Hi, What you define in tinyos thru the "PFLAGS += -DTOSH_DATA_LENGTH=x" in the Makefile, it's just the MAX payload length accepted. If (some of) your actual messages will be smaller than that, you'll transmit over-the-air less than the MAX length. However, this flag will affect the memory consumption of the mote, because the buffer is pre-allocated at compile time.
Always rebember to add that PFLAGS both on your application and basestation Makefiles.
