can you please tell what 'c0:7a:a5:00:c7:11' is? is this a remove address?
looking at your previous emails, i *think*, 'c0:7a:a5:00:c7:11' is a
remote address. if this is the case, then, l2control is not going to
work. from the l2control(8) man page
==
-a local
Connect to the local device with the specified BD_ADDR or name.
Example: -a 00:01:02:03:04:05 or -a bt_device.
==
more specifically, the read_channel_list command will list l2cap
channels open on the local device.
i'm not exactly sure what are you trying to do here.

ok. this tells me that hci and l2cap communication works
> So, what to do with the "network down" - problem?
you have asked l2control to bind to the *local* bd_addr
(c0:7a:a5:00:c7:11). and since there is no *local* bluetooth device
with this bd_addr, l2control returns "network down". l2control will
only work for *local* bd_addr's
thanks
