Hacking into Zoe's CANbus

[jmeijer]

It looks to me the left two windows are fine. The right ones should build up a graph, you need to keep it running for a few minutes. It looks like the top right screen it has received some data.

Anyway, can you please report the issue here?

https://github.com/fesch/CanZE/issues

That way the developer who made this particular screen can ask detailed questions and you will be automatically notified if there are changes made. Thank you!

Thank you. You are right, the right ones build up a graph. The screenshot had been taken while the mobile phone was not connected.
My problem is that I can't enlarge the diagrams/graphs to read it clearlier. Sometimes it works, sometimes it doesn't.

The tapping problem is found and fixed. That fix will be incorporated in the next release. https://github.com/fesch/CanZE/issues/301

Please report crashed if they happen on github with as much detail as possible, Thanks!

Motorola Moto G2 with Android 5.0.2 also works fine with CanZE using MaxiScan Dongle.

Hi to all the great engineers of this great project.

I am working on something similar, on a fix installed Display. But we have not all the Information about the CAN Matrix, so we stuck a little bit.
Is it possible to share the information so that we get a new boost in our project?

PS: I tested your Software on a SONY XPERIA, Modellnummer E2105, Prozessor MT6582, Android 4.4.4 and it works great on this phone. Only the linking to the bluetooth Device is not able to deal with the R-Link. The phone should be deleted from the R-Link system and the Device should not be cold....

Sure. The entire project is Open Source. https://github.com/fesch/CanZE

The field definitions can be found in Class "Fields".

Of course we wouldn't mind acknowledgement or maybe even software development contribution, but it's free (as in: free beer)

of course you get all our SW-source-code, but it is C-code, I am not familiar with Java and so. I have some Ideas about a new display of the cell-Voltage or to calculate some parameters like driving resistant and air resistant out of car running out from high speed.
Of course the source code will be yours!

Awesome project! Is there some other, similar project available as Open Source, too, for normal cars?

I'm asking because I've already tried to get an Arduino with HC-05 BT shield to connect with my older OBD2-BT adapter but without much success (setting up a reliable blue tooth connection was the problem).

[jmeijer]

What I would do, is diagnose if the problem is between the HC-05 and the Arduino (i.e. using SoftwareSerial). To do that, wire your HC-05 to your PC, like in my video. It was absolutely rock solid reliable in my case. https://www.youtube.com/watch?v=TQRatlPNUmw

I don't really understand though what you meant. For an ICE car, things like Torque (light) work pretty well, depending on your goals of course. If you want to use this setup for the Zoe, I strongly advice you not to go the dongle + BT + Arduino AVR route, but use a tranceiver + Arduino Due. Cost is the same, much more reliable and blazing fast. https://www.youtube.com/watch?v=6Ei03NHvTKA . Timing and buffer issues are pretty hellish with the dongles.
