I have spent a good deal of time trying to get this device to work with my linux box, and I was hoping somebody could provide some insight.
So far, I have managed to pair with the Arduino, create the /dev/rfcomm0 device with the bind command as stated on the "getting started" page. I have installed the Arduino package, and can open the IDE no problem.
The problem is when I try to upload a sketch, all I get is
avrdude: ser_open(): can't open device "/dev/rfcomm0": Host is down
I can ping the device with l2ping. I can see the rfcomm0 device (but when I try to do anything with it, also with the "host is down").
What am I missing? I plugged the thing into the Windows XP box right next to it with the same BT module and it works fine.
