About

This is a simple project to wakeup PC by using remote USB wakeup designed for ESP32 with WiFi module. The project was build around ESP IDF. It works by starting HTTP server and listening for incoming requests. When a request to the specific URI has been made ESP32 will send remote USB wakeup command to a host to wake it up from suspension/hibernation.
