  • ReflectionsOS

    Reflections is a hardware and software platform for building entertaining mobile experiences.

    • My project is a wrist watch. It uses an ESP32 to get data using HTTPS calls to an nginx service for SSL protocol support to a node.js based service. It is an open-source project and the repository is at https://github.com/frankcohen/ReflectionsOS.

    Experiments in firmware OTA updates for ESP32 dev boards

    • My preferred way to deliver new features and manage SSL certificates is to keep the certificates in the code and use Over The Air (OTA) protocol to update the firmware. I am looking at Chris Joyce's OTA library. The risk of this approach is the SSL certificate expires before the next OTA update. That would require the user to upload firmware over USB to the watch, or return the watch to me for updating.
