Hello all,

Using SendDataOverMQTT project template, i don't see code relevant to push command to the XDK to turn on/off orange or red light on the XDK?  Is it possible? can you please direct me how to do it?

Hi Nicolas,

To turn on/off leds, we have a template application called LedsAndButtons in workbench. It will suite for your usecase. Please refer it.

Thank You 🙂

Sorry, this is not my question.

I'm using SentDataOverMQTT template application and the sensing data is been displayed on a dashboard in the cloud, is it possible from the dashboard to trigger Led on/off?  how to do that?

Thanks,

Nick

Hi Nicolas,

As discussed in https://community.developer.bosch.com/t5/Technical-Support/SentDataOverMQTT-in-Workbench-3-6-1-how-t..., from dashboard you can publish a led on/off message to XDK device with specific topic.

Once published message is received in XDK device side (by subscribing a same topic), You can implement a logic to ON/OFF Led.

For tracking purpose of message threads, please ''accept as solution'' if you got solution.

Thank You 🙂
