[Tinyos-help] Radio Tx power control

[Jon Charnas]

Hi everyone,
I've looked over the mailing lists and as much documentation as I could, 
but I can't seem to find out how to access the micaz's ability to 
modulate the radio transmit power. I'm using TinyOS 2.0 (latest on the 
liveCD), and most of the posts and documents I've seen pertain to 1.x, 
using the POT interface.
I just came across this commit log,
http://mail.millennium.berkeley.edu/pipermail/tinyos-2-commits/2005-January/000016.html, 
which seems to indicate I can define the power level using a
#define TOS_DEF_RFPOWER  statement, but I don't know what the range of 
values it expects is, nor could I find where it is originally declared.
And, if at all possible, I was really interested in varying the power 
levels during operation (meaning not resetting the mote, but it changes 
periodically).
Thank you very much,
Jon
