... I think it's the component that sits between the USB port and the end of the CH340 controller.

Yes, its that component (black with white trace in one of the sides).


Before the radical step of removing the Nano from a Pro2 v6 board, may I sugest that you try to running the system with exactly the same version of CumulusMX but running on a PC, just to check if the USB connection will break.

Is the PI3 executing any other tasks than running CumulusMX?

You may also try to add this parameter to your Cumulus.ini file in the Station section:

Code:

VP2SleepInterval=1500

Hi Werk

I'll dig out my old Windows laptop and setup CumulusMX on it and see what happens. The PI3 is running as a headless system purely for connectivity to the RX board so I'm not running any other tasks on it. 

Before I do that I will try adding that parameter to the Cumulus.ini file and see what happens.

One thing I've noticed is that when Cumulus appears to stop getting data from the RX unit the LCD display connected to the RX board doesn't update either. However when disconnected from the Pi3 the LCD display starts updating again.

Kind regards
