I'm new to MySensors and I can't get it work right.
I try to send some information (temperature, humidity) from one node (Arduino Nano) to another (Arduino Uno).
First of all, no data is received by second node, if SerialGateway is on.
But that's only a half of a problem.
Even if I turn SerialGateway node off, data is sent and read between nodes, but I still can't get to call incomingMessageCallback function.
- Node which is supposed to receive data:
#include <MySensor.h>
#include <SPI.h>
#define CAQ 10
#define BARO_CHILD 3
#define TEMP_CHILD 4
#define CHILD_ID_HUM 1
#define CHILD_ID_TEMP 2
#define CHILD_ID_MQ 0
float mq=0, pressure=0, baro_temp=0, hum=0, dht_temp=0;
MySensor gw;
void setup(){
gw.begin(incomingMessage, AUTO, false);
gw.sendSketchInfo("Incoming Message Processor", "1.0");
Serial.begin(115200);
// Serial.println("TempDHT \t Hum \t TempBaro \t Pressure \t AirQ");
}
void loop() {
gw.process();
// Serial.print(dht_temp);
// Serial.print("\t");
// Serial.print(hum);
// Serial.print("\t");
// Serial.print(baro_temp);
// Serial.print("\t");
// Serial.print(pressure);
// Serial.print("\t");
// Serial.println(mq);
}
void incomingMessage(const MyMessage &message){
Serial.println("Incoming Message function called");
if (message.isAck()) {
Serial.println("This is an ack from gateway");
} else {
switch (message.sender){
case CAQ:{
Serial.println("CAQ sender detected");
switch(message.sensor){
case CHILD_ID_MQ:
mq=message.getFloat();
break;
case CHILD_ID_HUM:
hum=message.getFloat();
break;
case CHILD_ID_TEMP:
dht_temp=message.getFloat();
break;
case BARO_CHILD:
pressure=message.getFloat();
break;
case TEMP_CHILD:
baro_temp=message.getFloat();
break;
}
}
}
}
}
- Node, which sends data:
#include <SPI.h>
#include <MySensor.h>
#include <DHT.h>
#define CHILD_ID_HUM 1
#define CHILD_ID_TEMP 2
//Pins
#define HUMIDITY_SENSOR_DIGITAL_PIN 4
//DHT-sensor variables:
float lastTempDHT;
float lastHum;
boolean metric = true;
DHT dht;
//My Sensors objects:
MySensor gw;
MyMessage msgHum(CHILD_ID_HUM, V_HUM);
MyMessage msgTemp(CHILD_ID_TEMP, V_TEMP);
void setup()
{
gw.begin(NULL,10, true,AUTO);
dht.setup(HUMIDITY_SENSOR_DIGITAL_PIN);
// Send the sketch version information to the gateway and Controller
gw.sendSketchInfo("Simple Message Sender", "1.0");
gw.present(CHILD_ID_HUM, S_HUM);
gw.present(CHILD_ID_TEMP, S_TEMP, "Temperure DHT");
metric = gw.getConfig().isMetric;
}
void loop()
{
delay(dht.getMinimumSamplingPeriod());
float temperatureDHT = dht.getTemperature();
if (isnan(temperatureDHT)) {
Serial.println("Failed reading temperature from DHT");
} else if (temperatureDHT != lastTempDHT) {
lastTempDHT = temperatureDHT;
if (!metric) {
temperatureDHT = dht.toFahrenheit(temperatureDHT);
}
gw.send(msgTemp.set(temperatureDHT, 1));
Serial.print("T: ");
Serial.println(temperatureDHT);
}
float humidity = dht.getHumidity();
if (isnan(humidity)) {
Serial.println("Failed reading humidity from DHT");
} else if (humidity != lastHum) {
lastHum = humidity;
gw.send(msgHum.set(humidity, 1));
Serial.print("H: ");
Serial.println(humidity);
}
