Hi Fares!
Maybe you could add a little more information to your question? Maybe the part of the code with the function.
Did you make any changes to the ble_nus.c file? I don't have any problems compiling the example.

[james tech]

no i didn't make any change that is why i'm wondering

Maybe you could upload your ble_nus.c file, so I can test here?
