B4R Question HC-05 example with UNO

[newbie]

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.

You need to use a level shifter as the HC 05 expects 3.3 volts.

I am using a HC-06 , but the tech-data are the same.
I have try a level shifter like this

it seems not to be the problem,
with and without shifter the reaction is the same !?

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.
