Blynk.Air OTA minimal code

Blynk 2.0

I have solved the error “Firmware type mismatch”, by typing once the Space key in the space at this line of code.

#define BLYNK_FIRMWARE_VERSION      "22.09.11"

error 1
error 11402×1006 56.5 KB

I don’t know the reason for this error, but with such a simple operation, I solved the above error.
