[Tinyos-help] 29 byte message portion of a packet

[Chad Metcalf]

There is a short and very very long answer to your question.

Short: Yes... you can have multiple readings a packet but your other
assertions are not correct (29 is not a fixed size, there is packet
overhead, etc).

This is a fairly fundamental concept... so that leads me to the long answer.

Long: Read the documentation.

The message_t TEP: http://www.tinyos.net/tinyos-2.x/doc/html/tep111.html

The mote communications tutorial:

The TinyOS Programming Guide:

The example applications in the TinyOS source trees (example
MultihopOscilloscope in TinyOS 2).
