Bottango communicates with hardware drivers via a serial connection. Your user may not have permission to open a serial port. If you are seeing "Permission Denied" in Bottango when attempting to connect to a serial driver, follow these steps:


1) Run in a terminal:

$ id -Gn <USERNAME>

if, for example, your username is "Bob", you would run "id -Gn Bob" This will show if your user is a member of the "dialout" group. If "dialout" is not one of the listed groups, then you need to add it.


2) Next run: 

$ sudo usermod -a -G dialout <USERNAME>
Then enter your user password.

This will add the user to the "dialout" group. Finally, to confirm that you have added your username to the "dialout" group,

3) Finally, run again:

$ id -Gn <USERNAME>

You should see "dialout" as one of the listed groups.

4) In order for the change to take effect you must first RESTART YOUR COMPUTER. As well, you should go through this process on any other users that you wish to use Bottango.
