Further to our posts on the ESP-01 we now have developed a ESP-01 based star system model where we have a central server and soft access point that generates a WiFi network . We have clients that are also based on other ESP-01 modules that can connect to this network ( as many as needed to a reasonable extent). This system now allows us to build a star system of WiFi modules that can be used to sense/control devices connected to the individual modules. More to follow. Please visit the Signal Processing Group Inc. website for more information about us and other articles of interest.
