Devices supported by MQ Telemetry

MQTT clients can run on a range of devices, from sensors and actuators, to hand held devices and vehicle systems.

MQTT clients are small, and run on devices constrained by little memory and low processing power. The MQTT protocol is reliable and has small headers, which suits networks constrained by low bandwidth, high cost, and intermittent availability.

MQ Telemetry communicates with telemetry devices through MQTT client applications. These applications use the following resources, all of which implement the MQTT v3 protocol:

• The following client libraries:
  • The MQTT client for Java™ , which is used for building native applications for (for example) Android, OS X, Linux or Windows devices. Applications that use this client library can run on all variations of Java from the smallest CLDC (Connected Limited Device Configuration)/MIDP (Mobile Information Device Profile) through CDC (Connected Device Configuration)/Foundation, J2SE ( Java Platform, Standard Edition), and J2EE ( Java Platform, Enterprise Edition). IBM® jclRM customized class library is also supported. The Java ME platform is generally used on small devices, such as actuators, sensors, mobile phones, and other embedded devices. The Java SE platform is generally installed on higher end embedded devices, such as desktop computers and servers.
  • The MQTT client for C , which is used for building native applications for (for example) iOS, OS X, Linux or Windows devices. This client library provides a C reference implementation together with prebuilt native client for Windows and Linux systems. The C reference implementation enables MQTT to be ported to a wide range of devices and platforms. Some Windows systems on Intel, including Windows 7, RedHat, Ubuntu, and some Linux systems on ARM platforms such as Eurotech Viper, implement versions of Linux that run the C client, but IBM does not provide service support for the platforms. You must reproduce problems with the client on a supported platform if you intend to call your IBM support centre.
  • The MQTT messaging client for JavaScript , which is used for building browser-based web applications.

The MQTT client libraries are available as part of the IBM Messaging Telemetry Clients SupportPac.
