@suda Do you have more then one compiled firmwares (firmware_*.bin files) in your project's directory?
Where is this directory? Just where I saved the ino file? I couldn't really find a 'new project' button so I just made a new folder and saved the pasted code from the web ide in it. If that's the folder you're referring to, then no. I don't have ANY of those files.
Also, for some reason when I try to connect via the Serial Monitor window I'm getting:
Window load time: 10235ms index.js:39
Uncaught Error: Invalid port specified: undefined events.js:85
