The code is finding my device but how do i pair the device? This is snip of the code I have: private async void DeviceWatcher_AddedAsync(DeviceWatcher sender, DeviceInformation args) { if (args.Name == "DeviceName") { if (args.Pairing.CanPair && !args.Pairing.IsPaired) { device = args; } } } My args.Pairing.CanPair is true, and my args.Pairing.IsPaired is false. My question is how do i make the IsPaired to true? Thanks!

Thank you, Great explanation, but last Principle is still not clear for me

Great. Thx!

Incorrect, bluez was already at version 5.6 in 2021. (this is also the problem i'm having... system says its the last version but it is not!)

I subscribed and thumbed up because I like this and found it useful. But I should say that it's wrong to call an "app registration" a "service principal" because although creating a service principal will create an app registration, the reverse is not true. An app registration can exist without an app principal, but not the other way around. And although a service principal is an instance of an app registration with its own object id, client id, etc. and assigned roles through RBAC, a service principal has additional qualities like credentials that allow it to auth requests to Azure resources.

Congrats for this great Tutorial!!! Comments about the process shown at 46:43 Configure Build Pipeline to use GitVersion to generate Semantic Version For people following this in 2024 with the AZ native Agent there are some slight changes due the facts that the current agent does not have the .Net core SDK 3.1 installed. As Core 3.1 was wiped out time ago you only get .net SDK 6/7/8 pre-installed. Updated Steps: # Install NetSdk 3.1 to use the GitVersion extension - task: UseDotNet@2 name: 'InstallNetCoreSdkForGitVersion' displayName: 'Install .NET Core Sdk 3.1.0 for GitVersion' condition: succeeded() inputs: version: '3.1.x' includePreviewVersions: false # Setup git fake user & defaultBranch - task: CmdLine@2 displayName: Init git global config condition: succeeded() inputs: script: | git config --global user.email "EMAIL-OF-PIPELINE-USER" git config --global user.name "Pipeline_Build_Staging" git config --global init.defaultBranch main # Enable Git commands using this account - checkout: self displayName: 'Checkout Self' fetchDepth: '0' persistCredentials: true # Config gitversion 5.3.x # github.com/GitTools/GitVersion - task: gitversion/setup@1 displayName: 'Setup git version' inputs: versionSpec: '5.3.x' condition: succeeded() # Calculate the version of source code - task: gitversion/execute@1 displayName: 'Calculate SemVer' inputs: useConfigFile: true configFilePath: 'GitVersion.yml' condition: succeeded() # Print in console current version in the format x.y.z ó 3.0.1 - script: echo current version is $(GitVersion.SemVer) displayName: 'Display calculated version' condition: succeeded() NOTE: On the task to Setup git fake user & defaultBranch you can specify anything as user and email including fake data ;)

Thanks for this very cool video. This was just what I needed to get started 😊

Little to no explanation of anything here. Not really a "How to" video. Going through a bunch of git commands and muttering, "let's see, I'll do such and such and that looks good..." is not a "how to" video.

Excellent. information i am getting exception line number 80 WriteClientCharacteristicConfigurationDescriptorAsync could you help on this if i use WriteClientCharacteristicConfigurationDescriptorWithResultAsync status is protocolerror 0x03

Can you please tell how to migrate this code from console .Net framework to WPF.

Very useful, thank you. I was able to use this to write a small app to connect to a GoPro Hero 12 via Bluetooth, get the AP name and password then enable the WiFi AP. The only real change I had to make from your code was to add in the addition of a protocol selector when creating the Device Watcher. Until I did that I wasn't able to reliably pair every time or read and write to the camera. I got that from a C# example on the OpenGoPo repo. I also added the Microsoft.Windows.SDK.Contracts Nuget package as mentioned below too. string BLESelector = "System.Devices.Aep.ProtocolId:=\"{bb7bb05e-5972-42b5-94fc-76eaa7084d49}\""; DeviceInformationKind deviceInformationKind = DeviceInformationKind.AssociationEndpoint; string[] requiredProperties = { "System.Devices.Aep.Bluetooth.Le.IsConnectable", "System.Devices.Aep.IsConnected" }; DeviceWatcher deviceWatcher = DeviceInformation.CreateWatcher(BLESelector, requiredProperties, deviceInformationKind);

Awesome, thank you very much for your tutorial. Very enlightening. I missed a part with the "writing" capabilities of this.

what are the prerequisites to know before diving in?, Is this systems programming, hardware or network programming?, I would like to know how to fish

Great video Cornel. Planning to use my new found knowledge to read a bluetooth temperature module. Thanks a lot. I have liked and subscribed.

Thanks

If you are not able to add "using Windows.Devices" then here is a solution: stackoverflow.com/questions/37496244/desktop-c-sharp-referencing-windows-devices

thanks! i added some write function in your code so i was able to test BLE module byte by byte in handler I was a bit confused when I first referenced it, but it seems to work fine in the end. I simply checked the received value of 1 byte sent, but now I think I can operate it continuously.

Very helpful video. Please make more videos on Azure :)

thank you very much.

The first C# bluetooth video that really works... Thank you!

Unbelievable this video has just ~30 likes. Tremendous work behind. To me it has been very useful. Congrats for the author!

Hi! I want to read the heart rate value from my Xiaomi band 4 using a Raspberry PI4. I've already connected and paired the band with the raspberry using bluetoothctl, however when I try to read, notify, write... characteristics or services I got the message: Unable to read attribute. I don't really know why, I followed all the steps carefully. Can anyone give me hand? :) Thank you in advance!!!!

First, Thanks for the tutorial, this helps me to build my app. But I found some problems while coding further, so I share the solution here, may help someone else later Cornel Human is using devicewatcher, with this, it will be very hard to find your device if you turn on it later than your app start, and also has problem to reconnect device if your device goes out of range and back into range later. The solution is to use bluetoothleadvertisementwatcher instead of devicewatcher, just couple lines modifition

Hello Cornel, The 2 references you added, Wndows.WinMD and system.runtime.windowsruntime. I dont have those in my paths you have mentioned. Can you explain on how to get them?

Very informative. Thanks for the video. I am using your code to connect with our Nonin 3230 oximeter but its not reading, condition for GattCharacteristicProperties.Notify never met true. Can you please help us on this. 🙏

Thank you for tutorial. Helped a lot!

Very useful, thanks

Thank you. This healped

I can't really read the code you are working with. Do you share it for download??

If you're looking for how to do the merge conflict in the Azure Devops PR UI, this video only shows it in the typical local GIT branch conflict resolution method.

You are an absolute BEAST. Thank you so much for this tutorial!

Hi your videos are great and helpful, we are working on a wahoo kickr fan which will increase the speed of the wind according to the speed of the trainer or heart rate. i want to write the values on it using trainer speed, unfortunately the values shown are these "Press any key to pair with fan Pairing with the device..... Pairing successful..... 00001800-0000-1000-8000-00805f9b34fb 00001801-0000-1000-8000-00805f9b34fb 0000180a-0000-1000-8000-00805f9b34fb a026ee01-0a7d-4ab3-97fa-f1500f9feb8b a026ee0c-0a7d-4ab3-97fa-f1500f9feb8b Press any key to exit app" and i think these values are only i have read the gatt service documentation on bluetooth website and could you help me telling what will be the name documentation for it like the trainer is "fitness machine" i cannot figure out what are the characteristic to write-on. or can you tell us which properties or flags are write-able. can please you help me or give me an idea how to do it.

i landed on this video after spending entire day to understand these concepts.. you nailed it.. thanks man

Great video .... I am searching for login using active directory user/pwd also create user api

Will this work/be as easy for Mac? Have a master task on the university and I have to connect the wahoo kickr core to my Mac (programming in python)

Tu

Instead of all the references you could also add the Microsoft.Windows.SDK.Contracts Nuget package.

Nice Video! I was looking for a DIY solution to control my Kickr Core as I don't need Zwift. I'm just looking for a solution to set resistance and to go trough my training scheme.

I found this helpful - thanks

Thanks for the video, it was very informative. i do have one question about SemVer though. If you have to tag the repository in order for SemVer to calculate the correct version why not just use the gittag for your docker tag instead of running SemVer ?

Hello, we are working on a wahoo with Kickr Climb. Your code and example works like a champ. But we are trying to setup the tilt value for the Wahoo Kick Climb without success... please can you help us?

you made my day 😀

Thank you very much, it worked all very fine! Now I have a question: I have a self built device with 5 characteristics I can subscribe to (gyro, force, etc). After i subscribe to one of them i would like to unsubscribe from it and subscribe to another. I can remove the listener on my .net client, but i realized that my device still sends the data I subscribed in the first place. Is there a way to tell it to stop sending data? Thanks a lot!

you're a legend! Showing the process was extremely helpful; like showing the process and then showing the documentation because this is my first time making anything with c#. Thanks for the video!

Great Video Cornel. Thanks for sharing. Any idea how to maintain a connection with a device that has dropped out or turned off/on again? Cheers

I tried this same method to connect to huwavei fit 2. Its showing ,if (result.Status == GattCommunicationStatus.Success), showing result.Status as unreachable

nice and great video, it truly helps me to understand to how to call restapi to Azure resources. can you post the postman queries you showed in the demo? it is hard to see and type from videos.

How to find my TICKR? THANKS

God damn, it took me an hour and a half to get as far as 3:38.

Hey just wanted to say thanks for this video, this was exactly what I needed. Maybe it's a bit niche to get a tons of views but it helped me out. Great to see clear explanations and I really appreciate you citing and pointing out the docs you used to find things instead of just pasting in magic device UUIDs too.
