https://devzone.nordicsemi.com/f/nordic-q-a/87341/proper-way-to-change-nus-uuid-in-a-zephyr-project---prj-confIn a previous ticket on another topic this question came up. Given it was a tangent to the original topic of that thread, and I think it would be helpful to others, I decided to open a different ticket to address it.

I&#39;ll make a copy of the nus.h/.c files and start form there. I&#39;m guessing I will also have to remove&nbsp;CONFIG_BT_NUS=y from my prj.conf file as well. I&#39;ll give it a try and see if I run into any problems.&nbsp;</p> <p></p> <p>-Brad</p><div style="clear:both;"></div>https://devzone.nordicsemi.com/thread/365168?ContentTypeID=1Wed, 27 Apr 2022 11:53:07 GMT137ad170-7792-4731-bb38-c0d22fbe4515:5e1997cf-acc2-48be-ab14-fee87bfafbadHung Bui<p>Hi Brad,&nbsp;</p> <p>If you are going to make your own service (including the change of UUID), I would suggest to create your own service source and header file .c and .h and remove any relation to the NUS sample service that we provided.&nbsp;</p> <p>If you have a look at the peripheral_ht example you can find that we use the hts.c and hts.h inside src folder. The files are included in the project by the Cmakelists.txt.&nbsp;</p> <p>You can do the same with your own service .c and service .h files. Then you can remove any NUS related declaration in your project.&nbsp;</p><div style="clear:both;"></div>
