Project Idea:

Create a compact GPS tracker that sends real-time location data via SMS using the A9G Development Board.

Required Components:

• A9G Development Board (GPRS + GSM + GPS + BDS)
• SIM card with SMS and GPRS capability
• Micro USB cable
• GPS antenna (optional but recommended)
• Arduino IDE installed on your PC

How It Works:

1. Insert the SIM card into the A9G module.
2. Connect the board to your computer using the micro USB cable.
3. Upload the code provided below using Arduino IDE (choose the correct COM port).
4. The board connects to GPS satellites and retrieves location coordinates.
5. It sends the GPS location to your phone via SMS.

Example Arduino Code:

 #include <SoftwareSerial.h>
SoftwareSerial A9G(7, 8); // RX, TX  

void setup() 
{   
Serial.begin(9600);   
A9G.begin(9600);   
delay(1000);    
sendAT("AT");   
sendAT("AT+CMGF=1"); // Set SMS mode to text   
sendAT("AT+CGNSPWR=1"); // Power on GPS   
sendAT("AT+CGNSSEQ="RMC""); // Set GPS output format 
}  
void loop() 
{   
Serial.println("Getting GPS location...");   
A9G.println("AT+CGNSINF");   
delay(2000);    
if (A9G.available()) 
{     
String gpsData = A9G.readString();     
Serial.println(gpsData);          
int latIndex = gpsData.indexOf(",") + 1;     
int lonIndex = gpsData.indexOf(",", latIndex) + 1;      
String location = gpsData.substring(latIndex, lonIndex + 10);     
String smsCmd = "AT+CMGS="+1234567890""; // Replace with your phone number      
sendAT(smsCmd);    
delay(1000);     
A9G.print("GPS Location: ");     
A9G.print(location);     
A9G.write(26); // CTRL+Z to send SMS     
delay(10000);   
} 
}  
void sendAT(String cmd) 
{  
A9G.println(cmd);   
delay(1000);   
while (A9G.available()) 
{     
Serial.println(A9G.readString());   
} 
}
