所以我尝试用一些代码测试蓝牙连接。每当我尝试扫描蓝牙设备时，我没有弹出窗口来允许它，所以它一直在等待。我知道代码工作，因为我们是在组中工作，它在我的合作伙伴的MacOS电脑上工作，但在我的Windows上不工作。我主要希望它扫描带有BLE的ESP。我已经启用了"实验性的网络平台功能“和”使用新的权限后端网络蓝牙“标志，并确保我的Chrome更新，并确保蓝牙扫描和设备的权限启用。

console.log("Init");

document.getElementById("scan").onclick = scan;
navigator.bluetooth.addEventListener("advertisementreceived", (event) => {
  console.log("Advertisement", event);
});

async function scanDevices() {
  const devices = await navigator.bluetooth.getDevices();
  console.log(devices);
}

async function scan() {
  console.log("Scanning...");
  let options = {
    acceptAllAdvertisements: true,
  };

  try {
    log("Requesting Bluetooth Scan with options: " + JSON.stringify(options));
    const scan = await navigator.bluetooth.requestLEScan(options);

    log("Scan started with:");
    log(" acceptAllAdvertisements: " + scan.acceptAllAdvertisements);
    log(" active: " + scan.active);
    log(" keepRepeatedDevices: " + scan.keepRepeatedDevices);
    log(" filters: " + JSON.stringify(scan.filters));

    navigator.bluetooth.addEventListener("advertisementreceived", (event) => {
      log("Advertisement received.");
      log("  Device Name: " + event.device.name);
      log("  Device ID: " + event.device.id);
      log("  RSSI: " + event.rssi);
      log("  TX Power: " + event.txPower);
      log("  UUIDs: " + event.uuids);
      event.manufacturerData.forEach((valueDataView, key) => {
        logDataView("Manufacturer", key, valueDataView);
      });
      event.serviceData.forEach((valueDataView, key) => {
        logDataView("Service", key, valueDataView);
      });
    });

    setTimeout(stopScan, 10000);

    function stopScan() {
      console.log("Scan result", scan);
      log("Stopping scan...");
      scan.stop();
      log("Stopped.  scan.active = " + scan.active);
    }
  } catch (error) {
    log("Argh! " + error);
  }
}

function log(c) {
  console.log(c);
