Thanks for the response. I had enable logging in the process of troubleshooting the first Quad (post on Apr 9) and it did show the wrong button number being reported. I had not repeated the logging with the new device since it appeared the behaviour was the same.
However, I think the definition of “pushed” and “held” is more on track with what’s happening with this one. I get much better results if I think in terms of
- Push is actually Tap - quickly tap once as if tapping your fingers on a table, or seeing if an iron sole plate is hot
- Held is actually Push - make an intentional push as if ringing a doorbell, but don’t hold it down
I find that if I hold down a button for any longer than after the tactile feedback presents, results are completely random. Anything longer than one second is too much.
While following this pattern is working much, much better, it remains a mystery why the longer “held” was so unreliable, but only on certain buttons.
