Updated firmware to 1.93, can't connect.

I'm using Chromium on the PC.

Could you just try installing standard Chrome and trying a normal Web Bluetooth connection from https://www.espruino.com/ide/ on it? That could be your problem - I found Chromium tended to be several versions behind normal Chrome, at least on Ubuntu-based systems.

Strange -- I don't see it.

See the attached, from https://www.espruino.com/ide/. Maybe you could look in the developer options and see if any errors are logged?

Firefox didn't work on Android

Ahh, yes - it doesn't support Web Bluetooth (yet)... It's only Chrome and Opera

Interestingly enough, if I go to Communications on espruino-server, I don't see an option for Connect over Bluetooth Smart (Web Bluetooth)

Something's really broken, it's there on mine - do you see any errors on the developer console in the browser?

Do you think any further debugging is useful at this point?

Well, if you can try the above stuff, but otherwise I guess it's best to exchange it. Where are you based?

Ideally you'd have another PC or something you could try it on though. I imagine there are probably far less than 100 people using Bluetooth LE on Arch linux in the world :)
