Hello, @hirotakaster
I would just like to ask one question. I managed to make your code work communicating between two ESP32s without using libcoap.
For them to work, isn't libcoap necessary? Can we send the commands without it?
On the left, the server created an IP and is functioning as an AP, receiving GET messages.
On the other, the client is sending a Hello World.
