ESP32 ESPAsyncWebServer – Server/Client Communication

Posted by heidi.tech

Hello everyone,
I have created a web server on an ESP32 and successfully established communication with the client (my HTML page on my PC). However, the client’s request is for the status of a device connected to the ESP32. Therefore, the ESP32 needs to query this device and send the status to the client.

My question is: How can I simply transmit information from the server to the client without a prior request? Is it possible without using webSocket?
