【问题描述】:
我一直在尝试使用 chrome.bluetoothLowEnergy API 通过 BLE 将 iPhone 5 连接到 OSX Chrome(版本 38.0.2096.0 dev)。
我在我的 iPhone 上使用BLE Utility 来模拟电池服务。我可以使用其他手机或OSX utility 发现该服务并连接到它,但我在使用 chrome 时遇到了问题。我可以看到我的设备已列出,但未发现任何服务,当我尝试连接到该设备时,连接失败并显示以下消息:
操作失败
如果有任何帮助,我将不胜感激。
这是我的代码:
manifest.json

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

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);
