 Both characteristics contain information about PWM pulse width, however one of them stores this information in the form of servo's tilt angle [degrees] and the other one in pulse duration [microseconds].
 This allows the user to control servo in two ways, either with angle or with PWM pulse duration.

-Write callbacks of each characteristic call angle or pulse duration setter function. Both files ``gatt_svr.c`` and ``main.c`` need the access to this variables and thanks to this solution, the extern keyword wasn't used in the application. In addition, the boundary conditions of the updated value are checked in this functions and in the end, PWM fracture update event is put to the queue. ``was_angle_passed`` variable is used to keep track on which of the variables has been passed and changed.
