Bluetooth SPP with Android


Android has had Bluetooth (BT) Serial Port Profile (SPP) server and client capability since API Level 5 (version 2). Two Android devices, one acting as a server and the other as client, can communicate over BT SPP.

Bluetooth SPP Server Terminal app allows you to simulate a BT SPP peripheral. I used it recently to try and simulate a Push-To-Talk accessory for an app called Zello, running on another Android device.

Bluetooth Terminal is an open source app that can be used to create a BT SPP client connection with other devices, and exchange text and binary data.
