my micaz motes are going to arrive during this week. I will try both methods
and I'll let you know. I read on the web that the second one have some
problems, by the way I'll let you know soon (I think the CCA pin is set if
RSSI > CCA_THRESHOLD, whenever RSSI is valid).
Tsung-han, basically I need to detect when the energy is higher than a
certain threshold in order to compute some statistics regarding some
physical properties.
thank you

Ciao Roberto,
I think, both cases are possible and depend on what you are interested to
trace
or do, but I would incline on the second, I mean, to use the chip
infrastructure.
you have a good day.
