Thank you for direction, actually “git clone” method posted by you there are tons of different tutorials and all of them different with different result, so hard for a noob like me
Eventually I succeeded running server and client, but not succeeded with sketches: GPIO pins did work I could turn LED from it, but couldn’t communicate with virtual pins
When edited file main.cpp and restart client nothing happened like it was ignoring this file, default lines were to show input of virtual pin 1 (V1), but when I changed this to V0 it still showed V1 input in console, did search file system for another main.cpp but was not found, so where it taking sketch from if not main.cpp?
Oh wow… that was a long time ago I totally forgot.
Yes my first foray with the RPi was WiringPi. I gave up on it and now use NodeJS and Python instead. Node JS seems so difficult then, but it is actually fairly easy… and very quick to edit/test sketches. Python is very quick as well… make it easier to learn both new languages through trial & error.
So unfortunately I can’t really assist as I have no idea how to properly get WiringPi to work with Blynk… if memory serves me correctly, mainly due to the same reason you are running into. It seemed so complicated to get a simple sketch edited and tested each time.
