Hi Emily,

Well, I guess the best way is to follow the configurations from the samples in the nCS & Zephyr, and other examples from the DevZone.

Also, it is always good to go and look at Kconfig-Reference. Here is example search as per your requirement:

Best regards,

After adding CONFIG_OPENTHREAD and CONFIG_OPENTHREAD_NORDIC_LIBRARY_MASTER to the proj.conf file it now works.

Just so that I understand it better. Are these two always required to be set if I want to work with OpenThread? (Or at least some form of CONFIG_OPENTHREAD_NORDIC_LIBRARY because there seem to be a few different ones)

Thanks a lot for your help!

Emily

Hello,

Thank you for contacting DevZone at NordicSemi.

I would like to ask:

Which nCS version you are using?
How is your callback?

I think all you need is:

function call with callback parameter
definition of callback
header file(s) inclusion
setting project configurations

I was able to compile the sample (light_switch) with the modification as per your query in the ncs v2.2.0.

These are configurations that I have used in the proj.conf:

CONFIG_OPENTHREAD=y
CONFIG_OPENTHREAD_JAM_DETECTION=y
CONFIG_OPENTHREAD_NORDIC_LIBRARY_MASTER=y

And the header files:

#include <openthread/jam_detection.h>

Hope it helps.

Regards,
Naeem
