- Veepeak OBDCheck BLE+ Bluetooth 4.0 OBD2 Scanner for iOS & Android

Thanks a lot

Not for G-series on either iOS or Android. It's best to get the initial data right from the bimmercode-mouth, it is there.

Those gloves work becuase the thread in them is conductive. You can retrofit any glove to behave that way. Just buy a spool of conductive thread online and sew a little patch on the tip of the finger of the glove.

The glove alone won't work to defeat this safety system. It would still have to be on your hand.

I once saw a video of kids in Korea using a mini hot dog type sausage to work their phones with gloves on. That would work here, but you would be jamming a big hunk of meat on your steering wheel - who wants that!

With all that being said, I'm not sure how the BMW steering wheel could be capactive through the leather. That would mean you would have to touch to seams for it work and I'm not sure that's the case. Would also make the driving assist features worthless while wearing most common gloves. I'm guessing the steering wheel works on resistive touch, but have not experimented to find out.

I've brushed my finger on the steering wheel to clear the yellow hands-on warning while using ACC. It definitely acts capacitive. Who knows.

I guess the true test would be driving with gloves on.

There is no test. I told you it uses capacitive resistance HOD. Don't you believe me?

Now if someone could simulate a signal from the HOD inside the wheel, or even manipulate it, in 'theory' that would defeat the system.

Not that I don't believe you. It's just that the implementation of capactive touch for this use doesn't make sense unless the terminology is different for steering wheels as they are for touch screens. Capactive means for the steering wheel to register a touch a conductor must me placed on it (hand, finger, etc). Surely bmw would think ppl would drive their cars with gloves on making capactive touch useless.

Does this mean everyone with this car needs special gloves for the winter if they want to use the driver assist features?

Maybe they expect people that wear gloves to buy a jag

I never use them so not relevant to me, but if they didn't work, and I didn't have a heated wheel, and really needed to wear gloves then I'd buy capacitive ones.

Same principal with the HUD. Don't use polarised lenses.

What I have noticed is if you rest your bare leg against it (shorts) works fine. Jeans work well, jogging bottoms not good, so material is definitely a factor.

Guess I'm more interested in how it works through the leather wrapped steering wheel. That alone would offer enough insulation to render a typical capacitive sensor useless.

It could definitely be capacitative. Theorizing, there are two or more conductive electrode channels burrows in the wheel below the leather. That structure plus leather are the baseline dielectric and can be pre-calibrated to current temperature and humidity at car driver ready prep stage (eg during all those whirls your hear). Your hand affects the dielectric coefficient of the structure enough to detect. We did something similar at my previous company to contactless detect removal of a small bulk of plastic. With proper/careful very small signal noise control, it worked quite well and our capacitance difference was only a couple of pF — human hands are likely way higher variation.

It definitely is two-sided.

BimmerCode 3.6 for iOS is out.

Can we finally code the trunk to close with a single button push on keyfob and driverdoor button?

It would be nice to have the door handle to light up while on reverse like on F15 and add the carpet lighting too(wishful thinking).

I coded the remote trunk open. It worked as expected.

I thought opening by fob was stock and closing needs the coding 🤔

Sorry, I meant coded remote close worked as expected.

[ikheetleon]

As in, single click to close? I now have to keep pressing the button on keyfob or doorswitch to close it.

[ikheetleon]

Just coded the trunk. It can now open and close with a single button click on the driver door.
Through keyfob it works as well, but there is some sort of delay. You have to keep pressing the keyfob button until you hear a click, than releasethe button and than the trunk will close fully.

Never mind. I got it. All is good. Make sure you code everything listed including the steering wheel.

Does anyone know how to resolve this? I too coded in the auto seat hearting but cannot set either to on or off or select a temperature

read above, you have to do all 5 in order for it to work. you must have missed one.
