(Same as the Trackbox by the looks of it) I was looking at the ATmega128 due to the two serial ports, but seems like overkill. Only just started looking at AVR and yet to get my hands dirty, could you use a AT2313 which seem quite popular? Nice project, I was thinking of doing the same thing with an old gps and a gsm modem.

I am using the ATmega8 (8k flash, 1k SRAM) which is sufficient until now. Communication is done with a hardware and a software serial port. One is attached to the modem, the other, for debugging and monitoring is attached to my PC, so you don't have to have 2 hardware UARTs.

And you wouldn't need anything at all for RXD if the output is true 2.2V since that reads as logic high for most 3.3V inputs. However, I can't read the schem very well because the labels are too small so I'm guessing at what you did.

This is what you need to do: 1) Insert a SIM card 2) Write a python script to get the GPS position 3) setup the module to boot the python script (AT#ESCRIPT = "gps_sms.py") 3) send the GPS position via SMS through the python script I did this last week with the same module for another purpose. ;) All you really need for this circuit is a power supply / charger You don’t need a uController, the Telit module has Python built-in.

Using embedded Python would save the extra cost / complexity of a separate microcontroller. However developing using Python can be tricky (no easy debugging capability) - the only reliable way seems to be to use the Python Debugger add-on hardware module from Round Solutions (which is not cheap). Also Python does not include support for floats, and only has the following modules: imp, marshal, md5, sys (no math etc).

This is certainly a different option than the one I'm thinking of doing. My method will be to use off the self equipment: ham radio, GPS, special radio modem (called a TNC). Pros: easy, off the shelf system (I already have most of the pieces) Cons: can be pricey; requires ham radio license (I have) A key advantage of this system is the integration with web-based mapping. I imagine this can be done with your system as well, though. Good going. Great idea and very educational! This is great. This is certainly a different option than the one I’m thinking of doing.

But your are on your own to migrate the code to the PIC, which should not be a real problem. Google Maps is not accessed directly. The module sends an SMS with a link to Google Maps to your email address. If you open the email and click the link, Google Maps will open and show your position. BTW: I am currently working on a Python version, which looks quite good so far, sending of SMS works already. Next thing is using GPRS instead of SMS. Using the built-in Python makes the external controller obsolete. Hi thomas,
sure, you can use a PIC instead of an AVR. But your are on your own to migrate the code to the PIC, which should not be a real problem.

Google Maps is not accessed directly. The module sends an SMS with a link to Google Maps to your email address. If you open the email and click the link, Google Maps will open and show your position.

BTW: I am currently working on a Python version, which looks quite good so far, sending of SMS works already. Next thing is using GPRS instead of SMS. Using the built-in Python makes the external controller obsolete.

Is this right to connect TX (PB0), RD (PB1) and GND connections directly to Serial DB9 connector?

This converter uses a FTDI chip but any other should do as well. So RX, TX and GND should be connected to such a converter. Every crystal will work, but you may have to check timings and baud setting again. Cheers, Alex Hi ideree,

I build the circuit and I am in the uploading firware process, and I have some doubts. These are the tools/kit I am using: AVR Studio 4.13, STK500 AVR Flash MCU Starter Kit, and the Mfile for AVR-GCC ver 2.7: 1. Is there any way to see a sample of a filled beacon file (C Type) to compare it with my entries? I found all the "EDIT THIS" areas, but I want to make sure I am using the right parameters and format information. 2. Once I have customized my own information in the beacon file (C Type), do I need to compile this file with the others files too? (suart & uart (C & H type), and beacon (Microsoft Schedule and Application type). 3. If I need to upload the previous files, do I need to use the flash section in the AVR Studio software for the beacon (Ctype file), and the EEPROM section for the other files?

For example, can it handle an interrupt that is raised due to input from serial port>? Thanks Hi, i am wondering whether the telit module can do interrupt handling routines like microcontrollers.

But it should be possible, I think I read something about cameras attached to the GM862 in the documentation. Cheers, Alex Hi Dan,

You could use a microcontroller to fetch the GPS data and send it via your MC39i. You may want to take a microcontroller that has two serial port, e.g. ATmega32. HTH. Cheers, Alex Hi jorge,

This converter uses a FTDI chip. - So in such case do you have your own driver built-in in your USB-to-RS232 converter? And what about terminal operation when terminal is not connected to PC. - Can i send a message to another mobile phone number stored in EEPROM of ATmega8-16PU? And i am going to use this device in Mongolia, which country located between Russia and china. - So, is there any reason that i can't be using this device in Mongolia? Regards, Ideree Hi, Alex

It looks like a serial connection to the controller. Just attach RX and TX to the controller. The connection from the converter to the PC is established with a driver that enables a virtual com port. You can download these drivers at FTDI, http://www.ftdichip.com/Drivers/VCP.htm Sending an SMS to another mobile phone should be possible, if you tweak the source code. I don't see any reason, why it shouldn't work in Mongolia. I assume you have GSM coverage most of the time. Cheers, Alex Hi Ideree,

First I have to say that I am not good at programming but i really wanna build a device as you built. And I'm hardly trying to make it working. I've finished to assemble all elements along with your guidence, and changed all the settings in your source code as you signed as EDIT THIS. And I have compiled all .c and .h codes and built a hex file. So i'm gonna write this file to Atmega8. - So I'd like to know how to use this source code and is it possible to send a message to another phone number instead of connecting device to PC? - If it is possible i can use your source code and program ATmega8 and build a device as you have, and turn it on by plugging power supply than device will send a message to another phone number from anywhere and anytime, without need of using PC. As I mention that this source code you made is possible to send a message to another phone and If I connect device to PC, the device can be controlled by PC. - AM I RIGHT? Please help me to finish this project successfully. Best regards, Ideree Hi, Alex

Sorry. You will have to learn this to adopt this project to your needs. You can modify the sms_gateway string to a number of your choice. And then have a look at the google_maps_P string. This is the formatted message that gets send. Further you have to adjust the main method to acquire the gps position and set it out with the SMS. If you have any further questions you can drop me an email, alex at this domain. Cheers, Alex Hi Ideree,
