- Wed Jul 08, 2015 7:19 pm #22804 I've got a web server running just fine on the v.9 board. But, when I try to run the same code on the v1.0 board it doesn't work. I'm using the Expressif SDK v1.1.1 which seems to flash with no errors. But, when I upload my web server (the example Web server that comes with the IDE) I get some weird characters in the serial monitor (normal) but the Code doesn't seem to run. Any suggestions?

Here's the board I can't seem to get to work.

It works when I flash it with the Lua-included SDK but I can't get my C code to run. There are no errors, it just doesn't work.

That wasn't in the earlier IDE releases but in the newer ones you should have menu option Tools -> Board -> NodeMCU 1.0. Do you see that and are you using it?

Editing boards.txt didn't work for me so I ended up adding a board definition using the boards manager. The board definition here worked like a charm.

I'm running v1.6.5 of the IDE and it didn't contain the nodeMCU defintions.

thanks for sharing

BTW I followed your option 2

and added both xml to File->Boards->Preferences->additional boards manager
