I have a question regarding to the iw list result here:
What does this "no IR" and "radar detection" mean?
Also I would like to know is there way to check if radar is detected? Can i scan for radar on my own somehow?
* 5700 MHz [140] (10.0 dBm) (no IR, radar detection)
* 5745 MHz [149] (10.0 dBm) (no IR)
That's why I picked that first link : "The NO-IR flag then means you cannot use modes of operation that require you to initiate radiation first".
In other words the device can listen for traffic / connections on that channel and join them if appropriate, but it should not be the first to send traffic (that is "initiate radiation" = IR)
