RW612 EAPOL 4-Way Handshake delay

[johnny_h]

Dear community, I’m currently working on the Wi-Fi settings for RW612. I’ve noticed a significant delay in the four-way handshake process. As shown below, RW612 takes approximately 45 milliseconds to send M2 back to the AP. Usually, it should be less than 10 milliseconds. This delay could potentially impact the efficiency of roaming.

What could be the potential causes for this extended response time? Thanks.

I am running the test on SDK 24_12_00 with wifi_wpa_supplicant example.

Hello Johnny,

Please see below. It takes a fraction of a second between the messages. 

Below is an attempt i have just done...

Questions

(1) do you have any sniffer log to show if there was any re-tries?

(2) Did you make any changes to the example? Which AP are you using? How did you set the RW612 as a STA (what is the command line info)

(3) Please look into UM11797 NXP Wi-Fi and Bluetooth Debug Feature Configuration for
RW61x Evaluation Board. p 4. If possible, can you enable some of the debug?

(4) at your earliest convenience, please share with us 

- OTA (over the air) sniffer log

- full terminal log 

Thank you!
