Thread: An interesting solution to adding phone support to CarPC

AvWulf - well done.... I may look at getting a second pad for mine.... although I would leave the audio to be routed via the speakers my self because I think that is a strong selling point of the Parrots my self.

Thanks!

Well, my reasoning was: I've got a powerful amp (the stereo) in the car already -- why would I want to let the Parrot's tiny little amp take over? Also, I wanted to be able to pause the music when a call came in, and to adjust the system volume accordingly.

When the audio line is active, it also unmutes the Line-In input.

This is a very nice solution using parts that are easy to obtain. What I would like to see is a simple boxed up bluetooth module (running a HSP/HFP service) with a Serial or USB plug to it.. it could have audio inputs/outputs or just route the audio through the USB ... there are so many of those devices on the market today for OEM/ODM integration (not to say already in use), it just just amazes me that nobody has made anything like that available yet... *cough* Mitch? *cough* Mitch? *cough*...

This is a very interesting way to go and the Arduino looks like it is well within my ability to tinker with. I guess you could address the display of numbers by using the CK3100 which has a built in display. The Arduino is very well priced even in this country.

However, following on from Guino's comments, how feasible would if be to marry the Arduino up with a Parrott CK5000 developers board or something like this?
http://www.blueradios.com/evaluationkit.htm which supports a dedicated PCM voice audio channel. Downside to this one is that you are stuck with the AT command set.

I'm off on a holiday for 3 weeks now, but will be interested to see what ideas spring up when I return.

Hi Guys
well this sounds pretty cool...but has any one ELSE been successful in making this work...
I am looking up to this option but frankly speaking the layout and the discription of relay inputs/outputs is NOT at all clear....

So can some 1 help but being MORE descriptive as how to go about it....

Thanks

You could always ask.

If you are familiar with basic electronics, the system is pretty simple. But you will require knowledge on:

- How to use a soldering iron
- How to solder really tiny connectors
- Building basic circuits with relays and an Arduino
- Programming the Arduino
- Programming the software to show on-screen messages/etc

If you are not familiar with electronics and programming, this solution is going to be too complicated for you.

Good luck!

Hi Thanks for the help

well i am SURE i can do the 1st three steps... For sure
Rest two i Dont have the Expertise to write the codes or programing.....

So how do i go about the coding and programing part....

I would acutally like to know to begin with as what and how are the relays controlling... I mean after geting the Arduino board and hackng parrot for the 4 wires where do i solder the other ends of the relays....

Well, if you have no experience programming then you might simply want to install the Parrot board in the way it is intended -- mounting the little controller at the front and wiring it directly into your car's speakers.

The relays simply close contacts, in effect doing the same as pressing the red and green buttons.

Well if i have to stick to parrot the way it is intended too be... then y not just use a Blue tooth earpiece !!!!

The idea is to have every thing integrated..
Y dont you release the software that u have made...

or may be u can spare in a few mts from the hectic schd of urs to make it more detailed so that people like me in this community can benefit by ur hard work !!!!

Thanks
