I migrated this example to 15.3.0

Sadly i did not fork the project, so no direct linkage here..

This is very useful. Thanks.
I had tried the original code with SDK 15.3 and found it would not work, so it was a relief to find that someone has fixed it for SDK 15.3

Thanks for this @maidenone! BTW yours has the same small error that the original has with regards to the UUID:

In the text, it says this is the UUID that was used:
f364adc9-b000-4042-ba50-05ca45bf8abc

But all the code and screenshots are written with this UUID (two erroneous byte swaps):
f364adc9-00b0-4240-ba50-05ca45bf8abc

It was very confusing to me, as it was kind of a pain figuring out how the byte-ordering is supposed to work. I made a python3 script for this, if anyone is interested:
