I'm trying to scan a Sensorberg BLE beacon with my Samsung Gear S2. I would like to get the txpowerlvl by reading the advertisement data. I'm using Tizen Studio with updated firmware on my Gear S2.
The scan sometimes detects the txpowerlvl but sometimes produces zero results (the txpowerlvl is null). I have tried to simulate Beacon signals from my iPhone and it could detect them, but the txpowerlvl is always null.
I presume there is a problem with Bluez or its API. Some have had success with CSR bluetooth boards, but why doesn't it work with my Sensorberg beacon (or my iPhone)?
This is my 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) {}
}
});
This is my sdb dblog
