Sure, this is running on a M5Paper, though I have had something very similar running on a M5Core, This is the small segment of an app written for long rang tag reading at a workshop to track keys and other equipment. I have kept in the tag reading portion. I hope this helps. Some of it is not needed for the reading, just too lazy to remove from the snippet.
