The Characteristic Presentation Format descriptor defines the format of the Characteristic Value.
*When encoding an IPv4 address, the uint32 Format type is used.
*When encoding an IPv6 address, the uint128 Format type is used.
*When encoding a Bluetooth address (BD_ADDR), the uint48 Format type is used.
*For a Characteristic Value of 23 and an Exponent of 2, the actual value is 2300
*For a Characteristi Value of 3892 and an Exponent of -3, the actual value is 3.892
*One or more Characteristic Presentation Format descriptors may be present. If multiple of these descriptors are present, then a Aggregate Formate descriptor is present. This descriptor is read only and does not require authentication or authorization to read. This descriptor is composed of five parts: format, exponent, unit, name space and description. The Format field determines how a single value contained in the Characteristic Value is formatted. The Exponent field is used with interger data types to determine how the Characteristic Value is furhter formatted. The actual value = Characteristic Value * 10^Exponent.
