*Open SendSMS test program in the examples;
+
*Download the test program:
*After it gets compiled successfully, just select the board "Microduino Core (Atmega328P@16M,5V)" and download directly;

**Open the serial monitor(The serial monitor is set to the format of "Newline" and "Enter" ), set the baud rate, and the "SMS Messages Sender" will be printed;
+
*Open the test program, you need double check the following parameter:
**You need to wait for Microduino GSM module reading SIM card about 10 seconds. If that goes well, "GSM initialized" will be displayed and a note will pop up to remind you to input one number.
+
**“#define NUM "13667928xxx"”:Need change to the number that receive message.
**After the input, just press the Enter key, it will remind you to write your 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 nessary. If hit an issue during send a message, you can try it.
**Just press the Enter key after the input, the sending process will be displayed and then you can see "COMPLETE". .

**Input "h", you can submit a HTTP request to get some data from network;
 +
**Input "s", you can send the sensor data to newtork.

**Use the SoftwareSerial library
 +
<source lang="cpp">
 +
#include <SoftwareSerial.h>
 +
 
 +
SoftwareSerial mySerial(2, 3); // RX, TX

Document

Development

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

Note:This library only supports Microduino-core.

Application

Sending short messages through the example program in the library.

Preparation

  • Hardware:Microduino FT232R, Microduino Core, Microduino GSM, USB cable or lithium battery;
  • Software: GSM library, Arduino IDE (version 1.0.3 and higher);
  • Uncompress 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:

https://github.com/Microduino/Microduino_Tutorials/commit/25a821ba8894fb02d4b1560c9912450cc353b875

  • Open the test program, 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 nessary. If hit an issue during send a message, you can try it.
  • Compile the program, select the boardy 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 newtork.
  • 如果你使用Microduino Core调试,你需要用到软串口(TX1,RX1)
  • If you use the Microduino Cort to debug, must use the SoftwareSerail (TX1,RX1)
    • Use the SoftwareSerial 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 serail to serial 0 (TX0,RX0).

FQA

  • Does this module can be used to make a voice phone? Any voice pin was picked out?
    • This module can’t be made a voice phone, because it doesn’t have pin.
  • Does this module can work with Core+ module?
    • Yes.
  • Does this module can use Arduino GSM library?
    • Yes.
  • Does this module can use to 3G?
    • No, it only supports GPRS and GSM.
  • How to power on this module?
    • There are two methods:
      • Using the USB on attached module to supply the power, the voltage is 5V and the current MUST lager than 1A.
      • Using Li-ion battery on attached module to supply the power, the Li-ion should be 3.7V.

BM module can power on the Core module and other module, such as 10DOF, but don't suggest to power GPRS/GSM module, because it is a big power consumption module.
