    Unable to set/change Country Region 1FX (CYW43364)

      Hi,

       

      We are unable to change the Wi-Fi available channels that appears in the "iw list". We want to be able to connect to channels 12 and 13. Seems that by default, the module uses the USA regulatory channels.

       

      iw list:
      
                      Frequencies:
                              * 2412 MHz [1] (20.0 dBm)
                              * 2417 MHz [2] (20.0 dBm)
                              * 2422 MHz [3] (20.0 dBm)
                              * 2427 MHz [4] (20.0 dBm)
                              * 2432 MHz [5] (20.0 dBm)
                              * 2437 MHz [6] (20.0 dBm)
                              * 2442 MHz [7] (20.0 dBm)
                              * 2447 MHz [8] (20.0 dBm)
                              * 2452 MHz [9] (20.0 dBm)
                              * 2457 MHz [10] (20.0 dBm)
                              * 2462 MHz [11] (20.0 dBm)
      

       

      We have tried to install crda:

       

      iw reg set JP
      iw reg get
      global
      country JP: DFS-JP
              (2402 - 2482 @ 40), (N/A, 20), (N/A)
              (2474 - 2494 @ 20), (N/A, 20), (N/A), NO-OFDM
              (4910 - 4990 @ 40), (N/A, 23), (N/A)
              (5030 - 5090 @ 40), (N/A, 23), (N/A)
              (5170 - 5250 @ 80), (N/A, 20), (N/A), AUTO-BW
              (5250 - 5330 @ 80), (N/A, 20), (0 ms), DFS, AUTO-BW
              (5490 - 5710 @ 160), (N/A, 23), (0 ms), DFS
      
      
      global
      country JP: DFS-JP
              (2402 - 2482 @ 40), (N/A, 20), (N/A)
              (2474 - 2494 @ 20), (N/A, 20), (N/A), NO-OFDM
              (4910 - 4990 @ 40), (N/A, 23), (N/A)
              (5030 - 5090 @ 40), (N/A, 23), (N/A)
              (5170 - 5250 @ 80), (N/A, 20), (N/A), AUTO-BW
              (5250 - 5330 @ 80), (N/A, 20), (0 ms), DFS, AUTO-BW
              (5490 - 5710 @ 160), (N/A, 23), (0 ms), DFS
      

      The CRDA shows that all is configured to accept the channles 12 and 13, but iw list, is showing the same available channels.

       

      We have tried to use wl command:

      wl -i wlan0 country JP
      wl -i wlan0 channels
      1 2 3 4 5 6 7 8 9 10 11 12 13 14
      

       

      The wl shows that all is configured correctly, but any changes in iw list.

       

      Nothing works.

       

      Our linux only is can see the channels from 1 to 11.

       

      About our linux:

      Linux xxxxxx 4.1.15-2.0.1+gb63f3f5 #3 SMP PREEMPT Wed May 31 21:54:57 CEST 2017 armv7l armv7l armv7l GNU/Linux

       

      Can anyone help us? We are really stuck on this. ( 4 days at lest with no result )

       

      Thank you so much in advance to read this post.
