Hi,

I have two identical BT-Dongles and I want to make my first steps on
programming with bluez. For the first quick and dirty I tried to connect
these two dongles on different PCs over a RFCOMM channel. The server comes
up and is waiting, but the client breaks the connect with "Connection
refused". What can I do? How can I debug or find out more information about
whats going wrong? Can I switch to verbose output for the bluez-daemons?

Both PCs are on Debian Sarge 2.4.27 with whole bluez-stuff compiled in the
kernel and the additional bluez-packages. The "hcid.conf" and "pin" are
identical on both PCs, for testing the security is none. "l2ping" and the
other basic tests are working. "hciconfig -a" and "hcitool scan" looks good,
but sdptool browse xxxx shows only "L2CAP" on protocol-lists, no RFCOMM
(look at the end of email). All internet examples have the rfcomm on the
protocol list ??!

Thanks for your help,
Ralf
