[Tinyos-help] RSSI

[roberto pagliari]

I need to know two questions regarding how the cc2420 works
1) why does in cc2420M.nc the call TOSH_READ_RADIO_CCA_PIN() does not wait
for the RSSI_VALID flag?
2) if the radio doesnt transmit for a long time, is the RSSI  continuously
updated every 8 periods of symbol and the RSSI_VALID flag is everytime high
(this question is related to the first one)?
