I built my gw using a nano (bought the one recommended on this site) many months ago. It worked for a while, but then I unplugged it from my Vera Lite (running UI6) as my sensors weren't fully operational yet (had some battery issues).
Now that I have some time, I tried getting the gw to work again, and when I follow the instructions on the page http://www.mysensors.org/controller/vera, I keep seeing the "Lua Startup Failure" error on the device page. When I go to set the serial port, I get the "Not available." message on the "Set Serial Configuration" page in the Apps section.
I SSH into the vera as the remote user to tail some logs (/tmp/log/cmh/LuaUPnP.log) and when I reload Lua, I see the following log entries relevant to the gw device (#37):

So it seems it loads the library fine, but something goes wrong and it fails. Just to make sure my nano is still working, I uploaded the blink sketch, and that worked.
I also tried, as someone suggested in this forum, to use a powered hub (as opposed to plugging the nano directly into the VeraLite - same result.
Anyone had a similar issue and found a way to resolve it? I saw someone else in this forum had better luck with a legit Nano ($$$), I am hoping I don't have to do that
Thanks in advance!
