I want to push data to blynk server by using sim900A with arduino uno
This is my code
#define BLYNK_PRINT Serial
#define TINY_GSM_MODEM_SIM900
// Default heartbeat interval for GSM is 60
// If you want override this value, uncomment and set this option:
//#define BLYNK_HEARTBEAT 30
#include <TinyGsmClient.h>
#include <BlynkSimpleSIM800.h>
// You should get Auth Token in the Blynk App.
// Go to the Project Settings (nut icon).
char auth[] = "token";
// Your GPRS credentials
// Leave empty, if missing user or pass
char apn[] = "internet";
char user[] = "true";
char pass[] = "true";
// Hardware Serial on Mega, Leonardo, Micro
//#define SerialAT Serial1
// or Software Serial on Uno, Nano
#include <SoftwareSerial.h>
SoftwareSerial SerialAT(2, 3); // RX, TX
TinyGsm modem(SerialAT);
BlynkTimer timer;
// This function sends Arduino's up time every second to Virtual Pin (5).
// In the app, Widget's reading frequency should be set to PUSH. This means
// that you define how often to send data to Blynk App.
void myTimerEvent()
{
// You can send any value at any time.
// Please don't send more that 10 values per second.
Blynk.virtualWrite(V5, millis() / 1000);
}
void setup()
{
// Debug console
Serial.begin(9600);
delay(10);
// Set GSM module baud rate
SerialAT.begin(115200);
delay(3000);
// Restart takes quite some time
// To skip it, call init() instead of restart()
Serial.println("Initializing modem...");
//modem.restart();
// Unlock your SIM card with a PIN
modem.simUnlock("1234");
Blynk.begin(auth, modem, apn, user, pass);
// Setup a function to be called every second
timer.setInterval(1000L, myTimerEvent);
}
void loop()
{
Blynk.run();
timer.run(); // Initiates BlynkTimer
}
and the result is cannot init
