Asynchronous Bluetooth Library for Android
https://github.com/giladHaimov/BTWizBTWiz is an internal library that I have developed for several Android and Bluetooth projects. It is used by multiple teams worldwide to save time and handle errors when kickstarting a new Bluetooth project.
I designed BTWiz with the following in mind: simplicity, correctness, and asynchronicity. It makes the Bluetooth initial wiring much simpler to code, makes correct logic easier and incorrect logic harder to write, and allows simple yet robust asynchronous activation of Bluetooth commands. Firstly, it checks if the device supports Bluetooth. Then, it starts device detection by querying the paired device list to see if the desired device is already known before performing full-blown discovery. It provides the correct default (SECURE) when connecting to another device and allows users to select non-secure communication. BTWiz uses a highly effective fall-through mechanism that solves many Bluetooth connection problems.
