ESP HTTPS OTA
=============
Overview
--------
``esp_https_ota`` provides simplified APIs to perform firmware upgrades over HTTPS.
It's an abstraction layer over existing OTA APIs.
Application Example
-------------------
.. highlight:: c
::
esp_err_t do_firmware_upgrade()
{
esp_http_client_config_t config = {
.url = CONFIG_FIRMWARE_UPGRADE_URL,
.cert_pem = (char *)server_cert_pem_start,
};
esp_err_t ret = esp_https_ota(&config);
if (ret == ESP_OK) {
esp_restart();
} else {
return ESP_FAIL;
}
return ESP_OK;
}
Signature Verification
----------------------
For additional security, signature of OTA firmware images can be verified. For that, refer :ref:`secure-ota-updates`
