I suggest to start from HRS service, it is explained better than NUS (as you can see from the tutorial link)

If you are running the example without modifications, there will be something missing out of the code.

Do you programmed the softdevice and the application with the right memory addresses (ROM and RAM)?

Thank you for the link.

Dear morpho,

I developed my custom service month ago, and I followed this tutorial. it it well explained. I suggest to read it and code step by step while reading, it helped me a lot.
