btleplug VS ndk

In case someone is curious: https://github.com/deviceplug/btleplug/pull/279/files

Is something wrong with https://github.com/deviceplug/btleplug or you haven't found it? You could also use bindings to platform libraries like https://github.com/microsoft/windows-rs and https://github.com/rust-mobile/ndk if btleplug doesn't have something fundamental to you.

One of the worst/best parts of buttplug is that I ended up needed to maintain my own Bluetooth LE library: btleplug (https://github.com/deviceplug/btleplug).

Worst because working with bluetooth is always THE WORST, best because of the submissions and community that've grown around it.

There's 2 types of PRs to btleplug:

- People going "here's a PR but uh, why is the library named btleplWAIT WHAT"

- People going "here is a PR specifically to fix something in Buttplug thank you"

"In its dev branch"

I've always been annoyed at the cross-platform story for Bluetooth. GATT is one of my favorite protocols because it is so simple, but writing simple code against this simple protocol is _not_ portable:

iOS and macOS have CoreBluetooth, Linux has BlueZ, Windows has Windows.Devices.Bluetooth and Android has android.bluetooth.

I've seen a few projects trying to fix this, like https://github.com/deviceplug/btleplug, and I hope one of them becomes production ready.

But, that's an ongoing problem. In terms of "done", I think the next big milestone will be mobile app support. We work on mobile web browsers in a couple of different ways, but Buttplug still needs app support, both native and for things like cordova/react native/etc... The biggest issue there at the moment lies in our bluetooth library (btleplug, https://github.com/deviceplug/btleplug), because getting the FFI via JNI to android is going to suck (even though I can crib off Servo's WebBluetooth impl, which worked on Android).

You can already. The ndk allows any language to be compiled to android. For rust see

https://github.com/rust-mobile/ndk

Which has the tools to do this.

I found an official introduction to the topic: https://source.android.com/docs/setup/build/rust/building-rust-modules/overview I found these bindings and even tried to make the examples work without luck: https://github.com/rust-mobile/ndk There even exists an interface with the C++ library I am using: https://docs.rs/oboe/latest/oboe/

There's cargo-apk which is godsent extension making the process of building an apk as easy as cargo apk build. Although I wasn't able to make it fully work on my native machine, so I used miniquad's docker image, installed cargo-apk, and then built.
