How to reset nRF52840-DK once the mesh provisioning is done(zephyr onoff-sample)

[nazeer]

Hi,

I am using nRF52840-DK evaluation for testing a Mesh configuration. I was able to successfully establish a mesh connection with a  onoff-sample from zephyr and was able to

control the led's from meshctl tool.

Could you please let me know how do i leave the mesh network. Because when ever i reset the board or reflash the sample , the node is showing its already provisioned. How can i bring back the board to the initial state.

Below is the log from the board after provisioning.

Hi.

Have you tried erasing the flash before reflashing the example?
Simply reflashing might not delete the provisioning data.

Now i am able to erase the flash, i used nrfjprog --family nRF52 --eraseall .

Thank you.

I'm glad to hear that.

I assume that you were able to erase the provisioning data and "bring back the board to the initial state"?

You could also use the nRF Connect - Programmer app to do a complete erase of your board.

Best regards,
Joakim.

Thanks for that info
