test/simple-agent hci0
on the master side, after "hcitool lescan", run:
test/simple-agent hci0 <slave-address>
This should trigger Just Works SMP pairing.

ya , i got your point ,advertiser is informing the remote device ,
that it is not BR/EDR capable .That is done and device is connecting now.
But still i dont know, how to do le specific pairing and
start_encryption enable(part of le pairing) . Is there any tool in bluez
providing LE pairing before connecting the devices (want to try with 2
ubuntu pc's ).

No, this sets adv. data to have "Flags" AD set to 0x06. But you missed
the second line of the command:
sudo hcitool -i hci0 cmd 0x08 0x0008 03 02 01 06 \
$(perl -e 'print "00 " x 28')
The second line is important because it fills the other bytes with
zero (which some controllers require).

Thanks, but "sudo hcitool -i hci0 cmd 0x08 0x0008 03 02 01 06 " , this
command only sets the advertising data to zero right . so how do i set
the adv flag as 0x06 . Which hci command is used for this purpose .

You can try using the --sec-level medium option.

I suspect this check has been added recently to the kernel. Try
running bluetoothd oh the master side as well, it should then enable
host LE support through mgmt API and this check should pass.

Hi,
I tried "gatttool -i hci0 -b <remote bdaddr> --primary " on
master side ,which creates LE link and very next moment disconnects .
How can i change the security level of the link to medium?. still
struggling to pair the device (atleast "smp just works") ) . Is my
kernel supportive (3.2.5)
few lines of code from the kernel (/net/bluetooth/smp.c)
int smp_conn_security(struct l2cap_conn *conn, __u8 sec_level)
{
struct hci_conn *hcon = conn->hcon;
struct smp_chan *smp = conn->smp_chan;
BT_DBG("conn %p hcon %p level 0x%2.2x", conn, hcon, sec_level);
if (!lmp_host_le_capable(hcon->hdev))
return 1;
if (sec_level == BT_SECURITY_LOW)
return 1;
if (hcon->sec_level >= sec_level)
return 1;
if (hcon->link_mode & HCI_LM_MASTER)
if (smp_ltk_encrypt(conn))
goto done;
if (test_and_set_bit(HCI_CONN_LE_SMP_PEND, &hcon->pend))
return 0;
smp = smp_chan_create(conn);
if (hcon->link_mode & HCI_LM_MASTER) {
struct smp_cmd_pairing cp;
build_pairing_cmd(conn, &cp, NULL, SMP_AUTH_NONE);
smp->preq[0] = SMP_CMD_PAIRING_REQ;
memcpy(&smp->preq[1], &cp, sizeof(cp));
smp_send_cmd(conn, SMP_CMD_PAIRING_REQ, sizeof(cp), &cp);
Every time on LE create connection process i ,smp_conn_security()
getting called from hci layer .
But if(host_le_capable(hcon->hdev))
return 1;
condition returns without even checking the security level . so kindly
show me the right way..

Your slave device is not answering to the Read By Group request,
therefore the master side is disconnecting due to timeout.
I suggest you first try using gatttool on the master side to connect
to the slave, and run "primary" to see if it is processing GATT
requests.
The bluez log from the slave side should help (I assume you are
running BlueZ on the slave side).

To connect to a dual mode dongle, you need to set LE Adv. flags to
0x06 (which means general discoverable + BR/EDR not supported) on the
acceptor side. You can use this command (on the acceptor/slave side):
sudo hcitool -i hci0 cmd 0x08 0x0008 03 02 01 06 \
$(perl -e 'print "00 " x 28')
Next, enable LE advertising:
sudo hciconfig hci0 leadv
On the initiator/master side, run "hcitool lescan" and try pairing again.

No, this sets adv. data to have "Flags" AD set to 0x06. But you missed
the second line of the command:
sudo hcitool -i hci0 cmd 0x08 0x0008 03 02 01 06 \
$(perl -e 'print "00 " x 28')
The second line is important because it fills the other bytes with
zero (which some controllers require).

Hi,
I have included some of our previous conversations related to this
issue.
I got some error while testing the above case for LE pairing using
simple_agent . kindly find a solution
MASTER side
Steps followed
root@test:/home# hcitool lescan
root@test:/home# ./simple-agent hci0 00:02:72:D6:A1:0D
Creating device failed: org.freedesktop.DBus.Error.NoReply: Did not
receive a reply. Possible causes include: the remote application did not
send a reply, the message bus security policy blocked the reply, the
reply timeout expired, or the network connection was broken.
