    HEX-NET data update question

    So I was using the Hex-Net to try to access ATF temps and noticed that of course the 99 Eurovan doesn't support the ADV meas values.

    Then I re-read the FAQs again and found this:

    http://www.ross-tech.com/vcds-mobile/faq_7.html

    7.x Why won't VCDS-Mobile won't me show fault code text or measuring values?

    On control modules that use the latest UDS/ODX protocol, it's not possible to interpret fault codes or show any meaningful measuring value data without a 'data dictionary' file specific to the control module in question. VCDS-Mobile will get download these from the Cloud server on an as-needed basis. Once it has downloaded the data for a specific module, that data will be cached (stored on-board) and will remain available even when VCDS-Mobile does not have a connection to the Cloud server. The best way to ensure that VCDS-Mobile has the data available for the control modules in your car(s) is to do a complete Auto-Scan on any car(s) that you will be using VCDS-Mobile on, then manually check for updates
    .
    So I have been able to successfully use the HEX-NET in AP mode and infrastructure mode (or rather I was able to add and it seems connect to both my regular wifi and my mobile hotspot). I also used it as a traditional wired unit with Beta 14.2.0.

    However here is my question, how can I do the manual updates, I know where it is in the menu, but if I am hooked up to the HEX-NET through VCDS mobile it is communicating over wifi with whatever device I am using it with, NOT with the internet, right? If I connect it to VCDS BETA 14 over the cable I am checking for software updates for the PC not the HEX-NET.

    While playing around with it I did once get a "update available" notification and when I clicked to download it, it just stopped and couldn't complete it due to no internet connection.

    One other thing I was not able to achieve is the " To use it wirelessly, make sure that your PC and the HEX-NET are both connected to the same WiFi network and then select the new "NET" port on the Options screen in VCDS." (6.8 How do I get the classic Windows-based VCDS program working with the HEX-NET?), I tried both with my WIFI and my mobile hotspot (thinking maybe my wifi wasn't strong enough but the cars).

    I am sure I am missing something and I am sure I will be called stupid but hey if I don't ask I will remain stupid

    UDS controllers are a slightly different animal but for KW1281, KWP2000 or CAN modules, VCDS-Mobile will pull up the appropriate label file and will let you choose from the list of documented group numbers and fields, such as:

    Engine Load [loc 37-1]
    Sensor Voltage,Bank 3/4 Sensor 2 [loc 37-2]
    Adjustment,Bank 3/4 Sensor 2 [loc 37-3]
    Result,Delta Lambda [loc 37-4]

    That's group 037 fields 1 through 4.

    If no label file is present at all, then all 255 possible groups each with 4 fields are shown without any description, like:

    [loc 37-1]
    [loc 37-2]
    [loc 37-3]
    [loc 37-4]

    Now, if a label file IS present but there is a group that is undocumented (group 002 for example) it won't show up on the list of items you can check. But on the Advanced Measuring Values screen you can just type in the search box 002 and click Submit (not Search) and VCDS-Mobile should display the data in:

    [loc 002-1]
    [loc 002-2]
    [loc 002-3]
    [loc 002-4]

    In the case of your transmission controller, I would expect to find fluid temperature in group 005 specifically in field 1.

    I went through just about all available options under AUTO trans under AMV and none of them gave any values, that's normal?


    Also for the update I tried this:

    But I get "Update check timed out" please check your internet connection

    Your 99 Eurovan is about 10 yeas too old to have any control modules that use the UDS/ODX protocol, so that's not the problem. However, even old-school modules need a label file (which, if it exists in VCDS, should also be included in VCDS-Mobile). Can you post an Auto-Scan please, so we can see what's going on?

    As for updates: When the HEX-NET is in infrastructure mode and the network that it's on has internet access, then the HEX-NET can communicate with some device on that network (like your phone or tablet) and our server simultaneously. That means it can also get updates from the server.

    The classic VCDS running on a PC cannot update the HEX-NET. The only way to update a HEX-NET is to have it pull updates directly from our server.

    Well it works just fine in "traditional" HEX-can, and with the HEX-net used as a wired interface, so just trying to see what I can learn.

    From VCDS mobile on that car?

    Ok that's the part I never got to work, you mean using the same 192.168.0.1 address right?

    Now this would be still using the default network profile just clicking the red button to switch to infra mode? Or?

    As soon as I activate one of the wifi profiles I added I can't access the unit anymore (yeah I am sure I am missing something here)

    Yeah I figured as much but I am still puzzled by how I can have the unit communicate both with your server AND be accessible over 192....

    So when/why would I use the additional profiles for wireless. There's no other manual available yet to read aside from the FAQs correct?

    THANKS!

    Either or both. Any Auto-Scan would be a good starting point.

    No, when it's in infrastructure mode, you must specify the IP address that your router assigned to the HEX-NET. Have you watched the infrastructure video here?

    It's only I did it only in VCDS mobile yesterday and I don't know if I saved it, nor how to post it from VCDS mobile?

    OK thanks, I had everything already done just didn't check my router which would've told me the IP address thanks for the help! It is "updating" and "preparing to update" now but 0% for the past min or so...we will see...

    OK well yeah I can "find" the labels but no value is next to them
