Question

Clear message

0

Hello, Guys! How are you? I’m working on an APP that uses MQTT connector, and I want to clear my messages. Do I need to use some Nanoflow to do that? *** Limpar = Clear I tried to put the clear button inside of “Chat, From database”, but the button sets for all the messages that I recive. Best regards, Augusto Santana

You can set qos to Exactly_Once_2, then you get wach message exactly once. If you use At_Least_Once_1 you have to confirm the receipt by sending a PUBACK message (http://docs.oasis-open.org/mqtt/mqtt/v3.1.1/os/mqtt-v3.1.1-os.html#_Toc398718043).
