I'm currently trying to get a better understanding of the BLE protocol and I've some questions regarding the structure of GATT - more specifically with regards to what exactly Attributes, Characteristic and Services. And how these interact and make up a profile.

I have tried to create a visual representation of how I imagine a characteristic is made. enter image description here

Unfortunately, I need some respect before I can post an image in the post :( You need at least 10 reputations to post images.

I hope to get a better clarification of how these things link together to form a full-on service :)
