PeerToPeerBle

This is an example project showing how to configure Android devices as both a BLE client (central) and BLE server (peripheral). This project is meant to accompany a talk I gave at DroidKaigi 2020.

Use Case

This sample projects demonstrates a one-off BLE connection where two Android devices, both acting as a client and a server, come into contact with each other, exchange some data, then disconnect. However, with minor changes, the implementation shown here can be altered to fit any use case.
