Hey @rei_vilo,
Wanted to follow up here with you. We just Beta released the Cayenne MQTT API! Do you think you could try to use it to get your LaunchPad CC3200 board connected in Cayenne? You can check out the release info here. I’m also offering a $$ reward for submitting code for getting a board connected to Cayenne, if you’re interested 
Let me know! Excited for you to try it out.
