ESP32 Mesh Firmware
C++ firmware for ESP32 sensor and camera nodes communicating over a Wirepas mesh with MQTT transport.
The problem
Battery-powered sensor nodes deployed across a site need to report and be controlled remotely, without a Wi-Fi access point in range of every device.
What I built
- Wrote firmware handling MQTT, HTTP, and WebSocket transport on constrained hardware, with remote control of motion and camera sensors.
- Ran the nodes over a Wirepas mesh so devices relay through one another rather than each needing direct infrastructure.
Where it landed
- Fleet remotely controllable and reportable from a single MQTT broker.
