ThingSpeak

MATLAB Code:

clc; clear all close all arduino = serialport("COM4",9600); pause(2) writeline(arduino,'AT+SAPBR=3,1,"Contype","GPRS"'); pause(2) writeline(arduino,'AT+SAPBR=3,1,"APN","mtnirancell"'); pause(2) writeline(arduino,'AT+SAPBR =1,1'); pause(2) writeline(arduino,'AT+CLBS=1,1'); pause(4) for x = 1:8 gpsstring = readline(arduino); end splitgps = strsplit(gpsstring,','); Y_Loc = splitgps(3); X_Loc = splitgps(2); disp("http://maps.google.com/maps?q=" + Y_Loc +","+X_Loc);

Arduino Code :

#include SoftwareSerial.h SoftwareSerial Sim800l(10,11); //10->TX sim800 , 11->RX sim800 void setup() { // put your setup code here, to run once: Serial.begin(9600); Sim800l.begin(9600); }

void loop() {

 while(Sim800l.available()){
  Serial.write(Sim800l.read());
 }

 while(Serial.available()){
  Sim800l.write(Serial.read());
 }
}

// use 4.2v power for sim800l and connect arduino ground and sim800 power to eachother

I'm sorry I cant help very well in Portuguese, but I recommend trying the getting started tutorial. Here is a translated version . There is also an example with AT commands in the ThingSpeak library .
