Hi,

I am using the CYW43455 core.

The test router provides both 2Ghz and 5Ghz networks with the same ssid.

The scan returns correctly both networks.

I tryied wl join <ssid> -b <bssid> without success

What is actually the right sequence to select one or the other network then to set up the interface ?

Thanks for the help.

Hi Jean,

Regarding question 2:

In my setup, I have two APs with the same SSID called "Raks99". One is on channel 11, other is on channel 36. They have different BSSID. Both are open networks. I am not using external supplicant. The wl commands will use in-driver supplicant to associate

I was able to run "wl join Raks99 --bssid=<2g AP bssid>" and "wl join Raks99 --bssid=<5g AP bssid>". Attached are logs on the command sequence I used. I did not use external wpa_supplicant. Can you check them to make sure you are also doing this in a similar way?

If you want to use external supplicant , you can use 

"network={
bssid=aa:bb:cc:dd:ee:ff
psk="password"
}"

And then start the supplicant by running "wpa_supplicant  wpa_supplicant.conf"

You should be able to connect to the target bssid by both ways :

1. Starting the supplicant or

2. By using wl commands

Please check my logs and let me know if you do not observe similar behavior in your setup. After running the wl join command please wait around 5-10secs to make sure we disassociate with the current AP and join the new one

Regarding 3: The bad channel return is probably because you are using a different clm blob version. You can list out your channels by running "wl chanspecs". Using wl chanspec 3 is fine.

Thanks
