Setting RF power tinyos (telosb)

Question

I'm working on a project where I have increase or decrease the RF power based on rssi value. The sender mote sends data and the receiver measures the rssi value.

Based on that, I have to set the power of antenna. How can I achieve that?

Thank you

Answer 1

That's probably a little late answer, but this might help others, so here it is:

You can either change it in code by calling:
call CC2420Packet.SetRFPower(&packet, pwr);

or by changing it at compile time in Makefile by adding this line:
CFLAGS += "-DCC2420_DEF_RFPOWER=N"

where valid values for pwr in setRFPower and N in CFLAG are 1 through 31 with power of 1 equal to -25dBm and 31 equal to max power (0dBm).
