What happened?

I was going through README.md as I was interested to learn about Windows 10 IoT Core and use it for my project.When I clicked on "Get Started" it redirected to Error 404 - "Sorry, we couldn't find that page."

What you expect to happen?

I expected to be taken to "Get Started" guide of Windows 10 IoT Core.

Reference:

In README.md under the first paragraph of Windows 10 IoT Core samples in the Note section go to line 5 : Get Started.

When I try to build the serialuart project I get the error Cannot resolve Assembly: System.Private.Networking version 4.0

What is this and how do I add it or get it in the right place, I am on Win 10 64, do I even need it can I comment out something if it doesn't have anything to do with the serial communications.
Thanks

The pictures on the README.md of https://github.com/Microsoft/Windows-iotcore-samples/blob/develop/Samples/IoTStartApp/Cpp/README.md show up as broken icons.

On the frontpage (https://github.com/Microsoft/Windows-iotcore-samples) the link to IoT Onboarding is invalid. It points to:https://github.com/Microsoft/Windows-iotcore-samples/blob/develop/Samples/IotOnboarding

When clicking the link you end up at:

Hi,
The links of the Apps are all missing.

Previously there were a sample and article on HID injection using the virtual hid framework, but they have either not been migrated or have been removed.

What is the reason for their removal? Could you please update them and put them back online?

DeviceIoController should be deleted.

Will you make the IoT Core project templates available for VS2019?

I'm asking the question here since the original repo is archived.

Hi,is there any way to turn on/off monitor on iotcore?thanks

Hello, I am trying to use the WifiConnector sample to connect to a network that uses EAP-TLS with client and root certificates. In your readme you say that if the certificates are installed on the machine already that just clicking "Connect" will work.

"For networks that support Extensible Authentication Protocol (EAP), also known as Enterprise WiFi authentication, a password checkbox will be shown. If your enterprise network device is configured with the required certificates, you can simply click Connect."

This is not working for me through the sample app unfortunately. It currently works when i use the Windows 10 built in wireless manager, but not the sample application. Do you know what else is required in the WifiConnector app to be able to connect to these networks? How does the built in manager do it? With the native wifi APIs you could specify in the profile which certificate to use, but I see no way with the WinRT APIs to do this.

Thank you for your help.

Will there be any samples of a Cortana enabled IoT Core app that people who are interested in this stuff can try out. we are more interested in what Cortana can do within the IoT realm.

Hi,

I am using below code base for one of the project implementation-
https://github.com/microsoft/Windows-iotcore-samples/tree/develop/Samples/EdgeModules/SerialWin32/CS

I have to handle one scenario where in case USB cable got disconnected, how to handle that-

If i disconnect USB cable and connect it back. I didn't see any response and any exception. I need to implement the scenario if we connect the cable again it should handle that-

// Start Async Read, using overlapped structure
device.Read(inbuf, size, out numbytes, ref overlapped);
Log.WriteLineVerbose($"Async Read {i} Started");

// Block until Read finishes
device.GetOverlappedResult(ref overlapped, out numbytes, true);

Is it blocking call, that's why it is not coming out from here.

Can you please help me how to handle this case.

Thanks

Hi,
According to the steps here, all works fine. But why the diagnostic tools can't be used when debugging?

I try to do the HelloWorld sample but while setting up Visual Studion and the project, I am not able to find or install the Windows IoT Extensions for the UWP.
In the list where I can add references I can only find the Windows moble Extensions for the UWP but not for IoT.

I'm reporting issue to not your repository but your repository will never look well till "Microsoft/OpenCV" issues will not be solved. Please look at guide by link
https://github.com/Microsoft/Windows-iotcore-samples/tree/develop/Samples/OpenCVExample/CPP
It reference other link
https://github.com/Microsoft/opencv/tree/vs2015-samples
I you documentation you say "Download Microsoft's fork of the OpenCV library". You say download because "git clone" doesn't work
microsoft/opencv#83
Then look, for example I decided to use Windows IoT and OpenCV in my production solution on x84 and ARM architecture. You should provide the sample to mix it in the best way. We are happy that you evolve Windows-iotcore-samples but you have dependency to abandoned "Microsoft/opencv" repository and attaching dependent dll files in very bed way because you add dll files only for particular architecture. You are working in cook company that has MSBuild and lots of professionals so you should provide sample with good approach of linking OpenCV.
Microsoft is one company and both repositories "Microsoft/Windows-iotcore-samples " and "Microsoft/OpenCV" should look well. Please, try to ping the responsible man for "Microsoft/OpenCV" because only you may do this.
I also have created an issue microsoft/opencv#82
But I think that their issue is also issue of your repository.
We hope you will be able to manage this. Thank you.

About: Windows-iotcore-samples/Samples/RGBLED/

README: "Connect the cathode (the longest leg) of the Tri-color LED to Pin 6 GND."

I'm using a Raspberry 3B+. Where does the led get its power from?

I've connected the longest leg to 3.3V (not to GND) and then it sort of works. But (example) the blue led goes ON when I use ".Low"

redpin.Write(GpioPinValue.High);
greenpin.Write(GpioPinValue.High);
bluepin.Write(GpioPinValue.Low);

I'm using this in a Windows 10 IoT Background Service and when the program is not running the RGB led shines a little bit of blue light. When I set all the pins to HIGH, when the program runs, the led turns completely off.

This sample code works fine on Raspberri Pi 3 with Windows 10 IOT but failing when ran on DragonBoard 410C

serialPort = await SerialDevice.FromIdAsync(dis[0].Id)

returns null although dis[0].Id has some data in it.

Hello,

We are trying to use Windows IOT in Time Critical Application using Controller Area Network(CAN/J1939). I couldn't find any example which can receive data at a minimal periodicity of 10msec and interrupts being enabled. Can any one help us out on this, We are using Interl Atom processor.

We've leveraged the capability of ProcessLauncher. Seems to work fine on some devices. On some others, we get an UnauthorizedAccessException. Details below:

So far we've tested on 3 different devices. Each running an 1809 version of IoT Core. 2 boxes, the process launcher works. 1 box it doesn't. Interestingly, the box that it doesn't work on is the most recently setup device (flashed with IoT Core).

In looking at the folder permissions in the location the app is installed, it appears there is a difference between the boxes this works on and the one it doesn't.

The SerialUART sample seems to fail on a R-Pi3 using internal on board UART

The internal UART that comes with the Rasberry PI3 which is Enumerated as device ID '\?\ACPI#BCM2836#0#{86e0d1e0-8089-11d0-9ce4-08003e301f73}' using DeviceInformation.FindAllAsync()
Causes an exception when atempting to get the SerialPort via SerialDevice.FromIdAsync()

Value does not fall within the expected range.

Spent a few days trying to get this going, and then found adding this to the manifest fixed the issue.

  <Device Id="any">
    <Function Type="name:serialPort" />
  </Device>
</DeviceCapability>

It did work for about a week, and then, as per other reports of people also suggesting it was 'intermittent' I now not being able to get it working again after a further few days.

After a bit more research I found this artical that suggest on-chassis UART are not supported
https://docs.microsoft.com/en-us/uwp/api/Windows.Devices.SerialCommunication

And that they should be filtered out of FindAllAsync() enumerations.

My question is, what is the reason for this? Is it an issue with the handling of the onboard Broadcom UART? Is there plans to fix this? As after spending alot of time on this, seems a waste that the on-board UART cant be used!

Thanks!

Seems Serial UART got deleted as may have been duplicate, but seems Both SerialUART and CustomSerialDeviceAccess have both been removed? Is this intenttional?

#153

Also 'SerialUART' seems worthy of a separate project amongst the notable others, as its a very common device for most IoT projects.

Hi,

After loading your project on VS, the IDE doesn't seem to recognize the line: using System;
After redading google results, it seems that this namespace belongs to the .NET Framework.

So, do I have to update the .NET Framework on my computer even if it is preinstalled on Windows 10?

thx

On the frontpage (https://github.com/Microsoft/Windows-iotcore-samples) the link to IoT Browser is invalid. It points to: https://github.com/Microsoft/Windows-iotcore-samples/blob/develop/Samples/IotBrowser

• but vs underlines it error. why?
• I used to new other project and try it, it was ok. but in "Universial Window Project" is failed..
• how can I fix it?

Minor issue:
FORCE_OOBE_WELCOME_SCREEN macro is defined for Debug|ARM, Debug|x86, but not for Debug|x64.
It probably should be defined for all debug configs (ARM, x86, x64) or for none of them.

There is a customer report that SerialUART sample not working on Windows 10 Pro (Version 10.0.17134). SerialDevice.FromIdAsync(dis[0].Id) always returns null. He use the following device:

dis[0].Id = "\\\\?\\FTDIBUS#VID_0403+PID_6001+A906I45PA#0000#{86e0d1e0-8089-11d0-9ce4-08003e301f73}"

But he get it working on Raspberry Pi 3B+.

So is this issue related to Windows edition Pro?

MSDN thread: https://social.msdn.microsoft.com/Forums/en-US/980892e7-2b29-4c30-904b-9d885b74c9d7/serialport-await-serialdevicefromidasyncdis0id-returns-null?forum=WindowsIoT

Just tried with 17692 and updated to 10.0.17704.1000
and dont think this is fixed. Same issue with finding UART device ID "\?\ACPI#BCM2836#0#{86e0d1e0-8089-11d0-9ce4-08003e301f73}"

But SerialDevice.FromIdAsync(serialDeviceFound.Id) // ID above

still has exception

"Value does not fall within the expected range."

still have below in manifest

SerialUART is a duplicate of https://github.com/Microsoft/Windows-iotcore-samples/tree/develop/Samples/SerialUART and should be deleted.

The documentation of opencv sample is redirected and cannot be seen from last week.
Is there any way to see that now?

Hello

I have tried to make event hubs of azure sample to windows iot core and it does not work .(The iot hub sample works fine )

Should event hubs be used in IOT core ?
Pls refer MicrosoftDocs/azure-docs#6249

"IoT Core Default App" uses the same ObservableCollection instance for keeping both incoming BT pairing requests and the BT devices located around. Every update of a BT device nearby triggers an update of the ObservableCollection instance. Updates of the ObservableCollection object remove all incoming BT pairing requests. When there are a few BT devices around, the ObservableCollection content changes too frequently. So it's getting very complicated/impossible to accept any incoming BT requests.

Rasp Pi 4B had already released since i got to know Windows 10 IoT ver. PLS figure out how it works on Pi 4, silly me even dont know how to make win10 iot work on Pi4B+

I downloaded the IoT WiFi Onboarding solution and went through all the steps in the README. I was able to successfully follow every step until Step 4.8 in which I encountered an issue.

When the OnboardingService attempts to call WifiAdapter.ScanAsync (see line), I get the following error:

Exception thrown: 'System.UnauthorizedAccessException' in System.Private.CoreLib.ni.dll
Access is denied. (Exception from HRESULT: 0x80070005 (E_ACCESSDENIED))

The stack trace is just:

at System.Runtime.CompilerServices.TaskAwaiter.ThrowForNonSuccess(Task task)

The reason I downloaded this solution is because I was getting the same error when implementing this on my own IoT Core application and this project claimed that it would get it working with a headless application. My belief is that this was never meant to work according to the docs for ScanAsync which claim that:

You should call this API from a foreground app. If it is called from a background task, you will see an "Access Denied" error message or a similar message.

The Microsoft docs for Wi-Fi onboarding list this sample as a way for connecting to a Wi-Fi network from a headless application, so I'm not sure how this sample is supposed to get around this limitation.

• Windows v.10.0.17134.285

1. Please upload 3.x source code of IoTDefaultApp.
2. Try to analyse this Language setting bug from source code:
   After setting language to Chinese(Simplified) in IotDefaultApplication's System setting page, Navigate to other page(in Hamburger Menu) and come back, the settings will be lost and language combo box displays nothing. What's more, With setting system language to Chinese(Simplified), Multilingual applications including Simplified Chinese language still runs like an en-us application, no zh-CN words show.
   PS：IotDefaultApplication's version is 3.1.0.0

When using VS2019 Developer Command Prompt and trying to build the BusTools with

msbuild /p:Platform=ARM /p:Configuration=Release

was getting Linker error

fatal error LNK1112: module machine type 'x86' conflicts with target machine type 'ARM'

But all projects and solution seemed to have Target set correctly for ARM.
After some time found solution was that VS2019 did not have MSVC v142 - VS 2019 C++ ARM build tools (v14.21) installed via VS installer.

Personally not C++ experience much these days, is this type of issue expected, or should there be a more clearer error message indicating the ARM build tools may not be available?
As it was not clear in either CLI or VS that the /p:Platform=ARM switch was failing and falling back to using X86

I was getting an acccess denied due to invalid subscription key (Face API). But I am using the correct api key.

With the help of a colleague we found that the workaround is to add your apiroot value when calling the Face api in FacePage.xaml.cs:
FaceServiceClient f_client = new FaceServiceClient(key_face, "https://westeurope.api.cognitive.microsoft.com/face/v1.0");

SerialUART sample's C# codes hide artful bug that exists at SerialDevice class. More details below.

The bug: not all SerialDevice settings are applied after corresponding properties set. The same properties should be read before reading something from the device.

MainPage.xaml.cs has lines 94..101:
// Configure serial settings serialPort.WriteTimeout = TimeSpan.FromMilliseconds(1000); serialPort.ReadTimeout = TimeSpan.FromMilliseconds(1000); serialPort.BaudRate = 9600; serialPort.Parity = SerialParity.None; serialPort.StopBits = SerialStopBitCount.One; serialPort.DataBits = 8; serialPort.Handshake = SerialHandshake.None;

Actually, this lines has no sense without next lines 103..108:
// Display configured settings status.Text = "Serial port configured successfully: "; status.Text += serialPort.BaudRate + "-"; status.Text += serialPort.DataBits + "-"; status.Text += serialPort.Parity.ToString() + "-"; status.Text += serialPort.StopBits;

So bug may be reproduced easily by commenting lines 104..108 and using non-default settings at lines 95..101. This cause that you will never get into line 264 (if (bytesRead > 0)).

We found this bug then we tried to create own project using this sample codes with BaudRate=115200.

I think that corresponding attention note should be included in the sample before till the bug fix.

P.S.
We don't see a proper way to make bug-report except this issue and Windows Platform Developer (WPDev) Feedback voice.

I followed this sample tutorial: https://github.com/Microsoft/Windows-iotcore-samples/tree/develop/Samples/MemoryStatus/CPP .
And found that in "To create you own project" step, it is said to "select the template 'Blank Windows IoT Core Console Application'" but in the picture below show another template: "Background Application (IoT)" in the red rectangle box.

Hello, I am now developing Raspberry App on vs2017, but the samples always say missing " using System.string". Should I add reference manually?

There seems to have been a lot of moving destinations around recently.
The Windows IoT Core (https://developer.microsoft.com/en-us/windows/iot/samples)
no longer links to samples.
The path seems to have been changed from master to develop. Is this intentional?
