    Using DFS channels in Jody-w1

    MiDi_4074381

      Hello,

       

      I am using the Jody-W1 chip. I want to use all available channels in 5Ghz (that are allowed in current country). Unfortunately, the only frequencies I see when setting country to US are:

       

      Frequencies:

                              * 5180 MHz [36] (23.0 dBm)

                              * 5200 MHz [40] (23.0 dBm)

                              * 5220 MHz [44] (23.0 dBm)

                              * 5240 MHz [48] (23.0 dBm)

                              * 5745 MHz [149] (13.0 dBm)

                              * 5765 MHz [153] (13.0 dBm)

                              * 5785 MHz [157] (13.0 dBm)

                              * 5805 MHz [161] (13.0 dBm)

                              * 5825 MHz [165] (13.0 dBm)

       

      Country DE gives me even only:

                              * 5745 MHz [149] (13.0 dBm)

                              * 5765 MHz [153] (13.0 dBm)

                              * 5785 MHz [157] (13.0 dBm)

                              * 5805 MHz [161] (13.0 dBm)

                              * 5825 MHz [165] (13.0 dBm)

       

      These are the channels that do not use DFS or are not restricted to "indoors". I set my regdom in linux (iw reg set US), but that does not allow me to use DFS channels.

       

      I even tried to use the commands in Cypress CLM regulatory manual 4.2.6 DFS (Dynamic Frequency Select ion), but At some commands, errors are returned:

       

      wl down

      wl ap 1

      wl mpc 0

      wl band a

      wl mimo_bw_cap 1

      wl dfs_preism 1

          -> Unsupported

       

      wl spect 1

      wl txchain 3

      wl chanspec 100/20

      -> Bad channel

       

      wl chanspec 100/80

          -> Bad channel

       

      wl up

      wl radar 1

          -> Unsupported

       

      Are there any restrictions in the driver or programmed into the chip?

       

      Best regards,

      Michael
