OTG GPS & Charging on 5th gen? - Fire Q&A, Help & Troubleshooting

I see a thread about OTG charging not being possible due to the Amazon kernel that is a few months old, has anything developed as far as this? I'm planning to install one into my cars dash and it would be great if I could also add a GPS module to it but obviously I need charging capability since it will be inside the dash and always plugged in.

Nope. You get one or the other. That's unlikely to change as such use does not benefit Amazon (no clicks). You might consider a Bluetooth receiver which would leave the USB port available for charging.

Fantastic I never knew bluetooth gps modules were a thing! Do you personally use one? I'm not too keen on modern android especially when it comes to separate devices like this, will I be able to use it with any maps app and be able to set the default gps device or will it only work with certain apps designed specifically to use one?

Search Amazon "GPS receiver bluetooth". Pricier than usb receivers. I do not use one; prefer devices with integrated chip. However, I have tried a USB receiver on this device to verify it works. No personal experience with BT receivers. Another poster mentioned an app that would permit reception of GPS data from another device such as a phone. Good luck.

Nook Color "standalone" GPS... there's gotta be a way...

I've seen these simple USB GPS receiver antennas that hook to a laptop for GPS duties so naturally I'm thinking why can't this be done for the nook. Ideally we would have a dual/split port so power could still be supplied at the same time.
I'd rather have this config since I don't like the idea of tethering to a GPS capable cell for privacy reasons and it ties up the cell too.
Why couldn't this be possible? Is it just a matter of the Nook recognizing the GPS antenna and being able to get a software package to recognize it?
Any ideas?
With CM7, and a bluetooth GPS reciever, this is no problem. We will never be able to build a GPS into the device, but we can get close enough...
Yes, my intention would be to leave the GPS antenna in the vehicle and just hook up when I get in. Along with MP3 duties of course. It shouldn't be hard to find or make a USB gender changer with dual connections.

Im not following, sorry.
I just ordered a "kit" for my NC actually - a car window mount, and a stand-alone BT GPS. I plan on attaching the the GPS to the window mount via velcro, and leave it in the car. You don't need USB at all (nor would it work, since our nook does not currently support usb host). Just get a BT module, and leave it in the car; connect it to the nook when you need it. done.
Ok I see what your saying. But Im not familiar with Bluetooth recievers. Are we talking about just a regular GPS with a screen and all? Then why hook it up to the nook? Or are we talking about a little box that just sits on the dash or tucked away somewhere?

Ah, let me fill ya in then.
What i am talking about are standalone recievers - nothing more than a GPS and BT transmitter. No screen, no frills. Most have batteries that will last for weeks, and are small enough to store anywhere in the car when not in use. YOu can see a good selection here:
http://www.amazon.com/s/ref=nb_sb_n...eiver&keywords=bluetooth+gps+receiver&ie=UTF8
Hope that may give you some new ideas.
Aaaahhhh..... yes I see now. So it would be just a matter of finding one thats compatible with our NC's and the software for it... cool. Anyway to know which one works the best for the Nook?

Now, i guess i cannot guarantee, but in theory, ANY BT gps should work with our system, since all GPS's transmit in the same standard. All you should need for software on the nook will be:
https://market.android.com/details?id=de.mobilej.btgps&feature=search_result
or
https://market.android.com/details?id=googoo.android.btgps&feature=related_apps
Assuming my GPS arrives sometime soon, i will be able to give ya some first hand advice.
You will still need a data connection if you intend to use Google Maps for your GPS software.
If you want to use it without a data connection, you will need something like this:
https://market.android.com/details?id=com.alk.copilot.market.usa&feature=search_result
"maps stored on your phone, not downloaded"
Also note, Bluetooth range is very limited on the NC. My BT GPS has to be within 2 feet of the NC to connect.
That is true, a stand alone program is the best, but google will cache the maps if you pre-plan the route.
As for distance - with a car mounted GPS< you really don't need to worry about that - the GPS should be by the windshield anyway, so keeping it close to the nook isn't an issue..
What about this Google "Navigation" program that is on the nook? (the blue arrow)

You'd still need a data connection. The best probable solution would be to tether to a smartphone that has GPS - so the Nook has a data connection for the Google Maps and Navigation, and GPS data from the phone's GPS.
I was interested in the same thing and went so far as to successfully pair my Garmin bluetooth gps unit with my CM7 nook, but I was not able to actually read any gps data. (This unit was successfully used with a linux laptop and car computer, so it works in linux.)
While looking for a way (hack or software) to read the gps data I found the TetherGPS app, which meets my needs- and yes, I have received phone calls and browsed the web on the phone while using nav on the nook without problems.
The biggest issue I have found in the past and NOW is that I do not think much of the other gps nav options available on Android (or linux!) and caching a limited tileset with Google maps is not enough for my needs. My routes often change.
I do have another bluetooth puck around, if I can find it... I will test to see if that one is easier for the Nook to read data from.

It will pair, but you need to use an intermediary program to access the GPS, like this one:
https://market.android.com/details?id=googoo.android.btgps&feature=related_apps
or this one:
https://market.android.com/details?id=de.mobilej.btgps&feature=search_result
or this:
https://market.android.com/details?...oid.addon.bluetooth.GPS&feature=search_result
I had trouble with some GPS apps.
I was able to use the GPS and data access on my Motorola Cliq to have GPS voice guided navigation.
http://forum.xda-developers.com/showthread.php?p=12076390
That is how I accomplished it.
If you have a hardware GPS, then you only need the 1 app, which is even easier, but I still recommend wifitether or barnicle for data access (you can download the maps for offline use if you plan ahead.)

I actually tried those apps to no avail, which is why I started looking for the other puck (not as accurate but easier to connect) and alternative solutions.
I actually had looked at all of the other (non- Google) nav apps for Android before to use with a now unused Droid (original) but found them all to be ... less than desirable for various reasons.
Note that I am NOT trying to discourage this project- it is possible, I am certain, but much like linux navigation software... lacking a certain "polish" if not functionality.

A few Nook HD questions

Hi, I'm thinking of getting a 7" tablet to install in my car, I'm not looking for anything super high spec as I'm literally just going to use it for mapping and playing music. That being said, the nook HD looks like a really good spec for the price..
I've just got a few questions
It doesn't have GPS, but I assume it will work using a bluetooth GPS once I've installed CM10?
I understand it uses a proprietary usb cable, how far does it stick out? Does anyone have a picture of it? This may be me only problem mounting it in dash as I wont be able to find a right angled one!
Yes, you can use a Bluetooth GPS puck. I haven't gotten Google Maps to work with it yet but I have gotten other programs to see it. A 3rd party GPS program should work with it. I'm still planning on testing that theory but to much family stuff has been going on right now to actually do it.
With the connector and the way the cable is wrapped right next to it it sticks out about an inch (just a little under that) from the bottom of the device. I'm pretty sure that to much pressure on that part of the cable will make is useless so you would have to make allowances for it. Also, it needs more power than a normal micro usb cable to actually make it charge. The AC adapter puts out 1 volt at 2 amps.
Got Sygic working today. Had to use this program to get it working though. https://play.google.com/store/apps/...?t=W251bGwsMSwyLDYsImRlLm1vYmlsZWouYnRncHMiXQ..
Other then that seems to work quite well. I should mention that I am on CM10.1.
I got Google maps to work fine with my phone using Bluetooth for gps and Wi-Fi for data.
Have to see up maps to accept debug data and use bluetooth gps programs on both devices

Possibility Of Getting GPS Working?

Possibility of getting GPS working?
What are the chances of getting GPS working on the Fire? The info thread has a post saying the chip in it is a MediaTek MT8127 and links to the spec page which says it has GPS on the chip, as well as an FM receiver. Curious if it requires dedicated antenna connections that aren't there on the Fire, or if it's ready to go hardware-wise and just requires something on the software side? Would be pretty awesome to get it working and use these as a dedicated car tablet, especially now that cm12.1 is booting on it thanks to ggow, and the upcoming Black Friday $35 price.
GPS would require it's own antenna (plus a couple of supporting components) since it's a different frequency than wifi/bluetooth. So even if the chip includes GPS we can't use it.
Tho in your scenario of a dedicated car tablet you should be able to use a cheap usb GPS dongle. The fire has USB host.

Which OBD2 adapter?

I have old OBD2 v1.5 adapter. Chinese, big one. Which pairs with HU and works well.
I wish to buy new one, that call 'mini'. I know I have to look for v1.5 (as 2.1 is a crap) and with PIC18F25K80 chip.
But I read that even much of these new mini are PIC based, that have some strange Mac address like AA:BB:CC:11:22:33.
Anyone has experience with such adapters? Do they pair and work with Torque on our HUs?
If anyone is using such an 'mini' adapter, please post link to eBay/AliExpress where you purchased it. Will be very grateful (and it may help other people here, too, as many have issues pairing/using crap adapters).
I personally bought https://www.ebay.com/itm/Auto-16-Pi...le-Diagnostic-Adapter-For-elm327/152700822059 and https://www.ebay.com/itm/2017-ELM32...uto-Car-Scanner-Scan-Tool-Cable-/112070132071 so I connected it over USB and only thing I've made is HW MOD to get ACC+ instead BAT+ from OBD2 so that it is powered only when Key is turned on.
Resolved pairing issue with no pairing and all works along with BT and WiFi free for other devices.

Thank you for sharing. I was not considering USB option, but it sounds interesting.
I see you both the 'big' one (same as my old one). And they really work very good.
But I would like to buy some of 'mini' models as my OBD2 port is in such place (under steering wheel and just above brake pedal) that big one is too big and my feet is hitting it while driving. Here is obe model I consider

There are 2 models of these (not colours): old design with 2 PCB boards, and new one with just 1 board. I wonder if anyone has any of these?

:silly: I do not see the problem there as if you checked both links from my post you would see that I use extension cable that do not have issue with connector position. Mine is located right above gas pedal so I could not drive car normally with any OBD Adapter unless I used extension cable.

PIC is programmed micro controller and not actual ELM327 see https://www.elmelectronics.com/products/ics/obd/ and v1.5 nor v2.1 exist officially as they are clones and you should use https://play.google.com/store/apps/details?id=com.applagapp.elm327identifier to test actual model and support.
Re which one: I ordered 6 different models and kept two that worked flawlessly with my car 1 was broken (got refund) and resold other 3 to get my money back.

It is fairly simple MOD:
1. Soldered positive wire of lighter connector that have power only when Ignition is turned on.
2. Bought FLAT cable that I can easily cut the wires like in picture s-l1600.jpg
3. Cut Wire on pin 16 BAT power see ODBII%20Master%20Pinout.jpg
4. Connected wire that goes to OBDII to Positive wire I prepared in step 1
5. Connected OBDII to connector from FLAT CABLE
6. Connected USB to HU SINGLE USB CABLE
7. Tested if all works with Toque
8. Used cable ties to secure all cabling behind dashboard
and now I enjoy the all the diags on HU

Thanks for this info, very helpful, just got Android 8 Eonon 2170, and I've been struggling to pair OBD, Kiwi 3 doesn't show (BLE not supported? Don't know), Tomtom unit won't pair, no name unit seems to work, but, I've thought, why not USB, started searching for USB Android supported, luckily came across your post.
To change BATT to ACC, is that just so it's ' done properly'?
Surely battery drain would be miniscule, or not? I guess makes sense to have it not powered all the time.
Going by your posts, so, some of these units didn't work properly,ECU side or Android side? Thanks again, A
I just looked into factory settings, there is a CANBUS section, currently set to NONE, should that that altered to car maker's CANBUS ?

It is not the problem that it drains a ot but all small drains can pile up so eventually you have a problem. I have park mode security enabled on my dashcam system so it drains some, OBDII can drain a littl, but it is known that in some cases keeps ECU awake that can drain a lot due teh number of sensors it keeps awake also

All was ECU side due the different pinouts see my pics, I have seen in the past several USB -> COM chips that are not supported on Android due the OEM build and specific drivers like some factory that are not recognized on laptop till you install their licensed software (Usually JUNGO Based Drivers).

Only if you got specific cables with canbus decoder (black little box). even then USB OBDII is used to diagnostic and clear codes. I use Toque 1.83 and it works on one unit that v1.52 didn't worked with. Usually ELM v1.5 works better than v2.1
thanks! I have now got USB OBD unit 1.5 (still need splitter/extender), tried yesterday with Torque as well as with Palmer's DashCommand:
it kinda worked - during first trip, 45min, Torque app crashed twice or more, worked after restart, on return trip, DashCommand also choked once or twice, thenm I relaized, as fuel tank level is not reported, unless I run app 100% of the time, fuel consumption won't be correct - and, realsiticall, I need TomTom on the screen more than gauges....
I see there are OBD spliters that 'allow' two or three OBD devices plugged in, wouldn't you know, is it OK to split/use multiple OBDs ?
like, I have TomTom 'Curfer' OBD data logger - just logs 'quality of driving", thoiught to get splitter to log data, AND, if so desire, call gauges on screen ?
thanks for explaing CANBUS!
do you use TPMS tyre pressure units, if so, which ones ? my radio has an app to read such, wonder if it's worth it ?
I have connected my USB OBD. Torque not recognised device. How to check that Scanner is properly installed on android system?
OBD scanner is generic just like this:
https://www.amazon.co.uk/ELM327-USB-Interface-Diagnostic-Scanner/dp/B00IWLLX1Y
BTW I have MTCE with android 8.0 with KLD MCU.
Torque lite ain't work with android/usb, only in bluetooth mode.
I have torque pro so there is no problem there.
Any way problem solved. Bought Bluetooth version.

Android Auto Wireless Adapter for Standard Head Units

I mean, this can't be that hard right? We know USB data can be transferred over WIFI. Thats probably what is behind the tech of the new wireless feature in the head units. The car has wifi, the head unit knows it and uses it with your phones WIFI and blue tooth in tandem.
I can't really rely on GM to update their Android Auto head unit even though my car has WIFI and it would be easy. They just wont do it. So, I was laying in bed brainstorming. There has to be some small dongle out there that plugs into the cars USB port and uses your phones wifi to connect to it and create a USB connection as if it was plugged in directly. Then the head unit wouldn't need the wireless feature.
Or, you plug the dongle in, and the the Android Auto head unit knows what it is, (just like if you plug an android phone in with Android Auto) and the dongle creates a wifi connection with your phone. Then the head unit wouldn't need the wireless feature baked in. This can't be that hard to come up with can it?
I think it may be possible using a few items
1.)Modified OpenAuto (already supports wifi) that redirects or clones AA data to usb
2.) Raspberry pi zero w
3.) this Zero usb adapter
I'd be willing to work on it, but seems like a big task to undertake to modify OpenAuto.

Also would want to donate. There is a market for this if stable and effective. Let us know.
This seems like it is possible if we get a device that works somewhat similar to how Nintendo used to allow wireless connections for their older consoles. They would connect a USB to a PC and bridge the wireless connection to the USB and LAN on the machine. We would need a USB dongle that can take the wireless commands and send them as if the phone was a native host connected via USB.
It'd be interesting to see if it could be done with a Pi Zero W, as the two technologies are *technically* compatible, indeed, when you connect to the Desktop Head Unit, it transmits TCP data over USB.
Unfortunately I don't have a Pi0W to give this a shot with
I'd be all about this.

Hi Guys,
what about this? Nothing? I've already checked the other solution, but I would like it much better if could be done it with RPi, "natively" redirect the data between wifi and usb. So the phone can connect normally directly by Android Auto app using wifi without any other 3rd app.
Could be possible? Of course I also would donate this project!!!

Yeah, apparently a Chinese company made this kind of usb dongle but only for carplay. They converted the factory head unit with carplay from wired to wireless.
I did asked if this will work for AA, but reply is no.
