WIFI / WPS esp_wifi_connect() returns error

[hansonite]

In the Wifi / WPS example from esp-idf_v4.4-dev-1254-g639e7ad49 the esp_wifi_connect() function is called in the wifi event handlers WIFI_EVENT_STA_DISCONNECTED event. Please make sure to build this example with the current stable esp-idf version 4.2.1.

The esp_wifi_connect() function call returns the following error:
E (16267) wifi:sta is connecting, return error

If you encapsulate esp_wifi_connect() function with the ESP_ERROR_CHECK ... ESP_ERROR_CHECK(esp_wifi_connect());
the following error and an abort occurs:

E (16267) wifi:sta is connecting, return error

So, is there an bugfix planned from espressif side, to address this issue?

Hi,

Were you able to resolve this issue or find out what causes it?

Thanks!

same problem here on example-like program

Code: Select all

sm BSSid: 00:00:00:00:00:00 scan BSSID f8:8e:85:be:8b:76
ESP32 station wps succeeds in enrollee mode
wifi:sta is connecting, return error

esp_wifi_connect returns ESP_ERR_WIFI_CONN
also idk why but in esp-idf function 'wps_finish' ssid and password does not match my settings, are those somehow generated just for this connection or something is clearly wrong?
