Permission error /dev/ttys0/

To preface: I experimented with RVR a while ago but then got lost with other stuff. I am trying to get back to RVR but when I try to run the sample keyboard control to check if my setup is working I get this error:

serial.serialutil.SerialException: [Errno 13] could not open port /dev/ttyS0: [Errno 13] Permission denied: '/dev/ttyS0'

Any suggestions as to what I can do?

  • I tried to change wires but no luck;

Hi @h4rsh4,
I’m not a linux expert at all, but do you know if there is another program using that port?
What setup do you have for your project?

I haven’t hooked anything else to the pi and only the rvr is connected so far. I checked if the wires were set up right, they are.

Software wise:
I am using the latest raspbian, and the basic pipenv that comes with the sdk.
