Why not the Uno as a Serial Gateway

  • Mod

    So, I received my radio's today and got everything up in about 10 minutes 🙂

    Nice stuff guys so now my work on the Indigo Plugin begins...

    One question though: I tried to compile the Uno as a gateway and, as mentioned, it did not work.

    Is there a specific reason why not?

    I have a quite a few Uno's lying around and would not mind using one of these as a gateway or can I use them to compile a repeater?

    You should be able to compile and run the serial gateways sketch on an Uno. But the Vera controller won't recognize it.
    It might be possible to use Uno with some other device that recognizes the Uno Serial-USB.

    The Uno differs from all preceding boards in that it does not use the FTDI USB-to-serial driver chip. Instead, it features the Atmega16U2 (Atmega8U2 up to version R2) programmed as a USB-to-serial converter. (from here: http://arduino.cc/en/Main/arduinoBoardUno)

    Hmm, the Uno gave me nothing except a startup message whereas the Nano does its jobs from the 1st second...

    Anyway, not important right now. Will look into this later when I have the first part of the plugin working.

  • The Uno works fine as a serial gateway. I have one running for 5+ month connected to a Raspberry Pi, using stock mysensor code.

    In short it looks like some (in my case all except one) Uno boards seem to under power the 3.3v pin...
