pattern for even number of HEX digits using Nick Gammon's Regexp library

Projects Programming

I use regex pretty much every day but not the Nick Gammon ported library. I can only suggest a couple of things to help diagnose your problem.

  1. Try first to get a regex that will match just "ATS ULTRALIGHT" and write a test sketch to prove it works.
  2. Then create a test sketch that will match just the hex values.

when both of these work flawlessly then merge the two into a third sketch. If you have problems then publish here the 3 sketches.
