Hello,

I have problem on reading LQI and RSSI values from a iris mote. In one
of my application I was using RSSI and LQI values. I used to use
shimmer motes with tinyos. Both of LQI values were provided in
CC2420Packet interface with the functions of getRssi and getLqi. But
now I am trying to use same application on a iris motes from crossbow.
But I am not able to find the same interface or any interface
suggesting LQI and RSSI values. I found variables as strength and lqi
on TOS_MsgPtr. But these provides numbers in a different(ie. LQI in
shimmer (50,100), LQI in iris (0,255)) range than before. Is there any
conversion formula from one to another or should I read these values
from somewhere else on iris.

Thanks in advance...
