Had a problem when uploading the Led example with can not find Python.exe I must have forgotten to tick the add to paths box although it was installed by Platform IO this time after I did a OS reinstall.
EDIT: I had to allow Python.exe through my firewall and the Arduino sketch I tried came up with No answer. Used a dedicated Esp8266 one and it uploaded.
Worked once and the Nodemcu is no longer found and not showing up on my hub manager; oh well when I can work up some enthusiasmI will have another go
