Testing Antenna dBm Claims with ESP32 RSSI

Описание: Learn how to test and compare different antennas using two ESP32 boards and RSSI (dBm) measurements! 📡📶
In this video, I’ll show you step-by-step how to build a simple antenna RSSI tester that lets you measure and compare signal strength from different antennas.

We use two ESP32s:
one ESP32 as a transmitter
one ESP32 as a receiver that reads the RSSI value in dBm

This setup makes it easy to see which antenna performs better in real-world conditions.

Here’s what you’ll learn:

✅ What RSSI and dBm actually mean
✅ Why antenna testing is important
✅ ESP32 test setup (transmitter & receiver)
✅ How the ESP32 measures RSSI
✅ Full walkthrough of the ESP32 code
✅ Live RSSI readings in dBm
✅ Comparing different antennas
✅ Tips for getting reliable measurements
✅ Common mistakes when testing antennas

Whether you’re experimenting with ESP32 projects, WiFi communication, or just want to know which antenna works best, this video gives you a practical and easy-to-follow testing method.
