Yes you can using MQTT

Have a look at my code base and example based on Nordic nRF91x here

Please create a new post, since this is a very old thread. Thank you!

This is a few years old so both the asset_tracker_v2 is probably a bit different now but I was going through the github project and I was wondering if I could take this example with the LED and use it for one of the NMOS transistors on the Thingy91?

Thanks!

The current (v1.8.0) version of the asset_tracker_v2 has no support for dynamically setting the LED color, because it is used to signal the current mode the device operates in.

But you can opt to not use the UI overlay, and have a look at how configuration from the cloud is handled. Introduce a new property the configures the LED color and set the LED color accordingly.

Hi, how to do change the LED or even better toggle an output of the Thingy91 by using the Asset Tracker v2 firmware?

Hi Mahendra,

Sorry for the delay.

Here is an example showing how to change the colors of the RGB LED for Thingy:91.

Entering this line into the terminal box in nRF Cloud should change the color of the LED.

{"appId":"LED","messageType":"CFG_SET","data": {"color":"0xAB120F"}}

Here is where you can find the example and a few other examples.

https://github.com/nRFCloud/application-protocols/blob/v1/messages.md

I believe line 877 in main.c for asset_tracker shows how the RGB is changed after receiving a message from cloud. I am trying to find a similar way to do this for the nRF9160 DK.

Best regards,

Håkon
