WinRT bindings for Noble (using BLEServer.exe)

Noble (Node.js Bluetooth LE) Bindings for Windows

noble-winrt is a small UWP-to-noble bridge based on the web-bluetooth-polyfill project. It supports BLE connectivity on Windows without the need for a dongle and complicated driver set-up. It is similar to noble-uwp but may work better for some build processes.

Getting Started

Install with npm or yarn:

npm install --save noble-winrt

Then simply use in place of noble:

const noble = require('noble-winrt');

noble-winrt will perform exactly the same as noble on non-Windows systems. However, it will use the WinRT bindings on Windows instead of noble's default Bluetooth HCI bindings.

Integrating with bleat

If you'd like to use this library to work with the Web Bluetooth api through bleat, you will have to replace noble to noble-winrt. Running the following command in a powershell terminal in the directory containing your project's node_modules should take care of that:

node -e "var fs = require('fs'), `
  f = 'node_modules/bleat/dist/adapter.noble.js'; `
  fs.writeFileSync(f, fs.readFileSync(f).toString().replace(`
    'require(\'noble\')', 'require(\'noble-winrt\')'))"

noble-winrt's Issues

Requires WinUSB install?

Added this to my project and seem to have successfully installed and built all dependencies.

However, when I try to run any noble code I am hit with an error LIBUSB_ERROR_NOT_SUPPORTED

It appears that this is due to my computer not having the WinUSB driver installed: https://stackoverflow.com/questions/17350177/libusb-open-returns-libusb-error-not-supported-on-windows-7

Does this library require a USB dongle with WinUSB installed?

Can not find services

Hello i used the noble module in my Linux environment and it works very well, so i tried this one on my Window envronment but i can not find the same services of the same device...

stateChange is always poweredOn

Hi! I would like to ask if there's a way to check bluetooth state is on or off?
I try switching the windows bluetooth on and off, but it's always stay in the state of "poweredOn".
Even when i try relaunching with bluetooth state off, it's still detect as "poweredOn".

noble.on('stateChange', function(state) {
console.log(state);
if (state === 'poweredOn') {
noble.startScanning();
} else {
noble.stopScanning();
}
});

Do you have plan to port bleno (bleno-winrt)

Spawn ENOENT when running in installed Windows app

Dealing with an issue that's only popping up on Windows 10 and the release version of an electron app that's been installed into system programs.

Uncaught Error: spawn C:\Users\jdpig\AppData\Local\Programs\BrainWaves\resources\app.asar\node_modules\noble-winrt\prebuilt\BLEServer.exe ENOENT

I've confirmed that BLEServer.exe exists at that path and that the app has read/write access to that file. I've also tried running the app as administrator and using cross-spawn instead of child-process.

I see a lot of issues out there about running spawn in Node.js successfully on Windows. However, none of the provided solutions seem to be working: nodejs/node-v0.x-archive#2318
