Hi again,

Would you mind if I ask you another question?

We have to write our program (wich communicates with the Mote Network) in VB.net, so we are about to code some kind of message listener in .net. Now we're hanging in decoding / encoding our messages. In particular, building the checksum (which we think are the last 2 bytes before the "ending" (7E)). Could you give us a few tips about the algorithm? Could you also give us a little insight what Bytes 1 to 10 (0 = "beginning" (7E)) mean? (We think that Bytes 3 and 4 are the destination address, Byte 7 the count of the payload bytes + checksum and Byte 9 is eventually the AM Type, but the other ones we don't know.)

Many Thanks...

TEP 113 (Serial Communication) describes the packet format.
