Re: [Bluez-users] Two simultanous connections

hcitool -a shows "invalid option -- a".
This is the bluetooth chip of an iPaq 3970. It's running Familiar
stable, so it must be a pretty old bluez version. Don't know if it
helps...

Ok, I knew I had to give more details... I create links between 3 iPaqs.
I tried using higher layer protocols to do so. Never worked. I'm just
trying to do a TCP/IP network so I can run XML-RPC on top of it, ssh
etc...

That's all I need. I tried to use pan, never worked, I tried to use dun
over pan, never worked, I tried to use rfcomm never worked. Always the
same problem:
I could connect A to B and B to C, never B to A and C to A. 

Now I went the hcitool route. Created my own connections very very
easily. I connected B to A and C to A (A master). Ran dund _after_
hcitool connections and everything is running great.

hcitool con on A gives me two master connections. These connections have
been initialised from B and C as slave. So I can have two master
connections, but I can't create them from A. First one works, second one
doesn't, nothing happen. It's just out of curiosity.
