You can change the output power level in two ways: (1) per packet or
(2) once for all at the compile time (e.g., CFLAGS +=
-DCC2420_DEF_RFPOWER=11). Please serach in TinyOS archives for "Output
Power levels of CC2420."
You also mention about changing receive power. Do you mean changing the
Carrier Sense threshold ? I am not sure how to do this.
However, if you mean changing the receiver power, to the best of my
knowledge, power consumption in
receiving a packet can not be changed. Nevertheless, radio can be
switched into sleep mode (please remember that in sleep mode, radio does
not sense traffic).
