2.2.0-rc.1 sleep not working as expected...

[skywatch]

Hi,

I have a pro mini with 1MHz bootloader (running at 3.3v to test).
I am using the door sensor from the 'build' page, with the addition of a sleep function as it will be battery powered.
Here is the code...

// Enable debug prints to serial monitor
//#define MY_DEBUG 

// Enable and select radio type attached
#define MY_RADIO_NRF24
#define MY_RF24_PA_LEVEL RF24_PA_HIGH   //Options are: RF24_PA_MIN, RF24_PA_LOW, RF24_PA_HIGH or RF24_PA_MAX
//#define MY_RADIO_RFM69
//#define MY_NODE_ID 1
#include <SPI.h>
#include <MySensors.h>
#include <Bounce2.h>
unsigned long SLEEP_TIME = 0; // Sleep time between reports (in milliseconds)
#define CHILD_ID 3
#define BUTTON_PIN  3  // Arduino Digital I/O pin for button/reed switch

Bounce debouncer = Bounce(); 
int oldValue=-1;

// Change to V_LIGHT if you use S_LIGHT in presentation below
MyMessage msg(CHILD_ID,V_TRIPPED);

void setup()  
{  
  // Setup the button
  pinMode(BUTTON_PIN,INPUT);
  // Activate internal pull-up
  digitalWrite(BUTTON_PIN,HIGH);

  // After setting up the button, setup debouncer
  debouncer.attach(BUTTON_PIN);
  debouncer.interval(5);
  Serial.begin(4800);
}

void presentation() {
  sendSketchInfo("Door Sensor", "1.0");
  // Register binary input sensor to gw (they will be created as child devices)
  // You can use S_DOOR, S_MOTION or S_LIGHT here depending on your usage. 
  // If S_LIGHT is used, remember to update variable type you send in. See "msg" above.
  present(CHILD_ID, S_DOOR);  
}


//  Check if digital input has changed and send in new value
void loop() 
{
  debouncer.update();
  // Get the update value
  int value = debouncer.read();

  if (value != oldValue) {
     // Send in the new value
     send(msg.set(value==HIGH ? 1 : 0));
     oldValue = value;
     Serial.print("Value change  ");
     Serial.println(value);
  }
    // Sleep until interrupt comes in on motion sensor. Send update every two minute.
 // sleep(digitalPinToInterrupt(BUTTON_PIN), CHANGE, SLEEP_TIME);
}

With this setup it will only work with sleep commented out (ie no sleep function). As soon as I remove the comment from sleep it fails to send on pin change.

I invite anyone to test this out for themselves and tell me if it works or not for you.

Thanks for any help....

Not sure, but your problem may be related to the use of debounce() and sleep().
As on PINs 2+3 there is already some sort of debouncing from mcu side, you may just use the same code as in the motion sensor example without further debouncing.

@rejoe2

Thanks for the reply.

That is bizzare. I would expect the two sketches to be the same as it is basically the same thing (a button press).

I modified the motion to report as a door, here is the code.

/**

I will try and get more time to test this out again. Maybe tomorrow. I wonder if having the nrf24l01+ irq pin attached to the pro mini has some effect? Again will test out when I can.

I have used that same debouncer library but not in a battery powered node. I'm not sure I fully understand how the debouncer library and the sleep in interrupt mode may play together, but I'd bet the problem is there...

You may want to ask the author on the official questions thread here.

@manutremo

Thanks for the input - I did get further with this, but have different issues now. I will get back if I find a solution. I hope to get time this weekend to have a good look into my code and see what the issue might be. Failing this I will post how far I get and ask for more input from the friendly helpful people on here. :)

@skywatch said in 2.2.0-rc.1 sleep not working as expected...:

The irq@nRF is not used yet within MySensors. Afik this is planned for version 3.0 (don't have any link wrt this at the moment).

@rejoe2

Apparently it is implemented....

[rejoe2]

@skywatch Thx for clarification.
Seems this is a very recent development (I only knew this to be planed for V3, so things are ahead of theit time..). Nevertheless, most users will not yet have activated the MY_RX_MESSAGE_BUFFER_FEATURE.

[Yveaux]

@rejoe2 it is a feature currently mainly useful for gateways. Furthermore, only avr is supported, as far as I know.
It has been in for over a year iirr.
