A very good introduction to the ble Bluetooth protocol stack [Copy link]

Important things to say in advance:

I would be satisfied if I could understand the data that is ultimately exposed to the air during a Bluetooth transmission, and then parse and understand it.

I searched Baidu and saw this article, which is quite good. Let me share it with you.

A simple introduction to the Bluetooth Low Energy (BLE) protocol stack

Although we have been working on smart wearable products for more than two years, we have actually been modifying requirements and performing transplants on existing projects.

I actually know nothing about Bluetooth.

I'm going to pick it up again recently, and I encountered some crappy routines. I have to go through them step by step, which is really annoying.

In the past, I always hoped that I would not have to pay attention to the specific content of the Bluetooth protocol stack, so I didn’t even have the basic knowledge.

But I have also looked at the contents of the Bluetooth protocol stack.

It's quite complicated. I don't understand anything about GAPP or L2CAP.

I don’t want to understand and keep avoiding it.

Now I understand that, just like a fucking routine, you have to drill into it function by function.

I have avoided this thing for so long, I might as well take a look at it.

Of course I still have self-awareness, I just want to have a general understanding, for me, how should I put it?

I would be satisfied if I could understand the data that is ultimately exposed to the air during a Bluetooth transmission, and then parse and understand it.

For those newbies who want to get involved in Bluetooth, I wonder how they got started in the first place.
