OTA firmware updates working perfectly. No more USB cables for every change! Implemented dual partition scheme for safe updates. Rollback if new firmware fails to boot. Version tracking in MQTT messages. Deployed updates to 15 devices from my couch. This is how IoT should work! #ota #firmware #esp32 #embedded
