I am a new member of this community and I would like to have some purchasing advise for my project.
GOAL: I need to develop a small device which will send an E-mail/SMS to a recepient containing GPS location. This should be done with the touch of a button. Battery life should be maximized so the device should be activated only when the button is pressed.
I think you will find very few people willing to jump into a discussion as your propose.
Because there are a million ways to implement this…the conversation could be endless.
You will need to decide the direction you want to take…and ask more specific questions based on that direction. Any other method of figuring it out, would be asking someone to design it for you. I would think people will not want to do this for free. They had to learn, so you will need to do the same, or pay someone to design it for you.
There are then all of the issues with running python on the Telit units, its fine but has serious pit falls.
I would recommend that you look through all of the relevant manuals before you spend your cash and decide if it is something you want to do or if its something you want someone to do for you.
The GM862 can be switched on with a push button, see the Hardware User Manual. You might be able to program it in Python to send a message then switch itself off. It might be easier to control it with an MCU, interface a push button to that, and use it to switch the GM862 on and get it to send the message.
I already have someone who’s in charge of the ¨Python part, so no problem on that issue.
The only issue I have is to know what I need to purchase in order to put together the “button” functionality? How is this done?
Thanx again for your replies…
I said that we have someone who’s in charge of the Python part (programming). The “only” thing we need to do is provide him with a device which can be connected to a computer for programming a script.
My question for the forum is what we need to purchase in order to make the device do what I described above.
I truly appreciate your help and I certainly don’t want to seem rude. But you aren’t helping that much by saying “this is difficult” and “you are stuck”.
I thought this forum also helps newbies in search for infi, if not, feel free to correct me and re-direct me to an appropriate platform/forum.
The problem is that this isn’t just a matter of buying a few components and wiring them together and suddenly when you push a button it sends the GPS coordinates to whereever it is you want them sent.
You’re going to need to write some code that will run on the microcontroller to make it wake up when the button is being pushed, then start the GPS unit, wait until it gets a satellite fix (which will take as long as a minute or so), then read the data from the GPS, then send whatever needs to be sent to the call phone module to send the IM with the data.
Just giving you a shopping list of components doesn’t come at all close to solving your problem.
The fact that you don’t understand this means that this is probably too advanced of a project for you at this time, and no one wants to offer to teach you all of the basics that you will need to learn before you are ready for it. We are happy to help newbies, but no one is going to design your project for you from scratch, which is basically what you’re asking for.
You’ll need to understand how they would work together, you need to learn to design a circuit board, you need to learn how to program a MCU, you need to learn the details of how the MCU needs to communicate with the GPS & GSM modules.
Frankly, if you need to have this done by the end of April, you’d better clear your calendar and be prepared to do a lot of learning between now and then. Sparkfun has some tutorials on embedded electronics, that would be a good place to start. Lesson one is at http://www.sparkfun.com/commerce/presen … owerSupply
I’m sorry of this sounds harsh, but someone has to say it.
