New additions to the TagoIO MQTT broker have been released this week. There are new levels of QoS support and message retention options available for the devices that connect using MQTT protocol.
The Quality of Service (QoS) level is an agreement between the sender of a message and the receiver of a message that defines the guarantee of delivery for a specific message.
TagoIO officially supports QoS 0 and 1.
Also, the TagoIO MQTT broker can retain the last message to each topic if the client chooses to do so, and every time any client subscribes to that same topic it will receive the retained message.
