getting started with ble(from scratch)

[etamar]

Hello every one, i want to make a project including a ble chip, i decided to choose one the nrf51 or nrf52 serie, but i am totally unfamiliar with everything!

i have found the libraries, but it is still not so clear how to learn each chip input and output command available, and how to send them with a development kit. if anyone has some tips and things i need to know i will be happy to read them :)

(I know it is allot to learn and i am ready to fill this big gap(i will do it one way or another :) ))

There is a ton of good information out here on this forum to help you get going. Here is but one example of getting going with a development kit: Getting started

Do a search of the forum with terms like "Getting started" and also explore the blog posts.

Good luck!

is everything written there?(i mean everything needed for making an operationg system(and understing what happend and how to extend it), right now I know nothing)

It's really a place to start. You want to get experience with programming the board, using the non-BLE examples and the BLE examples. All of the BLE standard services are implemented and the source code is provided. They make very good starting point for implementing a custom service as well.

You mention an operating system, but unless you are doing a very complex solution it really isn't necessary. The Nordic Soft Device Stack and it's associated SDK provide a very nice event driven solution that gets you a lot of what an OS does without the overhead of tasks, full blown schedulers etc.

I'll add one other thought: There isn't one document that you can read and understand everything about this system. That's why I pointed you at a getting started link. You are going to have to start simple and learn as you go experimenting and trying things. There will be a lot of AHA! moments, and like I said most of the questions you will want to ask probably have already been answered in this forum, searching this forum will be your friend.
