have done a lot of research but cannot find proper formating for Regexp mask in order to extract a string from another string. Suppose I have the following string: "The quick brown fox ABC3D97 jumps over the lazy wolf" I need to extract the "ABC3D97" based on the mask: /[A-Z]{3}\d{1}[A-Z]{1}\d{2}/ …

My bad, I forgot that Serial.print cannot print these things. You can either use std::cout as in the first example, or convert them to a C-style string like this: Serial.println(output.str().c_str()); This is unfortunate because it creates a copy of the substring (necessary for null termination).
