Yes, I've polled at ~100ms intervals at some point. And it looked like I get
most of the time only 0 values (for everything - including noisefloor) from
the firmware when I do this. And the actual values are only send every second
or so (I didn't actual make precise calculations here).
I have now prepared a test patch [1] to get the data every 10 seconds. This
was a compromise between having useful information over time and the
overflowing problem. While it is not the perfect solution (QCA *cough*), it is
at least more bearable for me.
Kind regards,
Sven
