Gsm sim800l esp32

[pramana_putra]

hi
I am having problems with the GSM SIM800L module, I want to use this GSM SIM800L module as a replacement for WiFi so that the data I send can be input to IFTTT. but the program I created doesn't run and doesn't even appear on the serial monitor. Using a SIM CARD is also appropriate and can still be used, but when using the GSM SIM8000L module it cannot run. what's the solution?

#include <Wire.h>
#include <Adafruit_Sensor.h>
#include <Adafruit_BME280.h>
#include <SoftwareSerial.h>

#define SIM800_TX_PIN 27
#define SIM800_RX_PIN 26

SoftwareSerial SIM800(SIM800_TX_PIN, SIM800_RX_PIN);

#define SEALEVELPRESSURE_HPA (1013.25)

Adafruit_BME280 bme; // I2C

const char* IFTTT_API_KEY = "dUAMY_6tEaE9doYwCO0gl2OVmUL-bu4IjVilYf25L24";

void setup() {
  Serial.begin(9600);
  SIM800.begin(9600);

  if (!bme.begin()) {
    Serial.println("Could not find BME280 sensor, check wiring!");
    while (1);
  }

  delay(5000);

  connectGPRS();
}

void loop() {
  float temperature = bme.readTemperature();
  float humidity = bme.readHumidity();
  float pressure = bme.readPressure() / 100.0F;

  Serial.print("Temperature: ");
  Serial.print(temperature);
  Serial.println(" °C");

  Serial.print("Humidity: ");
  Serial.print(humidity);
  Serial.println(" %");

  Serial.print("Pressure: ");
  Serial.print(pressure);
  Serial.println(" hPa");

  sendToIFTTT(temperature, humidity, pressure);

  delay(60000); // Wait for 1 minute before sending data again
}

void connectGPRS() {
  Serial.println("Connecting to GPRS...");
  SIM800.println("AT+SAPBR=3,1,\"Contype\",\"GPRS\"");
  delay(1000);
  SIM800.println("AT+SAPBR=3,1,\"APN\",\"indosatgprs\"");
  delay(1000);
  SIM800.println("AT+SAPBR=1,1");
  delay(5000); // Wait for GPRS connection
  Serial.println("Connected to GPRS");
}

void sendToIFTTT(float temp, float humidity, float pressure) {
  String url = "https://maker.ifttt.com/trigger/GSM_COBA/with/key/dUAMY_6tEaE9doYwCO0gl2OVmUL-bu4IjVilYf25L24";
  url += IFTTT_API_KEY;
  url += "?value1=";
  url += String(temp);
  url += "&value2=";
  url += String(humidity);
  url += "&value3=";
  url += String(pressure);

  Serial.print("Sending data to IFTTT: ");
  Serial.println(url);

  SIM800.println("AT+HTTPINIT");
  delay(2000);
  SIM800.println("AT+HTTPPARA=\"CID\",1");
  delay(2000);
  SIM800.print("AT+HTTPPARA=\"URL\",\"");
  SIM800.print(url);
  SIM800.println("\"");
  delay(2000);
  SIM800.println("AT+HTTPACTION=0");
  delay(10000); // Delay to ensure request is processed
  SIM800.println("AT+HTTPTERM");
}

The first step towards a solution spells: Schematics.

why are you using softwareserial on an ESP32 which has hardware serial ports?
try this code

// // SIM800L EVB ESP32 test using Serial2 (pins 16 Rx  and 17 Tx)

// connect so
// SIM800 5V to ESP32 5V
// SIM800 GND to ESP32 GND
// SIM800 VDD to ESP32 3.3v
// SIM80 TXD to ESP32 pin 16 Rx
// SIM800 TXD to ESP32 pin 17 tx

// AT+CGMI  returns the manufacturer's name
// AT+CGMM returns the MODEM model number
// AT+CGMR returns details of the software and model revision level
// AT+CGSN returns the MODEM's serial number

#include <Arduino.h>

// ESP32 example using HardwareSerial library to access Serial port 2 (pins 16 and 17)
// from https://programming.vip/docs/esp32-use-of-hardwareserial-library.html

#define SERIAL_BAUD 115200

HardwareSerial serial2(2);//Serial port 2

int distance = 0;

void setup() {
  //Initialize serial port 0
  Serial.begin(SERIAL_BAUD);
  //Initialize serial port 2
  serial2.begin(SERIAL_BAUD, SERIAL_8N1);
  Serial.println("\nSIM800 EVB to ESP32 Serial port 2 test");
}

void loop() {
  while (serial2.available() > 0) {
    uint8_t byteFromSerial = serial2.read();
    Serial.write(byteFromSerial);
  }
  while (Serial.available() > 0) {
    uint8_t byteFromSerial1 = Serial.read();
    serial2.write(byteFromSerial1);
  }
}

serial monitor output in response to AT commands

how to checking connection internet sir?

[horace]

do AT commands work?
e.g. AT+CCID should give the SIM ID number
AT+CSQ gives the signal quality

if AT commands work OK what does the serial monitor display when you run your code?

[pramana_putra]

do AT commands it's work, cause Serial monitor displays the SMS ready and call ready commands (this picture). how about connect to internet, i don't understand this problem

@pramana_putra

how about connect to internet

what do you wish to do? try a web search for a topic, e.g. sim800l http get will give plenty of links

okeyy, i will try it. thankyou sir
