This is a Zenoh-pico test where my PC and the ESP32S2 waits for each other to publish data and to answer. The ESP32S2 waits for data in `demo/example/topic/0` than receives the values, increment +1, and send it back to the PC via `demo/example/topic/1`. The computer gets the data from `demo/example/topic/1` and publishes it back to `demo/example…
