This project demonstrates a CoAP client that runs STM32F4-Discovery evaluation board + STM32F4DIS-EXT extension board.

Instructions to run the demo:

- Compile the project and run a debug session
- Connect a terminal (115200 bauds, no parity, no flow control) to UART1/3/4 to output log messages
- Plug Ethernet cable
- The board acquires an IPv4 address (using DHCP)
- The board will automatically connect to a test CoAP server (coap.me)
- Press the Tamper/Key button to send a CoAP request to the server
