 *
 * The BLP module is the responsible block for implementing the Blood Pressure Profile
 * functionalities in the BLE Host.
 *
 * The Blood Pressure Profile defines the functionality required in a device that allows
 * the user (Collector device) to configure and recover blood pressure measurements from
 * a blood pressure device.
