Re: [Bluez-users] pand, bnep0 and no traffic flow

[Andy Brown <andy@thebmwz3.co.uk>]

Thanks for that, I've made that change so the server is now showing:
hci0:   Type: USB
         BD Address: 00:02:72:B2:EF:DF ACL MTU: 192:8 SCO MTU: 64:8
         UP RUNNING PSCAN ISCAN
         RX bytes:3469781 acl:40952 sco:0 events:104252 errors:0
         TX bytes:1084252 acl:25246 sco:0 commands:35803 errors:0

but still no luck.

I have also checked and on the client and server, I have done an rfcomm =

bind to a bluetooth GPS and that works fine, so the adapters are =

definately functioning correctly.

Regards,

Andy
