This repository contains the code for the CaseOnline.Azure.WebJobs.Extensions.Mqtt.net6 NuGet Package.

It has been forked from original, because the original was not updated in two years.

This package enables you to:

  • Trigger an Azure Function based on a MQTT Subscription
  • Publish a message to a MQTT topic as a result of an Azure Function
  • With .net 6 support and Azure Functions v4

Are you curious what MQTT is? Check this page!

How to use

Important note when using MQTT triggers: This extension only works when you use AppService Plan! Do not use this with Consumption plan. If you're only using the output binding, using consumption plan is fine!

Where to get

Install stable releases via Nuget with package - CaseOnline.Azure.WebJobs.Extensions.Mqtt.net6

https://www.nuget.org/packages/CaseOnline.Azure.WebJobs.Extensions.Mqtt.net6/

Examples

This is a simple example, receicing messages for topic my/topic/in and publishing messages on topic testtopic/out.

public static class ExampleFunctions
{
    [FunctionName(nameof(SimpleFunction))]
    public static void SimpleFunction(
        [MqttTrigger("my/topic/in")] IMqttMessage message,
        [Mqtt] out IMqttMessage outMessage,
        ILogger logger)
    {
        var body = message.GetMessage();
        var bodyString = Encoding.UTF8.GetString(body);
        logger.LogInformation($"{DateTime.Now:g} Message for topic {message.Topic}: {bodyString}");
        outMessage = new MqttMessage("testtopic/out", new byte[] { }, MqttQualityOfServiceLevel.AtLeastOnce, true);
    }
}

Please find all working examples in the sample project.
