/NimBLE-Arduino/src/nimconfig.h:173:30: error: operator '||' has no left operand

This error occurred when I tried to compile a program that requires NimBLE directly from the esp32 library, but it was not available, so I tried this library, and the error appeared.

/NimBLE-Arduino/src/nimconfig.h:173:30: error: operator '||' has no left operand

I'm using ArduinoDroid, But the same error appears on the Arduino IDE. Is there a way to fix this?.

Not sure how this is happening, what version are you using? There is no || operator on that line in the newer versions.
