nRF UART Bridge app can be used to connect to Bluetooth® Smart devices running a custom Nordic Semiconductor UART service. When connected, the app bridges the UART port with TCP port, so an Android device can be used as a BLE interface over WiFi or USB.

This source code can be compiled with Android Studio and Gradle.

Based on Android-nRF-UART app by Nordic Semiconductor.
