I'm currently having issues with the OTA feature on my ESP32 Development Board. Particularly, I'm unable to update firmware remotely, the OTA process is not reliable and the encrypted firmware updates are failing. - **ESP32 Background Information:** I'm using an ESP32 Development board for this project. The application running on this hardware was developed using Arduino. - **Necess...

...conversations. The goal is a lightweight, low-latency server that can authenticate users, deliver messages instantly, store chat history, and scale as the user base grows—all without the overhead of group or public room logic. I’m open to proven stacks such as Node.js with WebSocket/, Go with gRPC, or an equivalent solution that plays nicely with iOS and Android clients. End-to-end encryption, push-notification hooks (FCM / APNs), and a RESTful or GraphQL API for ancillary data are highly desirable. Deliverables • Production-ready server code with clear setup instructions • Secure user authentication and encrypted message transport • Message persistence (MongoDB, PostgreSQL, or similar) with indexing for quick retrieval • Simple admin endpo...

I’m building an ecosystem of ESP32-S3-based modules and I’d like to bring a seasoned embedded developer on board for the long haul.

For the initial milestone you will deliver fully-tested, production-ready firmware that proves this trio works seamlessly on the S3: flawless encrypted LoRa packets, a responsive web panel for configuration/monitoring, and a smooth GUI (LVGL or comparable) sharing the same data layer. I’m working with ESP-IDF, but I’m open to your preferred toolchai...
