Send Sms Modem Php
I currently use mobile broadband as my primary Internet connection and this worked great on my Linux PCs for a while. The GSM modem I'm using every day is good old Huawei e220, but there is one aspect of this great hardware device I haven't used on my Linux PCs, and that is sending/receiving SMS messages. In this article I will show you how to send and receive SMS messages using GSM modem or phone on Ubuntu Linux PC.Lets begin. We don't really want to enter our administration password every time we want to send SMS message, so first thing we must do is to add our selves to the dialout user group. All members of this group have permission to use modem-like devices on Ubuntu system. This is how we do it. Sudo apt-get install gammu wammuBefore configuring our modem we must know a few things about it.
First thing you should do is go to the and find your GSM device. In this how to I will use my Huawei e220, with Gammu phone database page. On this page I've found first data we need to configure Gammu, the connection parametar that is at19200 in my case.
GSM modem (SMS) app (we can find this app on playstore check further details here) Laptop with php and mysql installed; There two sections first for sending and second or receiving so let’s start. Sending FREE SMS. For sending SMS from your project you need to create URL with required parameters. PHP sample - Send SMS text through a COM/USB GSM modem. The ActiveXperts SMS Component is a software development kit (SDK) to enhance an application or script with SMS or Pager functionality. SMS messages can be sent/received using a GSM modem, an SMPP provider or an HTTP compliant SMSC. I'm currently have a problem using PHP in order to create a form that has the capability to send sms by using GSM modem, by the way, the modem that i'm using right now is Huawei E173 Broadband.
You should obtain the connection parameter for your GSM device on its Gammu phone database page.Also you must find your GSM device entries inside /dev directory. You will recognize this entries because they usually start with 'tty' prefix. On my hardware this device entry is named ttyUSB0 and ttyUSB1. You can also check dmesg this way. Gammu-configHere's how you will setup your hardware with port ttyUSB0 and connection parameter at19200 I'm using for my Huawei e220 GSM modem:After you set configuration options you can save changes and you will get Gammu configuration file.gammurc file inside you home directory. You can also save this file for future use once you are sure that configuration it contains is correct.Important notice: Network manager has tendency to lock your GSM device once you start your GSM Internet connection. The device stays locked even after you disconnect so you must make sure that right click on Network manager - Enable mobile broadband option is unchecked before you use Gammu.
If this option is enabled you will get permission denied errors from Gammu.After we got that right I will show you how to check your SIM card messages the CLI way and how to start the GTK Gammu GUI called Wammu. To view all messages on your SIM card using CLI you can use something like this. Gammu getallsmsFor more about CLI usage you can check Linux manual pages usin man gammu command. To send and receive SMS messages using you GSM device you can also use GUI frontend to Gammu called Wamu.
You will find this program by navigating to the Applications - Accessories - Wammu. Then you can go to Phone - Connect. If the connection to the modem is successfully established you can use Retrieve menu to get messages or contacts from your SIM card and Create menu to send new SMS messages. If connection couldn't be established then you need to double check port and connection parameter you have used to configure Gammu. ↓. MoezHi Marko,I am currently working on my Project. It is about to use GSM modem or mobile phones that supports AT-Commands to send and receive SMS’s from people.
I just want to inquire about following things:-1. Which GSM modem will be perfect for the above description and will use AT-commands.2. Can we change the program of GSM modem depending on our requirements.3. Which mobile will support sending and receiving SMS and the ability to connect to the PC.4.
If we use a program to send and receive SMS, can we apply this code/program on our GSM modem or phone to change our requirements.Please, please, please reply me aas I am waiting for your response.Also please give me your id. I want to talk to you in detail as I am very much confused.Thanks.
↓.Hi Jose, with Network manager you can’t do that because it instructs pppd to lock device after your connection is first dialed. I haven’t tested this use case but theoretically by using pppd without network manager you could omit “lock” param in your so called peers file where you specify connection options and then your serial device wouldn’t be locked.Here’s my guide on dialing without Network Manager on Debian based distros: wrote another one for RHEL based distros if you’re RHEL/Fedora person. All of this would actually be very interesting to test.

SagarHi Marko,We are working on a project which is a blend of image processing and communication.We have done with the image processing part and now we are facing problems in transmitting text file as sms using gsm modem.We plan to have two way communication between a machine and a programmable board(pandaboard) both running on Linux platform, using the established gsm network.So, our difficulty lies in transmitting a txt file consisting of symbols which is the part of our image processing program.
Gsm Sms Modem
Queries are like:1)How to include the path of the output file(text) in the program?2)How to configure a gsm modem in our main program for this purpose?3)How we can include AT commands in our program that will call gsm modem to send the specified file? ↓. SagarThanks once again.Above program does initialization or what??My job is to operate modem to send SMS from text file automatically.
I don’t want to instruct it every time by typing AT commands. The only thing I want to do is to include set of AT commands required in my C code only with path of text file from which I have to get message body and send it to predetermined mobile no which also can be defined itself in the code.
So this is my difficulty. If you can reply to this with appropriate flow. ↓. AuthorThis code initializes your modem by sending AT command, when modem replies with OK this means it is ready to receive your commands.
AT commands are called “AT commands” because AT is initial command. If you are using C programing language you will need to go down to AT commands because I don’t believe someone made abstraction library for this. Also set of supported AT commands isn’t identical to all modem hardware manufacturers so I don’t believe it is possible to make such library. There is no easier way to do what you need and this isn’t difficult at all especially if we’re talking about C programming language.
You need to append a r to the end of each command rather than an 'OK'. The 'OK' is the response you expect to be returned by the phone.Use a terminal program 1 second delay1 second delayThe modem should respond with 'OK'Type AT+CMGF=1press enter keyModem will repond with 'OK'Etc.It is possible your phone does not support SMS text mode only pdu modeType at+CMGF=?Type enter key, if the response is at+CMGF (0,1) it supports both if (0) then pdu only. You will have to enter the SMS message in pdu mode.There are plenty of examples on how to do this. You need to append a r to the end of each command rather than an 'OK'.
