    Why need 2 types of services ?


      In datasheet of BLE I read that exist 2 types of services:


      Service type
       Primary – Represents the primary functionality of the device.
       Secondary – Represents an additional functionality of the device.


      What exactly it mean ? Why need Secondary type ? Why not to use only Primary ?
