Mbed client for AWS IoT Core


This is an Mbed client for AWS IoT Core, based on implementation contributed by Nantis GmbH (Nantis-GmbH/mbed-aws-client). It depends on coreMQTT, coreJSON and AWS IoT Device Shadow library. It can be used to connect devices running Mbed OS to the Azure IoT Hub service, send and receive MQTT messages and work with the Device Shadow service.

Note: This client is not compatible with the old client prior to 5f422c9. Existing users of the old client can continue to fetch that hash, but we strongly recommend migration to the new client.

To use this library, an Mbed OS application needs to

  • connect to a network interface with Internet access
  • get the singleton instance of the client: AWSClient::getInstance()
  • call init(), connect() with required parameters including cloud credentials, message handler and network interface
  • call processResponses() periodically, e.g. using a thread
  • either: interact with an MQTT topic directly using subscribe(), publish()
  • or: use the Device Shadow API: downloadShadowDocument(), getShadowDesiredValue(), publishShadowReportedValue()

Configurations of this library are listed in mbed_lib.json and can be overriden by an application’s mbed_app.json.

An example demonstrating the use of this library has been provided as part of the official Mbed OS examples here.
