Question on OTA callback (ota_cb_func)

Hi,

I'm trying to add callback to the OTA function in the switch example:
Code: [Select all] [Expand/Collapse]
  1.    
  2. /* Enable OTA */
  3.     esp_rmaker_ota_config_t ota_config = {
  4.         .ota_cb = &ota_cb_func,
  5.         .server_cert = ESP_RMAKER_OTA_DEFAULT_SERVER_CERT,
  6.     };

And my callback function:
Code: [Select all] [Expand/Collapse]
  1. esp_err_t ota_cb_func(esp_rmaker_ota_handle_t handle, esp_rmaker_ota_data_t *ota_data)
  2. {
  3.     ota_status_t status = OTA_STATUS_IN_PROGRESS;
  4.     char info[1024]="test";
  5.    
  6.     ESP_LOGW(TAG, "OTA URL: %s\r\n", ota_data->url);
  7.     ESP_LOGW(TAG, "OTA Filesize: %d\r\n", ota_data->filesize);
  8.     ESP_LOGW(TAG, "OTA Status: %d\r\n", status);
  9.  
  10.     esp_err_t err = esp_rmaker_ota_report_status(handle, status, info); // reports to OTA server
  11.  
  12.     return err;
  13. }

Admittedly, there is very little information documented. I'm really just stabbing in the dark.

When I tried to update OTA, clearly it wouldn't work:

Is there an example callback implementation, or some additional documentation? I'd appreciate it if you can point me to the relevant information.

Hello,

As per the documentation of esp_rmaker_ota_config_t, the callback can be left NULL if you want to use the default. The default callback can be found here. If you want to use your own callback, here is simpler example:
Code: [Select all] [Expand/Collapse]
  1. esp_rmaker_ota_cb(esp_rmaker_ota_handle_t ota_handle, esp_rmaker_ota_data_t *ota_data)
  2. {
  3.     esp_rmaker_ota_report_status(ota_handle, OTA_STATUS_IN_PROGRESS, "Starting OTA Upgrade");
  4.     esp_http_client_config_t config = {
  5.         .url = ota_data->url,
  6.         .cert_pem = ota_data->server_cert
  7.         .buffer_size = 1024,
  8.         .buffer_size_tx = 1024
  9.     };
  10.     esp_err_t ret = esp_https_ota(&config);
  11.     if (ret == ESP_OK) {
  12.         esp_rmaker_ota_report_status(ota_handle, OTA_STATUS_SUCCESS, "OTA Upgrade finished successfully");
  13.         esp_rmaker_reboot(10);
  14.         return ESP_OK;
  15.     } else {
  16.         esp_rmaker_ota_report_status(ota_handle, OTA_STATUS_FAILED, "OTA Upgrade failed");
  17.     }
  18.     return ESP_FAIL;
  19. }
