Comment (by scottr):
Hi!
I've been looking through some traces, and it appears that we sometimes
get RSSI's that are below the recorded noise floor - which makes sense, as
the noise level is only updated once per interrupt, rather than once per
descriptor (we process multiple descriptors per interrupt). Given that the
signal level = Noise - RSSI, we get an underflow case when RSSI < Noise.
I'll make a note to add some checks for this and it will go in soon(ish).
Thanks!
