Hi Glyn
The module was purchased from openevse in the US a few weeks ago, the one there is on the way right now is just a backup.
I was working until I tried to update it.
I have tried to erase the flash as you suggested.

Found 3 serial ports
Serial port COM7

Erasing flash (this may take a while)...
