Link G4 display using iPhone or Andriod phone?

Posted by Mike Cullingford at October 22. 2010

Hello, I was looking at getting a racing dash (AIM MXL) or a DisplayLink for my road car. But now i'm thinking thats a bit overkill. Does anyone know if PCLink can be used on an iPhone or an Andriod based phone? That way you could display exactly what you wanted to see, on your 4" screen on your mobile phone. If i were racing, i'd probably only want to see Oil Temp, Oil Pressure, Water temp and any warnings. It could be plugged in via the USB. I think iPhone doesn't have USB in though. Have anyone looked into this? Cheers, Mike

Hi Mike.

I have HTC droid, and I wish! Been there, thought of that I think it is a bit more complicated than it initially sounds... Out with your developers kit though... I'd pay for it!

Hello Yurgen! sorry for the old post revival. Are you able to get me the RS232 protocols so i can start working on this? Cheers, Mike 0211747427

Hi Mike... Don't be sorry for the revival, keep it going! The HTC Desire is still crying for someone to come up with a cool solution The info you need is actually all in the PCLink help file as pasted below...

3	ECU Type

ECU Status

A datastream can be requested from the ECU by sending a capital 'A'. Depending on the datastream mode selected, either a long or short datastream will be returned.

Note: Do not request data again until all bytes have been received.

All found under datastrem mode in the help file... Hope this is what you were after Mike, go hard!

How much different is this than some of the OBDII diagnostics solutions on Android etc out there already. All I suspect is needed is a clever bugger who knows how to use this data and apply it to that application.(are they not all open source) and a bluetooth module hung off the G4 Link. I wish I was clever enough to do this myself..

There is more info about this on the Vipec forum http://www.vi-pec.com/forum/viewtopic.php?f=3&t;=385 Someone has invented a 'CANopener' that will allow communication to Android or Iphones https://sites.google.com/site/canopenerdevice/ Malcolm

Re: Link G4 display using iPhone or Andriod phone?

Posted by Mike Cullingford at June 29. 2011

Hi Malcolm, that looks mostly like it's for CAN, not RS232.

I've emailed him to see what he thinks of my idea, and if his software/app can be ported over. I will look at learning how to program Andriod stuff soon, once i have my car going again.

Cheers, Mike

How difficult can it be to do a Dashcommand conversion with all the data coming from the G4 Storm? It would be great to have an application especially for an Ipad mounted in the car!!! Can I do such a thing?

Joachim

Just an update.

We have successfully connected a Bluetooth device to my Link G4 Xtreme and are receiving data on my laptop.

We just need to translate the code and then implement the bluetooth protocol's into my Samsung Galaxy S.

Hoping to have a full prototype working in the next month or so.

I will let everyone know how we are getting along!

Cheers, Mike

More Progress!

Battery Voltage (the one parameter we can adjust on the workbench) is now displaying correctly, and when we change the power supply it changes on the screen.
There is a lot of programming left to go with inputting all of the modifiers and multipliers, but it's all relatively simple.
My Programmer will is implementing lots of options from the get go, with a large amount of information parameters to be displayed at any one time (testing 12 so far).
We have the Application automatically connecting to the bluetooth when it's starting up etc, and once the application is up all you need to do is push the "GO" button to have live information streaming to your phone.
We should have a full working prototype by the end of next week, and i'll probably test it on Hans Ruiterman's car (www.ehmotors.co.nz) as my car is still in pieces!

If there is anything specifically that the community (YOU!) wants, please leave a message here or email me at mike@mpbmanagement.co.nz .

Re: Link G4 display using iPhone or Andriod phone?

I just found this little display the other day. The say it will work with Link, as well as other aftermarket ecu's. And is also OBD compliant for factory vehicles

Perhaps an option ? Video of someone using it

Thanks for everyone's support!

We are slowly getting there, the product is just being finalised and completing the connection issues we have had. The layout is still basic and some items and configurable, but basic is how i want it and will be how the program will start out. It will evolve with the User's wants, and we will try to implement as much customization as possible.

Do you have idea's for what you want to see?

As mentioned above, please do not hesitate to email me on mike@mpbmanagement.co.nz

Re: Link G4 display using iPhone or Andriod phone?

Also very interested in this.

Re: Link G4 display using iPhone or Andriod phone?

Posted by Mike Cullingford at May 25. 2012

Hello,

We are still developing this this, we have it working fine on a 7" tablet at the moment.

We MAY even be able to get this to work with USB, more development will let us know eventually.

Once the software is stable with no obvious problems we may look at doing some beta testing.

If there is anything that you guys want to see specifically, please let me know via these forums or email.

Cheers, Mike

I'm hoping there will be an iPhone version in the works, but if push comes to shove I will install can-opener. I would love to see the graphic display design you are using. Can you post a screen shot? What kind of display options will there be? If I can make a few requests, I'd like the option to have either a numeric, or simple progression line readout. Also it would be very helpful for racing if there could be an audible warning for preset conditions. Under the heat of battle there's no time to look at a tiny screen.

Best of luck on this, and please keep us posted.
