Usage
Hardware installation
1.Insert an Micro SIM card to SIM Card Holder
6 Pin Holder for SIM Cards. Both 1.8 volts and 3.0 volts SIM Cards are supported by SIM5360E - the SIM card voltage type is automatically detected.
2.Connect the Antenna
A miniature coaxial RF connector is present on the SIM5360E 3G Shield board to connect with a MAIN_Antenna. The connector present on the SIM5360E 3G Shield is called a U.FL connecto.The GNSS_Antenna supplied with the GPRS Shield has an SMA connector (and not an RP-SMA connector) on it.The connection topology is shown in the diagram below:
3.Plug to Arduino/Crowduino
The GPRS+GSM+GPS Shield, like any other well designed shield, is stackable as shown in the photo below.
Turn on the SIM5360E 3G shield
There is two ways to turn on the SIM5360 3G Shield.
1. Turn on through Hardware. Press the the 'POWERKEY' for few seconds until Power-on indicator(Green) is on.
2. Turn on through Software. If the JP is soldered,run the following code, the SIM5360E will POWER on or POWER off.
int Powerkey = 9;
void setup() {
pinMode(Powerkey, OUTPUT); // initialize the digital pin as an output.
power(); //power on the sim5360 or power down the sim5360
}
void loop()
{
}
void power(void)
{
digitalWrite(Powerkey, LOW);
delay(1000); // wait for 1 second
digitalWrite(Powerkey, HIGH);
}
Serial Port(UART) Communication
The SIM5360 3G Shield is used UART protocol to communicate with an Arduino/Arduino clone; Users can use jumpers to connect (RX,TX) of the shield to either Software Serial(D8,D7) or Hardware Serial(D1,D0) of the Arduino.Detailed information is showed as the following picture:
Power Down the GPRS Shield
The GPRS Shield can be turned off by following ways:
- 1, Normal power down procedure: Turn off the GPRS shield by using Hardware Triger; Press the ON/OFF Button about one seconds.
The power down scenarios illustrates as following figure:
The following code is power down subroutine for Arduino if using software triger:
int Powerkey = 9;
void setup() {
pinMode(Powerkey, OUTPUT); // initialize the digital pin as an output.
power(); //power on the sim5360 or power down the sim5360
}
void loop()
{
}
void power(void)
{
digitalWrite(Powerkey, LOW);
delay(1000); // wait for 1 second
digitalWrite(Powerkey, HIGH);
}
- 2, Normal power down procedure: Turn off the GPRS shield by sending AT command "AT+CPOF" to SIM5360 module.
When GPRS Shield power dowm in Normal power down procedure, the procedure lets the SIM5360 log off from the network and allows the software to enter into a secure state and save data before completely disconnecting the power supply. Before the completion of the power down procedure the SIM5360 will send out result code:
NORMAL POWER DOWN
- 3, Over-voltage or Under-voltage Power Down: The module software monitors VBAT voltage constantly.
①If the voltage ≤ 3.5V, the following URC will be reported:
UNDER-VOLTAGE WARNNING
②If the voltage ≥ 4.3V, the following URC will be reported:
OVER-VOLTAGE WARNNING
③If the voltage < 3.4V, the following URC will be reported,and the module will be automativally powered down.
UNDER-VOLTAGE POWER DOWN
④If the voltage > 4.4V, the following URC will be reported,and the module will be automativally powered down.
OVER-VOLTAGE POWER DOWN
- 4, Over-temperature or Under-temperature Power Down: SIM5360 will constantly monitor the temperature of the module.
①If the temperature > +80℃, the following URC will be reported:
+CMTE:1
②If the temperature < -30℃, the following URC will be reported:
+CMTE:-1
③If the temperature > +85℃, the following URC will be reported,and the module will be automativally powered down.
+CMTE:2
④If the temperature < -40℃, the following URC will be reported,and the module will be automativally powered down.
+CMTE:-2
When the GPRS Shield encounters POWER DOWN scenario, the AT commands can not be executed. The SIM5360 logs off from network and enters the POWER DOWN mode, only the RTC is still active. POWER DOWN can also be indicated by STATUS LED(Blue), which is off in this mode.
Note:
- To monitor the temperature, users can use the “AT+CMTE” command to read the temperature when GPRS Shield is powered on.
Upload Sketch to Arduino
The following sketch configures Arduino/Arduino clone as serial link between PC and the GPRS Shield(Jumpers on SWserial side). PC would need a serial terminal software to communicate with it - Window's built-in HyperTerminal, Arduino IDE's Serial Monitor, Serial Terminals(sscom32) or Bray++ Terminal.
After uploading the sketch to the Arduino board, press the ON/OFF button on the GPRS Shield to turn it on; Now you can see what you get on the serial terminal and the status of the three indicator LEDs, then communicate with your Shield.
//Serial Relay - Arduino will patch a
//serial link between the computer and the GPRS Shield
//at 19200 bps 8-N-1
//Computer is connected to Hardware UART
//GPRS Shield is connected to the Software UART
#include <SoftwareSerial.h>
SoftwareSerial GSMSerial(7, 8);
void setup()
{
GSMSerial.begin(19200); // the GPRS/GSM baud rate
Serial.begin(19200); // the GPRS/GSM baud rate
}
void loop()
{
if(Serial.available())
GSMSerial.print((char)Serial.read());
else if(GSMSerial.available())
Serial.print((char)GSMSerial.read());
}
Note:
- The "AT" or "at" prefix must be set at the beginning of each Command line. To terminate a Command line enter <CR>.

A Simple Source Code Example
The demo code below is for the Xduino to send SMS message/show message/delete message/dial a voice call . It has been tested on Arduino Duemilanove but will work on any compatible variant, plesse note that this sketch uses the sorfware UART of ATmega328P. please follow the following steps for running this sketch.
- With the 3G Shield removed, download this sketch into your Arduino.
- Disconnect the Xduino from USB port to remove power source.
- Set the Serial Port jumpers on the 3G Shield in SWserial position, to use the Soft Serial port of Arduino.
- Connect the antenna to the 3G Shield and insert the SIM Card.
- Mount the 3G Shield on Arduino.
- Connect the Arduino to the computer by USB, and fire up your favorite serial terminal software on computer, choose the COM port for Arduino, set it to operate at 19200 8-N-1.
- Type command in the terminal to execute different function, threr are 5 functions in the demo:
- If you input 'Q' in the terminal, the program will execute GetSignalQuality(),it will show the signal quality,
- If you input 'T', the demo will send a SMS message to another cellphone which you set(you need set the number in the code);
- If you input 'S', the demo will listing all SMS message ;
- If you input 'E', the demo will delete a SMS message ;
- If you input 'D', the program will dial a call to the other cellphone that you set(it is also need you set in the code );
- If the program returns error in the terminal after you typed the command, don't worry, just try input the command again.
/*Note: this code is a demo for how to using 3G shield to send sms message, show message,delete message, dial a voice call.
The microcontrollers Digital Pin 7 and hence allow unhindered
communication with 3G Shield using SoftSerial Library.
