Ever wrestled with an embedded unit that had a mind of its own? That was my reality a few years ago.
This unit, built with Linux, C++, and QT, was designed to be a reliable middleman, handling RF frames from a multitude of endpoints.
But it was a bit of a wildcard - unexplained resets, occasional data loss, and all.
It was supposed to support 7500 endpoints, but once we hit 5000, it started to show signs of strain.

The software was a tough nut to crack - maintaining it was a challenge and it wasn't exactly a developer's favorite.
But here's where the plot thickens: after two years of relentless work, we transformed this underdog into a champion.
The unit now supports 10,000 endpoints, with zero resets or data loss.

Intrigued? Join me as I unravel the journey of this remarkable turnaround.
Let's dive into the world of embedded systems and explore how we turned the tide in our favor.
It's a tale of performance improvements, overcoming challenges, and making the impossible possible.
If you've ever wondered how to boost efficiency in embedded systems, or if you're just a fan of a good tech turnaround story, this talk is for you.
