Tibbo – MQTT Library Demo
Tibbo created two small programs that illustrate how easy it is to write MQTT-enabled apps in Tibbo BASIC or Tibbo C. To illustrate the use of the MQTT library, we have created two simple Tibbo BASIC applications called "mqtt_publisher" and "mqtt_subscriber". In our MQTT demo,...
