Master Emulator Scan Response Packet

That did the trick! I got DiscoverDevices confused with StartDeviceDiscovery. What is the difference between the two?

Where did you set the scan parameters? Active scanning should be enabled in the StartScan() function like this:

BtScanParameters scanParams = new BtScanParameters();
scanParams.ScanType = BtScanType.ActiveScanning;
success = masterEmulator.StartDeviceDiscovery(scanParams);

I have not made any other changes. Are you sure that your ManufacturerSpecificData is in the Scan Response packet?

Have you done any other changes to the example? I tested it here, and it works just fine.

My device does advertise a CompleteLocalName. With the added code the ManufacturerSpecificData is not displayed in the log field.

Do your device advertise CompleteLocalName or ShortenedLocalName? If not, the onDeviceDiscovered function will return after the first if-setting. Can you try this code, to see if the ManufacturerSpecificData is displayed in the log field?

void OnDeviceDiscovered(object sender, ValueEventArgs<BtDevice> e)
{
	this.BeginInvoke((MethodInvoker)delegate()
	{
		dgvDeviceDiscovery.Enabled = true;
		dgvDeviceDiscovery.Visible = true;

		BtDevice dev = e.Value;
		string deviceName = "";
		IDictionary<DeviceInfoType, string> deviceInfo = dev.DeviceInfo;
		if(deviceInfo.ContainsKey(DeviceInfoType.ManufacturerSpecificData))
		{
			log.Add(new StringValue(deviceInfo[DeviceInfoType.ManufacturerSpecificData]));
		}
		if (deviceInfo.ContainsKey(DeviceInfoType.CompleteLocalName))
		{
			deviceName = deviceInfo[DeviceInfoType.CompleteLocalName];
		}
		else if (deviceInfo.ContainsKey(DeviceInfoType.ShortenedLocalName))
		{
			deviceName = deviceInfo[DeviceInfoType.ShortenedLocalName];
		}
		else
		{
			return;
		}

		string key = deviceName + " (adr: " + dev.DeviceAddress + ")";
		discoveredDevicesList[key] = dev;
		dgvDeviceDiscovery.RowCount = discoveredDevicesList.Count;

	});
}

I also tested it with the HealthThermoDemo, and it works fine here. Can you upload your OnDeviceDiscovered() function?

That is what I do, but I don't get anything. I can see the data in nRF Connect and I can even do that same procedure in a different example, "proximity demo," but I can't see it "HealthThermoDemo."

Hi,

If you only have Manufacturer Specific Data in scan response, you should be able to access it like this (will print the raw MSD to log field):

if(deviceInfo.ContainsKey(DeviceInfoType.ManufacturerSpecificData))
{
    log.Add(new StringValue(deviceInfo[DeviceInfoType.ManufacturerSpecificData]));
}

Best regards,

Jørgen
