P1 does not wake up after timer elpses or on interrupt

Firmware
1

@mdma, I am using sleep mode on the P1 as below, but the P1 does not wake after 30 seconds or on a falling interrupt. I am hoping that you can help me out? I’m using 0.4.5 firmware.

I tested the same code on a photon and the photon functions as it should. (code is below) I also verified that the interrupt on pin D5 on the P1 is working too.

System.sleep(D5, FALLING, 30)

Thanks,

Can you reduce this to a minimal test case please. Thanks!

@mdma, sure I’ll test the minimal case tonight then get back to you.

@mdma, below is my minimal code. Using this the P1 still does not wake up after 15 seconds.


//#include "application.h"

#define acclInterrupt D5 // Acclemeter interrupt pin -

boolean sleep = false;
unsigned long sleepBeginMillis;

//void wakeUp();
//unsigned char getTilt();
//void sleepNow();

void setup(){
  Serial.begin(9600);
  pinMode(acclInterrupt, INPUT_PULLUP);
  attachInterrupt(acclInterrupt, wakeUp, FALLING);
  sleepBeginMillis = millis();
}


void loop() {
  if(millis() - sleepBeginMillis > 15000){
    sleep = true;
    RGB.control(true);
    sleepBeginMillis = millis();
  }

  if(sleep){
    sleepNow();
  }
}

void wakeUp(){
  Serial.print("Interrupt triggered");
  sleep = false;
  sleepBeginMillis = millis();
}

void sleepNow(){
  Serial.print("Going to sleep");
  System.sleep(acclInterrupt, FALLING, 15);
  sleep = false;
  sleepBeginMillis = millis();
  RGB.control(false);
}

@mdma, do you know if waking the P1 works for you? I am still unable to wake it up.

Thanks,

@mdma, Just wondering if you’ve been able to verify the P1 sleep functions? My P1’s never wake up, I’m using 0.4.6.

7

I guess this is related to this issue

8

I just found this on a todo list from last year - I realize this is an old thread - did you get this resolved?

9

@mdma, for the most part, I think there is another thread related to the spare pins that cant wake up the P1

Thanks for check in!
