We have used a similar design in that we double the functionality of the boot button to be a user button. Now I wonder about the GPIO level readings... I was under the assumption that you need to debounce every button, but the boot button seems to not bounce. Is that a feature of ...

My RC based on the design is 1ms. However, I also tried with 1uF cap (RC tim is 10ms). As well, I know that their is a weak pull-up resistor and by default IO0 is 1 by default, but for troubleshooting purposes I soldered 10kOhm TH resistor from the cap to the boot button. ...
