Attempting to run a very basic script:

const poweredUP = new PoweredUP.PoweredUP();

poweredUP.on("discover", async (hub) => { // Wait to discover a Hub
    console.log(`Discovered ${hub.name}!`);
    await hub.connect();
    const motorA = await hub.waitForDeviceAtPort("A");
    console.log("Connected");
    console.log(motorA);
    console.log(hub);
});

Results in this error:

Node.js v18.13.0

Alright, so what if I require that package explicitly:

F:\Code\twitch-train-control>npm install bluetooth-hci-socket

added 4 packages, and audited 14 packages in 5s

found 0 vulnerabilities

Running the code again gives me the exact same error as above, though, so no changes if I try this.

package.json after this:

{
  "dependencies": {
    "bluetooth-hci-socket": "^0.5.1",
    "node-poweredup": "^8.0.5"
  }
}

I can provide the lockfile if required.

I feel like I'm missing something but I do not have enough experience with JS packages to work that out. I'm happy to run debugging commands if you let me know what other output would be useful.

I've technically solved this by moving the bluetooth-hci-socket folder in node_modules into the @abandonware folder, and this has fixed it, though I feel like that's not a recommended solution...

@abandonware/bluetooth-hci-socket is pulled by @abandonware/noble, and not by node-poweredup. The package is in optional-dependency section there and recently added to normal dependencies https://github.com/noble/noble/commit/29166df77354275801b5018e9dd5553d258acef5 and then removed again https://github.com/noble/noble/commit/6c84903a586c3deb442417daaf7618ea2557a551

In my setup (linux, oder npm version) the dependency is installed together with node-poweredup. Not sure if the dependency should indeed be optional there, if it would now need to be explicitly requested by node-poweredup and why the behavior is different in different npm versions.

Can you have a look in package.lock file what version of @abandonware/noble you are getting and what happens if you install @abandonware/noble directly?

I think it might be this bug https://github.com/npm/cli/issues/4828
