Hi
I am using bluez on Gentoo and meet a problem recently.
I was trying to connect to a medical device via bluetooth.
(00:11:B1:B3:4E:B4 clock offset: 0x1242 class: 0x001f00). When I
connect it at first, it works. However, if I accidentally shut off the
device manually and reconnect it, I got the failed message like this,
localhost ~ # rfcomm connect 0 00:11:B1:B3:4E:B4 1
Can't connect RFCOMM socket: Permission denied
The message from hcidump is
localhost ~ # hcidump hci0

Error: Authentication Failure
So I think I should clean up some residues to finish the process of
authentication. But I don't know where they are under linux filesystem
hierarchy. Of course I can delete them through some GUI bluetooth
manager like gnome-bluetooth. But my supervisor expects that I can
write a code to clean them up.
Can anyone help me?
Thanks
Cheng
