This Android app provides a line-oriented terminal / console for Bluetooth LE (4.x) devices implementing a custom serial profile For an overview on Android BLE communication see Android Bluetooth LEOverview.

This app includes UUIDs for widely used serial profiles:

• Nordic Semiconductor nRF51822

• Texas Instruments CC254x

• Microchip RN4870/1

• Telit Bluemod

• Filtering, scanning, linking, reading, writing, notification subscription and cancellation in a simple way.

• Support custom scan rules

• Support multi device connections

• Support configuration timeout for conncet or operation

• A device's location services can use Bluetooth to detect Bluetooth beacons and provide a more accurate location
• In Android 11 or lower, individual apps require location permissions to use BLE scanning
• From Android 12, the BLUETOOTH_SCAN, BLUETOOTH_ADVERTISE, and BLUETOOTH_CONNECT permissions can allow apps to scan for nearby devices without needing to request the location permission. For more information, see New Bluetooth permissions in Android 12.
• My BLE library work on Android 5.0+ (API level 21+) .
