Hi, May we have a little more information about how this is supposed to work? It looks like we're supposed to send the information about the matched radar pattern back to the firmware for confirmation? What's the intended behaviour from the firmware? Will the firmware have a hard-coded set of patterns we have to answer in/by? I ask (like Peter, we work together) because we've had to tweak this behaviour a little to actually pass FCC / ETSI DFS certification. My general concern is that this'll cause a lot of false detects on boards that haven't had things tweaked for the given board. As far as I'm aware the DFS parameters are still hard-coded into the firmware image so if you have to change those you're SOL without the relevant NDAs - this makes running the open source DFS stuff a little tricksy on vendor boards. -adrian
