espruino --list returns "Error: No compatible USB Bluetooth 4.0 device found!"

[TheLogan]

Hi, so I am trying to see my Bangle.js 2 on my pc, I'd rather use VS Code for development than the app, so I am playing around with commandline.
In the web ide I can connect to my bangle with the button in the top left, no issues.
But in commandline I get the following error:

undefined:55
    } else throw err;
           ^

Error: No compatible USB Bluetooth 4.0 device found!

I suspect that the culprit is bluetooth-hci-socket is in a folder called @abandonware and when I went to their page I could see that the last release was 6 years old and the last code edit was 4 years old.
So it's likely woefully outdated at this point :(

I did find this
noble/node-bluetooth-hci-socket#118
but it doesn't really seem like a viable solution, and I can't get it working for my self either.

It seems that the @abandonware project is an attempt to save orphaned projects, but it hasn't really helped this one xD
Not sure what the solution is though :/

I had the same problem, and I solved it using the issue you linked to. So edit the file in node_modules adding the values used there, and it should work.

Obviously that's not a very good solution, so maybe a PR to @abandonware could help?

Like this, right? I first tried with the values suggested in the link, and when that didn't work I downloaded zadig got the values relevant to my pc and tried again, but still didn't work.

Obviously that's not a very good solution, so maybe a PR to @abandonware could help?

If it had worked, then certainly, but ... well I at least can't get it to work xD

Moving this to the EspruinoTools repo...

I think there's a list of supported devices, and you just put your device's USB IDs here: https://github.com/abandonware/node-bluetooth-hci-socket/blob/master/lib/usb.js#L15-L30

A PR to abandonware would be great. Basically the original 'noble' was just totally abandoned so that project sprung up to try and fix the issues with it.

Either way, it's not really a great solution since it goes straight to the USB adaptor. Since Windows 10 you can just access BLE devices via API, and you'd hope there would be a node module to handle that. I'm not sure if there is though.

I did winnus but then Node.js changed their API so it doesn't build for more modern Node.js versions (and even so since then Windows released a better API that should be used instead)
