B4R Library rCurieBLE - Arduino 101 BLE

With this library it is simple to connect to the Arduino 101 board with an Android or iOS device.
Arduino 101 instructions: https://www.b4x.com/android/forum/posts/448783/

It is similar to B4i peripheral implementation: BLE (Bluetooth Low Energy) Peripheral

It creates a service (0001) with a readable characteristic (1001) and a writable characteristic (1002).

The NewData event is raised when a central device, the iOS or Android device, writes to the writable character.
The DataAvailable event on the central device is raised after a call to CuriePeripheral.Write.

Note that messages are limited to 20 bytes. Don't try to send more as it will break the connection.

A B4A + B4R example is attached.

Thank you

Are you running the B4A program in debug mode? I don't think that you are seeing the program logs. You might need to switch to USB debug mode instead of B4A-Bridge.

It looks like you are still using B4A-Bridge.
Make sure that B4A-Bridge is disconnected (bottom left corner):
