actually, how is this CSI information different from the spectral scan
feature in the ar92xx chipset??

Hello everyone,
I am also interested in accessing CSI. Please update us as soon as you
got some good news.

Dear Andres,
Adrian preliminary confirmed it is possible to get CSI out of
hardware. He helped me to send an internal request to Atheros to
assist on the issue. We sent the request 30 of March.
I am not clear what to do next and I am waiting directions from
Adrian at the moment.
I think that it might be helpful to send to Atheros another request
from you.
Best regards,
Nikolay Makarov
