Many thanks for that..... you are of course right, I had forgotten to close the VP1 switch. Out of interest, does VP1 = Virtual Port 1? Apart from this error, everything worked first time.
I'll post some photos later tonight. I was building for a while yesterday and need to go out and get some fresh air today
Thanks again for a great design.

First of all, congratulations for having built the system very quickly.
The issue you describe, can happen for two reasons:
The first one, and I bet on this: After programing Arduino, and before starting Cumulus, you forget to close the VP1 switch.
Second one: Even with VP1 on close position, after a restart, you must wait 2 to 3 minutes before attempting to connect Cumulus.
Everytime you need to reprogram the Arduino, you must revert VP1 switch to open position, and after programing close it again.
Please report back.
Do you have any pictures of your system?
