Clicker Battery By BlueTooth

Hi,
I'm trying to read battery level from the clicker, but it seems, unsuccessfully...

I'm using the microsoft example from here:
https://docs.microsoft.com/pt-pt/windows/uwp/devices-sensors/gatt-scenarios

and because I can run UWP async methods on Unity, I created a Task running on the background, reading the battery level every xxx minutes...

var devices = await DeviceInformation.FindAllAsync(GattDeviceService.GetDeviceSelectorFromUuid(GattServiceUuids.Battery));

var service = await GattDeviceService.FromIdAsync(devices[0].Id);

var clickerCharacteristic = service.GetCharacteristics(GattCharacteristicUuids.BatteryLevel)[0];

var BatteryLevel = await clickerCharacteristic.ReadValueAsync();

byte levelData = Windows.Storage.Streams.DataReader.FromBuffer(BatteryLevel.Value).ReadByte();

UpdateClickerBattery((double)levelData);

I also enabled the Capability on the Manifest:

<DeviceCapability Name="bluetooth.genericAttributeProfile">
<Device Id="any">
<Function Type="name:genericAccess" />
</Device>
</DeviceCapability>

And always get the same value [ 71 ] .
I tryed to charge the clicker, a still give 71 % of battery...

I also already checked that the service is the "Clicker" service, because if I print the devices[0].Name it will return "Clicker"....

Any help would be very appreciated...

Cheers.

 

Thanks for your help,

but I already try that....

My callback " batteryLevelChanged" is never called...

But I was guessing that the callback is not being called because I'm running in a thread , not in the Unity main thread...

Because I can't ( don't now how to ) run async methods from the main thread, I'm lauching it in a separate thread...

ClickerBatteryTask = Task.Factory.StartNew( () => GetClickerBatteryLevelForEver() );

In this case my method " GetClickerBatteryLevelForEver " is the "Initialize" from the example.

And the callback is never called....
But maybe because the callback is defined on the main thread...

I will try passing the object as argument of the thread, so see if the callback is called...

Like This:

ClickerBatteryTask= Task.Factory.StartNew( () => GetClickerBatteryLevelForEver(this) );

And then :

private async void GetClickerBatteryLevelForEver( PowerManager pm )
{
{.......}

batteryLevelCharacteristic.ValueChanged += pm.batteryLevelChanged;

{.......}
}
