https://devzone.nordicsemi.com/f/nordic-q-a/5055/how-to-create-your-own-ble-serviceI want to graduate from hacking my own data through the heart-rate-service (hrs). None of these seem to fulfill my requirements. Is there a document or template from which I can build my custom service?

Then you would follow the outline of a normal, simple service like the battery service and pipe the incoming events to your service. To be able to send data, you can either have a notifiable characteristic, have the peer enable notifications, and then start sending data - OR - you can have service that allows data to be written to on the peer side and use write requests/commands or long writes to push your data.</p><div style="clear:both;"></div>
