Yes, running the latest build.

For MAP based vehicles its abit tricky to calculate the MPG.

Ive tried every setting, with no luck. Let em take a look and see about a config file, I have not taken much look into the file structure. it seems to work fine on my 2000 Saturn, which has got to be relatively close to the Pontiac that is featured in the one skin.

Yes, there exist space for optimization. Are you sure talking about refresh rate of 10 secs? Thats too slow. I know there exist cheap chinese ELM clones with slow rates, but not as slow as 10secs.

When hobd working there is a refresh timing in low left corner (status line). What do you see there?

in the left corner is ~3500ms when it starts and after 2-3 minutes is ~2200ms, lowest value i have seen in a 15 minutes trip was 2108ms
but i was looking at "trip time" that is why i sed 10 secs, but after this trip i have seen 5 secs refresh and 50 secs refresh at that parameter (ex: 11'59" then 12'50" then 12'55", these values i remember exactly)
another thing, can you insert a command to prevent standby?

OK, digging into the config files, here are a few mor thoughts.

Is there a way to setup a config for portrait layouts?

Can I turn off the "mph" after my speed, so it just shows a number?

Can I tell it what to sensor to pull a value from? (still working on that jeep MPG thing, as it does not show fuel level at all)

When switching from portrait to landscape on a phone, how can I get it to refresh from one to the other?

Also, would it be easier to do the font settings in the config, instead of rolling back to the theme and adjusting for "huge" and "giant"?

Thanks!
Bryan

PS.... any idea on how to run this on a Garmin Nuvi? that would be sweet!

HOBD is automatically adapted to portrait, mirroring the current layout. So you should modify the current layout, keeping in mind "mirrored" values. Thats abit junky, I know. Working on this.
Please also keep in mind that HOBD will overwrite all your changes to standard files after autoupdate. So please keep backups if you manually hack layouts/themes/etc... - or create separate files.

Can I turn off the "mph" after my speed, so it just shows a number?

Ohh.. I have finally to complete config description:
item:
size: same as in theme (small, normal, large, huge, giant)
precision: number of digits in floating numbers
units: where to draw units for the value:
below, none, aside
So your case is units="none"

Can I tell it what to sensor to pull a value from? (still working on that jeep MPG thing, as it does not show fuel level at all)

Right now you can't add dynamic PIDs without recompilation. If interested, you may pull project from github and add sensor descriptions like in
https://github.com/cail/hobd/blob/ma...en/obd2.ecuxml
But opensource part is only core (without UI), so you ultimately should give this information back to me for integration.

When switching from portrait to landscape on a phone, how can I get it to refresh from one to the other?

No way for now. Is this really needed? Not sure if .net supports orientation change indications. Will investigate.

Also, would it be easier to do the font settings in the config, instead of rolling back to the theme and adjusting for "huge" and "giant"?

Do you mean font scaling? you may use config.xml:
<dpi>80</dpi>
and ajust font sizes "globally". This way is preferred over manual theme patching.

PS.... any idea on how to run this on a Garmin Nuvi? that would be sweet!

As far as I know all Nuvi's are closed units with some proprietary OS in there (linux?). So no WinCE - no HOBD. Sorry.

Regarding decebal problems:

From logs I see strange replies:

SendCommand:0105
HandleReply: 41 05 4B
7F 01 12

Headers are switched off. That "7F 01 12" is constant for all PIDs, but sometimes it gets in front of normal reply (thats why hobd becomes crazy about this).

For unsupported PIDs it receives

----> OBD2.AirTemp
SendCommand:0146
HandleReply: 7F 01 10
7F 01 12

Does anybody knows if this ELM spec compliant???

The adapter is 25$ cheap chinese clone.

When I try to run it, it tells me that it need Frameware above 3.5.
I've got chinese double din stereo that has wince 6.0 running but its 2days I am trying to upgrade the framework but with no luck. I have downloaded more than 10 different .Net Compact framework 3.5 but when I try to install it, it says the file is not compatible with this OS....
:-(

shahabmusic,

First, have you tried running hobd-standalone build (http://hobdrive.com/download/hobd/ho...andalone.zip)?
This should run in case you have no any of .net installed at all.

The worst case is if you have .net2.0 installed in ROM. The the only way to run hobd is to correctly install .net3.5
you need "NETCFv35.wce.armv4.cab" file (part of .net35 distro) - only it could be installed on wince systems.

shahabmusic,

You may now try this build:
http://hobdrive.com/download/hobd/ho...standalone.zip

It may run on devices without .net installed at all. Hope it'll help.

thanks heaps for the help guys.
I tried it but with no luck :-( when I try to execute the hobd, windows says "The application failed to load required components. if the .net compact framework is installed on a storage card, please ensure that this card is in pace and launch the application again. if this fails, a re-installation of the .net compact framework is recommended. support info:-2147454964(8000700C)"
however it works fine on my chinese GPS that has windows CE 5 (i guess). but doesn't work on my car DVD player that manufactured by RoadRover and has winCE 6 on it.
I also tried launching the hobd by copying it to the static storage card and flash drive (those memories installed by factory) but all gave the same message.
I took a photo of the message and uploaded here in advance.

I tried millions of different .net compact frameworks (include the one you mentioned) but none of the install properly... as soon as I execute the cab file, it says it is not right installation file (or something like that)...
I could however launch MioPocket and there is a tool that I could use to find out what .net frameworks are installed, and there was version 2 (installed on rom) and version 3.5...
