* 4) Power on the UNO R3 board and shield, you should see the PWR led is normally on.
* 5) Long press the To Start button, if STA light is on and NET light flashes, release the button.
* 6) Wait for 1-2 minutes, it will call the number set well. After the phone is connected, you can speak through the headphone.

keyestudio Sim800c Shield


Introduction

This is a GPRS/GSM expansion board for Arduino.
The shield supports the frequency of EGSM 900MHz /DCS 1800MHz and GSM850 MHz /PCS 1900MHz, integrated with GPRS, DTMF and other functions.
It also supports DTMF. When enable the DTMF function, get the character feedback converted from the pressed button during the call, which can be used for remote control.
It is controlled by the AT command, you can directly start the function through the computer serial port and Arduino motherboard.
The SIM800C GPRS shield has a built-in SIM800H chip from SIMCom, with good stability.


Specifications

  • Power Supply <Vin>: 7-12V
  • Low power consumption: 0.7mA current in sleep mode
  • Low battery consumption (100mA @ 7V-GSM mode)
  • GSM 850/900/1800/1900MHz
  • GPRS multi-slot class 1 ~ 12
  • GPRS mobile station class B
  • GSM phase 2/2 + standard
  • Class 4 (2W @ 850/900 MHz)
  • Class 1 (1W @ 1800 / 1900MHz)
  • Controlling via AT command
  • USB /Arduino control switch
  • Serial baud rate self-adaption
  • Support DTMF
  • LED indicator for power supply status, network status and operating mode.


Technical Details

  • Dimensions: 77mm x 52mm x 27mm
  • Weight: 26g
  • Antenna length: 180mm

Test Code

1)For default serial ports RXD(D0) and TXD(D1): call up

************************************************
void setup()
{
  pinMode(13, OUTPUT);   
  pinMode(9, OUTPUT); //D9 is SIM900 turn on pin
  digitalWrite(9,HIGH);
  delay(1000);
  digitalWrite(9,LOW);
  delay(15000);
  Serial.begin(9600);
}
 
void loop()
{
  Serial.print("ATD15812345678;\r");//15812345678 your dialing phone number
  delay(100000);
//  Serial.println("ATH");
  delay(200000);
}

How to Use

1.Burn the above code onto keyestudio V4.0 board, stack shield on it, and connect SIM card(support 2G internet), Ethernet cable and earphone to shield.

2.Connect the jumper caps of shield to D0 and D1. DIP switch is dialed to EXTERN end, V4.0 board and shield are provided with power, alternatively, dial to ARDUINO end to supply power for V4.0 board which also provides power for shield.

3.The PWR LED of V4.0 board stays on, long press“To Start” button, then release button when the STA LED is always on and NET LED flashes.
4.Wait for 1 or 2 minutes and dial number 15912345678, after connection, you could call up by earphone or cellphone.
