In this video we show a simple ESP32S3 project which reports the signal strength (RSSI) of your Wi-Fi Network via the RGB LED for simple dead zone checking.
Chapters:
00:00 Introduction
00:34 Setup VS and vMicro
00:47 Open Project Example and Configure
01:47 Code Overview
02:11 Serial Output Review
02:29 @Plot Chart Example
02:41 Moving Away from the PC for LIVE usage
This allows you to use a small portable device to check whether your Wi-Fi network reaches the places you need, whether it be for general Wi-Fi usage, or determining where your next IoT project would work best.
Its simple to setup, and can save a lot of time troubleshooting a complex system with an unreliable connection. As your project may well use an ESP32S3 board it makes it even better for testing your next IoT project as it is the same board and antenna you are using.
This can of course be easily adopted for other boards with a few modifications (e.g. Arduino Nano 33 IoT) to yield the same results.
