Hi, How to know that I lost connection on the UART port? any event/listener to detect if there is no more receiver for the data sent on uart?

THX.

By default, there's no way to know that you've disconnected on UART. Your application would need to implement some sort of ACK system, which is not a core feature of the UART protocol.
