Create my own BLE protocol / standard

Projects General Guidance
1

Hello,

I start using bluetooth on my portenta board, and i am trully amazed by how it's working.

It may be crazy idea but i am thinking about creating my own BLE protocol/ standard. To be clear, my goal is not to fork the Arduino BLE library, the goal is to use only the BLE frequences range and not the BLE protocol/ standard.

I don't have any idea where to start and what is involved.

If my understanding is correct, the BLE chip don't handle the BLE protocol, so i should be able to use standard ship and send what i want and how i want it.

If the chip handle this part i'm screwed. Because I will not be able to create my own.

The goal would be : 2 Arduino speaking together with my standard. It would be phase one. And then, well it's depends.

What do you think ?

Thank you !

Edit why I want to do this : I believe it could be an interesting project. I could learn a lot out of things. And after all, why not ?

You forgot to mention, why you want to do this. If you are a beginner, just forget about it right now.

Sure, so you never answered the implied question, what is your experience? The answer to "why not" could be, because you will never succeed.

Also please don't go back and edit your posts to answer responses. It makes the thread confusing to follow.

You are right. But i'm sorry, i would like to give it a shot. And if i have to fail, i will fail. But i will not consider the time spend useless. And if i need to work 2 years, then so be it.

Okay, begin your research and come back with a report in 2 years.

To answer your questions, i have 4 years of C, 3 years of C++.
I have less than a year in electronics.

That's helpful, but you have dramatically underestimated the scope of the project. I suggest you do some research and you will quickly see what I mean.

It is not possible to help here, posting a wall of textbooks and technical manuals and code you would need, would probably crash this forum software. :slight_smile:

A sane approach to a project like this, would be to first completely understand how the existing protocols and implementations work.

That was where Bluetooth was, about 28 years ago. Then, large teams of people starting working on it, got two completely different and incompatible standards working, and they are still evolving.

Have fun!

I may underestimating the amount of work. It's true.

I'm not asking for code, i juste need a tips, or guidance to get started.

If you have a Book, i will be glade, if you could share it to me.

It's called "the internet". AFAIK all or most of the BT engineering is public domain. Surely you can Google it?
