Hi Minjeong Lee,
I ran some test, I used the JN-AN-1223 Version 1014. SDK JN-SW-4168 Build Number 1620.
I created a Zigbee network, joined 2 sensor devices, both devices are Enroll correctly.


Cloud you let me know how to download JN-SW-4168 SDK Ver.1364?
We currently provide the SDK Version 1620. As you know, we have fixed some issues that we found.
I also download latest SDK Ver.1620 and I checked that JN-AN-1223 Ver.1001 is not compiled with the latest SDK as below.
The JN-AN-1223 is not compatible, you must modify the AN to compile. I suggest downloading the latest version JN-AN-1223 1014.
Please let me know if you have issues updating your application.
Regards,
Mario
