How to work blynk?

-how apps blynk communicate with the server and the server with arduino?
-proktokol what used to communicate it?

The communication is held via TCP (secured via TLS) using custom developed application protocol. Since the server is open source, you can easily find and study details you need.

I’ll provide better docs soon and update this thread as this is popular question.
