I want metro style app Bluetooth Low Energy Health Profiles sample can access Thermometer Health Service installed in Bluetooth Low Energy (LE) Generic Attribute (GATT) Profile Drivers. However, I encountered 80070005 (E_ACCESSDENIED) while Health Profile Metro App trying to access device.

The error is in Thermometer.js. deviceFactory.getDeviceFromIdAsync returns error 80070005 .

            done(function (devices) {
                // If devices were found, proceed with initialization
                if (devices.length > 0) {
                    try {

                        // Use WPD Automation to initialize the device objects
                        var deviceFactory = new ActiveXObject("PortableDeviceAutomation.Factory");

                        var devServiceName = document.getElementById('deviceServiceName' + Constants.thermometerDeviceShortName);
                        devServiceName.innerText = devices[0].name;

                        // For the purpose of this sample we will initialize the first device
                        deviceFactory.getDeviceFromIdAsync(devices[0].id, function (device) {

                            // Initialize the temperature service
                            tempService = device.services[0];

                            // Set up ApplicationActivated to be called asynchronously (fire-and-forget mode)
                            tempService.onApplicationActivatedComplete = function() {};

                            // Set up ApplicationSuspended to be called asynchronously (fire-and-forget mode)
                            tempService.onApplicationSuspendedComplete = function() {};

                            var devs = DeviceData.getDevices();
                            var devId = Constants.thermometerDeviceIndex;
                            devs[devId] = {
                                devId: devId,
                                name: devices[0].name,
                                description: devices[0].id,
                                data: [],
                                handler: function (timestamp, thermometerMeasurementValue) {
                                    try {
                                        var measuredValue = {
                                            timestamp: new Date(timestamp * 1000),
                                            value: thermometerMeasurementValue,
                                            toString: function () {
                                                return this.value + " \u00B0C @ " + this.timestamp;
                                            },
                                        };

                                        DeviceData.addValue(
                                            Constants.thermometerDeviceIndex,
                                            measuredValue);

                                        if (uiVisible) {
                                            UIHelper.updateUI(Constants.thermometerDeviceShortName, Constants.thermometerDeviceIndex, measuredValue);
                                        }
                                    } catch (exception) {
                                        WinJS.log && WinJS.log(exception.toString(), "sample", "error");
                                    }
                                }
                            };

                            tempService.onTemperatureMeasurement = devs[devId].handler;
                            tempInitialized = true;
                            UIHelper.refreshUI(Constants.thermometerDeviceShortName, Constants.thermometerDeviceIndex);
                            tempService.ApplicationActivated();

                        }, function (errorCode) {
                            WinJS.log && WinJS.log("Getting the device failed with error: " + errorCode.toString(16), "sample", "error");
                        });

                    } catch (exception) {
                        WinJS.log && WinJS.log(exception.toString(), "sample", "error");
                    }

I've followed the instructions in Forum post Why access denied (80070005) when I run Metro Simple bluetooth LE Controller using TICC2540 Dev kit in Win8 release preview. I created the Device Metadata Package on my local Win8 64bit Desktop, but I still encounter error 80070005 (E_ACCESSDENIED). 

Are the following values wrong for Bluetooth Low Energy Health Profiles sample ?
I have remove the Bluetooth Low Energy device and reinstall again, and reboot again, but I still has 80070005 error.

Have you enabled test signing and rebooted?

I have launched Command Prompt(Admin) console window, run "bcdedit /set testsigning on", and then reboot Win8 Desktop PC. I found "Test Mode" showing in the bottom right corner of desktop.
However I still encounter error 80070005 in
Thermometer.js. deviceFactory.getDeviceFromIdAsync().

Uncheck the "Access Custom Driver" box in the Device Metadata Authoring Wizard and redeploy the metadata. This box is only intended for custom WDF drivers accessed via IDeviceIoControl.
