Blue Chat

Blue Chat allows you to send text messages, files between two Android-powered, Bluetooth-equipped devices via Bluetooth connection. Whether be in an open-space office and wanting to invite your colleagues for lunch. Or chatting, sharing files with your family or housemates without leaving your bedroom. Then Blue Chat is a handy little tool for you.

Limitation:
* Not available for Android 4.2+ yet as the underlying Bluetooth component is a complete rewrite and still very unstable.
