Open the C++ example up and the first thing I see:

```cpp std::cout << "Received ReportCoordinateFrameSettings" << std::endl; ```

Generally, I've heard `std::endl` instead of \n has bad performance because it forces the statement to print immediately. And because cout is guaranteed to flush anyways when the program ends, you're adding a delay for no reason.

I wonder if there's something I'm not seeing that led to them adopting this rule. e.g. "abnormal program termination" caused by the weapon blowing itself up circumventing a buffer flush?
