I have a some questions. Couldnt find answer anywhere.

If I am using an arduino connected to the serial port on a Raspberry pi (w/openhab) How do I assign fw, reboot, etc?

Do I need to disconnect the GW and use windows temporarily to reboot, update fw? or can I have 2 GW's?

I updated my nano with the MYS bootloader, and after I power it on, it never shows up in MYSController.
