B4X FEED ESP32 listener

[practicalsoft]

I want to build a listener or service that is always up, to receive simple text query/command from ESP32 board, then, that B4J listener exec this query or command and send a text reply back to ESP32 board. this service is running under windows, both computer and ESP32 are sharing the same wi-fi network.

for example, ESP sends letter 'T' to B4J listener, then B4J replies with current date and time of PC.

Your guide lines are appreciated.
TIA
