Problems of sketch not sending notification about esp8266button

[garthvh]

I plan on pushing some changes pretty soon. I wrote it for a talk I gave on IOT, so it is not really in production anywhere. I have not found a solution to the debounce issue, it only happens with ESP01 chips.

I have some stand alone esp8266 chips now, I will try it using your sketch when I have some time

Hi, thanks for this great project!
I have the same issue - it's sometimes simply not working and I don't know why.
I was digging into this debounce clause

// Debounce Button Presses boolean debounce() { boolean retVal = false; int reading = digitalRead(BUTTON_PIN); if (reading != LAST_BUTTON_STATE) { LAST_DEBOUNCE_TIME = millis(); } if ((millis() - LAST_DEBOUNCE_TIME) > DEBOUNCE_DELAY) { if (reading != BUTTON_STATE) { BUTTON_STATE = reading; if (BUTTON_STATE == HIGH) { retVal = true; } } } LAST_BUTTON_STATE = reading; return retVal; }

but no idea what can be the cause.
I have an ESP8266-01 using GPIO2, no LEDs (removed from the code) and connecting GPIO 2 to VCC through some resistor. Like 2-3 out of 10 times it's not working.

Hi garthvh ,

Have you leave the project? I'm trying to make it works, but I don't know if the present code needs a updating.

Thanks for your answer.

I made it work yesterday. Its a good project, I like it. I will prove the new features when you modify the code. I'm going to be attentive.

Thanks again.

New github actions sketch is using new button debounce code
