问题描述

我一直在尝试一个iPhone 5使用了API chrome.bluetoothLowEnergy BLE连接到OSX浏览器（版本38.0.2096.0 DEV）。

我使用的我iphone模拟电池服务。我能发现该服务并使用其他手机或 OSX效用，但我有镀铬这样的问题。我可以看到我列出的设备，但没有发现服务，当我尝试连接到该设备，连接失败，出现以下消息：

  "description": "Chrome BLE Test",
  "version": "1",
  "app": {
    "background": {
      "scripts": ["background.js"]
    }
  },
  "bluetooth": {
    "low_energy": true,
    "uuids": ["180f"]
  }
}

script.js

function main() {
  var onGetServicesCallback = function(services) {
    if (chrome.runtime.lastError) {
      console.log(chrome.runtime.lastError.message);
      return;
    }

    console.log('Services:', services.length);

    if (!services) {
      console.log('No services');
      return;
    }

    services.forEach(function(service) {
      console.log(service);
    });
  }

  chrome.bluetooth.getDevices(function(devices) {
    if (chrome.runtime.lastError) {
      console.log(chrome.runtime.lastError.message);
      return;
    }
    console.log('Found devices:', devices.length);

    if (devices) {
      devices.forEach(function(device) {
        console.log('Device name:', device.name);
        chrome.bluetoothLowEnergy.getServices(device.address, onGetServicesCallback);

        chrome.bluetoothLowEnergy.connect(device.address, function() {
          if (chrome.runtime.lastError) {
            console.log('Connection failed:', chrome.runtime.lastError.message);
            return;
          }
          console.log('Connected!');
        });
      });
    }
  });
}

document.addEventListener('DOMContentLoaded', main);

解决方案

The BLE implementation for the Mac is not complete yet as far as I know. A good place to follow the development of the API is on the Chrome issue tracker. This is a link to the issue related to the Mac one specifically. To see all the bluetooth changes, just search for bluetooth under open issues.
