Development

You can use GSM library to test, https://github.com/Microduino/Microduino_Tutorials/tree/master/Microduino_Libraries/_03_Microduino_GSM_SIM800L

Application

Send short messages using the example program.

Preparation

  • Hardware：Microduino FT232R, Microduino Core, Microduino GSM, USB cable or lithium battery；
  • Software: GSM library, Arduino IDE (version 1.0.3 and higher)；
  • Uncompressed the zip folder to libraries of Arduino IDE；
  • Connect the Microduino FT232R and PC using USB cable to download program and monitor the serial port；
  • USB cable or li-ion battery to charge the Microduino GSM module and press the power button for a long time to activate Microduino GSM for about 4 seconds. That the power-on indicator goes on shows a successful start.

Debugging

  • Download the test program:Github Download
  • Open the test program, and then you need double check the following parameter:
    • “#define NUM "13667928xxx"”：Need change to the number that receive message.
    • “#define SMS_CEN "13010720xxx"”：Your message center for you own mobile phone number, you can find it in your phone. It isn't the necessary. If hit an issue during send a message, you can try it.
  • Compile the program, select the board type "Microduino Core+ (Atmega644P@16M,5V)", download directly:
  • Open the serial monitor, set the baud rate is 9600:
    • Input "t", to send the message "wiki.microduino.cc";
    • Input "d", you can make a call, but can't finish a normal call, because no the speaker and microphone;
    • Input "h", you can submit a HTTP request to get some data from network;
    • Input "s", you can send the sensor data to network.
  • If using Microduino-Core to debug, you need the soft serial port(TX1, RX1)
  • If you use the Microduino Core to debug, must use the Software Serail (TX1,RX1)
    • Use the Software Serial library
#include <SoftwareSerial.h>

SoftwareSerial mySerial(2, 3); // RX, TX
    • Change the Serial1 to mySerial, it should be ok。
  • If you use the Microduino CoreUSB to debug, you only need to change the serial to serial 0 (TX0,RX0).

FAQ

  • Can this module be used to make a voice call? Is a pin available for voice?
    • This module can’t be used to make a voice call, because it doesn’t have the required pin.
  • Does this module work with Core+ module?
    • Yes.
  • Does this module use Arduino GSM library?
    • Yes.
  • Does this module work with 3G?
    • No, it only supports GPRS and GSM.
  • How is this module powered?
    • There are two methods:
      • Using the USB port attached to the module with a 5V, 1A power supply (Voltage 5V, Amperage 1A)
      • Using a 3.7V Li-ion battery attached to the module

'The BM module can power the Core module and other modules, such as the 10DOF. However, use of the BM module to power the GPRS/GSM module is not suggested due to its significant power consumption.
