Highlights
- The ESP-IDF offers two methods to perform Over The Air (OTA) upgrades: Using the native APIs provided by the app_update component. Using simplified APIs provided by the esp_https_ota component, which provides functionality to upgrade over HTTPS.
- If you want to rollback to the factory app after the upgrade (or to the first OTA partition in case the factory partition does not exist), run the command idf.py erase_otadata. This restores the ota_data partition to its initial state.
- Make sure to run “idf.py erase-flash” after making changes to the partition table.
