    GPS Tracking w/Text Messaging (with carputer on.)

    I know there is alot of discussion here about hooking up a GPS to a cell phone for operation with the computer off. I want to be able to send my GPS location but only need to do it with the computer on.

    So my theory... I have a US Cellular Razr which is Bluetooth enabled. I want to be able to connect to the Razr via bluetooth and send GPS corrdinates. I'm assuming I can use something like maps.google.com to display the maps and my location.

    Now, I can handle writting the GPS interface, I have code for this already in some programs I've written for my day job. I can also handle receiving the e-mail and processing the coordinates and stuffing them into a database. Maps.google.com is probably easy to manipulate. So how do I send a SMS message through bluetooth to my phone? and is there anyone doing this already?


    I have a couple of reasons for wanting this. I want a quick way for me to review where I've been and where I'm going. This is especially nice for figuring up my milage every month. I think it would also be a nice "cool" factor and my wife would be able to see where I'm at (my cell phone doesn't work inside some of my customer's offices.)

    How would your computer send an SMS to your wife? You didn't mention anything about how your computer will connect to the internet.

    One way you can proceed, if you use your phone as a modem for your carPC, is by running an SMTP server on your carPC. Have your own GPS application polling every couple of minutes for coordinates and sending a properly formatted e-mail via the SMTP server. The e-mail can contain a simple maps.google.com link that includes the coordinates for querying.

    Ex. http://maps.google.com/maps?q=37.771...&iwloc=A&hl=en

    Okay, you missed a couple of things. I don't want to use my phone for internet access. I want to utilize it's text messaging capabilities. I want to send a text message to an e-mail address say, [email protected]. On the server, that e-mail address will be piped to an application that will pick the coordinates up out of the e-mail and store them into a database. Then people can goto a page on my web server and can track me from there.

    I don't want to dial out to the internet because then I can't receive phone calls on my cell phone. The data is so little that a text message could easily handle the amount of data. And text messaging will work a higher percentage of the time than dialing up to the internet anyways.

    bob:

    Where is your "server"? Is it on the carPC?

    Take a look. I've seen a few bluetooth chat clients on the net. Not sure which profile they use. My guess would be that they use the LAN profile.

    Soooo, let me see if I understand. You will have your carPC create a message that will be sent to your phone over bluetooth. Then your phone will send this message as a text message. Am I getting this?

    Have you thought about the costs of this? I know with verizon each text sent over the 'plan' is $0.10.

    I think Motorola phone tools has a way to send SMS, I think Phonecontrol does it too, I don't know anything about coding it to work though.

    You could SMS the NMEA sentence and plot the information in the sentence which would include latitude, longitude and heading.
    Have you looked in the FAQ yet?
    How about the Wiki?



    Under normal circumstances, a signature would go here.

    Great example of an SMS app for PPC.

    Jahntassa's right about Phonecontrol. I never tried sending an SMS from PhoCo, but Zorro can you give some more ideas on how to proceed. I had completely forgotten about using AT commands to send SMS messages.

    This can be done for free and without a cell phone using APRS technology.

    It requires 3 items, a portable Ham radio, a device called a Tiny Trak II, and a GPS antenna. The data is sent via packet radio and put on a server that is tied to your Ham radio license ID that people can log into and see where you are.

    The only impediment is the Ham license, but it's a fairly low bar to get the basic license.

    Why would I want to do this, coverage for that is less than what it would be for my cell phone,not to mention a huge added cost!

    I have 3 dedicated servers at the planet in Texas. (http://www.ThePlanet.com)

    US Cellular 9.95 / month unlimited text messages.

    I'll have to look into that.
