.Net MAUI app using Plugin.BLE for Polar H10 Heart Rate Sensor. Bluetooth LE working solution on Android.
52 stars 12 forks source link

Code will only run on Android. Fails on iOS. #2

Open jdg3k92 opened 2 years ago

jdg3k92 commented 2 years ago

I had downloaded your sample application which show cases Plugin.BLE for Maui. (very neat, clean, well written)

Below is my experience with trying to run the application on a Mac in iOS Simulator (and tethered too). Maybe you can provide some guiadance....maybe not. Maui is very new and I am looking at it as a replacement for our Aging Xamarin forms application which is completely dependenty on Cross-Platform BLE support.

Thanks.

Steps to reproduce

  1. Install Visual Studio 2022 for Mac (17.3.7)

  2. Clone THIS repo and open in VS.

  3. Build and run on ios simulator

Expected behavior

The App should load and display the landing page in iOS Simulator (Works fine for Android Simulator and Real Android device)

Actual behavior

code blows up and throws exception. Main message is the following:

This functionality is not implemented in the portable version of this assembly. You should reference the NuGet package from your main application project in order to reference the platform-specific implementation.

Hej

Sorry, no help from me. I don’t own iPhone or Mac. Android works. I am waiting .Net MAUI to mature.

I want to build an app for Android, iOS and Windows using .Net MAUI and Bluetooth LE and only Android is working so far.

Timo,

Thanks. You’ve done a great job so far. I think you are right; Maui is not yet what it needs to be. However, you should stay on top of this because many people are going to be looking for a solution to this problem. I’ll keep an eye on your repo for updates.

This problem should be fixed by updating Plugin.BLE to 3.0.0-beta.1. @jdg3k92, can you confirm that?

TimoKinnunen commented 1 year ago

I can not confirm that Plugin.BLE 3.0.0-beta.1 will find Bluetooth LE on Windows. Plugin.BLE 3.0.0-beta.1 is better though than Plugin.BLE, no exception is thrown on Windows. Android emulator and Android smartphone is ok. iOS is not tested on my behalf.

janusw commented 1 year ago

I can not confirm that Plugin.BLE 3.0.0-beta.1 will find Bluetooth LE on Windows.

Well, yeah, beta.1 does not fix everything on Windows yet, but the exception on iOS (as reported above) should be gone. I will push a beta.2 release soon with further fixes for Windows.

TimoKinnunen commented 1 year ago

It sounds nice. Good work.

jdg3k92 commented 1 year ago

Thanks. I’ll try it out soon

Using PackageReference Include="Plugin.BLE" Version="3.0.0-beta.2": On Windows for example this does not work IReadOnlyList systemDevices = Adapter.GetSystemConnectedOrPairedDevices(HeartRateUuids.HeartRateServiceUuids); Result is systemDevices = 0; The good thing is no exceptions.

See the comment at https://github.com/dotnet-bluetooth-le/dotnet-bluetooth-le/blob/f474528254bf227dc984477a9367aa088d17c301/Source/Plugin.BLE/Windows/Adapter.cs#L137-L143:

            //currently no way to retrieve paired and connected devices on windows without using an
            //async method.

Seems this is a limitation of the current implementation for Windows. One would have to check the Windows APIs to see if there is a way to implement this. Please open a new issue in dotnet-bluetooth-le.

TimoKinnunen commented 1 year ago

You are right this is inside current implementation for Windows. And therefore a question for James Montemagno, I think. But how to reach James?

I don't think it's a question for James in particular. As I said, please open an issue for this. You can mention James, if you think it helps.

Hi! I found this repository while googling for examples to work with Bluetooth LE in MAUI. I see here was no activity for 9 months. Does the latest beta work with ios? Or are there any recommendations how to use Bluetooth with ios too?

TimoKinnunen commented 1 year ago

Hello

My activity has been Microsoft Blazor lately and now image object detection.

The state of mentioned repository is what it was 9 months ago.

Hey @jdg3k92 - I just did quick fixes for iOS and it worked perfectly.

Good work. I program a Blazor web app for now and .net Maui sleeps.
