Hello.
I'm developing a vehicle tracking system and one of the ways I can do this is with a arduino that gets the coordinates of the vehicle and sends it to a server through 3G with the GSM module.
I already have the server working with a SOAP web service, this was intended to work with a smartphone as gps tracker but now we want to try it with the arduino.
My question is: Based on your experience, which are the best ways to send coordinates to the server using GSM and web services? or I have to change something in the server?
I haven't decided which modules to get so you can suggest which are the appropiate
Thanks
