Hi Oukheir,

I'm afraid that we don't have a good tutorial for the relay application that you want to achieve except for the documentation of the hrm_relay example.

I would suggest you to get familiar with the central application.

Try the central only application, not the relay. Try to get to know how it works. It should start with scan for a device and then connect to it. After you connect to the device you need to do service discovery to find the service and then enable CCCD to get the notification. It's the basics for any central application.

When you and peripheral and central in one application, it's simply combining the code of the central and peripheral in one place. Make sure you configure the number of central and peripheral in sdk_config.h correctly.

If you have a specific question, please let me know.
