Ok thanks a lot 🙂

I will take your tips, try to change my Code and give you a feedback!

There are several things that may go wrong here, have you taken a look at:
https://devzone.nordicsemi.com/nordic/short-range-guides/b/bluetooth-low-energy/posts/ble-characteristics-a-beginners-tutorial

There are also some useful comments below the tutorial that is useful.

Typically it should be straight forward enough, make sure that each time you add a service or characteristic, that you have an overview of the handles, since those is needed once you want to send/receive data. This is described in the linked tutorial:

handle: The SoftDevice needs to know what characteristic value we are working on. In applications with two or more characteristics naturally we will need to reference the handle of the specific characteristic value we want to use. Our example only has one characteristic and we will use the handle stored in p_our_service->char_handles.value_handle.

If you are experiencing an assert, then the the application should typically jump to the fault_handler() and you can read out the file name, line number, and error code that is causing the assert by setting a breakpoint there (remember to also define DEBUG). Once you know that, it may be easier to know exactly which line of code is problematic.
