I have a nodemcu board and I use currently the Lua firmware. I would like to try the "Arduino mode". Which firmware should I use in order to use Arduino IDE and upload sketch files?

Thank you

It should not matter, but for some reason it sometimes does. no matter what firmware you have on your module you should be able to download from Arduino. If the code doesnt execute try this viewtopic.php?f=32&t=2275&start=10#p13674
