Arduino UNO + DFRobot SIM7000 #error "Please define GSM modem model"

[error_in_code_sim7000]

Hi,

Can someone help me with error:

I am using Arduino UNO R3 and DFRobot SIM7000A. This is the code in Arduino:

#include <Wire.h>

#include <TinyGsmClient.h>

#include <SoftwareSerial.h>

#include <TinyGPS++.h>

#include <TinyGPSPlus.h>

#include <DFRobot_SIM7000.h>

#include <DFRobot_SIM.h>

#include <DFRobot_SIMclient.h>

#include <DFRobot_SIMcore.h>

#include <DFRobot_SIMphonecall.h>

#include <DFRobot_SIMsms.h>

// GPS setup

TinyGPSPlus gps;

SoftwareSerial gpsSerial(8, 7); // RX, TX

#define TINY_GSM_MODEM_SIM7000

// SIM7000 setup

SIM7000 sim7000;

// Firebase configuration

#define FIREBASE_HOST "https://XXXXXXXXXXXXXfirebaseio.com" // Replace with your Firebase project URL

#define FIREBASE_AUTH "XXXXXXXXXXXXXXXXX" // Replace with your Firebase secret

void setup() {

Serial.begin(9600);

gpsSerial.begin(9600);

// Initialize SIM7000

sim7000.begin();

sim7000.connectGPRS("super", "", ""); // Use your network APN

// Initialize Firebase

Firebase.begin(FIREBASE_HOST, FIREBASE_AUTH);

}

void loop() {

while (gpsSerial.available()) {

gps.encode(gpsSerial.read());



if (gps.location.isUpdated()) {

  float latitude = gps.location.lat();

  float longitude = gps.location.lng();

  sendDataToFirebase(latitude, longitude);

  delay(5000); // Send data every 5 seconds

}

}

}

void sendDataToFirebase(float lat, float lng) {

String path = "/gps_data";

String data = "{"latitude": " + String(lat) + ", "longitude": " + String(lng) + "}";

Firebase.setString(path, data);

if (Firebase.failed()) {

Serial.print("Failed to send data: ");

Serial.println(Firebase.error());

} else {

Serial.println("Data sent successfully!");

}

}

Would you post the whole error, and post it inside a <CODE> block by clicking the <CODE> button and pasting the error between the three "tick marks" over the text ```type or paste code here``` Also, put your code inside a <CODE> block. This makes the error and the code easier to read.

I have a SIM7000A EVB and I can't even get it to respond to AT commands. Did you every get this resolved?

I used AI, Cody and Clause. It took me 5 weeks, but finally got there. For your SIM7000 hopefully it will be quicker!
