OTA System Events
-----------------
ESP HTTPS OTA has various events for which a handler can be triggered by :doc:`the Event Loop library <../system/esp_event>` when the particular event occurs. The handler has to be registered using :cpp:func:`esp_event_handler_register`. This helps in event handling for ESP HTTPS OTA.
:cpp:enum:`esp_https_ota_event_t` has all the events which can happen when performing OTA upgrade using ESP HTTPS OTA.
Event Handler Example
^^^^^^^^^^^^^^^^^^^^^
.. highlight:: c
::
/* Event handler for catching system events */
static void event_handler(void* arg, esp_event_base_t event_base,
int32_t event_id, void* event_data)
{
if (event_base == ESP_HTTPS_OTA_EVENT) {
switch (event_id) {
case ESP_HTTPS_OTA_START:
ESP_LOGI(TAG, "OTA started");
break;
case ESP_HTTPS_OTA_CONNECTED:
ESP_LOGI(TAG, "Connected to server");
break;
case ESP_HTTPS_OTA_GET_IMG_DESC:
ESP_LOGI(TAG, "Reading Image Description");
break;
case ESP_HTTPS_OTA_VERIFY_CHIP_ID:
ESP_LOGI(TAG, "Verifying chip id of new image: %d", *(esp_chip_id_t *)event_data);
break;
case ESP_HTTPS_OTA_DECRYPT_CB:
ESP_LOGI(TAG, "Callback to decrypt function");
break;
case ESP_HTTPS_OTA_WRITE_FLASH:
ESP_LOGD(TAG, "Writing to flash: %d written", *(int *)event_data);
break;
case ESP_HTTPS_OTA_UPDATE_BOOT_PARTITION:
ESP_LOGI(TAG, "Boot partition updated. Next Partition: %d", *(esp_partition_subtype_t *)event_data);
break;
case ESP_HTTPS_OTA_FINISH:
ESP_LOGI(TAG, "OTA finish");
break;
case ESP_HTTPS_OTA_ABORT:
