 * @brief Find Me Profile Target.
 *
 * In the Find Me BLE Profile, the device that is in Target role will act as GATT server.
 *
 * The Target will react to alert levels written by the Locator in the Alert Level
 * Characteristic of the Immediate Alert Service(IAS) present in the ATT DB of the device.
 *
 * The interface of this role to the Application is:
 *  - Enable the profile role (from APP)
 *  - Disable the profile role (from APP)
 *  - Indicate that the alert level has been written by the Locator. (to APP)
 *
 * There shall be only one IAS instance on the device. There shall be only one
 * Alert Level Characteristic in the IAS. The characteristic properties shall be
 * Write No Response only.
 *
 *  The enable/disable of the profile and devices disconnection is handled in the application,
 *  depending on its User Input.
