ESP32 IDF with Blynk without Arduino

Hardware and Blynk Libraries
2

Blynk is very portable, the same C++ source code can be used.
You’ll have to (mostly):

  • Remove Arduino-related stuff like headers and direct pin operations. Similar to what BLYNK_NO_BUILTIN flag does.
  • Implement the connectivity transport adapter. See example in src/Adapters/BlynkSerial.h
  • Implement main include header, like src/BlynkSimpleStream.h
  • Implement utility/debug functions: src/Blynk/BlynkDebug.h, src/utility/utility.cpp
