Hi I First tested GSM a6 Module with USB to TTL converter(AT COMMAND TESTER)....its works great...
But when i connected it with arduino ...via software serial but it wont showing GSM MODULE RESPONSE as i am sending AT COMMANDS..other serial print works Normal ....
#include <SoftwareSerial.h>
SoftwareSerial myGsm(10,11);
float temp;
int tempPin = 0;
void setup()
{
myGsm.begin(115200);
Serial.begin(115200);
delay(500);
myGsm.println("AT+CIPSHUT");
delay(1000);
printSerialData();
myGsm.println("AT+CIPMUX=0");
delay(2000);
printSerialData();
myGsm.println("AT+CGATT=1");
delay(1000);
printSerialData();
myGsm.println("AT+CGDCONT=1,\"IP\",\"ISAFE\"");
delay(1000);
printSerialData();
myGsm.println();
myGsm.println("AT+CGACT=1,1");
delay(7000);
printSerialData();
myGsm.println("AT+CIFSR"); //init the HTTP request
delay(2000);
printSerialData();
myGsm.println("AT+CIPSTART=\"TCP\",\"122.169.113.165\",\"1883\"");
delay(5000);
printSerialData();
delay(5000);
myGsm.println("AT+CIPSEND");
delay(2000);
printSerialData();
sendtemp();
delay(3000);
myGsm.println("AT+CIPCLOSE");
printSerialData();
myGsm.println("AT+CIPSHUT");
delay(1000);
printSerialData();
}
void loop()
{
}
void printSerialData()
{
while(myGsm.available()!=0)
Serial.write(myGsm.read());
}
void sendtemp()
{
temp = analogRead(tempPin);
temp = temp * 0.48828125;
Serial.print("TEMPERATURE = ");
Serial.print(temp);
Serial.print("*C");
Serial.println();
delay(5000);
myGsm.println(temp);
delay(3000);
printSerialData();
myGsm.write(0x1A);
delay(3000);
printSerialData();
}
This code only prints "TEMPERATURE =","temp" and "*C"...no response of gsm module ..like "OK"
why is it so?i need it for troubleshooting..
