Seeeduino with cayenne

[djouani]

hello guys
i am having a problem with my seeeduino board ,
i am not receiving data to my cayenne dashboard

and am using this code

#include <LoRaWan.h>

#include <DHT.h>

#include <TheThingsNetwork.h>
#include <CayenneLPP.h>
#define DHTPIN A0 // the pin we're connected the temperature and humidity  sensor 
#define DHTTYPE DHT11   // DHT 11 
DHT dht(DHTPIN, DHTTYPE);
#define moisture A2 // the pin we're connected the moisture sensor 
int moistureval;

// Set your AppEUI and AppKey
const char *appEui = "xxxxxxxxxxx";
const char *appKey = "xxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxx";


#define loraSerial SerialUSB
#define debugSerial SerialUSB

// Replace REPLACE_ME with TTN_FP_EU868 or TTN_FP_US915
#define freqPlan TTN_FP_EU868

TheThingsNetwork ttn(loraSerial, debugSerial, freqPlan);
CayenneLPP lpp(51);


//define and int variables

//uint8_t addTemperature(uint8_t channel, float celsius);
//uint8_t addRelativeHumidity(uint8_t channel, float rh);








void setup()
{
  //loraSerial.begin(57600);
  //while(!SerialUSB);
  debugSerial.begin(115200);
  pinMode(moisture,INPUT);
  

  // Wait a maximum of 10s for Serial Monitor
  while (!debugSerial && millis() < 1000)
    ;

  debugSerial.println("-- STATUS");
  ttn.showStatus();

  debugSerial.println("-- JOIN");
  ttn.join(appEui, appKey);
  dht.begin();
}

void loop()
{
  debugSerial.println("-- LOOP");

  //ttn.showStatus();
  debugSerial.println();
  debugSerial.println("sensor information");
  debugSerial.println("----------------------------------");
  debugSerial.println("DATA");
  debugSerial.println();

  





  
   temperature =dht.readTemperature()*100 ;
   humidity =dht.readHumidity()*100;
   moistureval = analogRead(moisture);


  debugSerial.print("Temperature");
  debugSerial.println("Temperature");
  debugSerial.print("Humidity");
  debugSerial.println("Humidity");
  debugSerial.print("moisture");
  debugSerial.println("moisture");

  
//
 float t = temperature;
 float h = humidity;




  
 
  lpp.reset();
  lpp.addTemperature(1, t);
  lpp.addRelativeHumidity(2,h );
//  lpp.addmoisture(3, m);
  
  //lpp.addBarometricPressure(2, 1073.21);
  //lpp.addGPS(3, 52.37365, 4.88650, 2);

debugSerial.println("payload");
    byte payload[4]={0};
    
    payload[0] = highByte(temperature);
    payload[1] = lowByte(temperature);
    payload[2] = highByte(humidity);
    payload[3] = lowByte(humidity);
   // payload[4] = highByte(moistureval);
   // payload[5] = lowByte(moistureval);



   int loop;
   for(loop=0; loop < 4; loop++)
   debugSerial.println(payload[loop]);
   











  

  // Send it off
 // ttn.sendBytes(lpp.getBuffer(), lpp.getSize());
   //  SerialUSB.print("Temperature: "+String (temperature));
   //SerialUSB.print("humidity: "+String (humidity));
   ttn.sendBytes(payload, sizeof(payload));

   debugSerial.println();

  delay(10000);
}

i need help please

[shramik_salgaonkar]

you are manually sending raw data and not in cayenne lPP format.

debugSerial.println("payload");
byte payload[4]={0};

payload[0] = highByte(temperature);
payload[1] = lowByte(temperature);
payload[2] = highByte(humidity);
payload[3] = lowByte(humidity);
   // payload[4] = highByte(moistureval);
   // payload[5] = lowByte(moistureval);
   int loop;
   for(loop=0; loop < 4; loop++)
   debugSerial.println(payload[loop]);
  // Send it off
 // ttn.sendBytes(lpp.getBuffer(), lpp.getSize());
   //  SerialUSB.print("Temperature: "+String (temperature));
   //SerialUSB.print("humidity: "+String (humidity));
   ttn.sendBytes(payload, sizeof(payload)); 

replace the entire main function with:

void loop()
{
  debugSerial.println("-- LOOP");
 float t = temperature;
 float h = humidity;
  lpp.reset();
  lpp.addTemperature(1, t;
  lpp.addRelativeHumidity(2,h );

  // Send it off
  ttn.sendBytes(lpp.getBuffer(), lpp.getSize());

  delay(10000);
}

[shramik_salgaonkar]

how can there be two main loops?

[djouani]

its have to be like this?

[shramik_salgaonkar]

yes, that looks fine.

[djouani]

[djouani]

i am getting this in the serial monitor
but on the cayenne side still nothing

why have you commented this?

@djouani

//loraSerial.begin(57600);

sorry it was a mistake

i did uncomment it but still nothing

can you try this code:

you need to set this to your keys.

[djouani]

hello sir

the AppKey = setkey?

[shramik_salgaonkar]

[djouani]

i did with my own

still the same problem

[djouani]

@shramik_salgaonkar did i well set up the cayenne dashboard?

[shramik_salgaonkar]

if you see the serial monitor output, it clearly states that you are having issue connecting to the network.

[shramik_salgaonkar]

@djouani

lora.setKey(“3FB33E70EECACFB206D4589FFD44980E”, “3FB33E70EECACFB206D4589FFD44980E”, “3FB33E70EECACFB206D4589FFD44980E”);

you have still kept the same.
