Bluetooth Low Energy (BLE) technology is a low-cost, short-distance, interoperable and robust wireless technology. Work on a license-free 2.4GHz ISM RF band. It has been designed for ultra-low power (ULP) wireless technology from the start.It uses many intelligent means to minimize power consumption.Bluetooth low energy technology is used in variable connection intervals. This interval can be set from a few milliseconds to a few seconds depending on t

Description: The override reserved word indicates that the current function overrides the virtual function of the base class.Objective: 1. In the case of more functions, you can prompt the reader that a function overrides the base class virtual function (which means that the virtual function is inherited from the base class, not the derived class itself); 2. Forces the compiler to check whether a function overrides the base class virtual function, and
