Very stupid question, but I can’t find a solution, probably it’s so obvious that no one writes about it,

Serial.println('data: '.CONSTANTA); // Не работает Serial.println('data: '+CONSTANTA); // Похоже вообще сложение байт

    See use strncat () here.

      Not quite clear question. You ask how to connect the two strings, and give an example for outputting the string and the variable. If you need to connect the strings, then read about strcat (), and the output of the string and the variable can be done using printf ().
