ESP32 wifi connection failure over WPA3

Postby sahil.esp » Wed Aug 18, 2021 5:16 am

When connecting my ESP32 board to WPA3-only mobile hotspot, I am facing connection failure with following error logs:
I (88610) wifi:new:<11,0>, old:<1,0>, ap:<255,255>, sta:<11,0>, prof:1
I (88610) wifi:state: init -> auth (b0)
E (94820) wpa: wpa3: failed to parse SAE commit in state(2)!
I (94830) wifi:state: auth -> init (600)
I (94830) wifi:new:<11,0>, old:<11,0>, ap:<255,255>, sta:<11,0>, prof:1

Disconnection reason: 202 - auth failure

The following are the specifications of the setup:
  • Board: ESP32
    ESP_IDF: v4.3
  • Hotspot: Samsung S21 Plus
    PMF: enabled
    WPA3: enabled
The config option “Enable WPA3-Personal” is enabled, and following code is used for connecting:

Code: Select all

wifi_config.sta.threshold.authmode = WIFI_AUTH_WPA3_PSK;
wifi_config.sta.pmf_cfg.capable = true;
wifi_config.sta.pmf_cfg.required = true;
Kindly provide details of cause of this error, and guidance to resolving the same.

I have made little progress in terms of connection using WPA3 from my esp32 board. Could i receive some support from the espressif community.

From I have seen, this is only capable on the latest chips as the ESP32-S2:

This is not capable in old ESP32 chips in my opinion or did you make it to work?

That is not true; it only says 'ESP32-S2' there because that is the chip you have selected to view the docs for. For instance, here is the ESP32 equivalent.
