[Jonathan Bredin]

Thanks, Marcel.  I tried using the connect option with the same result, except that I get a few new messages in the log.

I made sure that pand was dead, restarted the bluetooth services, plugged in the adaptor, started pand with the connect and tried to bring up bnep0 with ifup and ifconfig....  

/var/log/messages:
Mar 28 12:53:57 ma-jbredin hcid[11737]: Bluetooth HCI daemon

Any more thoughts?

run "hcidump -X -V" as root at the same time, but I am pretty sure that
"Host is down" means that your other device is not in connectable mode.

[Jonathan Bredin]

Thanks, Anderson and Marcel. 

I think that I must have been too slow in moving between the two 
devices....  bnep0 comes up at both sites, now.

At the slave side, though, I get
NETDEV WATCHDOG: bnep0: transmit timed out
once I try to use the connection.  I'll dig around and see if can figure 
it out.

Thanks!

jonathan
