* @addtogroup FINDL Find Me Locator
* @ingroup FIND
* @brief Find Me Profile Locator
*
* The FINDL is responsible for providing Find Me profile Locator functionalities to
* upper layer module or application. The device using this profile takes the role
* of find me locator.
*
* Find Me Locator (LOC): A LOC (e.g. PC, phone, etc)
* is the term used by this profile to describe a device that can set an alarm level value
* in the peer Find Me target Device (TG), causing the TG to start a sound or flashing light
* or other type of signal allowing it to be located.
*
* The interface of this role to the Application is:
* - Enable the profile role (from APP)
* - Disable the profile role (from APP)
* - Discover Immediate Alert Service range(from APP) and Send result (to APP)
* - Discover Alert Level Characteristic in the IAS range(from APP) and Send Result (to APP)
* - Set alert level in Target (from APP)
* - Error indications (to APP)
*
* The application should remember the discovered IAS range and Alert Level Char. handles
* for the next connection to a known peer (that may also advertise it supports Find Me Profile.)
* This allows the setting of the alert level to be faster.
*
* The enable/disable of the profile and devices disconnection is handled in the application,
* depending on its User Input.
