Writing software for a car-computer

[Siekmanski]

MARINUS/SIEKMANSKI,
You really come up with some great concepts. And,...this one is so practical.
...You should think seriously about franchising it,...you will probably become a billionaire,...and, some day run into Bill Gates,...who will ask: "Why didn't I think of that ???"

In my dreams hahaha...  nothing new here, most new cars have such computers built in.
If you want to buy such a system it cost you a lot, so i thought building one myself for fun.

Those mini itx mother-boards are very cheap, 80 - 200 euro and a 7" touchscreen 50 euro.
I have several FM-tuners stripped from old pci TV cards at home, they are easy controlled with a 2 euro microcontroller.
Then i need 4 audio amplifiers for front and rear speakers.
At last an OBD2 connector, some resistors, caps, transistors, diodes, voltage regulator and a FTDI chip for the communication.
This is all the hardware i need in this project.
Some of those parts i have ordered in China.

Maybe i build in a neuralyzer which i can use on cops if i'm caught speeding.... 

I have read a lot about BlueTooth ( and OBD2 ) protocols the last days and all is still a bit vague.
This weekend i'll try some coding and hope to get in contact with my mobile phone via a BlueTooth connection.

You remind me of a guy I was in High school with. We were both in electronics class,but he was that guy that went above and beyond,I think he could have taught the teacher. I have no doubt he has invented a lot of things since we were in school,he was just that guy who could come up with stuff no one else could. :t

I'm struggling my way thru the Bluetooth apis.
So far it only searches for Bluetooth devices and i hope that it filters out the smart phones.

It would be nice if you guys with a smart phone can help me out to test if it works as expected.

Turn your Bluetooth on on your smart phone and make sure it's discoverable.
Then start this proggy and let me know if it's listed as a smart phone.

Maybe some day i'll get control over smart phones and create a hands-free car kit....

Nada  :(

What do you mean exactly habran ?
You need an usb bluetooth radio addapter connected or one on board of your computer.
It should work with XP sp2 and later operating systems.
It scans for 12.8 seconds to find nearby bluetooth devices.

Press any key to continue...

Seems to work well...

I thought that it can discover my mobile phone with bluetooth on
isn't that what the car radio does? :redface:
when I enter my car and turn the key on Start it connects to my mobile 8)
my laptop has bluetooth inside

[Siekmanski]

Thank you anta40 

Hi habran,
Your smart phone is already paired with your car radio so it finds it because it has the cars address etc. saved.
For allowing the smart phone to get discovered by other bluetooth devices,
you have to select the “Allow Bluetooth Devices to Find This Device” option on your smart phone.

This is how far my proggy goes at this time.

Next step in my proggy will be to send a pin-code to confirm the connection so it will recognise the smart phone automatically the next time.

[habran]

My smart phone doesn't have that option
it has "Now discoverable as habran" option which is always on
I appreciate your work and I think that this is a brilliant idea

If you want a job done right do it yourself

[Siekmanski]

Habran, what brand and type of smart phone do you own ?

[habran]

Last iPhone5 before iPhone6 it is 64 bit

I am thinking one of the most useful software in the future would be to block hijacking of wireless tech by outside means.

[Siekmanski]

I'll have to check this, when i had an iPhone it has also troubles connecting to other bluetooth devices.  :icon_rolleyes:
It would be nice to connect to iPhones too. 

[habran]

That would be nice
I would like to see your final product
Hope you will let us see it ;)

I am thinking one of the most useful software in the future would be to block hijacking of wireless tech by outside means.

I think that would be impossible....
