GSM Modem Kurulumu « Murat Çileli

Cep telefonunuza gelen “başlıksız” (yani normal bir cep telefonu numarasından gelen) mesajları bilirsiniz. “Bilmem ne için son fırsat” ya da “Kredi kartı borçlarınızı taksitlendiriyoruz” gibi… Bu tür toplu gönderimleri yapanlar, daha düşük maliyetli olması için bir “SMS Gateway” kullanmak yerine gönderimlerini SIM kart üzerinden yapıyorlar. İşte bu yazıda, bu tür toplu SMS gönderimlerinde ve bir çok ticari alanda yaygın olarak kullanılan altyapıya “kuşbaşı” bakacağız.

Herşeyden önce bir GSM modem’e ihtiyacımız olacak. Piyasada çok sayıda ve farklı fiyat aralıklarında GSM modem bulabiliyorsunuz. Sahip olduğu özelliklere göre fiyat tabi ki değişiyor. Eğer amacınız yalnızca SMS göndermekse giriş seviyesinde bir modem de işinizi görebilir. Bendeki Siemens’in TC35 modeli, aynı zamanda sesli arama yaparken kullanabileceğiniz mikrofon girişini ve ses çıkışını da içeriyor. Modemin e-Bay’daki fiyatı 100 USD 30 USD civarında bildiğim kadarıyla.

Piyasadaki bir çok modelin bağlantı arayüzü RS-232’dir. Yeni nesil bilgisayarlarda ve özellikle dizüstü bilgisayarlarda seri port girişi olmadığından bir adet RS-232 / USB çeviriciye de ihtiyacınız olacak.

GSM modem’inizi bilgisayarınıza bağladıktan sonra, eğer ürünle birlikte bir driver ya da kurulum dosyası gelmişse kurulumunu yaparsınız. Genellikle Çin malı ve giriş seviyesindeki ürünlerin yanında driver gelmiyor. Bu durumda Denetim Masası > Telefon ve Modem menüsünden, cihazınızı “Standart 56.000 Bps Modem” olarak tanıtmanız yeterlidir.

Eğer üretici tarafından aksi belirtilmemişse, yine Telefon ve Modem menüsünde, “En Yüksek Bağlantı Hızı” (Baud Rate) değerini 9600 olarak ayarlayın.

Acaba cihazımız çalışıyor mu? Bunu test etmenin bir çok yolu var. Biz bir terminal yazılımı olan PuTTY ile modemimize bağlanıp, cihaz üzerinde sorgulamalar yapacağız.

PuTTY ekranında, “Connection Type” seçeneğini “Serial” olarak belirledikten sonra, “Serial Line” bölümüne cihazın bağlı olduğu portu, “Speed” bölümüne biraz önce belirlediğimiz Baud Rate değeri olan 9600’ü yazıyoruz ve “Open” diyoruz.

Eğer bağlntımız başarılıysa, siyah ve boş bir ekran bizi karşılayacaktır. Terminal penceresinde “ATI” yazarak enter’e bastığımızda cihazın marka / model bilgisi bize dönecektir. Bu da demektir ki cihazımıza başarıyla bağlandık ve cihaz komutları başarıyla işliyor.

Eğer SIM kartınız takılıysa, modemin GSM komutlarını işleyebilmesi için PIN kodunu girmeniz gerekir. Bunun için modeme “AT+CPIN=0000” komutunu gönderiyoruz. Buradaki dört haneli rakam, SIM kartınızın PIN kodudur.

Eğer “+CPIN: READY” cevabı geldiyse, artık ortamlara akabilirsiniz demektir.

Elbette kimse bir GSM modem’i PuTTY ile kullanmak için almaz. Genellikle M2M yani makineden makineye sistemlerde kullanılır ve terminal kısmında özel yazılımlar bulunur. GSM modem’ler; toplu SMS gönderiminden, otomatikleştirilmiş sesli aramalara, benzin istasyonlarındaki pompalardan, bankamatik cihazlarına  kadar her alanda kullanılıyor.

Eğer kendi yazılımınızda GSM modem kullanacaksanız, aynı komut setlerini yine seri port üzerinden göndererek modeminizi yönetebilirsiniz. GSM modem ile yapabileceğiniz tüm işlemleri Hayes / AT komut setini inceleyerek öğrenebilirsiniz. Kullandığınız platforma ya da programlama diline bağlı olarak, işinizi kolaylaştıracak çeşitli seri port kütüphaneleri de mevcut.

GSM FAQ

The focus of this GSM FAQ is on GSM modem / module topics. The AT command set of the most GSM mobile phones is eqaul, so that is users and developers of software for GSM phones can use it too.

Please feel free to have a look at GSM modem first steps also.

Q. My GSM modem  appears to be dead. I can  get no response from the serial interface. Why?

A. Firstly, make sure that the green ignition line in the power supply lead is  connected to the positive supply. Then try connecting to your PC serial port and  using Windows Hyperterm to connect to the unit. Hyperterm comes with Windows XX, but may  not be installed by default depending on the options selected when Windows was installed.  If "AT" is entered in Hyperterm, the unit should now respond with  "OK".Remark for GSM phones: Often GSM phones has a software modem and you not be controlled with any Terninal software directly. You have to use the soft modem drives of your phone then.

Q. My GSM modem was working, but now the serial  port has locked up. How do I get out of this state?

A. There are various reasons that the modem may get into this state, but the more  common ones are power supplies dipping below spec, flow control set incorrectly, and  commands being sent to the modem at a greater rate than that at which they can be  processed.

Q. What flow control does the GSM module expect on the 9 way D  type RS232 interface?

A. Consequently,  it is recommended that you explicitly specify flow control as part of the initialisation  process. AT+IFC=0,0 will turn flow control off, AT+IFC=2,2 will turn hardware flow control  on. This command is described in V25ter, paragraph 6.2.12. 

Q. How can I get hold of the GSM standards?

A. V25ter can be downloaded from International  Telecommunication Union web site (www.itu.int).  GSM07.05 and GSM07.07 can be downloaded  from the ETSI website (www.etsi.org).

Q. Which GSM networks support a GSM modem?

A. The GSM modem on this website work at 900 MHz , 1800 MHz and 1900MHz. For service providers in other  countries check with GSM Association  website (http://www.gsmworld.com) which gives the capabilities of every network worldwide.  Also check your roaming agreement as just because the network supports any given feature,  this does not mean that the roaming agreement includes it. Please check the SMS roaming careful too, because it could be that there is a roming for voice call and not for SMS.

Q. Any command that I type to the modem returns with  "ERROR". Why?

A. The default command termination character is a Carriage Return. If the application  software is sending Carriage Return, Line Feed to the modem, the Line Feed character will  get prefixed to the next sequence sent to the modem. Any command starting with a Line Feed  character will generate "ERROR" as an error message.

Q. The serial interface works OK, but I cannot dial out. Why?

A. First check that there are no call bars or passwords set up on the SIM card. This  can be done with the AT+CPIN and AT+CLCK commands, but it is easiest to put the card in a  normal mobile phone and check the status on the phones display. Assuming that there are no  call bars or passwords, check that the modem is logged onto a network with AT+CREG. No  network, no dialling of course. If the network is there, check signal strength with  AT+CSQ. This needs to return a value of 12 or better for a reliable data or voice  connection. Please not that ATD123456789 starts a data call and a ATD123456789; starts a  voice call. The semicolion on the end of the string is the small difference between a  voice call and a data call. If you start a data to a  a GSM unit with a SIM card  without dta subscribtion, then the answer is ervery time "No Carrier".

Q:  I have the fax and data subscription, but there is no transfer. Why?

When  the service is theorically activated from the provider, it's good to evaluate  the technical activation too. The first thing to check is the releise of two  phone numbers. If we have both of them, we can proceed with a simple test:  from a regular phone dial the fax or data GSM number. If we hear the classic  whistle of the modem and the "fax or data call" appears on the cellular  display, then we know that the service is correctly activated (the problem  depends from other factors). If we hear, instead, the stand-by signal without  answer, then we will have to call the provider to check the activation. The  problem is solved this way 40% of the times.

Q. How do I check to see when an SMS message arrives?

A. With the command AT+CNMI you can switch the GSM modem in a mode that you will give  you a "String" with every incoming SMS. This command is described in paragraph  3.4.1 of the GSM 07.05 specification. Alternatively, the command AT+CMGR can be used to  poll the modem for new messages. 

Q. How do I know if an incoming call is voice, data, or  fax?

A. Turn on extended ring indication, AT+CRC=1. This command is detailed in paragraph  6.11 of GSM07.07 and gives a more verbose output on incoming calls. The default factory  setting of GSM module is AT+CRC=0.
