Hi Philip
Just to understand the behavior of TOSSIM i was curious why sendDone () is called after receive() at source, or may be receiveDone() shd also be included in future versions of TOSSIM.


Take a look at how far apart the two are in time. It should be microseconds. This is well within simple code execution time differences. If it happens to be that the receiver samples a bit before the end of the bit transmission time, then the reception interrupt might occur slightly before the transmit interrupt. Note this is particular to how the software stack for a mica node is implemented.
