ESP http and internet disconnection error behaviour question

[AndrewM]

Hi,

What happens if there is a Wi-Fi disconnection event (eg: Wi-Fi AP kicks device or turns off) in the middle of an HTTP transaction?

Such as this transaction:

Code: Select all

    esp_http_client_config_t ota_check = {
        .url = OTA_CHECK_URL,
        .event_handler = _http_event_handler,
        .cert_pem = (char *)server_cert_pem_start
    };
    esp_http_client_handle_t client = esp_http_client_init(&ota_check);
    
    esp_err_t err = esp_http_client_perform(client);
    if(err == 0) {
        int statuscode = esp_http_client_get_status_code(client);
        int length = esp_http_client_get_content_length(client);
        esp_err_t err2 = esp_http_client_read(client, readbuffer, length);
    }
    esp_http_client_cleanup(client);
