Noob problem on debugging transmissions

[A Former User]

Hello,

I'm quite new to MySensor and Arduino/Raspberry world.
I'm struggling since few days to add some sensors on Domoticz by using a NRF24L01+ device (Gateway is direclty connected on Rpi3 using SPI).

Currently, i'm trying to send data with a DHT22:
On the sensor part, the monitor displays the following:

0 MCO:BGN:INIT NODE,CP=RNNNA--,VER=2.1.1
4 TSM:INIT
4 TSF:WUR:MS=0
12 TSM:INIT:TSP OK
14 TSM:INIT:STATID=4
16 TSF:SID:OK,ID=4
18 TSM:FPAR
53 TSF:MSG:SEND,4-4-255-255,s=255,c=3,t=7,pt=0,l=0,sg=0,ft=0,st=OK:
759 TSF:MSG:READ,0-0-4,s=255,c=3,t=8,pt=1,l=1,sg=0:0
765 TSF:MSG:FPAR OK,ID=0,D=1
2062 TSM:FPAR:OK
2062 TSM:ID
2064 TSM:ID:OK
2066 TSM:UPL
2070 TSF:MSG:SEND,4-4-0-0,s=255,c=3,t=24,pt=1,l=1,sg=0,ft=0,st=OK:1
4077 TSM:UPL
4079 TSF:MSG:SEND,4-4-0-0,s=255,c=3,t=24,pt=1,l=1,sg=0,ft=0,st=OK:1
6088 TSM:UPL
6090 TSF:MSG:SEND,4-4-0-0,s=255,c=3,t=24,pt=1,l=1,sg=0,ft=0,st=OK:1
8099 TSM:UPL
8101 TSF:MSG:SEND,4-4-0-0,s=255,c=3,t=24,pt=1,l=1,sg=0,ft=0,st=OK:1

While on the Raspberry side (GW):

4;255;3;0;24;1
4;255;3;0;24;1
4;255;3;0;24;1
4;255;3;0;24;1

What is strange, is that I never see any data from the DHT Sensor.
My code:

#include <SPI.h>
#include <Wire.h>
#include <DHT.h>

#define MY_DEBUG                      // Active le mode debug / Enable debug prints to serial monitor
#define MY_RADIO_NRF24                // Mode Radio / Enable and select radio type attached
#define MY_RF24_PA_LEVEL RF24_PA_LOW
#define MY_NODE_ID 4                  // Noeud de l'objet / Object Node

#define RF_CE    9
#define RF_CSN   10
#define CHILD_ID_HUM 1
#define CHILD_ID_TEMP 2
#define HUMIDITY_SENSOR_DIGITAL_PIN 3
#define DHTTYPE DHT22   // DHT 22  (AM2302), DHT11
#include <MySensors.h>  

unsigned long SLEEP_TIME = 10000;     // Sleep time between reads (in milliseconds)
float lastTemp;
float lastHum;
boolean metric = true; 
MyMessage msgHum(CHILD_ID_HUM, V_HUM);
MyMessage msgTemp(CHILD_ID_TEMP, V_TEMP);
int reportCount = 1;

void setup()  { 
}

void presentation(){
  // Send the sketch version information to the gateway and Controller
  sendSketchInfo("Outdoor temperature + Humidity", "1.0");

  // Register all sensors to gateway (they will be created as child devices)
  present(CHILD_ID_HUM, S_HUM);
  present(CHILD_ID_TEMP, S_TEMP);
}

void loop()      { 
  // Temperature
  
  DHT dht(HUMIDITY_SENSOR_DIGITAL_PIN, DHTTYPE, 3); 
  float temperature = dht.readTemperature();
  if (isnan(temperature)) {
      Serial.println("Failed reading temperature from DHT");
  } 
  else {
    Serial.print("T: ");
    Serial.println(temperature);
    if(lastTemp != temperature || reportCount == 10) { 
      lastTemp = temperature;
      send(msgTemp.set(temperature, 1));    
    }
  }

  // Humidity
  float humidity = dht.readHumidity();
  if (isnan(humidity)) {
      Serial.println("Failed reading humidity from DHT");
  } 
  else {
    Serial.print("H: ");
    Serial.println(humidity);
    if(lastHum != humidity || reportCount == 10) { 
      lastHum = humidity;
      send(msgHum.set(humidity, 1));
    }
  }
  
  if(reportCount == 10) {
    reportCount = 1;
  }
  else {
    reportCount++;
  }
  
  sleep(SLEEP_TIME);
}

Shouldn't I see the measurement values in the monitor (serial.print cmd) ?

Thanks for helping !

Do you know the log parser: https://www.mysensors.org/build/parser?
Seems your node doesn't get registered by your controller. The gateway is in inclusion mode?

If there is no registration, your node will never go into loop() - at least in standard configuration.

Wrt. your code, I would recommend to define all of the variables in the header, not in the loop() and - more important to declare the DHT object in setup().

Kind regards

Thanks for the quick answer and advices. I understand my mistake:
It is not linked to the inclusion, but on the Gateway and Nodes versions: (Gateway was on MySensors 1.4, while Nodes were on MySensors 2).
Reconfiguration of the Gateway gives appropriate results and is immediately included in Domoticz !
