Would this be able to connect to the AWS IoT Device Client

I am curious if this would be able to receive events from the Broker on the AWS IoT services, and what it would take to implement that?
Thank you,

Dear MissionaryGamer

Thanks for your interest in the plugin and for asking - definitely a good question :-)

As far as I have seen, AWS IoT Core supports four protocols: MQTT, MQTT over WSS, HTTPS and LoRaWAN (cp. https://docs.aws.amazon.com/iot/latest/developerguide/what-is-aws-iot.html). The former two are interesting here:

• NNG does also support WSS (WebSocket Secure), but I would have to test whether AWS IoT Core MQTT over WSS also works with it.
• Since November 2021 there is also a NanoMQ sub-module available providing with MQTT v3.1.1 for NNG (cp. https://www.emqx.com/en/blog/nanomq-newsletter-202111). Perhaps its use would be the smarter solution.

In both case, if the connection works and data can be transferred, this still needs to be made accessible from the Blueprint Visual Scripting system.

Kind regards,

@brugr9

PS:

AWS IoT support for MQTT is based on the MQTT v3.1.1 specification, but comes with some differences (see AWS IoT differences from MQTT version 3.1.1 specification). Therefore, in my opinion, it would be wiser to create a separate plugin that provides AWS IoT Core MQTT for UE using the SDK you suggested.

Dear MissionaryGamer,

I have checked with EMQ. According to the manufacturer, one can use MQTT messaging broker @nanomq as a proxy:

• See "NanoMQ nng message proxy", In: https://github.com/emqx/nanomq#quick-start
• For, e.g., a Docker image, visit: https://www.emqx.com/en/try?product=nanomq

Kind Regards,

Dear MissionaryGamer,

As of version 5.1, UE provides with a built-in IOT plugin "MQTT". Note: The plugin is Beta (buggy) and is not yet documented,
cp. brugr9/Heartbeat51#1
