Help needed with BLE server/client program

hi, I have two B-WB1M-WPAN1 cards and I would like to create a program that works as a client server, so one card will act as a server and then other client cards will send messages to it via BLE, I saw the example proposed by the company "BLE_HR_p2p_Sensor" which might look like what I want to do but I haven't quite figured out how it all works.
Where can I find, for example, a complete file with commands useful for BLE transmission?
Then if you have any advice they are welcome, I would also be curious to understand how the connection through the application from the phone to the card works.

No For sure, the first one is for a server and now we will have Client configuration. So, you should make some changes.

PS: this discussion became so long. I think if your original request is answered, you may select the best answer with an "accept as Solution". Then, you can keep creating new threads whenever you find that you need help.

Best Regards.

You've posted this in the MPU section, but the B-WB1M-WPAN1 seems to be targetted at MCUs ?

You're using an STM32 MCU, then?

If so, I could move it...

Hello @snak3in and welcome to the ST Community.

For the Client, server part of the question, you can go to this question. I think the answer should be helpful. 

To understand how the BLE transmission works and how the application operates between board and Smartphones, you can use the AN5289. 

Best Regards.

    ok thanks, let's say that I understood a little more about this whole system by looking at what you sent me.
    I still have several doubts however, first of all I created a "server" program on my B-WB1M-WPAN following one of your tutorials on YouTube but when I start it very often I can't see it from the ST BLE Toolboox app, yesterday I noticed that I could see it when I put only the favorites in the filters, today that I'm trying again I can't even see it this way

    Hello @snak3in 

    For a P2P Server application on the B-WB1M-WPAN, the best way for me is to refer to this working application. It includes a .ioc file that should help you to understand the configurations. Also, you can go to the code and check what you have to add. Also, you can refer to this wiki for better explanation.

    Best Regards.
