hello, i am newborn with this project, i want to do is send many message sms, I have windows application .net, i have firmadata.dll, but I have big doubt, what type hardware i need, what type of modem, what type of arduino board and perhaps something else, could you tell me what else?, the point is send 50 or 60 messages (different numbers) to clients telling them, here is your product or something else.
Thank you
I do not know if this topic is right here
First you should think what modules there are and what their responsibility is. This is called functional decomposition.
One part will have the client database with the phone numbers, another part will send the SMS-es, yet another part will know who should got which SMS etc.
Thank for reply, look i am going to buy this,
i have a database sql server 2005, vb.net, the application but what hardware i need, i do not know if is necessary to buy that (Arduino-GSM-SIEMENS-TC35-SMS-Wireless-Module-UART-232), for a sample if you are going to do that project (send message sms) what you would need it
thank you
I don't understand why you would use an Arduino based olution for that ?
Does the computer with the .net application have internet access ?
Then it would be much easier (and probably cheaper) to use an online service that can take send the SMS mesages for you.
Well man, i am not looking for online service that can take send the SMS mesages, i want to do myself, but tell me the steps i have to follow, the situation is,I have application and i need to send text message (SMS) from that application
first youll need an gsm module which would be easy to control with arduino (this shield http://www.sparkfun.com/products/9607 provides gsm/gprs and can be controlled by an arduino via an serial interface but @ 100$ its kinda pricey)
after you get your module working you need to make a way to communicate with your arduino from the vb.net application easiest solution would be serial communication so you send the number from your application via serial to arduino , arduino sends a sms via serial with the gsm module
if you want to experiment a bit most older nokia phones offer the fbus protocol which allows you to control the phone with your arduino , you can read more here http://www.embedtronics.com/nokia/fbus.html - unfortunately on that page there isn't any code/schematic but its a starting point
hope this helps
Thank you Putyn, you hit on the target,
I found this one, look this link
and you say this one
which one do you recommend me?
another thing
I have to do some welding to join the parts so, remember i am newborn with this, i am strong on software but not on hardrware
Thank you for great help
I agree with MicMo, it would be much simpler to accomplish your project completely in software.
W/o gsm shield and arduino. Google "send sms online" , there is also services to translate e-mail to sms, so your application could be just MS Outlook.
I think,Magician and Mikmo do not understand the topic, the point is send 50 or 60 or N messages (to different numbers) to clients telling them, here is your product or something else, doing a click on button of my application, I do not want to pay nothing.
If you make an application you must put a value for the application to take value
You will have to pay more, if you do it in hardware.
Software - you pay if only there is no free
Internet web-html or E-mail >>to>> SMS gateway available in your country , or for specific GSM service providers.
Hardware - you pay for arduino + gsm shield + sim card (connection fee) + send sms fee ( or monthly payment plan ).
There is sql or whatever clients database running on your computer in both version.
Sending SMS with the shield is NOT free. you still need a SIM card and to pay for the subscription + for each SMS, unless they are free with he subscription.
Also a homebrew hardware solution is probably going to be less reliable than a software solution.
