[Bluez-users] bluetooth clock and security manager

[Jin Pu]

  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.
