我正在尝试使用Samsung Gear S2扫描一个Sensorberg BLE信标。我想通过阅读广告数据来获得txpowerlvl。我在Gear S2上使用Tizen Studio和更新的固件。
扫描有时会检测txpowerlvl，但有时会产生零结果（txpowerlvl为null）。我试图模拟来自iPhone的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。有些人使用CSR bluetooth boards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
