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!
