Android Question Problem by recieving a text via bluetooth with AsyncStreams

Hello,

i am using the Android Bluetooth / BluetoothAdmin Tutorial to connect my android device with my laptop. To recieve and send files at my laptop i am using the terminal program "HTerm". It works to build a bluetooth connection and i can also send a text from my android device to my laptop. But always if i try to send a text from the terminal program to my device the "Sub AStream_Error" is called instead of "Sub AStream_NewData".
If i use the Android Serial tutorial and recieve a text via the TextReader it works.

Does anyone knows how to fix this problem?

Thanks for your help!
