  • This class provides a tailored interface to the MQTTClient class, for the purpose of connecting to the IBM Bluemix IoT service. It is imported from the 'bluemix' module. The following is an example usage.
  • client = bluemix.Bluemix(ORG, DEVICE_ID, DEVICE_TYPE, AUTH_TOKEN)
    msg = '{d:{value:"42"}}'
    client.publish('desired/topic/to/use', msg)


  • bluemix.Bluemix(ORG, DEVICE_ID, DEVICE_TYPE, AUTH_TOKEN, ssl=False)
  • This constructor creates the Bluemix object, which inherits the MQTTClient Class. Returns the Bluemix object. Arguments are:

    • DEVICE_ID The unique Bluemix identifier for the board that is connecting.
    • DEVICE_TYPE The Bluemix board type.
