I'm actually working on a project where I need embedded devices to communicate between them. We decided to use bluetooth dongles and pan to build a piconet.
Actually this work fine when we have only 3 devices : 1 GN & 2 PANU (PANU#1 & PANU#2). When we try to add a third PANU (PANU#3), pand say the host is down. If I shut down the connection of one of the two thers PANU, I'm able to establish a connection with PANU#3 to the GN. I try to setup a different GN on a linux desktop, same result, 1 GN & 2 PANU.

On my server I do this :
pand --listen --nosdp --role GN -i yy:yy:yy:yy:yy:yy
I use brctl on the GN to bridge the interface

On my clients I do this :
pand --nodetach -i xx:xx:xx:xx:xx:xx --role PANU --connect yy:yy:yy:yy:yy:yy

On connected PANU i have :
pand[7334]: Bluetooth PAN daemon version 2.25
pand[7334]: Connecting to yy:yy:yy:yy:yy:yy
pand[7334]: bnep0 connected

On PANU's I can't connect:
pand[8492]: Bluetooth PAN daemon version 2.25
pand[8492]: Connecting to yy:yy:yy:yy:yy:yy
pand[8492]: Connect to yy:yy:yy:yy:yy:yy failed. Host is down(112)

I have read & reread the HOWTO-PAN. I mainly used it to setup my pan.
I know there is a limitation of 7 PANU max but there I'm far away of the 7 devices. Is there is something I have forgotten ? misconfigured ... ? A problem with my dongles ?
If anyone could help me

Laurent
