Implementing “Telemetry Transport” in Delphi – Paul Jervois

The MQTT (MQ Telemetry Transport) protocol enables a publish/subscribe messaging model in an extremely lightweight way. It is useful for connections with remote locations where a small code footprint is required and/or network bandwidth is at a premium. For example, it has been used in remote sensors communicating to a broker via satellite link, over occasional dial-up connections with healthcare providers, and in a range of home automation and small sensor device scenarios.
