GSM/GPRS/GPS

Latest GSM/GPS module from SIMCOM. SIM808 module is a complete Quad-Band (850/900/1800/1900MHz) GSM/GPRS module which combines GPS technology for satellite navigation.

The compact design which integrated GPRS and GPS in a SMT package will significantly save both time and costs for customers to develop GPS enabled applications. Featuring an industry-standard interface and GPS function, it allows variable assets to be tracked seamlessly at any location and anytime with signal coverage.

Mooduli kirjeldus on WIKI-s: SIM808 GSM/GPRS/GPS Module

Raadiomooduli laiendusplaadi tööle saamiseks tuleb viigule VBAT ana üsna täpselt pinge vahemikus 3.4 - 4.4 V. Nende väärtuste ületamine ühele või teisele poole põhjustab plaadi väljalülitumise. Viik VIO tuleb ühendada vastavalt jadapordi nivoole kas 3.3 V või 5 V siiniga. Plaadi sisse või väljalülitamine käib seal peal oleva lülitiga või vastava viiguga.

Üldiselt toimivad WIKI-s olevad näited ja ka SIM900 mõeldud SMS-ide saatmise näited. GPS tundus, et mingeid andmeid sai kätte. Bluetoothi näited vajavad lähemat uurimist.

Ultra compact and reliable design. This is a complete Quad-band GSM/GPRS module in a SMT type and designed with a very powerful single-chip processor integrating AMR926EJ-S core, allowing you to benefit from small dimensions and cost-effective solutions.

Featuring an industry-standard interface, the SIM900 delivers GSM/GPRS 850/900/1800/1900MHz performance for voice, SMS, Data, and Fax in a small form factor and with low power consumption. With a tiny configuration of 24mm x 24mm x 3 mm, SIM900 can fit almost all the space requirements in your M2M applications, especially for slim and compact demands of design.

Mooduli kirjeldus ja lihtsad näited on WIKI-s:

Wiki

Wiki näited on testitud ja töötavad. GPRS/GSM Shield v1.0 tuleb seadistada nii, et valitud oleks SWserial ja lüliti oleks asendis Xduino. Mooduli käivitamiseks tuleb vajutada lülitit PWRKEY.

Laiendusplaati võib kasutada ka järgmise Arduino teegiga:

GSM/GPRS & GPS Shield Library for modules using SIM900/SIM908

Teegis tuleb avada kõigepealt fail GSM.cpp ja muuta jadapordi viigud järgmiseks:

#define _GSM_TXPIN_ 7
#define _GSM_RXPIN_ 8

Seejärel võib proovida SMS-i saata:

#include "SIM900.h"
#include <SoftwareSerial.h>
#include "sms.h"
SMSGSM sms;
boolean started=false;
 
void setup() 
{
  //Serial connection.
  Serial.begin(9600);
  Serial.println("GSM Shield testing.");
 
  if (gsm.begin(2400)){
    Serial.println("\nstatus=READY");
    started=true;  
  }
  else Serial.println("\nstatus=IDLE");
 
  if(started){
    // Replace 37212345678 with the correct phone number
    if (sms.SendSMS("+37212345678", "SMS from Arduino"))
      Serial.println("\nSMS sent OK");
  }
};
 
void loop() 
{
 
}

Ultra compact and reliable design. The SIM900A is a complete Dual-band (900/1800 MHz) GSM/GPRS module in a SMT type which is designed specially for Chinese market, allowing you to benefit from small dimensions and cost-effective solutions. Featuring an industry-standard interface, the SIM900A delivers GSM/GPRS 900/1800MHz performance for voice, SMS, Data, and Fax in a small form factor and with low power consumption. With a tiny configuration of 24mm x 24mm x 3 mm, SIM900A can fit almost all the space requirements in your applications, especially for slim and compact demand of design.
