How to Interface with Windows Universal App ?

Hi Gordon ,
I was able to get all the data from puck using the advertising example of Microsoft.
Microsoft provides a class BluetoothLEManufacturerData were you can get the CompanyId and the data. To make Microsoft's example to work I had to comment all the filters(this class takes filters to limit the bluetooth devices) and that resulted to return me everything..

https://msdn.microsoft.com/en-us/library­/windows/apps/windows.devices.bluetooth.­advertisement.bluetoothlemanufacturerdat­a?f=255&MSPPError=-2147217396

The thing is that I want to limit (add filter) the number of devices and read only the puck devices.
I was wondering how to do that.

The class has a CompanyID property and the Data. When you put the CompanyID as a filter the watcher reads only this device. Take a look at the below code .

        // Begin of watcher configuration. Configure the advertisement filter to look for the data advertised by the publisher 
        // in Scenario 2 or 4. You need to run Scenario 2 on another Windows platform within proximity of this one for Scenario 1 to 
        // take effect. The APIs shown in this Scenario are designed to operate only if the App is in the foreground. For background
        // watcher operation, please refer to Scenario 3.

        // Please comment out this following section (watcher configuration) if you want to remove all filters. By not specifying
        // any filters, all advertisements received will be notified to the App through the event handler. You should comment out the following
        // section if you do not have another Windows platform to run Scenario 2 alongside Scenario 1 or if you want to scan for 
        // all LE advertisements around you.

        // For determining the filter restrictions programatically across APIs, use the following properties:
        //      MinSamplingInterval, MaxSamplingInterval, MinOutOfRangeTimeout, MaxOutOfRangeTimeout

        // Part 1A: Configuring the advertisement filter to watch for a particular advertisement payload

        // First, let create a manufacturer data section we wanted to match for. These are the same as the one 
        // created in Scenario 2 and 4.
        var manufacturerData = new BluetoothLEManufacturerData();

        // Then, set the company ID for the manufacturer data. Here we picked an unused value: 0xFFFE
        **manufacturerData.CompanyId = 0xFFFE;**


        // Finally set the data payload within the manufacturer-specific section
        // Here, use a 16-bit UUID: 0x1234 -> {0x34, 0x12} (little-endian)
        var writer = new DataWriter();
        writer.WriteUInt16(0x1234);

        // Make sure that the buffer length can fit within an advertisement payload. Otherwise you will get an exception.
        manufacturerData.Data = writer.DetachBuffer();

        // Add the manufacturer data to the advertisement filter on the watcher:
        watcher.AdvertisementFilter.Advertisemen­t.ManufacturerData.Add(manufacturerData)­;


        // Part 1B: Configuring the signal strength filter for proximity scenarios

        // Configure the signal strength filter to only propagate events when in-range
        // Please adjust these values if you cannot receive any advertisement 
        // Set the in-range threshold to -70dBm. This means advertisements with RSSI >= -70dBm 
        // will start to be considered "in-range".
        watcher.SignalStrengthFilter.InRangeThre­sholdInDBm = -70;

        // Set the out-of-range threshold to -75dBm (give some buffer). Used in conjunction with OutOfRangeTimeout
        // to determine when an advertisement is no longer considered "in-range"
        watcher.SignalStrengthFilter.OutOfRangeT­hresholdInDBm = -75;

        // Set the out-of-range timeout to be 2 seconds. Used in conjunction with OutOfRangeThresholdInDBm
        // to determine when an advertisement is no longer considered "in-range"
        watcher.SignalStrengthFilter.OutOfRangeT­imeout = TimeSpan.FromMilliseconds(2000);

        // By default, the sampling interval is set to zero, which means there is no sampling and all
        // the advertisement received is returned in the Received event

        // End of watcher configuration. There is no need to comment out any code beyond this point.

The example puts a value manufacturerData.CompanyId = 0xFFFE;
In our case with the Puck device what should I put in order to tell the watcher to read only the puck.js?
Is this value changes everytime ?

Appreciate your guidance on this.

thank you
