Simple cross-platform BluetoothLE library for Xamarin.Forms

triaxis.bluetoothle's Issues

Add usage documentation, possibly simple example application

Hi,
Is there a way you can add an application to solution so that I know which API's to call?

IServiceCollection' does not contain a definition for 'AddBluetoothLE'

Trying to build the DeviceBrowser example app. Running into this error:

Error CS1061 'IServiceCollection' does not contain a definition for 'AddBluetoothLE' and no accessible extension method 'AddBluetoothLE' accepting a first argument of type 'IServiceCollection' could be found (are you missing a using directive or an assembly reference?) DeviceBrowser (net6.0-windows10.0.19041.0)

I tried both adding the Nuget package or including a Project Reference to the 'triaxis.BluetoothLE.Maui' project. Both methods gave me this error.

Using VS2022 17.5.1

Any help would be appreciated.

Sample?

A sample MAUI project on how to use this would be great:)

Unable to load assembly

I'm trying to get this to work under Maui (Preview 14). The assembly throws an exception while trying to create an instance.

System.NotSupportedException: 'Cannot create instance of type 'triaxis.Maui.BluetoothLE.Android.StateBroadcastReceiver': no Java peer type found.'

Has anyone gotten this module to work in .NET MAUI Preview 14?

No Scan Result in Example App (DeviceBrowser)

Tested the example app on Android but there is no result for the scan.

MAUI -- Me Too Movement???

Just chiming in to voice my support for Maui.... Where can documentation be found?

Exception unhandled

triaxis.BluetoothLE.BluetoothLEException: 'Connection lost: Success'

Any suggestion on how can I handle this? It happens when BLE device is turned off when connected.
