Im using the serial gateway on u17 and have it working fine. i have the same problem as you when my vera is rebooted or powered off, but found 2 solutions. 1 with the vera on disconnect then reconnect the serial gateway. wait 10seconds refresh the dashboard page. Then go to app/ developer apps/ serial connection. Reset your baud rate to 115200??...

Thansk. I ended up upgrading to the latst UI7 beta. My gateway is now working!!! Let's see how stable it is. ;-)

(UI7 has fixed some of my other issue too)

thanks everyone for your comments and suggestions. I don't want to try a different tech just yet (ethernet), someone recommended to me to downgrad back to UI5. I am doing this now (to beta version 672) and will let you know how it goes.

cheers

@cdrum Try this - http://forum.mysensors.org/topic/269/lost-usb-serial-port-connection-on-vera-3-again/8

Hi blacey, thanks but tried that and didn't work :(

Hi,

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!
