This prior discussion is NOT about WiringPi (a C++ style of programming for the RPi… and one I gave up trying to use over a year ago).
I thought you said you were more comfortable with Python? I use Python 2 (IDLE) on the RPi to program Python sketches… But if you do not know how to create, edit and run Python on an RPi then you need to Google for tutorials… that level of instruction is not what this forum is about.
Or you can switch gears altogether and go the WiringPi route. It is similar C++ language but different method of editing and compiling than programming in Arduino IDE for Arduino/ESP… but I can’t help you with it.
PS, I am unsure of the disclamer…
We don’t support BLE of Raspberry Pi 3 (yet)
As I use both Python and NodeJS on a RPi3 with Blynk… seems to work just fine.
