Hello, guys, how is it going?
Well, i am working on a project where i need to send data to Thing Speak and receive an e-mail and notifiction from Blynk App. But i rechead a certain point that i need to put together two programas on the same sketch, like a frankenstein haha.
So, when i put both together, in the app continuous says that the device is conneted and disconneted.
On the other hand Thing Speak is working just fine.
I’m using a NodeMCU ESP-12E module with Arduino IDE
Blynk App 2.27.0
Observation: when i am using them separately it works like a charm!
#include <ESP8266WiFi.h>
#include <BlynkSimpleEsp8266.h>
#include <SimpleTimer.h>

//int alarmPin = 4;
int led1 = 16;
int led2 = 14;//
String apiWritekey = "BX352PBP7BBBFYG4"; // replace with your THINGSPEAK WRITEAPI key here
char auth[] = "2126779495d94c48b7376ec1b15d38ec";
const char* ssid = "ARRIS"; // your wifi SSID name
const char* password = "biricotico29" ;// wifi pasword
const char* server = "api.thingspeak.com";
SimpleTimer timer;
WiFiClient client;
void sendSensor(){
float t = analogRead(0);
Serial.println(t);
Blynk.virtualWrite(V6, t);
// SETUP the ALARM Trigger and Send EMAIL
// and PUSH Notification
if(t > 500){
Blynk.email("antoniolitz22@gmail.com", "Alerta!", "Paciente com frequência acima do normal");
Blynk.notify("Alerta - Frenquencia Cardiaca acima do normal");
}
}
void setup() {
Serial.begin(115200);
timer.run();
Blynk.begin(auth, ssid, password);
WiFi.disconnect();
delay(10);
WiFi.begin(ssid, password);
Serial.println();
Serial.println();
Serial.print("Connecting to ");
Serial.println(ssid);
WiFi.begin(ssid, password);
while (WiFi.status() != WL_CONNECTED) {

}
Serial.println("");
Serial.print("NodeMcu connected to wifi...");
Serial.println(ssid);
Serial.println();
}
void loop() {
float temp = analogRead(A0);
Blynk.run();
if (client.connect(server,80))
{
String tsData = apiWritekey;
tsData +="&field1=";
tsData += String(temp);
tsData += "\r\n\r\n";

client.print(tsData.length());
client.print("\n\n"); // the 2 carriage returns indicate closing of Header fields & starting of data
client.print(tsData);
Serial.print("Temperature: ");
Serial.print(temp);
Serial.println("uploaded to Thingspeak server....");
}
client.stop();
Serial.println("Waiting to upload next reading...");
Serial.println();
// thingspeak needs minimum 15 sec delay between updates
delay(5000);
