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

If the above set of channels are observed using wl channels or wl chan_info, it basically means that the DFS channels have not been enabled internally in the CLM. That is the reason why you cannot set DFS channels.

Have you reached out to the local u-Blox and Cypress sales teams that enabled you on this automotive module?

Hello GauravS_31,

yes I reached the sales team. That was the solution.

Thank you
