Sorry for not beeing clear enough.

Ok so I am changing the value of my variable "Start_Number" on my phone from value 0 to value 10. The phone sends the new value (Start_Number = 10) via BLE to the nRF 52840. The nRF52840 is hooked up to the PC in order to debug and programm. I am detecting that a new event happened with the nRF52840, so it obviously received a message. But I am struggling how to get the Data (10) that the nRF 52840 received, in order to process it.

Not sure what you're asking.

Are you asking about how to do this on the Central end - ie, on a PC or phone or tablet ... ?

Yes thanks I've already seen these tutorial. But I can not find a way to extract the Data without the nRF Connect Desktop App. My Goal is to print the values on to console and store them in some containers for further processing.
