Configuring Thread on nRF5340 DK to run Single Chip architecture

[Harikesh]

Hi, I'm in the evaluation stages and I'm playing around with the nRF5340 DK. I've gone through all the SDK sample applications for OpenThread, as well as the getting started page. I'm trying to flash a thread application onto the nRF board and have it connected remotely to a network to test communication from further away. Unfortunately, every sample OpenThread application on the latest SDK seems to be running in CoProcessor architecture where a device won't be available on a network unless connected to a host processor. Is there a way I can make it so that after connecting my device to the network, I can have it run on power supply externally and not connected to the host processor?

Hi,

Have a look at our nrf/samples/openthread: https://developer.nordicsemi.com/nRF_Connect_SDK/doc/latest/nrf/samples/thread.html

Hi,

Thank you for the response!

I've looked into these samples, and I've testing them. My question is though, when I flash for example the OpenThread CLI application on the board, it only executes the application when plugged into a host computer. How can I get the sample to execute when connected to an external power supply like a usb power bank?

Wrong

The applications run on the board whenever it is powered.
You only get logs from the computer.

If you want to test this, take 2 DKs, and program them with the Coap Client and Coap Server samples.
Then you can use one DK to control the LEDs on the other DK, while both are plugged into power supplies.
