Node is rebooted by waking up from a sleep

[alexsh1]

Hi all,

I have the following code which constantly reboots my node when Interrupted by PIR.
Any idea why?

//#define MY_DEBUG_VERBOSE_SIGNING
//#define MY_SPLASH_SCREEN_DISABLED

// Enable and select radio type attached
#define MY_RADIO_RFM69
#define MY_RFM69_NEW_DRIVER
#define MY_RFM69_ATC_MODE_DISABLED
#define MY_RFM69_FREQUENCY RFM69_868MHZ
#define MY_PARENT_NODE_IS_STATIC
#define MY_PARENT_NODE_ID 0
#define MY_RFM69_NETWORKID (100)
#define MY_NODE_ID 3

#define INT_PIN 6
#define INT_PINN 7
#define SLEEP_TIME 9000000  // 15 min
uint32_t sleepTime = SLEEP_TIME;
int8_t wakeupReason = 0;

#include <MySensors.h>

void setup() {
  Serial.begin(115200);
  PCMSK2 |= bit(PCINT22);
  PCMSK2 |= bit(PCINT23);
  PCIFR |= bit(PCIF2);  // clear any outstanding interrupts
  PCICR |= bit(PCIE2);  // enable pin change interrupts for D0 to D7
  delay(2000);
  pinMode(INT_PIN, INPUT);
  pinMode(INT_PINN, INPUT);
}


void loop() {
  if (wakeupReason == digitalPinToInterrupt(INT_PIN) || wakeupReason == digitalPinToInterrupt(INT_PINN)) {
    Serial.println("Sleep Interrupted!");
    digitalWrite(9, HIGH);
    delay(20);
    digitalWrite(9, LOW);
    // Report sensor status here
  } else if (wakeupReason == MY_WAKE_UP_BY_TIMER) {
    Serial.println("MY_WAKE_UP_BY_TIMER");
    // Report battery level here
  }
  wakeupReason = sleep(digitalPinToInterrupt(INT_PIN), CHANGE, digitalPinToInterrupt(INT_PINN), CHANGE, sleepTime);
}
