Bluetooth serial

[yerl...@gmail.com]

Hi,
I need to build a simple app for android and I was considering Flutter for this.
The UI is simple just four buttons with arrow icons.
Now, the app needs to connect to an Arduino board with Bluetooth serial interface like what this plugin does for Cordova (https://github.com/don/BluetoothSerial).
Is it possible yet?
Thanks.

Hi! Thanks for reaching out. I, too, want to do exactly this, so I'm curious how to do it :)

If you know how to do this from Java on Android, you can write the Arduino interface in Java, and then connect to it from Dart. We have an example of talking from Dart to Java and back here:

   https://github.com/flutter/flutter/tree/master/examples/hello_android

There's some early documentation for how to talk from Java to Dart and back here:

   http://docs.flutter.io/flutter/services/HostMessages-class.html

We are working on something similar for iOS, that's not quite ready yet though.

Thanks for the example. I already built my stuff in Cordova, but will have a look at it for the future project.

It's been a while, but I was wondering if there have been any improvements to implementing bluetooth in an flutter app

[Eric Seidel]

Well, the hello_android example from before has since been renamed to
hello_services and gained ios support:
https://github.com/flutter/flutter/tree/master/examples/hello_services

However there is still no pre-built bluetooth example that I'm aware of.

Thanks for the reply! Great job on the second dart summit! You inspired me to try flutter last year during after your first presentation, and now I'm in love with dart and really trying to using dart wherever I can. Just wanted to know that you've inspired someone :)
