Problems with asebaswitch

Simon Studer 10 Dec 2013 09:46

Hi, I'm having trouble connecting to e-pucks. This problem occurred on several machines, others on others it worked fine.
Right now I'm running Ubuntu 13.10 and installed aseba with the corresponding package.
When I try to connect, I get the following output:

simu@simu-Samsung-Ubuntu:~$ hcitool scan
Scanning ...
    10:00:E8:52:C3:F6    e-puck_1489
simu@simu-Samsung-Ubuntu:~$ sudo rfcomm bind 0 10:00:E8:52:C3:F6
simu@simu-Samsung-Ubuntu:~$ asebaswitch -v ser:device=/dev/rfcomm0
Cannot open serial port.

Please let me know if you need additional information.

Thanks in advance,
Simon

Maybe your user does not have the rights to access the serial port? Try to do a ls -l /dev/rfcomm0 to see which group has the right, and then type id to see if your user is in that group.

add your user to the dialout group, and uninstall modemmanager.

Thank you for your answers!

It was indeed a problem of permissions. Adding sudo before the asebaswitch command was enough to make it work.

Greetings,
Simon

Even though we do not ship viruses with Aseba, it is safer to add your user to the dialout group than using sudo ;-)
