Hello, because default Blynk mobile app doesn’t support much customization and support compiling, I’m thinking about creating GUI on my own.
But I don’t know how is the protocol between server and app, and protocol between server and hardware. I found a topic here: Blynk’s communication protocol/method? but it is not clear that “custom tcp/ip protocol” is between which and which, and how is the protocol which on top of web socket.
