MQTT stands for Message Queue Telemetry Transport . It is a publish/subscribe, extremely simple and lightweight messaging protocol, designed for constrained devices and low-bandwidth, high-latency or unreliable networks.
2017-06-05 sbron I created an MQTT client library and published it on chiselapp

Is there a way to figure out if a client is currently connected to an mqtt broker?
