\n\nThis example still shows the use of the now deprecated Baltimore TLS certificate.\n\nPlease check [this post](https://sandervandevelde.wordpress.com/2023/01/25/does-your-azure-iot-edge-ubuntu-device-survive-the-baltimore-certificate-migration/) regarding the TLS certificate replacement. \n\n## Credits\n\nThis repo is inspired by this [blog post](https://www.petecodes.co.uk/connecting-a-raspberry-pi-pico-w-to-microsoft-azure-iot-hub-using-micropython-and-mqtt/) written by my friend Pete Gallagher @pete_codes.\n\n## Demonstrated logic\n\nThe following logic is demonstrated\n\n- Connecting the device to the MQTT broker as part of the IoT Hub\n- Sending device messages\n- Sending user properties alongside of device messages\n- Receiving Direct Methods as event, and responding to it\n- Receiving cloud messages as event\n- Getting cloud messages on startup, being sent while the device was offline\n- Receiving user properties alongside cloud messages\n- Receiving desired properties as event\n- Reading desired properties at the start of the application\n- Sending Reported properties\n\n## Missing logic\n\nThe following logic is missing:\n\n- Supporting another certificate while the baltimore certificate is deprecated soon\n- Creating the SAS token on the device itself so it can be refresh once the current one expires\n- No error handling\n\n## Links\n\n### Docs\n\nhttps://docs.microsoft.com/en-us/azure/iot-hub/iot-hub-mqtt-support\n\n### Samples\n\nhttps://github.com/Azure-Samples/IoTMQTTSample/tree/master/src\n","project_url":"https://awesome.ecosyste.ms/api/v1/projects/github.com%2Fsandervandevelde%2Fnonsdkazureiotclient","html_url":"https://awesome.ecosyste.ms/projects/github.com%2Fsandervandevelde%2Fnonsdkazureiotclient","lists_url":"https://awesome.ecosyste.ms/api/v1/projects/github.com%2Fsandervandevelde%2Fnonsdkazureiotclient/lists"}
