WalkType.
A team-built LoRa communication platform.
A PXL team project linking ESP32 handheld devices with a Raspberry Pi gateway for messaging, GPS positions and device status.
What's it all about?
WalkType is a group project in the Electronics-ICT programme at PXL. Handheld devices communicate over LoRa with a Raspberry Pi base station.
I have focused on gateway software in C++/Qt, a binary communication protocol, device state management, acknowledgements, SQLite storage and a web dashboard for messaging and device monitoring.
The puzzle behind the idea.
Handle delivery, retry behaviour and device tracking over a low-bandwidth LoRa connection with duty-cycle constraints.
How I'm building it.
Our team develops hardware and firmware alongside a modular base-station application, testing communication and user interactions iteratively.
My role
Team project. My primary contributions are gateway software, integration and protocol work; hardware and firmware are shared with teammates.
