Hi, 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
