Untangle the spectrum

Embark on an electrifying journey into the heart of wireless technology with our Spectrum Challenge at DefCamp 2024!

In this real-world adventure, participants tackle hands-on challenges involving BLE, WiFi, and UDP, all powered by the mighty ESP32. No simulations or theory here – you’ll be working with actual hardware and networks.
