Master Emulator Scan Response Packet

[Andrew]

How do I get data from a scan response packet using master emulator?

I do know about

BtScanParameters scanParams = new BtScanParameters();
scanParams.ScanType = BtScanType.ActiveScanning;

But this doesn't seem to be enough.

I am working off of the example code from the "HealthThermoDemo" I want to access the ManufacturerSpecificData from a scan response packet so that I can use that data to add to the list of available devices in the OnDeviceDiscovered function.

What do I need to do?

(Note: the ManufacturerSpecificData is only in scan response packet not in both places so I don't have to worry about this)

Edit: This is my OnDeviceDiscovered() function:

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.CompleteLocalName))
                {
                    deviceName = deviceInfo[DeviceInfoType.CompleteLocalName];
                }
                else if (deviceInfo.ContainsKey(DeviceInfoType.ShortenedLocalName))
                {
                    deviceName = deviceInfo[DeviceInfoType.ShortenedLocalName];
                }
                else
                {
                    return;
                }

                string manufData = "";
                if (deviceInfo.ContainsKey(DeviceInfoType.ManufacturerSpecificData))
                {
                    manufData = deviceInfo[DeviceInfoType.ManufacturerSpecificData];
                }


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

            });
        }

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

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."

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

[Jørgen Holmefjord]

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;

	});
}

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