Hi, I am new to TinyOS and I am trying to change the values for CCA backoff timers. From tep126, I have learned that I can change InitialBackoff and CongestionBackoff. Then looking in CC2420CsmaP.nc and RadioBackoff.nc what I have understood is that values should be changed through requestInitialBackoff event. My question is that what command returns these events, like SplitControl.start() returns the event SplitControl.startDone(error_t error).
Secondly I would like to ask that calling setInitialBackoff(backoffTime); will change the value, but backoffTime is unspecified unit how to calculate it in term of milli seconds or any know term and what is the default value for backoffTime in initialBackoff and congenstionBackoff. Lastly if you can guide me to a sample program where Backoff timer changes are implemented it will be really nice. I would really appreciate your help.
