Managing firmware and software updates on IoT devices remotely is crucial for security and performance. Remote updates allow you to patch vulnerabilities, improve features, and maintain device health without physical access. Use secure OTA (Over-The-Air) update protocols, such as HTTPS and MQTT with encryption, to ensure data integrity. Implement version control and rollback features to avoid bricking devices during updates. Automation tools and platforms like AWS IoT or Azure IoT Hub can streamline the process. Always test updates on a small group of devices before full deployment to minimize risks. What tools do you use? remotely update iot
