“Do you know about the WiFi signal strength from an ESP? Have you ever thought about getting an ESP01, which has a small antenna, and put it inside a socket? Will it work? To answer these questions, I performed several tests comparing various types of microcontrollers, including ESP32 with ESP8266. We evaluated the performance of these devices at two distances: 1 and 15 meters, both with a wall in between.
All this was performed just to satisfy my own curiosity. What was the result? This was a highlight for ESP02 and ESP32. I will show you all the details in this video below. Check it out:
In addition to the results when comparing the ESP chips, I will tell you today about how to program different ESP chips as Access Points (each on a different channel), how to check the signal strength of each through an application on the smartphone, and finally, we are going to make a general analysis about the signal strength of the networks found.”
