Hi community,

I'm trying to update my ESP32 through OTA by downloading a file from my Google Drive.
When I start the OTA update, the system starts to write in the partition but then it quits.
I'm sharing a link to google drive that works as direct download link (tested).

I use an ESP32-WROOM-32 with 4MB of RAM, 1 factory and 2 OTA partition table. ESP-IDF v4.4.

Here I attach my code:

Code: [Select all] [Expand/Collapse]

static esp_err_t
client_event_handler (esp_http_client_event_t * p_evt)
{
    switch (p_evt->event_id)
    {
        case HTTP_EVENT_ERROR:
            ESP_LOGI(TAG, "HTTP_EVENT_ERROR");
        break;
 
        case HTTP_EVENT_ON_CONNECTED:
            ESP_LOGI(TAG, "HTTP_EVENT_ON_CONNECTED");
        break;
 
        case HTTP_EVENT_HEADERS_SENT:
            ESP_LOGI(TAG, "HTTP_EVENT_HEADERS_SENT");
        break;
 
        case HTTP_EVENT_ON_HEADER:
            ESP_LOGI(TAG, "HTTP_EVENT_ON_HEADER, key=%s, value=%s", p_evt->header_key, p_evt->header_value);
        break;
 
        case HTTP_EVENT_ON_DATA:
            ESP_LOGI(TAG, "HTTP_EVENT_ON_DATA, len=%d", p_evt->data_len);
        break;
 
        case HTTP_EVENT_ON_FINISH:
            ESP_LOGI(TAG, "HTTP_EVENT_ON_FINISH");
        break;
 
        case HTTP_EVENT_DISCONNECTED:
            ESP_LOGI(TAG, "HTTP_EVENT_DISCONNECTED");
        break;
    }
 
    return ESP_OK;
}
 
static void
task_ota (void * p_param)
{
    for (;;)
    {
        xSemaphoreTake(gh_ota_semaphore, portMAX_DELAY);
        ESP_LOGI(TAG, "Invoking OTA");
 
        esp_http_client_config_t client_config = {
            .url = "https://drive.google.com/uc?authuser=0&id=1wnJTjI31OjusFE5X4pqWlO_-GpFpfh3c&export=download",
            .event_handler = client_event_handler,
            .cert_pem = (char *) g_server_cert_pem_start,
        };
 
        esp_err_t ret = esp_https_ota(&client_config);
 
        if (ESP_OK == ret)
        {
            ESP_LOGI(TAG, "OTA flash successful for version %d", g_software_version);
            printf("restarting in 5 seconds\n");
            vTaskDelay(5000 / portTICK_PERIOD_MS);
            esp_restart();
        }
        else
        {
            ESP_LOGE(TAG, "Failed to update the firmare, error %s", esp_err_to_name(ret));
        }
    }
}

The error given by the function esp_https_ota() is ESP_ERR_INVALID_ARG. From the documentation I'm not really sure I understood what is, but looking at the code inside this funcion I discovered that this error is returned by esp_https_ota_finish().

Also, it starts writing to partition, but I don't see any HTTP_EVENT_ON_DATA in my client_event_handler(), so I think there is something strange when I try to receive the data.

For an additional test, I used a certificate bundle instead of a single certificate, but the error persists. Maybe something related to the Google Drive platform?

I switched to OneDrive and here the problem is not present.

Has anyone encountered similar problems with Google Drive?

This could be specific to the download URL embedded in the example, please confirm that URL is direct download link. Please check this issue: https://github.com/espressif/esp-idf/issues/8581

Yep:

Seems Google is redirecting you somewhere else.

They talk about a patch for ESP-IDF v5.0. I think it is a similar problem but as ESP_Sprite stated:

ESP_Sprite wrote: Seems Google is redirecting you somewhere else.

I created a direct link URL. Unfortunately Google Drive (as well as One Drive) doesn't release a direct link URL so I followed the instructions in a website to change it.
The link I provide in client_config directly downloads the file (you can try) but I should analize if Google redirects me before the final download.
On the other hand, I though the (eventual) redirect would not a problem if it is performed automatically by the website.
