Hi Rich,

The CumulusMX log can be usefull (there is no need to enable the Cumulus debug log option), however you should keep the system running until it loses connection.
From your CumulusMX log, I only can see a CumulusMX complain about a file with a invalid value:

Code:

2018-01-01 14:15:22.321 Error at line 1 of data\Dec17log.txt : Value cannot be null. Parameter name: input 2018-01-01 14:15:22.321 Please edit the file to correct the error

Don't know if this error can cause any problem.
For testing you could try starting CumulusMX (on the test PC) by firts cleanning all files in the data and backup folders.

Maybe I'm wrong but I have a feeling that the problem is not with the Nano, but something else. I saw, that you have the realtime upload set to 30 seconds, have you checked that the ftp upload to your server occours without any problem?

Thank you

Hi Werk

I was playing about with the Rpi3 and my RX unit this evening and one thing I've noticed is that the display stops updating the data that it should be receiving from the TX unit outside when I have got the USB cable connected between the Rpi3 and the RX. As soon as I disconnect the USB cable the display updates the windspeed and outside temperature values on the display. Please note that at this point the Cumulus MX software was not running.

I have now tried about four different cables this evening and it has made no difference. I'm not really sure what I should be checking next but I have a feeling that this may have something to do with it.

Kind regards
Chris
