ESP32C3 does not store variable value in RTC_DATA_ATTR

[PJ_Glasso]

Hi there,
So I did have it working here, well.

Unable to wake the XIAO ESP32C3 up from deep sleep with a PIR sensor

Hi there, 5ven and welcome, I have this code working with a button on D0, Blinks 10 times , Sleeps and wakes up If you press the button. Here’s the code and the Output and a picture of the hardware setup #define LED 10 // or use LED_BUILTIN for on-board LED #define INTERRUPT_PIN 2 RTC_DATA_ATTR int bootCount = 0; void setup() { Serial.begin(115200); delay(1000); pinMode(LED, OUTPUT); digitalWrite(LED, LOW); ++bootCount; Serial.println("Boot number: " + String(bootCount)); …

Sleeps as long as you don’t wake it , Keeps a good boot count.
HTH
