Hi I am trying to make an arduino into an SMS web router
I came up with this idea based as a way of utilizing the vast amount of text messages I have available on my mobile contract that I just don’t use, but I’ll get to that in a bit. I’ve done a few projects and built a small server with the Ethernet shield but I’m not that proficient with network protocol.
I’ve had a quick read through the forum and I couldn’t find anything that answered my questions if a forum thread exists that covers this subject that I’ve missed I would be grateful if you could point me to it.
What I want to do is to enable remote access to my network, using the GSM module to transmit data as SMS messages that are then reassembled at the other end with the arduino and Ethernet shield acting like a router that reassembles the data. The way I find this easiest to understand is to think of two of these routers acting like a bridge within my network with one module connected to my LAN setup and the other going with me, then I could access it anywhere I go that has a mobile signal (like my own privet internet
My network isn’t connected to the internet it’s a small LAN setup I primarily use for testing purposes
I am using the standard Ethernet shield with a micro SD card port, an arduino uno R3, and a GSM/GPRS shield http://www.ebay.co.uk/itm/221176159800?_trksid=p5197.c0.m619http://www.sainsmart.com/sainsmart-ethernet-shield-w5100-for-arduino.html
The thing that I need help on first is, is the arduino Ethernet shield even able to act in that manner, if so has anyone got any advice on where to start with the coding,. If it is not possible with the Ethernet shield than is it possible to create an invisible link in the network that simply forwards data anonymously appearing as a link straight to my computer.
Also does anybody have any recommended reading that could help with networking with the arduino? thanks.
