It's run. Thank you 
I think it was the bitwise operation

No, because the function Float Speed = Float.intBitsToFloat(bits);
needs as parameter a integer value.
Integer is in Java 4byte and Float 4byte too.
Are the packets right?

Outgauge Packet - Java
Hello,
i'm programming my own Outgauge Tool in Java.
I take the Outgauge UDP Packet and want to get the 4 Speed Bytes (12 - 15). After that i use a bitshifter to convert this 4 bytes into float.
But the float is totally wrong with the values.
Can anybody see my fault?
Here is the code:

When is "early in 2009" ?
It seems as if someone cannot wait any longer for the new version. So he has programmed his owen counter.
