espnow_deinit example request

[poky]

Hi, I'd like to call the espnow_deinit() to release the resources once I'm done with the protocol Do you have a working example to show how it can be done? If I call it directly, it will panic

assert failed: vQueueDelete queue.c:2140 (pxQueue)

Caused by this line

Thanks for the question, we will try to fix it and tell you when test it ok.

@poky you can try the following espnow_deinit:

esp_err_t espnow_deinit(void)
{
    ESP_ERROR_RETURN(!g_espnow_config, ESP_ERR_ESPNOW_NOT_INIT, "ESPNOW is not initialized");

    /**< De-initialize ESPNOW function */
    ESP_ERROR_CHECK(esp_now_unregister_recv_cb());
    ESP_ERROR_CHECK(esp_now_unregister_send_cb());
    ESP_ERROR_CHECK(esp_now_deinit());

    for (int i = 0; i < ESPNOW_TYPE_MAX; ++i) {
        if (g_espnow_queue[i]) {
            uint8_t *tmp_data = NULL;

            while (xQueueReceive(g_espnow_queue[i], &tmp_data, 0)) {
                ESP_FREE(tmp_data);
            }

            vQueueDelete(g_espnow_queue[i]);
            g_espnow_queue[i] = NULL;
        }
    }

    ESP_ERROR_CHECK(esp_event_handler_unregister(WIFI_EVENT, ESP_EVENT_ANY_ID, wifi_event_handler));

    vSemaphoreDelete(g_send_lock);
    g_send_lock = NULL;

    vEventGroupDelete(g_event_group);
    g_event_group = NULL;

    ESP_FREE(g_espnow_config);
    g_espnow_config = NULL;

    return ESP_OK;
}

Hi, thanks for the reply! I've tried the code, but now it shows the following exception:

assert failed: spinlock_acquire spinlock.h:122 (result == core_id || result == SPINLOCK_FREE)

From this line:

https://github.com/espressif/esp-now/blob/60961c6127b3dae7776b93865e9be6ca2c26121d/components/espnow/src/espnow.c#L626

[LJYSP]

Does it show exception everytime? Can you show the log before exception? After espnow_deinit, the forward task will be deleted.

Hi, I'm using the provisioning example to test the deinit function, set as an initiator, and add a delay for the task to finish then call deinit, here's what the code looks like:

After 30s of the task, it's panic and show following messages:

assert failed: vQueueDelete queue.c:2140 (pxQueue)

Hi, thanks for the reply! I've tried the code, but now it shows the following exception:

For this error, can you show the example code and the log before exception?

Please modify this line as follow and check:

Hi, after change, it still crash with following outputs

Please update ESP-NOW to the latest version and have a try.

[poky]

Hi, have the latest version updated, the deinit works fine for the first time, but when init esp now again, the following messages:
