Re: [Bluez-devel] connect() and L2CAP_CONN_TIMEOUT

[Marco Pracucci <development@pracucci.com>]

Hi Marcel,

I have dump it (hcidump -i hci1 -t -X -V). Here I publish only
interesting commands and events:

2006-08-10 11:10:51.168745 < HCI Command: Create Connection

No other related event has been received, but the connect() system call
returns after 40 seconds (2006-08-10 11:11:31). Have you any idea and/or
suggestion?

P.S. bdaddr 7B:00:00:01:C3:E0 is wrong: is it a little bug of hcidump?
