TCP proxy over MQTT using a cheap ESP32 microcontroller

Full info and code : https://github.com/hack-tramp/ESP-MQTTunnel/ A working PoC that turns an ESP32 into a hardware proxy that tunnels traffic over MQTT. Because it connects to a MQTT broker, you can bypass firewalls/censorship without open ports/public IP (which would be needed for direct ESP32 - laptop comms). All traffic is relayed raw — no TLS...
