Hi.
When I turn on WiFi

Code: [Select all] [Expand/Collapse]

esp_err_t wifi_setup() {
    esp_err_t ret;
 
    WiFi.mode(WIFI_STA);
    WiFi.disconnect(true);
    WiFi.onEvent(WiFiEvent); //not depend
    delay(100);
    return ESP_OK; 
}

sdio_slave is hangs.

I also try init with low level:

Code: [Select all] [Expand/Collapse]

esp_err_t wifi_setup(void)
{
    //s_wifi_event_group = xEventGroupCreate();
    esp_err_t ret;
    tcpip_adapter_init();
    ret = esp_event_loop_create_default();
    if (ret != ESP_OK) return ret;
    wifi_init_config_t cfg = WIFI_INIT_CONFIG_DEFAULT();
    //cfg.event_handler = NULL;
    ret = esp_wifi_init(&cfg); //OK BUT SDIO HALTED AFTER
    if (wf_debug)
    {
      if (ret==ESP_OK) Serial.println("WiFi= Init OK ");
      else Serial.println("WiFi= Init ERR ");
    }
    if (ret != ESP_OK) return ret;
    ret = esp_event_handler_register(WIFI_EVENT, ESP_EVENT_ANY_ID, &event_handler, NULL);
    if (ret != ESP_OK) return ret;
    ret = esp_event_handler_register(IP_EVENT, IP_EVENT_STA_GOT_IP, &event_handler, NULL);
 
//    wifi_config = {
//        .sta = {
//            .ssid = DEFAULT_SSID,
//            .password = DEFAULT_PWD,
////            scan_method : DEFAULT_SCAN_METHOD,
////            sort_method : DEFAULT_SORT_METHOD,
////            .threshold.rssi = DEFAULT_RSSI,
////            .threshold.authmode = DEFAULT_AUTHMODE,
//        }
//
//    };
    return ret;
}

Try selecting the following option in "make menuconfig"

Component config / LWIP /USE_ONLY_LWIP_SELECT [=y].

Hi felixcollins.
Thank for reply.
I had no find this option in LWIP section.

With the best regards.

I check "Support LWIP socket select() only" because
https://github.com/espressif/esp-idf/bl ... ip/Kconfig.

Hi.
I tried to change, but nothing has changed. Can there be something else?
Also I tried to change directly in sdkconfig.

Who can tell, after changing sdkconfig, I need to do something else if I work in the Arduino IDE?

Sorry, I'm not sure what your problem is. You will need to debug deeper in the code and figure out where it is broken - you will probably need JTAG debugging for this.

I just had a problem similar to your one where httpd failed after mounting a file using fat https://www.esp32.com/viewtopic.php?f=13&t=10733

Hallo.

In any case, thanks for the reply!
I create issue: https://github.com/espressif/arduino-esp32/issues/2860
This problem be in arduino and in eclipse too.

But when I use eps32-at with SDIO mode - all works fine in 1 bit mode.

With the best regards.
