i have port the example to a UNO like the example code.
Connection is made and the Android device show the millis send from UnO.

Pressing the LED-Button on the Android breaks the communication !
No data arrived the UNO, the Timer-event was fired but no data arrived the android.

After pressing the RESET-Button , sending works again.

The same with a DUE works without problems.

Which pin is connected to the button? Which pins are connected to the Bluetooth module?
Pin 10 and 11 are connected to the Bluetooth-Module,
the pin-Button is not connected (try only the receiving data)

Add log messages to see whether AStream_NewData is raised or not. Try to send a single byte from the Android.
In the meantime i have changed to the actual B4R-Version,
and wonder, NOW it works directly :)) ????
