Upload fails

Hi,

I tried to upload some code to a ArduinoBT-Board, but everytime I try the Arduino IDE shows me the following message:

Binary sketch size: 4038 bytes (of a 28672 byte maximum) avrdude: stk500_getsync(): not in sync: resp=0x34 avrdude: stk500_disable(): protocol error, expect=0x14, resp=0x38

I already tried it with different computers and also I tried to press the reset-Button on the board. What makes me wondering is the 0x34. Most posts I found dealing with upload-problems tell about the same message with resp=0x00. Is this something that can hint to the error?

Thanks Nick

No one any idea?
