If you are using esp_https_ota, then you need "https" and a certificate. Or you can comment out the checks and use http.

Problem solved. I used dns_gethostbyname() api in my code and passes "example.com" to it. it returns ip address.

OK, so it appears that you are not using the latest esp_https_ota code in the IDF.

Good morning I would like to know how to turn off the check of servers certifications. I'm using ESP-WROVER-KIT v3 eval board**
I've tryied to NULL .cert_pem value in cfg struct or comment out the .cert_pem line.

Code: Select all

esp_http_client_config_t config = {
        .url = CONFIG_FIRMWARE_UPGRADE_URL,
        //.cert_pem = NULL, //(char *)server_cert_pem_start,
        .event_handler = _http_event_handler,
};

But non of this worked out. I'm getting this error (attached picture).
I believe if I turn off the certification check I will be able to use the esp_https_ota command from an http connection.

The url that I'm trying to connect is: http://www.go-on.gr/scripts/updates/hello-world.bin

If i remember this message means that you have turned off https in menuconfig->ESP http client.

In $IDF_PATH/components/esp_https_ota/src/esp_https_ota.c, function esp_https_ota...

Code: Select all

    if (!config->cert_pem) {
        ESP_LOGE(TAG, "Server certificate not found in esp_http_client config");
        return ESP_FAIL;
    }

and for HTTP instead of HTTPS....

Code: Select all

    if (esp_http_client_get_transport_type(client) != HTTP_TRANSPORT_OVER_SSL) {
        ESP_LOGE(TAG, "Transport is not over HTTPS");
        return ESP_FAIL;
    }

Comment out the "return ESP_FAIL;"

hi,
I am using dns_gethostbyname() api to resolve IP. but it takes too much time to get ip.
what will be the problem.

Hello burkulesomesh43.

I think there is no need to use "dns_gethostbyname() api to resolve IP" . I'm using directly the url of the path and I have success in downloading the OTA just fine. For example .url= "https://example.com/take/ota.bin"
If CA cert pem files and all other stuff are ok, I don't think that you will anticipate any problem.
