Gateway not working on VeraLite + UI6 - No Serial Port configuration available



  • 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):

    09	02/22/15 12:11:02.086	JobHandler_LuaUPnP::Run device 37 MySensors Plugin room 0 type urn:schemas-arduino-cc:device:arduino:1 id  parent 0/0xd34670 upnp: 0 <0x2b92d000>

    01	02/22/15 12:11:04.302	LuImplementation::StartLua running startup code for 37 I_Arduino1.xml failed <0x2c261680>
    

    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!

    @cdrum it is recommended to use ethernet gateway with UI above 5
    you also can downgrade to UI5 to have no issues with serial gateway



  • @cdrum I tried with many arduino nano purchased on ebay but I could not connect on vera.

    Try with gateway Ethernet !!!

  • 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?? Select the mysensors profile. Then reload luup.pls note Sometimes it takes a few retrys. And doesn't always detect serial connection just be persistent. Option 2 when you get it working create a complete vera backup on your phone or pc. restore backup when needed



  • Failing that delete the mysensor gateway. Then reinstall D_Arduino1.xml. Re-add nodes as per usual.



  • Just read that link above lol. Could of saved me alot of writing on a phone. Good luck

    @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 😞



  • 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

    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)

Looks like your connection to MySensors Forum was lost, please wait while we try to reconnect.
