[Bluez-users] Bluetooth Scatternet

[Bluez-users] Bluetooth Scatternet

[Ronan Naughton]

Hi all,
Has anyone ever implemented a bluetooth scatternet using pan over bnep.
I have two simple piconets running at the moment and want to join them.  How 
will I assign it so that a node can be a slave in both piconets. Do i need 
two bnep connections. Or should I have a node to be a master in one piconet 
and a slave in an other. How is this implemented?
Any ideas?
Ronan.

you need a scatternet capable Bluetooth chip, which means a chip which
can be master in one and slave in another or slave in two different
piconets. Actually you form a scatternet if one of these two conditions
are present and each connection will have its own BNEP connection.

Ya, I can do that. I can connect to one pan using bnep0 acting as a slave. 
Then I can make it a master on bnep1 and conncet to it form another pc. When 
I do "pand --show", it shows both interfaces bnep0 and bnep1 and their 
connections.
However, I cannot communicate between the two networks. When I even try to 
ping the master of the other network it comes up host unreachable. I don't 
know why this is?

this is not a Bluetooth problem, because this is TCP/IP stuff. You
should read somehting about IP forwarding, bridging, routing etc.
