how add watchdog to my sensors?

[Reza]

hi
how add watchdog to my sensors?
for example this code:

// Enable debug prints
// #define MY_DEBUG

// Enable and select radio type attached
#define MY_RADIO_NRF24
//#define MY_RADIO_RFM69

#include <SPI.h>
#include <MySensors.h>

unsigned long SLEEP_TIME = 120000; // Sleep time between reports (in milliseconds)
#define DIGITAL_INPUT_SENSOR 3   // The digital input you attached your motion sensor.  (Only 2 and 3 generates interrupt!)
#define CHILD_ID 1   // Id of the sensor child

// Initialize motion message
MyMessage msg(CHILD_ID, V_TRIPPED);

void setup()  
{  
  pinMode(DIGITAL_INPUT_SENSOR, INPUT);      // sets the motion sensor digital pin as input
}

void presentation()  {
  // Send the sketch version information to the gateway and Controller
  sendSketchInfo("Motion Sensor", "1.0");

  // Register all sensors to gw (they will be created as child devices)
  present(CHILD_ID, S_MOTION);
}

void loop()     
{     
  // Read digital motion value
  boolean tripped = digitalRead(DIGITAL_INPUT_SENSOR) == HIGH; 
        
  Serial.println(tripped);
  send(msg.set(tripped?"1":"0"));  // Send tripped value to gw 

  // Sleep until interrupt comes in on motion sensor. Send update every two minute.
  sleep(digitalPinToInterrupt(DIGITAL_INPUT_SENSOR), CHANGE, SLEEP_TIME);
}

@Reza What would be the purpose of the watchdog? To keep the node alive or to make sure the node can make a connection to the gateway?

(btw Please enclose code in code marks to keep it readable. (I did it for you in your posting above)

@AWI
hi ok thank you.
yes watchdog to keep the node alive and to make sure the node can make a connection to the gateway

if (!isTransportReady())
      wait(MY_RECONNECT);

your node just needs to be awake to reconnect to the gateway.
I've set MY_RECONNECT to 5000 (5sec).
So far this works for my sleeping battery node.

isTransportReady could also be isTransportOK. depends on the version you are using.

hi thank you .
for this sketch , where put your code?

#define MY_DEBUG 
#define MY_RADIO_NRF24
#define MY_REPEATER_FEATURE

#include <SPI.h>
#include <MySensors.h>  

#define CHILD_ID_LIGHT 0
#define LIGHT_SENSOR_ANALOG_PIN 0

unsigned long SLEEP_TIME = 30000; 
MyMessage msg(CHILD_ID_LIGHT, V_LIGHT_LEVEL);
int lastLightLevel;


void presentation()  {
  sendSketchInfo("Light Sensor", "1.0");
  present(CHILD_ID_LIGHT, S_LIGHT_LEVEL);
}

void loop()      
{     
  int lightLevel = (1023-analogRead(LIGHT_SENSOR_ANALOG_PIN))/10.23; 
  Serial.println(lightLevel);
  if (lightLevel != lastLightLevel) {
      send(msg.set(lightLevel));
      lastLightLevel = lightLevel;
  }
  wait(SLEEP_TIME);
}

also this is for radio , but for arduino and sensor , how add watchdog ?

@Hermann-Kaiser said:

isTransportOK

isTransportOK is true , but wait(MY_RECONNECT); have error !

[Reza]

@sundberg84

thank you

[Honk]

@Reza this is a #define MY_RECONNECT 5000
just put a time in ms into the wait function.

[Reza]

@Hermann-Kaiser
ok .this is true .
so where i add this ? after sleep(SLEEP_TIME); ???
also this is for radio ? is this right ? so for sensor and arduino !! there are not any function in mysensors?
