you can't have to ACL links to the same remote device.

Check with "hcitool con" every time, because this is what the kernel
sees and "hcitool dc" only sends the raw HCI_Disconnect command.

Re: [Bluez-users] BlueZ error in cc,cc,dc sequence

There is another problem which I in mistake found.

I tried connect to my mobile phone via cc
then I moved console, remembered it and called cc second time.
It told me, that connection is created - which is right.
Then I wanted disconnect later, but I got message that there isn't any 
connection, which is bad, coz devices are connected.

when calling cc/dc/cc/dc/cc/dc it works like a charm
but cc/cc/dc makes problems - can't disconnect

maybe the kernel or your Bluetooth chip don't really likes double
HCI_Create_Connection. If you use higher layers like L2CAP or RFCOMM
this can't happen.

If I don't need the hcitool cc/dc functions for development I had
already removed them ;)

Marcel

if it is really a kernel problem then it is present in every kernel,
because I never worked on it.

Hi Michal,

> So it is good that I found it :)

right now I am not sure what the problem is and I have no time for
further investigations, because in general hcitool cc/dc should not be
used for ACL link creation. But feel free to do it by yourself.

Regards

Marcel
