For our project, our requirement is that the client (CYW43907 Evaluation Kit) needs to switch the frequency/channel of the wifi radio while being associated/on-the-fly. I have tried using wwd_wifi_set_channel. For example, wwd_wifi_set_channel( WWD_STA_INTERFACE, 9 ), in order to switch the radio for tx/rx the packets using channel 9. However, after switching the channel, when I check the channel using wwd_wifi_get_channel(), it still shows the original channel, which means that the channel was not switched to 9.
use case:
- The client (CYW43907 Evaluation Kit) associates with AP on channel 5.
- Every 5 seconds the client switches the channel from 5 to 9 and back to 5 from 9. Basically, it alternates between channel 5 and 9 every 5 seconds without disassociation and reassociation.
Can someone please explain the basic working of wwd_wifi_set_channel function, or how the channel switch assignment is performed on WICED platforms.

hello:
I think the connection will be disconnected in the switch if the device is forced to switch channel.
Every 5 seconds the client switches the channel from 5 to 9 and back to 5 from 9.

Thank you for your answer.
I understand all the negative outcomes of channel switching.
However, before that, the real issue is that the channel does not actually switch using wwd_wifi_set_channel function. Any insights about that?
Basically, how can I make the CYW43907 Evaluation Kit's radio switch the wifi channel without being disassociated?
-Thanks!

Hello:
I do not think we can support the request without disassociation .
