Hi everyone!
I have a application running that reads info from 2 devices connected in serial port mode. The thing is I have this app running in a Dell that uses Ubuntu Core, so when type "snap logs node-red" it displays an error on serial port (now I only have one device connected, when solved I will connect both devices):
> 2018-11-02T11:49:19Z node-red.node-red[4692]: 2 Nov 11:49:19 - [info] Starting flows
> 2018-11-02T11:49:19Z node-red.node-red[4692]: 2 Nov 11:49:19 - [info] Started flows
> 2018-11-02T11:49:19Z node-red.node-red[4692]: 2 Nov 11:49:19 - [error] serial port /dev/ttyACM0 error: Error: Error: Permission denied, cannot open /dev/ttyACM0
I know it's a permission problem, but i'm new in Ubuntu and don't know how to solve it. What folders or files have node-red permission? Node-Red is installed in home/admin
Thanks in advance
