Hi joe_su,

You can just create an App Key from in the last tab and assign it to the node.

That's great. After creating the app key and adding it, I can control the device normally.
So is the cause of this problem due to the nRF Mesh app version?

Hi joe_su,

If that is the only thing that has been changed compared to when you last had the issue, then yes, I think so.

It could be the issue fixed here: https://github.com/NordicSemiconductor/Android-nRF-Mesh-Library/commit/c9376ff59631d5e1e70319abab81721f37332b03.
