The tale of two nanos

Sadly I don't think it is Ch340, it identify's as a FT232R. It has taken the sketch, the display part is work just no hand shake, is there perhaps a different USB serial library I could try?

If there is following code line inside of setup(), try to comment it out.
while (!Serial);
change to
// while (!Serial);

Hi SStaub thanks for that suggestion.

Sadly that has no effect, regardless as to whether I force it to use USBSerial or just Serial.

It looks like a driver problem.

Thanks sstaub, just wanted to share this. The working nano is identifying as CH340 so clearly I must have installed those drivers for another project at some point. The nano that isn't handshaking with EOS identifies at RT232R USB UART. I have installed, the latest RT232R drivers but it is still behaving the same. being detected as a USB device but no handshake.

other than one change to the Display Rotation the sketch is identical, the only other difference is the CH340 uploads using ATmega328p and the RT232R won't but will if I change to ATmega328p (Old Bootloader)

Maybe there is a conflict with the USB drivers installed by Nomad.

Excellent thought, will try another installation of nomad on another PC.

Update, you were right, a fresh install on a Mac and the none working Nano works just fine. So it must have been a windows driver issue. Will investigate when I have a mo.

Fine, Nomad and the Arduino IDE install different FTDI drivers.
