I need to transfer my ECG data from one esp device to another esp device?

1

i tried creating data buckets to store and tranfer data to my 2nd esp but the bucket is not getting created. I am getting error 400

Code for ESP1:
#include <ThingerESP8266.h>
#include <ESP8266WiFi.h>

#define USERNAME “Tanishq_123456”
#define DEVICE_ID “esp8266”
#define DEVICE_CREDENTIAL “electronic”

ThingerESP8266 thing(USERNAME, DEVICE_ID, DEVICE_CREDENTIAL);

const char* ssid = “JioFiber-4”; //–> Your wifi name or SSID.
const char* password = “Tithi@6884”;

const int ecgPin = A0; // Analog input pin for ECG signal

int ecgValue;

void setup() {
Serial.begin(115200);
pinMode(ecgPin, INPUT);
WiFi.begin(ssid, password);
thing.add_wifi(ssid, password);
thing[“ecg11”] >> (pson& out){
out[“ecgval”] = ecgValue;
};

}

void loop() {
thing.handle();
ecgValue = analogRead(ecgPin);
Serial.println(ecgValue);
delay(1000); // Adjust delay as necessary
}

Code for ESP2:
#include <ThingerESP8266.h>
#include <ESP8266WiFi.h>

#define USERNAME “Tanishq_123456”
#define DEVICE_ID “esp8266_2”
#define DEVICE_CREDENTIAL “electronic”

const int ecgLed1Pin = D1; // Red LED 1
const int ecgLed2Pin = D2; // Red LED 2
const int ecgLed3Pin = D3; // Red LED 3
const int ecgLed4Pin = D4; // Green LED 1
const int ecgLed5Pin = D5; // Green LED 2

ThingerESP8266 thing(USERNAME, DEVICE_ID, DEVICE_CREDENTIAL);

const char* ssid = “JioFiber-4”; //–> Your wifi name or SSID.
const char* password = “Tithi@6884”;

void setup() {
Serial.begin(115200);

pinMode(ecgLed1Pin, OUTPUT);
pinMode(ecgLed2Pin, OUTPUT);
pinMode(ecgLed3Pin, OUTPUT);
pinMode(ecgLed4Pin, OUTPUT);
pinMode(ecgLed5Pin, OUTPUT);

WiFi.begin(ssid, password);  
thing.add_wifi(ssid, password);

// Define resource to receive ECG data
thing["myecg"] >> [](pson& in) {
    int ecgValue = in;
    Serial.println(ecgValue);
    controlLEDs(ecgValue);
};

}

void loop() {
thing.handle(); // Handle Thinger.io communication
delay(100); // Adjust delay as necessary
}

void controlLEDs(int ecgValue) {
// Map ECG data range to LED control
if (ecgValue < 200) {
digitalWrite(ecgLed1Pin, HIGH);
digitalWrite(ecgLed2Pin, LOW);
digitalWrite(ecgLed3Pin, LOW);
digitalWrite(ecgLed4Pin, LOW);
digitalWrite(ecgLed5Pin, LOW);
} else if (ecgValue >= 200 && ecgValue < 400) {
digitalWrite(ecgLed1Pin, LOW);
digitalWrite(ecgLed2Pin, HIGH);
digitalWrite(ecgLed3Pin, LOW);
digitalWrite(ecgLed4Pin, LOW);
digitalWrite(ecgLed5Pin, LOW);
} else if (ecgValue >= 400 && ecgValue < 600) {
digitalWrite(ecgLed1Pin, LOW);
digitalWrite(ecgLed2Pin, LOW);
digitalWrite(ecgLed3Pin, HIGH);
digitalWrite(ecgLed4Pin, LOW);
digitalWrite(ecgLed5Pin, LOW);
} else if (ecgValue >= 600 && ecgValue < 800) {
digitalWrite(ecgLed1Pin, LOW);
digitalWrite(ecgLed2Pin, LOW);
digitalWrite(ecgLed3Pin, LOW);
digitalWrite(ecgLed4Pin, HIGH);
digitalWrite(ecgLed5Pin, LOW);
} else {
digitalWrite(ecgLed1Pin, LOW);
digitalWrite(ecgLed2Pin, LOW);
digitalWrite(ecgLed3Pin, LOW);
digitalWrite(ecgLed4Pin, LOW);
digitalWrite(ecgLed5Pin, HIGH);
}
}

I am new to this IoT platform thing please bare me…

Hi,

I guess what you want to do is to send a value from device A to device B, so I recommend you to check the documentation there is an example about communication between devices.

Hope this helps
