Blynk NCP arduino uno + esp01

You should read this…

Any Arduino + ESP8266 (AT firmware) to be deprecated?

This can be done. In theory, it can even be done for UNO, but OTA update for these boards is not on our roadmap. BTW, your https://github.com/jandrassy/ArduinoOTA library is used to provide the default/reference OTA implementation for the Primary MCUs.
