Hello,
I'm working with tinyOS-2.x under Ubuntu and I'm trying to measure the RSSI
using telosb motes with the interface ReadRssi and I've programmed a java
application that shows directly the RSSI value taken from the tinyOS
application RssiToSerial and the value when there isn't activity in the radio
channel is about 78. What does this mean? What is the real Rssi value taken ?
Is directly the RSSI.RSSI_VAL register from the cc2420? I thik the response of
this last question is affirmative. Therefore I've programmed a java class to
convert this value from 2's complement to normal binary with 8 bits, but I
don't trust their correct working . Can someone explain me how to interpret the
real Rssi value in dB's or dBm from this readings? I would be very grateful
for an example to explain me.
Thanks in advance.
