SDIO & WIFI

[DiEitch]

Hi.
When I turn on WiFi

Code: Untitled.cpp Select all

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: Untitled.cpp Select all

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;

}

sdio hangs after esp_wifi_init()

Please help, what happened?

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.
