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.
