Subject: [Bluez-users] bluetooth clock and security manager

Hi,
I want to read local bluetooth clock with hcitool. But when I=
use the command "hcitool clock XX:XX:XX:XX:XX:XX=A3=A8local=
bd_addr)",the return message is "not connected",and I am sure=
that I have created one ACL link.
So, I use "hcitool clock XX:XX:XX:XX:XX:XX=A3=A8remote=
bd_addr)",the reture message is "read failed,Input/output=
error",but the command "hcitool clkoff" works good.
Now,I have to read the local device clock or the remote=
clock,what shall I do?
There is another question about security mananger within=
BlueZ.
I have paired my pda with BlueZ successfully,but I want to make=
it clearly that how to add authenticated device into the=
security manager in programming ,and where do these=
authenticated device go?
Thanks.

the clock reading is a Bluetooth 1.2 feature. So make sure that you use
Bluetooth 1.2 device that supports this HCI command.

The current security manager is inside hcid. The link keys are stored
at /etc/bluetooth/link_key.
