Hi,

I'm using the 802.11 reference design. I want to kown the default parameters of the warp v3 working just as an AP, because I tried to change the tansmitting frequency of the first channel @2.4G.

So, there are three questions I want to ask.

[1]When a warp v3 woking as an AP, was the default channel is channel 1 @2.4G?

[2]Will the transmitter periodically hop to a new random channel?

[3]Importantly, how to change the working channel and the centerfrequency, i kown "the radio_controller_setCenterFrequency" function, but i dont kown how to modify the code.
If you know, please tell me in detail.

Thanks for your help!

The AP's default channel is set by the WLAN_DEFAULT_BSS_CONFIG_CHANNEL macro in wlan_mac_ap.c. The AP does not change frequencies on its own (you could add this if needed). You can modify the AP's default channel by changing the WLAN_DEFAULT_BSS_CONFIG_CHANNEL macro, or using the wlan_exp Python framework on your PC and calling the node.configure_bss(channel=N) method.
