The idea of writing this tutorial came from the discussion on Reddit recently. A young man was struggling to make things work. He was combing through various blogs and tutorials which are mostly written in Java but could not port the code to Kotlin.

I did use the Bluetooth to transfer data for one of my old applications also using Java, so I’ve decided to pull the code from the said app and convert if to Kotlin.
