Bluetooth Low Energy support? #948

Open Ellerbach opened 4 years ago

Ellerbach commented 4 years ago

Some devices are connected using Bluetooth Low Energy (BLE). This is supported in Xamarin for example on the diverse platforms. Is there any plan to have similar support for .NET Core?

krwq commented 4 years ago

We haven't considered this during planning. Do we have any sense on how much work that is?

shaggygi commented 4 years ago

Seems like it would follow similar pattern as System.Device.Gpio (and protocols - SPI, I2C, etc.) like Windows.Devices.Bluetooth... System.Device.Bluetooth? Should this be a separate package as it most likely wouldn't need dependencies on current GPIO stuff?

krwq commented 4 years ago

I'd start with putting this in Iot.Device.Bindings bag for a starter and once it's stable enough either put it in System.Device.Gpio or new package

Ellerbach commented 4 years ago

@krwq, I don't know exactly how much work it will require. Looking at some part of Xamarin and couple of additional packages, it's quite some work. BLE seems to have quite some specificities with contracts and services, the mechanism needs to be implemented quite low level on my understanding and then there will be the possibility to add capabilities for specific sensors like buttons, like temperature, some integrated portable devices, etc. This clearly needs more research. And yes, probably for a new phase. But I see more and more sensors integrating this capability to be wireless and low consumption.

For the Linux side, there is a .net library in development at https://github.com/hashtagchris/DotNet-BlueZ.

There is a lot of abstraction work in Windows.Devices.Bluetooth which could be taken as an example, but the platform-specific implementation would then still need to be made.

hansmbakker commented 3 years ago

There is also work in https://github.com/nexussays/BLE.net for other platforms

danielmeza commented 3 years ago

@hansmbakker DotNet-BlueZ is a good library for build BLE Clients apps. I have already implemented an server app using dbus to implement BlueZ also. But before to use bluez as a solution on Linux systems, we need to include dbus support on .net core, currently we had Tmds.DBus implementation on .net core but it not below to any foundation and will be great if we include that first on .net core as a dbus implementation. If not, we need to make another abstraction layer.

I had a brief conversation with the fellow MVP Peter Foot @inthehand about bluetooth support. He is working on BT (classic and low-energy) support in .NET and he already implemented the fundamental parts (see https://github.com/inthehand/32feet).

Once it's completed, it would be interesting creating a layer in our library to abstract devices behind BT.

Fantastic news @inthehand and @raffaeler ! What would be even better is to have the API aligned with the .NET nanoFramework implementation as we already have quite some people using it: https://github.com/nanoframework/nanoFramework.Device.Bluetooth We already have SPI, GPIO, I2C, Serial aligned ;-) And this time, it's first on nano. So IoT should align with it.

what's the current status of this implementation?

raffaeler commented 1 month ago

@inthehand Peter, could you please provide some news about the work you were doing in this space? Thanks!
