MQTT client for IBM Bluemix

Dependencies:   HTS221 LIS3MDL LPS22HB LSM303AGR LSM6DSL MQTT VL53L0X

Getting started with IBM Bluemix

This is the MQTT Client example for mbed OS. It demonstrates how to connect a device with IBM Bluemix, how to get values from sensors, and how to see them on the IBM quickstart website. If you are unfamiliar with IBM Bluemix, we recommend that you read the introduction starting here.

Demo workflow:

  • Connection to the local network with 6LoWPAN ND connection.
  • Connection to the Quickstart Bluemix.
  • Read data sensors.
  • Sends data sensors to the Quickstart Bluemix

You can compile this project in three ways:

1. Using the Online compiler. Just clicking here:

Information

Learn how to use the Online compiler reading https://docs.mbed.com/docs/mbed-os-handbook/en/latest/dev_tools/online_comp/ page.

2. Using the compiler on your PC:

Information

Learn how to use the mbed-cli reading https://docs.mbed.com/docs/mbed-os-handbook/en/latest/dev_tools/cli/ page.
The name of the machine is SILICA_SENSOR_NODE.

3. Exporting to 3rd party tools (IDE) like eclipse, IAR, uvision 5 and more others

Information

Learn how to use the mbed-cli reading https://docs.mbed.com/docs/mbed-os-handbook/en/latest/dev_tools/third_party/ page.

Warning

This example requires a Border Router board. For more details please read the Border Router paragraph from this page.

+ *  We know it works with mbed Client but if you want to add more
+ *  services/communications to the application yourself - please ensure
+ *  you update this configuration accordingly. The default configuration
+ *  can be found from mbedTLS Github:
