Mini A6 GSM Development Board With GPRS Quad-Band

This is a Mini A6 GSM Devel­op­ment Board With GPRS Quad-Band SMS Audio Board 5V Replace SIM800L. Mini A6 GSM is a great devel­op­ment board for cel­lu­lar and remote mon­i­tor­ing appli­ca­tions. With it, Any­one can eas­i­ly mon­i­tor and con­trol your home from any­where there is cell phone cov­er­age with your GSM cel­lu­lar account. Insert any GSM SIM card and start access­ing this board remote­ly over the cel­lu­lar net­work.This Mod­ule sup­ports GPRS Data Ser­vices and Data ser­vices with the max­i­mum down­load speed of 85.6 Kbps and Upload Speed of 42.8 Kbps. It is com­fort­able with 2G,3G,4G mobile sim Card and sup­ports GSM07.07,07.05 AT, and Ai Thinker exten­sion com­mands.Features:Sup­ports voice calls.Sup­port news SMS.Sup­port stan­dard gsm07.07,07.05 at and ai exten­sion com­mands.Sup­ports 2 ser­i­al, down­load a ser­i­al inter­face, and at the com­mand.Sup­port dig­i­tal audio and ana­log audio, sup­port hr, fr, efr, amr voice cod­ing 11.support.2g 3g 4g mobile uni­com card.Arduino Code –Sending SMSFor send­ing AT com­mands and com­mu­ni­cat­ing with the A6 mod­ule, we will use the ser­i­al mon­i­tor. The sketch below will enable the Arduino to com­mu­ni­cate with the A6 mod­ule on ser­i­al mon­i­tor. Before we pro­ceed with detailed break­down of code, con­nect your Arduino to PC, com­pile below code and upload it to the Arduino.Once you open a ser­i­al mon­i­tor, make sure that ‘Both NL & CR’ option is select­ed!Arduino // --------------------------------------------------------------------------- // Example by Roboticx.ps for IOT-GA6-B Gprs Gsm Module // --------------------------------------------------------------------------- #include <SoftwareSerial.h> #define GSM_RX 2 // Arduino pin 2 to UTX #define GSM_TX 3 // Arduino pin 3 to URX SoftwareSerial sim(GSM_RX, GSM_TX); // // The GSM String number = "0598509120"; //-> change with your number void setup() { Serial.begin(9600); // GPS on 0,1 pin Serial.println("System Started..."); sim.begin(115200); delay(1000); Serial.println("Communicating GSM/GPS....."); sms(); //send sms call(); //call to us } void loop() { //do your code } //loop //-----------GSM Function --------------------------------------------------------- void sms() { Serial.println ("Sending Message"); sim.println("AT CMGF=1"); //Sets the GSM Module in Text Mode delay(1000); Serial.println ("Set SMS Number"); sim.println("AT CMGS=\"" number "\"\r"); //Mobile phone number to send message delay(1000); String SMS = "Sample SMS is sending....."; //sms content sim.println(SMS); delay(100); sim.println((char)26);// ASCII code of CTRL Z delay(1000); } void call() { sim.print (F("ATD")); sim.print (number); sim.print (F(";\r\n")); }1234567891011121314151617181920212223242526272829303132333435363738394041424344454647484950515253545556575859606162636465// —————————————————————————// Exam­ple by Roboticx.ps for IOT-GA6‑B Gprs Gsm Mod­ule // ————————————————————————— #include <SoftwareSerial.h>  #define GSM_RX  2  // Arduino pin 2 to UTX#define GSM_TX  3  // Arduino pin 3 to URX Soft­ware­Se­r­i­al sim(GSM_RX, GSM_TX);  //// The GSM String num­ber = “0598509120”; //-> change with your num­ber    void set­up() {  Ser­i­al.begin(9600); // GPS on 0,1 pin   Ser­i­al.print­ln(“Sys­tem Start­ed…”);  sim.begin(115200);  delay(1000);   Ser­i­al.print­ln(“Com­mu­ni­cat­ing GSM/GPS.….”); sms();   //send smscall();   //call to us } void loop() { //do your code } //loop //———–GSM Func­tion ——————————————————— void sms(){  Ser­i­al.print­ln (“Send­ing Mes­sage”);  sim.print­ln(“AT CMGF=1”);    //Sets the GSM Mod­ule in Text Mode  delay(1000);  Ser­i­al.print­ln (“Set SMS Num­ber”);  sim.print­ln(“AT CMGS=\”” num­ber “\”\r”); //Mobile phone num­ber to send mes­sage  delay(1000);  String SMS = “Sam­ple SMS is send­ing.….”;   //sms con­tent     sim.print­ln(SMS);      delay(100);  sim.print­ln((char)26);// ASCII code of CTRL Z  delay(1000); } void call() {  sim.print (F(“ATD”));  sim.print (num­ber);  sim.print (F(“;\r\n”));   } Link:Ref­er­ence
