With the nextion, I wanted to verify if dual state button press messages were sent continuously? Or are they only sent when the button state changes?
A short test in Nextion Editor debug would have revealed hours ago.
0x65 Nextion Return Data is sent in response to touch sensor when
the corresponding Send Component ID checkbox is checked
This means that without intervention only sent when both conditions apply.
- in Dual-State Touch Press Event the checkbox is checked and
- when the screen region occupied by Dual-State has an actual Press.
