I'm having some issues when I turn the tinyg off and back on again

I’m having some issues when I turn the tinyg off and back on again it doesn’t appear in the port list.

Here is a screen grab of what happens.

My gut is telling me it’s because your Mac OS isn’t detecting it when you turn it back on. That list is a pretty raw list from the operating system. If it showed up before, but not after, my gut is that it’s not Serial Port JSON Server.

Does your user have permission to access the serial port? Try running with ‘sudo’ before ‘./serial-port-json-server’ and see if that helps!

Oh, to give your user permission to access serial ports and other physical tty devices, use the following:
sudo usermod -aG dialout <your_username>

Don’t forget to not put in the <> around your username.

Thanks for advice Andy and John! I’ll definitely try it when come back from holiday.

@Jody_Koomen you’re welcome!

I spent a while trying to debug this. It seems to be a bug with the FTDI drivers in macOS, and it seems to happen when you disconnect the external power from the TinyG before unplugging the USB. Restarting macOS fixes the problem.
