我正在尝试使用我的三星 Gear S2 扫描 Sensorberg BLE 信标。我想txpowerlvl通过阅读广告数据来获得。我在 Gear S2 上使用带有更新固件的 Tizen Studio。
扫描有时会检测到txpowerlvl但有时会产生零结果（即txpowerlvlis null）。我试图从我的 iPhone 模拟 Beacon 信号，它可以检测到它们，但txpowerlvl始终为空。
我认为 Bluez 或其 API 存在问题。有些人在CSR 蓝牙板方面取得了成功，但为什么它不适用于我的 Sensorberg 信标（或我的 iPhone）？
这是我的 main.js
var BLEconnect = document.getElementById("BLEconnect");
var BLEstopscan = document.getElementById("BLEstopscan");
var BLEdisconnect = document.getElementById("BLEdisconnect");
var remoteDevice = null;
var adapter = tizen.bluetooth.getLEAdapter();
var myhandler1 = function () {
function connectFail(error)
{
console.log("Failed to connect to device: " + e.message);
}
function connectSuccess()
{
console.log("Connected to device");
}
function showGATTService(service, indent)
{
if (indent === undefined)
{
indent = "";
}
console.log(indent + "Service " + service.uuid + ". Has " + service.characteristics.length
+ " characteristics and " + service.services.length + " sub-services.");
for (var i = 0; i < service.services.length; i++)
{
showGATTService(service.services[i], indent + " ");
}
}
function onDeviceFound(device)
{
if (remoteDevice === null)
{
remoteDevice = device;
console.log("Found device name: " + device.name + " txpowerlevel: " + device.txpowerlevel + " . Connecting...");
device.connect(function connectSuccess()
{
console.log("Connected to device");
var i = 0, service = null;
var serviceUUIDs = remoteDevice.uuids;
console.log("remoteDevice.uuids: "+ serviceUUIDs);
console.log("remoteDevice.uuids.length :"+ serviceUUIDs.length);
for (i; i < serviceUUIDs.length; i++)
{
service = remoteDevice.getService(serviceUUIDs[i]);
showGATTService(service);
}
} , connectFail);
}
adapter.stopScan();
}
adapter.startScan(onDeviceFound);
}
var myhandler2 = function () {
remoteDevice.disconnect();
}
var myhandler3 = function () {
adapter.stopScan()
}
BLEconnect.addEventListener("click", myhandler1, false);
BLEdisconnect.addEventListener("click", myhandler2, false);
BLEstopscan.addEventListener("click", myhandler3, false);
window.onload = function() {
document.addEventListener('tizenhwkey', function(e) {
if (e.keyName === "back") {
try {
tizen.application.getCurrentApplication().exit();
} catch (ignore) {}
}
});
这是我的 sdb dblog
