RTOS/CC3220SF-LAUNCHXL: AWS SDk passing messages to mqtt client task

Part Number: CC3220SF-LAUNCHXL

Tool/software: TI-RTOS

I am trying to set up an app that uses uart1 tx/rx to communicate with another chip and have mqtt keep an open subscribe to a topic and being able to publish to another when needed. I have been looking at the simplelink_cc32xx_sdk_1_40_01_00 example for mqtt client. it is very close to what I would like. Is using a message que to communicate with mqtt client. 

When I use the AWS SDK example for sub/pub it works on just a loop. I am trying to add where I can pass data to the task to be published. I have been trying to mimic the way it was done in the simple link sdk but it seem the aws has made so made of their own libraries it isnt that straight foward. some of the apphandlers are par of the message structs and can not tell how this fits into being able to create the que and interact with task.

So I am trying to just to start get a message que working that can communicate with the AWS SDK example mqtt client task. 

Thanks

    Hi Jonathon,

    Can you give an example of where you're having trouble adding a message queue? In general, you can open your queue at the beginning of your task, and use mq_send in your handlers once it's set up.

    If you would like to look at a basic example containing message queues, this SimpleLink Academy module is a good reference: dev.ti.com/.../

    Best regards,
