    Hmm.

    I wonder how we could make this work then?

    I think the first step would be to see if my Android device can actually communicate with Robby's device. (Drivers for it would be a start I suppose)

    Bingo. Not a lot of Android tablets support the USB host profile (although that is changing). In most cases, all they can do is access a USB mass storage device (flash drive or maybe an external drive). So you'd need a device driver that either delivered the data stream directly (and your code dealt with that stream), or presented the device as a virtual serial port and then you handled it like any other serial device.

    I suspect that you should be able to see it in Android if you have a utility that shows com ports; there should be something like that available on Google play.

    Android is very iffy. Supposedly the drivers are in the software that uses the hardware. Also, yes, you would have to have a device with Android 3.0 and up, and it has to have USB Host Mode / Debugging. In the end I really thought about it and said to myself, Android does an awesome job with media. It does an awesome job with navigation. Does an awesome job with internet, etc. The Car PC though, does an awesome job with OBD2. It does a awesome job with TPMS. It has tons of ways to automate the car, and add car safety centric abilities to. So with that being said, I'll just keep the TPMS on the Car PC. I am also moving OBD2 back to the Car PC. The software on PC for OBD2 is far more superior.

    Now I asked this over on the CF forums, but I assume the code is similar? Is there a way to add a command so that when the TPMS throws a warning, it triggers a pin on the serial port? Kind of like how AMP CONTROL used to work? Basically I want to connect a small relay and if a warning is thrown, the relay is triggered and a KVM switch is switched to the input where the Car PC resides.

    Also, Enforcer, a lot of ICS tablets have Host Mode, but the manufacturer will hide the option from options. The easiest way to bring it up is to go to Google Play and download an app called USB Debug by tatibana. I received my SS808 (MK808) and the debugging was missing. That app allowed me to activate/change debugging options.

    Yes, if you have access to the source.


    Although as this is probably a unique use for I would be inclined not to add it as someone might have something else connected to the serial port. (Yes I know a etting in settings can be added to prevent that, but it might get switched on accidently)

    It might be easier to have plugin-plugin command to control a relay via the fusion brain or 4055 relay controller

    I will look into that as a USB host program is saying it needs a USB host driver.

    I'm a bit surprised that you mentioned that PC does an awesome job with OBD2. Which software are you using?

    I use Torque on Android (Galaxy Tab) and DashCommand on Windows (CarPC) and I found Torque to be a far better software in terms of customization, measurement speed and accuracy. IMHO, DashCommand has a bit more of an EyeCandy with its graphs but that's it. Its customization capabilities are skin based and relatively difficult. If a better software is available for PC, I'd like to try it.

    I dropped this idea. I am just going to have to wait till a TPMS Android App is made. I really want my project to be more Android centric. Yes I will still have a PC, but its really only for 7.1 audio processing, BT headset emulation, hotspot creation, media storage, also amp-screen-inverter control, etc. All media and car stuff I want Android. I read that Alok was making a BT version of the TPMS and that it would have an Android app. I wasnt clear on his answer on whether or not that app would work on people with the USB version.

    Your right, thats why I went back to Torque Pro.
