Hello everyone,
I am new here,
I try to use OpenSCADA on Android TV-Box with Arduino-Uno modbus RTU and others USB2Serial RTU.
I can't connect to /dev/tty* , I got error "Error the serial port '/dev/bus/usb/001/003' open: Permission denied."
I try to change many usb2serial devices, The Errors are same.
How to fix. please
Thank You

That is not about OpenSCADA development and OpenSCADA in whole!
That is about missing such devices' drivers-modules in the Linux kernel on Android and the device path "/dev/bus/usb/001/003" is wrong!
So, search such Android packages.
Learn, learn and learn better than work, work and work.
