Ok, the thing is that it cannot put the whole message into the serial message payload, so the last field (which is the array) is omitted. You need 3.5 bytes for "rx", 4.5 for 13817759, 2.5 for 55952, 1.5 for 0, 1.5 for 17 and 18.5 for the 17 byte payload. That adds up to 32 bytes but the payload of the message is 28 bytes at most. Add the following define to the sniffer application makefile: TOSH_DATA_LENGTH=40, that will fix your problem and show the proper payload.
