Is there a car charger that has the usb shorted correctly so it can recognize car dock for tasker. I have the ATT one and it doesn't cause the phone to go into dock mode.

I thought dock modes were achieved with magnetic sensors? If it is based on a pin-out adjustment then a DIY should be easy.
I ended up setting tasker to turn on BT when plugged into power source and then look for a specific pairing. When it finds my stereo it launches the car dock app. After unplugging the powers source the BT turns off and the car app closes.

Hey how did you get tasker to connect to a specific pairing? I have a similar setup for streaming music but I always have to specifically pick it, I couldn't figure out how to make tasker find it.
I did research to find out the method the captivate uses. Magnetic or pin out. From what I can find its a pin out. I can't find a wiring diagram to show the exact pin out.

A quick "where is it" response, without detailing a profile build...
you can find it under the "State" section of the profile screen
1. launch Tasker
2. select "new"
3. create a new profile name and select "OK"
4. go down the list and select "State"
5. select "Bluetooth Connected"
6. enter the device name
Hope this helps. I seriously cant believe how awesome tasker makes this phone. It does what so many crap apps on the market do, but it does it for free!

There is no magnet sensor in the phone, so you would have to see the charger go to A/C versus USB.

That has baffled me for a few days. The normal wall chargers convert A/C to D/C for charging and USB ports always run on A/C. This leads me to believe that the data pins let the phone what type of connection it has. With 8 pins on the micro USB and no video output there has to be some extras used for something. I would be willing to DIY a dock cable if there were diagrams of the pin-out and docking was possible.

Yes, I and others have posted extensively about this - searching on car chargers should find some links - but basically:
First - all charging is 5V DC. The wall charger converts 120V AC to 5V DC - the USB port is 5V DC; Car chargers convert 12V DC to 5V DC. Next measurement is Amps - wall chargers supply about 700mA - USB is 500 mA. Many car chargers are 500mA some are 1Amp (1000mA).
The wall charger automatically connects the data pins so the phone knows it is on "AC" and charges faster.
The phone will limit the Amps it draws to about 700 - if you want your car charger to charger at maximum rate - you need to get a 1A charger and you need to short the data pins at micro usb end.
I bought a dual 1 amp car charger (2 1amp uSB ports - Griffin brand i think) and I took an extra USB cable, opened the wire near the micro usb end and connect the 2 data lines (black and red are power, the other 2 are data) together so they loop back at the micro USB end.
My phone now reads "AC charging" when plugged into my car. You will never get this on a PC USB port as it does not put out enough power.
But if I understand correctly it should know the difference between home dock and car dock.

Based on what Alphadog just posted the phone could determine if it is on a USB (pc/data) connection or an A/C connection. The outcome could vary depending on the specifics of the device being used to charge the phone but it comes down to the pin-out.
That being said, I was looking at some of the Tasker settings that could be used in this scenario. I was thinking for those who do not have BT that other triggers could be used. A good trigger for docking could use combos such as "power" and "orientation" or "power" and "location".
A second thought had me wondering about the compass. I have not looked into this but I don't see why you couldn't utilize the compass as a sort of magnetic sensor. If for example we told tasker to look for a specific scenario such as:
1. Receiving ac/usb power
2. Phone in Left Horizontal orientation
3. "Compass sensor north" pulling towards orientated left
Tasker would then launch Desk Dock.
....I know, Tasker does not have settings for current compass sensor direction. but could a specifically written app do this?
I currently use orientation and power for mine.

I have the car charger you can buy at att. It has a usb port I'll have to try it with the usb cable that came with the phone. If that works then I could have saved alot of money buy just buying a generic plug with usb
dont bother with tasker there is an app for that
use DockCarSwitches to turn bluetooth on when docked in car(car charger)
use Bluetooth Application Launcher to launch your application(Car Doc application for example) when a particular bluetooth device is paired
This Samsung car dock both charges your phone and activates the car home app.

I think you misunderstand the point of Tasker.
To get USB/AC under Settings / About Phone / Status from a USB Car Plug, you need 2 things: 1) A Car Plug with enough Amps (I use a model that has up to 2100mA in a single USB socket. Even runs & charges Android Tablets at same time) 2) a correctly wired USB to microUSB cable. (same place that sells the high power USB plug has this cable)
When I use these two together with my Captivate, it charges very quickly.
By the way, both Gigabit and Asrock motherboards are shipping motherboards with Always on, high power, USB ports.

That's incorrect. Unless, the dock the OP uses requires it somehow. It's much easier to short the Data connectors on the larger end of a standard USB to Micro USB cable to trigger the phone for AC Charging. It takes less than 2 minutes and requires no wire splicing. Linky

I have the official Samsung desktop dock for the GN with pogo pins for charging. I cut out a notch in the left side of the dock so that I could access the USB port on the phone when it's docked. I'd hoped I could then attach a USB OTG cable and mount a flash drive while the phone charged via the pogo pins.
Unfortunately, the two functions seem to be mutually exclusive. If the phone is in the dock and charging and I attach the cable and flash drive, they are not recognized by the phone. Or, if I attach the cable and flash drive first and mount the flash drive before placing the phone in the dock, charging doesn't initiate when I put the phone in the dock.
Does anyone know if there is some way via software or hardware to force pogo pin charging while a flash drive is attached and mounted via a USB OTG cable?
I will try tomorrow on my self built car pogo charger and usb otg. I have aokp with the fast charge override feature.

Sounds great! Thanks much. If it works, it'll tempt me to go to AOKP myself.
Any luck on this?
I too want to use OTG functionality while charging phone in the official car dock.
USB OTG + charging
I'm actually trying to get the same get something like this going on a galaxy s2 (the I9100g with the omap processor) or a GN, My goal is to get usb host and charging going through the same cable. By making some changes in the kernel i've got the phone to think its in charging mode while in host mode, but if you check the battery status, it's still draining even though it says "charging" and I've got the a usb "Y" cable connected to a 5v 2amp power source.
I think cyanogenmod (there was a post on this here and a standalone app that eventually rolled into the latest cm7 nightly) has this working on a BN nook color (also TI-OMAP Processor), but I have not been able to verify this.
Does anybody have host+charing working on any device with an OMAP processor?
Sorry for the delay, I had an emergency work trip offshore on an oil rig. I can try it out tonight.
Results. Charging OTG killed pogo charging. I tried mounting in pogo charger with OTG already attached mounted with a basic thumb drive. Charging never started. I tried charging with pogo first, then plugging in OTG, charging stopped. I checked to make sure it was actually discharging by waiting for a few percent decrease.
Sorry, I was hoping it would work too.

Thanks for giving it a try. It would be interesting to know if this behavior is built into the hardware or could be modified via software/in the kernel. It's consistent with what happens when using a powered USB hub.
Other than a software mod, I'd sure like to see someone start making and selling an Accessory Charger Adapter as described in Chapter 6 of the USB Battery Charging Specification document from 2010. It's the exact thing needed to use USB OTG and charge at the same time.
Anyone knows if its possible to charge via USB, with a device connected?
I connect an adapter microUSB to USB OTG, than connect USB OTG in a USB HUB and than i connect a device in one USB and force in another, is it possible or not??
It may work, since connecting to the pc works.
I've got a Note 10.1 2014 mounted in the dash of my truck to replace the radio and am on a mission to figure out how to get USB OTG to work with charging. I've read an ocean of threads regarding hacking MHL adapters, but there is not any information specific to the Note 10.1 2014.
Right now I've got a relay system in the dash that switches between a OTG cable and a charge cable depending if the ignition is on or off. This works for my basic purposes, but if I use GPS navigation and wifi tethering, I run the battery pretty low after only 3-4 hours. When I turn off the truck it begins charging, but that wont work for a road trip.
I've tried the Samsung smart dock (without reading that it wouldn't work), and of course, it doesn't work, although it would be the perfect solution.
My idea is that there would be some way to use the 11 pin MHL connector on the device to get what I'm after. Looking at the pinout, it seems that there are some USB host pins within the 6 additional MHL pins, but I do not know of anyone who has tapped into them and had OTG working.
Is anyone else trying to get this to work on a Note 10.1 2014? I'm happy to hack up and solder anything and everything imaginable to give it a try, but I'd like to collaborate about it and see if we as a group can get this working.
Im about ready to rip apart my smartdock and see exactly why it wont work with this tablet.... have no idea why it qont recognise the tablet...

Meanwhile, is there a possibility for that knock-out?
High current charging has an impact on the signal lines. So USB 2.0 current is limited to 500mA, or probably the 900mA from USB3, if the port can provide it. On a standard USB2 port the Note remains self-powered. And even with 900mA it will slowly discharge while in use, despite the battery charging at max current. On a 2A charger, the operating power bypasses the battery, which is much more healthy for it.
Thank you for your reply. Unfortunately I asked imprecise. What I liked to ask is, if there is meanwhile a possibility to charge the tablet while using the usb connection e.g. with an external hard disk?
Almost certainly not. Samsung could have provided a charger jack, or even support wireless charging. But it was not meant to be.
I just tried one of the charge and 2 female usb adapters off ebay and it didnt charge. It detected the usb connectors connection, but wouldnt charge.
$5 lost...
Did you used the wall plug? Because the tab needs 2A for charging...

Why not take away the USB requirement? I assume you want this to allow external storage, in this case get some sort of NAS that can be 12V powered and install that in your truck then allow the Note to connect to this via Wifi, then the USB port can be dedicated entirely for charging only.
Plus you have the benefit that when at home you can transfer file to your NAS without needing to leave you PC.

Are you using the LTE/3G for internet access? if not then setting up a wireless network in your truck might work. I use a HooToo TM001 (also have the TM002) to do this set up. The hub has a 6000mah battery that when the USB drive is not installed can charge a device.
i know it's been a while since OP posted, but i've been using a wireless HD so i can use external storage and maintain a charge. if you get the seagate wireless plus, you'll be able to charge and stream at the same time as long as you use a usb3.0 cable to charge from (it's included). using a 2.0 cable will turn off wifi.
it's quite a bit more than OTG, but it does allow you to have tons of storage available while still having a charging option.
I use a nexus 7 in the dash of my car (sure do wish I had space for the note 10.1 in there though!) With the nexus 7 I bought a y-cable that allows me to charge AND use otg functions. However, a specific kernel was needed im pretty sure. I set it all up a while back so I cant remember specifically sorry. Its all nexus 7 forums here though.

yeah mate, i'll have a look for you. the nexus 7 is out of the car now cus im trying to make a custom facia to fit the samsung note 10.1 in there. so I'll have to charge it up and have a look which kernel it was running. but im pretty sure it was just the default one that came with the AutoDroid rom in the nexus 7 forums.
if you don't hear back from me just pm me, I'm forgetful as hell and its coming into exam time....so yeah
I have a dual usb car lighter adapter that I use for charging all my devices while I'm in the car. For whatever reason my Tab will not charge when I plug it in. I also have a usb port on my stereo that I tried but it just went into mass storage mode with no way to get it to switch to charge only. Is there any way to fix this?

if im not mistaken, the tab needs at least a 2 amp power supply to charge. most usb chargers and usb ports only put out 1 amp or less.
Hi.
I bought an android head unit for the car but the built in Wifi is 99% useless. It does not pick up any routers in my area including mine which is 10ft away! If I use my phone as a hotspot, the phone has to be within 30cm of the head unit to pick it up, and the download speed is terrible. I have a spare USB socket on the radio so can I connect a wireless USB adapter to it and if so, how do I install the driver?
Many thanks in advance.
nope never seen this but check the internal wireless antenna.... open the radio and make sure its connected.... sometimes Chinese forget stuff
