I am newish to Flutter and know no other languages. I am wanting to develop an app that will run on Android, iOS, web, Windows etc. The app is require to read (and hopefully write as well) BLE. Initially just from the Waterrower (www.waterrower.com) but hopefully in the future from other rowers as well. The Waterrower has a bluetooth addon (Commodule) which appears to not be very reliable. https://github.com/inonoob/pirowflo is developing a Pi based unit which is yet to come on the market but looks very promising. Coxswain is a waterrower app that only works on Android that is written in Java, can uses bluetooth and can also uses a USB cable for direct serial connection. There are a few Flutter BLE libraries (flutter_blue, flutter_bluetooth_serial (based on flutter_blue), flutter_reactive_ble) but they are only for Android and iOS. There is github.com/tbressler/waterrower-core written in Java for connecting the waterrower with Windows, Linux and macOS. I have no idea how the app running in a browser would connect to BLE.
