Hi everyone,

how can I configure RSDB on CYW 54591 module, connected via pcie on a custom board based on x86 architecture?

On this board I installed a Linux OS, and the support for the chip is good. WiFi works well, both on 2.4GHz and 5GHz, but our customer asked us to separate the two band: he wants 2.4GHz band on main antenna, and 5GHz on aux antenna.

I relly cant find the command to set this configuration, not in wl tool, neither in ifconfig or iw.

 

Regards

Giuseppe

Thank you for the quick answer, but how it is possible to create wlan0 and wlan1 ?

As far as I known the Linux driver for brcmfmac create a single wlan interface per device.

Did I miss some option in my configuration? Or do I need to patch brcmfmac driver for cyg54591 (we already applied the driver patch from Cypress support page).

Regards

Giuseppe

You can consider creating two interfaces wlan0 and wlan1 for main antenna and auxiliary antenna respectively. And you can set the band as shown below:

wl -i wlan0 band b
wl -i wlan1 band a

The wlan0 interface is created after FMAC driver bring up and you can verify using iwconfig. Which configuration(AP/STA/P2P) is being used for the 2.4G antenna and 5G antenna? If it is STA(2.4G)+AP(5G), you can create wlan1 interface for AP, using the iw command shown below:

iw dev wlan0 interface add wlan1 type __ap

Again, you can verify using iwconfig command
