 Let's put this into practice. We will send a UDP message from an nRF54LM20 DK through a HomePod Border Router to Nordic Semiconductor's public echo server found at `udp-echo.nordicsemi.academy:2444`, and receive the response.
 
 The nRF54LM20[^nrf54lm20] is a good fit for Matter. It has an ARM Cortex-M33
