(SOLVED)ESP-IDF: E (588) wifi:failed to post WiFi event=40 ret=259

Postby CraftyZA » Fri Mar 22, 2024 6:51 pm

I'm trying something new. I want to detect certain management packets, then trigger an alarm when detected.

The error above comes from the libnet80211.a library.
I was hoping to see the source somewhere to find out what event=40 ret=259 could mean.
The highlighted code is the line that breaks.

I've tried running the code on a ESP32S as well as a ESP WROOM 32 (the one that has the UNO layout)

Code: Select all

void app_main(void) {
    printf("Starting packet Detection...\n");

    esp_log_level_set("*", ESP_LOG_VERBOSE);

    // Initialize NVS
    esp_err_t ret = nvs_flash_init();
    if (ret == ESP_ERR_NVS_NO_FREE_PAGES || ret == ESP_ERR_NVS_NEW_VERSION_FOUND) {
        ESP_ERROR_CHECK(nvs_flash_erase());
        ret = nvs_flash_init();
    }
    ESP_ERROR_CHECK(ret);

    // Initialize Wi-Fi
    printf("Wifi Init in progress...\n");
    wifi_init_config_t cfg = WIFI_INIT_CONFIG_DEFAULT();
    ESP_ERROR_CHECK(esp_wifi_init(&cfg));
    ESP_ERROR_CHECK(esp_wifi_set_storage(WIFI_STORAGE_RAM));
    ESP_ERROR_CHECK(esp_wifi_set_mode(WIFI_MODE_NULL)); // Set Wi-Fi mode to NULL
    [b][color=#FF0000]ESP_ERROR_CHECK(esp_wifi_start());[/color][/b] // Start Wi-Fi
    esp_wifi_start();
    // Set Wi-Fi mode to promiscuous
    printf("Setting WIFI to promiscuous mode...\n");
    ESP_ERROR_CHECK(esp_wifi_set_promiscuous(true));
    ESP_ERROR_CHECK(esp_wifi_set_promiscuous_rx_cb(&wifi_sniffer_packet_handler));

    ESP_LOGI(TAG, "Wi-Fi initialized");
    printf("Setup Complete. \n");

    // Example: Setup button GPIO pin and attach interrupt handler to stop the alarm
    gpio_set_direction(STOP_BUTTON_GPIO_PIN, GPIO_MODE_INPUT);
    gpio_set_intr_type(STOP_BUTTON_GPIO_PIN, GPIO_INTR_NEGEDGE);
    gpio_install_isr_service(0);
    gpio_isr_handler_add(STOP_BUTTON_GPIO_PIN, stop_alarm, NULL);

    // Main loop
    while (1) {
        // Just keep swimming, just keep swimming
        vTaskDelay(1000 / portTICK_PERIOD_MS); // Delay for 1 second
    }

    // Deinitialize Wi-Fi before application exits
    // ESP_ERROR_CHECK(esp_wifi_stop()); // Stop Wi-Fi
    // ESP_ERROR_CHECK(esp_wifi_deinit()); // Deinitialize Wi-Fi
    // ESP_LOGI(TAG, "Wi-Fi deinitialized");
}

You can print debug information before and after the Wi-Fi initialization steps. This may let you find out where the problem is occurring.

I've made the code pretty verbose in my last update.
Updated main function:

Code: Select all

void app_main(void) {
    printf("Starting packet Detection...\n");

    esp_log_level_set("*", ESP_LOG_VERBOSE);

    ESP_LOGI(TAG, "Before WiFi Initialization");

    // Initialize NVS
    esp_err_t ret = nvs_flash_init();
    if (ret == ESP_ERR_NVS_NO_FREE_PAGES || ret == ESP_ERR_NVS_NEW_VERSION_FOUND) {
        ESP_ERROR_CHECK(nvs_flash_erase());
        ret = nvs_flash_init();
    }
    ESP_ERROR_CHECK(ret);

    // Debug info after NVS initialization
    ESP_LOGI(TAG, "NVS Initialized");

    // Initialize Wi-Fi
    printf("WiFi Init in progress...\n");
    wifi_init_config_t cfg = WIFI_INIT_CONFIG_DEFAULT();
    esp_err_t wifi_init_result = esp_wifi_init(&cfg);
    if (wifi_init_result != ESP_OK) {
        ESP_LOGE(TAG, "Failed to initialize Wi-Fi: %d", wifi_init_result);
    } else {
        ESP_LOGI(TAG, "Wi-Fi Successfully initialized");
    }
    esp_err_t wifi_storage_result = esp_wifi_set_storage(WIFI_STORAGE_RAM);
    if (wifi_storage_result != ESP_OK) {
        ESP_LOGE(TAG, "Failed to set Wi-Fi storage: %d", wifi_storage_result);
    } else {
        ESP_LOGI(TAG, "Wi-Fi RAM storage set");
    }
    esp_err_t wifi_mode_result = esp_wifi_set_mode(WIFI_MODE_NULL);
    if (wifi_mode_result != ESP_OK) {
        ESP_LOGE(TAG, "Failed to set Wi-Fi mode to NULL: %d", wifi_mode_result);
    } else {
        ESP_LOGI(TAG, "Wi-Fi Mode set to NULL");
    }

    esp_err_t wifi_start_result = esp_wifi_start();
    if (wifi_start_result != ESP_OK) {
        ESP_LOGE(TAG, "Failed to start WiFi: %s", esp_err_to_name(wifi_start_result));
    } else {
        ESP_LOGI(TAG, "Started WiFi!");
    }
    
    ESP_LOGI(TAG, "After WiFi Initialization");

    // Set Wi-Fi mode to promiscuous
    printf("Setting Wi-Fi to promiscuous mode...\n");
    ESP_ERROR_CHECK(esp_wifi_set_promiscuous(true));
    ESP_ERROR_CHECK(esp_wifi_set_promiscuous_rx_cb(&wifi_sniffer_packet_handler));

    ESP_LOGI(TAG, "Wi-Fi initialized");
    printf("Setup Complete. \n");

    // Example: Setup button GPIO pin and attach interrupt handler to stop the alarm
    gpio_set_direction(STOP_BUTTON_GPIO_PIN, GPIO_MODE_INPUT);
    gpio_set_intr_type(STOP_BUTTON_GPIO_PIN, GPIO_INTR_NEGEDGE);
    gpio_install_isr_service(0);
    gpio_isr_handler_add(STOP_BUTTON_GPIO_PIN, stop_alarm, NULL);

    // Main loop
    while (1) {
        // Just keep swimming, just keep swimming
        vTaskDelay(1000 / portTICK_PERIOD_MS); // Delay for 1 second
    }

    // Deinitialize Wi-Fi before application exits
    // ESP_ERROR_CHECK(esp_wifi_stop()); // Stop Wi-Fi
    // ESP_ERROR_CHECK(esp_wifi_deinit()); // Deinitialize Wi-Fi
    // ESP_LOGI(TAG, "Wi-Fi deinitialized");
}

Here is the output.

I've made the code pretty verbose in my last update.
Updated main function:

Code: Select all

void app_main(void) {
    printf("Starting packet Detection...\n");

    esp_log_level_set("*", ESP_LOG_VERBOSE);

    ESP_LOGI(TAG, "Before WiFi Initialization");

    if (ret == ESP_ERR_NVS_NO_FREE_PAGES || ret == ESP_ERR_NVS_NEW_VERSION_FOUND) {
        ESP_ERROR_CHECK(nvs_flash_erase());

Still not 100% sure what the issue was, but refactored to just the basics.
Will add new code bit by bit, and keep testing.

Hi CraftyZA,

Did you find a solution or reason for the error?
I am also facing the same after updating esp-idf to v5.2.1. I never used to have this error.

Thanks,
Seans

I think it may have been the loop.

The code above works. Maybe compare and see what is different in your code?

I can confirm that I added the event loop line above:

Code: Select all

 ESP_ERROR_CHECK(esp_event_loop_create_default());
And also changed

Code: Select all

err = esp_wifi_set_mode(WIFI_MODE_STA);
to

Code: Select all

err = esp_wifi_set_mode(WIFI_MODE_NULL);
Errors have stopped completely.

Thanks CraftyZA
