GPS Tether- Is it possible - G1 Android Development

Since I got my G1, I have wanted to tether the GPS to my laptop. I have Microsoft Streets and Trips, and I was wanting to stream the NMEA data over USB to the program, instead of buying a GPS receiver.
Now, I know there is a program called NMEAblue or something to that extent by a Max Kellerman, but it never worked AND I dont have bluetooth on my lappy (damn Acer... )
So, since I am not a dev (yet...) is there a program out there that can do this? Or is there a tutorial or something I can use to build this myself? (I guess now is as good a time as ever to learn to script...). Thanks in advance, and Mods, please feel free to move this as you may see fit. Thanks everyone!!!
BTW, Canon202, your ROMS are amazing!!!!! Positivley... explosive!!!!

I'm actually more interested in tethering the other way around. You can buy a 70$ bluetooth gps thats 1/4th the size of a G1, that gets fixes infinitely quicker, more accurate, and works in tree cover and around big buildings, etc.
Would be nice to tether the gps device that I have to the G1's google maps via bluetooth.

geocaching?

what is geocaching, and how can that have a positive effect on our GPS?
Geocaching
Geocaching is like a global treasure hunt where you use your GPS to find hidden containers. Inside the containers will be items people have left which you can trade for and usually a notebook to leave the record of you visiting the cache.
It has no effect on your GPS but you can download GPS software to list and locate these caches. I've thought about trying it myself.
try visiting geocaching.com
I actually went this weekend with my kaiser and bluetooth gps. i use beeline gps software. anyway from this weekends experience i found out that the phone is not really what you want to use for geocacheing; the distance to the way point jumps around a ton, i am not really sure if that has to do with the actual gps (telenav bluetooth)or the software that i am useing. eather way i was able to find one geocache out of 2.
Not too accurate then?

not sure what was the problem. the waypoint was just jumping around though.
hmm, maybe I'll give it a shot.. not sure I'll have a lot of time to do this, I've got a wife n kid and we just bought a house, so I have large honeydo list.
I haven't done too well geocaching with my Kaiser or Raphael.
I gave up using them and stick with my Garmins...
My brother does the Geocaching thing. If I remember correctly, he has to use WAAS mode (http://www8.garmin.com/aboutGPS/waas.html) on his Garmin in order to gain enough accuracy to make it worthwhile. not sure which phones support WAAS GPS, though.

[Small Review] CoPilot Live is an interesting (in a not so good way) GPS app

When it comes to no cost, data-dependent GPS solutions, Android has a great app in the form of Google Navigator.
But as someone who travels fairly frequently and can go to all sorts of places in areas I've never even heard of (and not friendly to HSDPA), that sort of solution was simply not viable. I needed a GPS app that worked offline, had routing options, and allowed me to set advanced settings for it to work as I needed. Typically, my GPS app of choice has always been Tomtom, though I also liked Navigon, and considered iGo My Way/Roadmate to be viable choices. Unfortunately, as I'm sure many are aware, the major GPS manufacturers haven't released a single GPS app for Android...with none seeming to be on the horizon.
However, while browsing the Android Market, I did come upon one solution I'm also familiar with: CoPilot Live. I remember my experience with it (on the iPhone) as being rather iffy, but it seemed to be the only good choice on Android, so I decided to give it a second chance. Well, today, after a week or two of usage, and after coming back from a journey to yet another new place in another state, I think I'm ready to give my assessment of CPL.
I don't like it.
Frequently throughout the trip, CPL had me driving around in circles. Other issues include jumpy location fixes (it would frequently indicate I'm on a road I'm not or say I passed a road I didn't). In one case, it even completely listed the name of a road on the info bar incorrectly...despite having the correct name on the actual map. Other times, it would freeze after telling me to make a turn thus making me miss the next intended turn or, best of all, tell me to make a turn only to then afterwards ask me to make a U-Turn.
The funny thing was that even when it did work fine (which was about 60% of the trip), the routing it gave was baffling. Leaving my house, I asked CPL to give me the most 'economical' routing. This is actually one of my favorite routing options CPL has -- it gives you the routing that saves gas, yet does not increase the travel time by too much. It worked well too; the routing it gave me saved over 10 miles, but did not take too much longer than the normal route.
So the routing on my way out worked fine, but the routing for the way back? Not so much. Going back, I decided to ask CPL to give me the 'quickest' routing. Now, I had also asked it to avoid tolls if possible, so logically, it should have taken me back to the 'economical' route (which had no tolls) for a part of the way before jumping me out onto a faster highway.
Instead, it seemed to have done the exact opposite: It took me through the toll, then promptly jumped me back into the 'economical' route for the rest of the way home.
Afterwards, out of curiosity, I decided to look up the turn list for 'quickest' and 'economical' towards the location I went to. The routing were almost exactly the same with only small changes. I set CPL to allow tolls and tried again; same routing as before. It seemed as if one of the best (and very well known) interstate highways used for traveling was completely left out of CPL's routing. Why is this the case? Hell if I know.
I could go on all day -- but sufficed to say, it wasn't what I had expected. It's probably unfair of me to assess it the way I did considering it's less established and (probably) less well funded than the likes of Navigon, but that's the way I feel. It's a shame really. I've been using my handheld electronics for GPS since I first discovered that my Palm TX was capable of such a thing, but at this rate, I may have to end up buying a Tomtom GPS unit.
What are the odds that your location issues are from the faulty GPS drivers and will be fixed in the forthcoming firmware update?
CoPilot's maps are the worst. They use their own data instead of using Navteq or TeleAtlas and their maps are atleast 5 years out of date in my area.
So far, I haven't found a standalone GPS app I like in Android either.
I like and use waze all the time. Doesnt work too well with the crap gps on here but on winmo it was the best app.
I used the stock samsung one that comes on the european roms that works pretty well

Almost none, I'd say.
Unlike many here, I haven't experienced any GPS issues with my Captivate. Lock-on speeds are fairly quick (it seems comparable to what I experienced on the iPhone and HTC Fuze) and the GPS fix remains in all applicable areas and not in others (bridges, forest, etc). Aside from all of that, The problem doesn't appear nearly as much with Google Navigator.

If that's the case, I wished I had tried Waze back when I had owned a WinMo phone, but the problem was that WinMo had fantastic GPS solutions, so I didn't bother using the less well known brands.
I would love an "offline" GPS App. Whatever happened to Navigon USA?

Waze is still an online solution like Google Navigation. It downloads the maps and data as you drive, so if you go out of coverage, you're stuck, unless it cached enough of the map to still work with no signal.

Thats why i like waze. Even in areas that i have no reception it still works ok. And still works ok with the crap gps on the captivate for now. So all good with me And i drive a truck so i use it alot. So far no issues that were too bad
I've been using Sygic Mobile Maps for about a month so far. It is an "off-line" Nav App.
I like it so far, was just up in Canada, on the north side of Lake Superior, with no cell/data service and it worked great. Has a pretty good POI database. Even allows you to navigate to Contacts.
Navigon for Android
Navigon actually makes an Android version now.
Not sure if they have any US maps for it yet though.

They don't. Aside from that, even if they did have it, the Android version of Navigon is not supported on the Captivate; the APK is available, but without a supported phone, registering appears to be impossible (as registering requires you to enter the last four digit of your phone number which then goes through Navigon's servers).

Thanks for the recommendation. I'll give it a try.
I also travel extensively. After trying every possible phone based GPS (iPhone, B-berry and Android), i came to the conclusion that, while some are better than the others, none of them are reliable enough to be used exclusively. So, I still carry a dedicated unit that always gets me from point A to point Z.

I can understand your sentiment.
Even on the iPhone and WinMo (both of which had great GPS apps), I still felt the need to occasionally turn to Google Maps to supplement my driving. With GM plus whatever GPS app I was using, I never had trouble navigating regardless of where I was going.
Aside from that, as I said, my primary GPS software of choice is Tomtom. I'm not so sure about the other GPS companies, but Tomtom uses the same GPS software in phones as they do in their dedicated GPS units, so there really is no benefit to using their dedicated unit as opposed to their phone versions. In fact, I would actually dare claim the phone version is better due to more functionality from the integration with your phone.
I have TomTom on my 3Gs, but the problem is not with the software, which is fine, but with the phone that periodically loses the GPS lock.
I've used TomTom for 3+ years on my WinMo phone, and it has worked perfectly.
They only problem I have wiht TomTom is they don't 'officially' support my Tilt, and getting U.S. Maps was a pain. Due to that, I've been thinking of not going back with TomTom if/when they do come out wiht SW for Android.
But, if nothing else is available, or is not any good, I ultimately may go back with them. But only if my phone is supported, (which will be the Captivate).

Huh, that's strange. I'm a former 3GS owner and I would actually rank its GPS as among the best I've ever used. Extremely fast lock-ons in virtually every condition (including the inside of my home) and I've never experienced a lost GPS lock under normal conditions, even during the one time I used it when I had to drive 200 miles out of state.
Meh, but being the owner of the Captivate, I know fully well how much the experience varies with different owners. Aside from that, the ability to field phone calls and use the GPS at the same time must be nice.

Car tuning application?

So I am a gearhead/computer nerd... I have a 1999 Trans Am and I do all my tuning on a laptop using EfiLive... Could anyone that is handy with creating applications look at the software and tell me what it would take to port it over to an Android app?
I am pretty sure my Evo has enough CPU/RAM to run the software easily and I think it would be pretty pimp to data log/change tunes from my cell phone instead of having to break out a huge ass laptop..
efilive isn't open source as far as I know, which means nobody but the original developers are going to be porting it....you're asking the wrong people

I have an 89 Trans Am GTA, however I was wondering if there was any software for live data streaming for OBD I?
There is torque in the market but it is basically like a scan gauge, not a tuner.
Dynomaster acts like a g-tech. There is an OBD-II scanner but it requires that you get an OBD-II to micro usb adapter, which I'm sure they'll sell you for a pretty penny. As far as programming, the sport compact guys use their laptops, whoever makes those programs for them might help. I've looked but have found anything, I'll just stick to my predator for now.

GPS Band-Aid

This post got lost in a locked thread, figured I would repost it.
It's a real big band-aid, but it works fine for the car and is easier than rolling the dice and getting a new phone.
I spent 20 bucks and got a tom tom bluetooth GPS receiver, combined with a free up on the market called "Bluetooth GPS Provider" and I get 1M accuracy in Maps/Nav. Since I primarily only use the GPS in the car, it's not that big of a deal to leave an accessory in there.
If you need good in car nav, and are tired of waiting for a fix, something like this is the way to go. Tested for over 400 miles of driving, never lost a fix or lost track.

Thats what Samsung should do to resolve the issue, they need to release the Galaxy S GPS Repair Kit. It comes with one of these GPS Receivers and a piece of double-sided sticky tape...EPIC!
Yeah, it's kludgy, but it works great for the car. Only thing that really sucks is that the tomtom doesn't charge from USB, means having to carry another charger too. Oh well, battery last a good long time at least.
Holy markdown batman! $149.99 marked down to $18.99? How could that thing ever be worth $150?!
That's actually kinda tempting.

That receiver is old school. It's from the pre-smartphone days when everybody rocked iPAQs. The $150 MSRP was normal back then.
Sent from my SAMSUNG-SGH-I897 using XDA App
It's still a sirf-star and better than what's working on the captivate right now!
I decided to go the same route as you. Although, I wish I did earlier because that TomTom receiver is longer available for $20 on Amazon. I ended up getting a Globalsat BT-359 for $40.95 instead.
I have to say, while not the ideal solution, it's by far the best one yet. GPS now works perfectly. Fast locks, pinpoint accuracy, no lag, and never loses its lock. It basically works how you expect a GPS to work. While it does suck that I had to spend extra money on the receiver, and that I now have the extra steps of connecting/disconnecting the receiver whenever I need to use it, it's a small price to pay to eliminate the frustration induced when using the poor excuse of a built-in GPS.
I don't know about you guys, but I always had a bit of anxiety when using the built-in GPS. Cuz at every point, I was worrying about something. At the beginning, I'd worry about how long it'd take to obtain a lock. Then once I get the lock, I worry about how accurate it will be, how long I'll keep that lock, and whether or not the GPS will lag behind. It felt like a huge weight was lifted from my shoulders when I was able to drive without having to worry about how the GPS was going to behave.
Although, this still doesn't change my attitude towards Samsung Mobile (I specify Mobile because I've had no issues with their TVs). As soon as AT&T releases a high-end Android phone that doesn't have a deal breaking issue, I'm buying it outright and selling my Captivate on craigslist.
I have a question about this thing: I use BT stereo to play music in the car. Can I use both devices at once?

Are you running Eclair or Froyo on your Captivate?
Found it here...

This is a great idea. Also, if anybody has an older android phone with working gps that they no longer use, the same outcome can be achieved with a couple simple apps. I'm using my lg eve to send the gps signal to my captivate via bluetooth and it works flawlessly.
GPS on Captivate is already fixed, it works great on latest versions of Axura/Phoenix, but for 20 bucks it's good purchase anyway
Too bad that shipping to Europe costs more than reciever itself.

I haven't tried Phoenix yet, just Axura before it died. When you say "fixed", do you mean significantly improved, or legitimately fixed. Like if you were to do a head-to-head comparison with a Captivate paired with a bluetooth GPS receiver, would you be able to tell the difference? Cuz with the receiver, it's pretty much perfect performance.

It's fully working, reliable GPS device. I don't have Bluetooth reciever, but in comparision to my dedicated Garmin navigation based on legendary SiRFstar III chipset there is no real diffrence, maybe it takes few seconds more to lock, but it's diffrence between like 5 and 10 seconds, so rather negligible in real use.

Android In-Vehicle Infotainment

So I've had a project for the last few months getting Android running as an infotainment system. Here is a demo i thought i'd share with you guys..
http://www.youtube.com/watch?v=fNcDq9S8n3I
Basic features:
Android 2.1 (looking to update to GB)
7inch touch-screen (800x480)
3G modem
GPS
Reverse camera (backup camera to see what's behind you)
USB port
would love to hear some criticism or anything regarding the device.. its not perfect, its got a few bugs and glitches.. but is sort of ready for everyday use but is missing a few components to make it 'official' android device (wifi, bluetooth etc).. but i'm just wondering if anyone is interested in something like this? Is this worth developing further on?
This thing runs on Cortex a8 omap3530 board and is based off 0xdroid build.
apologies if im in the wrong forum
Wow dude, thats really cool! I'd love one of these for my car. If you could get Honeycomb on that bad boy it'd be sweet! Just wondering, how do you plan on setting up a rear view camera? Just connect a camera at the back of the car to the tablet itself, then run the Camera app? Seems like the simplest way to me..
Haha cheers love to see the honeycomb source once its out then we'll talk although I'd imagine i'd need better hardware...
currently camera is interfaced by usb (has a usb hub) so i got a cable running under the carpet through the boot then camera is mounted on the bumper. yup camera is called by any camera calling intent.. so any app can use it.
I want to get some proximity sensors (like parking sensors) and write a proper reverse cam app to complement it. But we'll see...
Very cool!
I've been wanting to do this for a while, but I was going to use MeeGo or maybe Moblin since I don't have the programming skills (or Android knowledge for that matter) to build my own computer around Android. I dig what you got so far though.
My suggestion for the reverse camera is one of two things, because it would bug me to have to find and open the camera app every time I needed to back up.
Keep your touchscreen (what model are you using BTW?) and use a bluetooth or wi-fi relay (I know they make 'em, but they are $$$) to provide an input from +12V signal from your reverse light wire to automatically open the camera app, then close the app. Of course, you'd have to program for that.
Or
Have you considered this touch screen? Lilliput 7" touch screen with auto-reverse input. (Needs a RCA camera though)
http://store.mp3car.com/Lilliput_629GL_70NP_C_T_7_VGA_Touchscreen_w_Aut_p/MON-016-0002.htm
This is the one I plan on using since it switches automatically to the camera input whenever you are in reverse. Once you go back to any other gear, the OS input shows up again.
Just a thought to make life a little more convenient (although you already bought your parts so you may be stuck.)

Thanks a lot! It needs a lot of time and dedication but it's a real good learning curve. I had to learn a lot of things on the way.. especially c/c++ I wasn't great at but had decent skills with higher level programming.
If you are planning to work with MeeGo its a little fussy with the hardware requirements.. Correct me if i'm wrong, but I think you need an Intel Atom processor. These are a little pricey if you're after an evaluation/hackable kit! But I'd imagine it'll be easier to program as it's a lot more closey coupled with linux.

I just had a look at those relays, sounds like its something I really need! Is this how the standard backup cameras work? That was something I was confused about.. I wasn't sure how to detect if i'm on reverse.. especially with the parts I already had. I'd imagine once you implement it you just need a service running in the background to listen for the relay.
The touchscreen is a TFT resistive 4wire touch-screen. It's not something I want to keep as I really want capacitive multi-touch.. But this fits perfectly with the board and was easier to deal with

I think most factory backup cameras use two inputs and switch between them. I don't have a lot of experience with them though.

Not sure what you mean exactly. I'll try the relays because it at-least gives me a standard interface to work with (bluetooth or wifi) so there isn't any work you have to deal with on the hardware abstraction.. Although it would probably be better designed if I had some sort of voltage input coming when the vehicle on reverse (the reverse light as mentioned). But I don't really have the electrical expertise to make it happen lol.

Well essentially what I was thinking was you'd have the bluetooth relay hooked up to your reverse light wire. This should allow your computer to monitor whether or not your car was in reverse. Relays are pretty simple - one input switches on/off another, usually one of a much higher or lower voltage. So in essence, it's a switch activated by voltage. (There used to be an electromagnet inside that physically moves a piece of metal to make a connection when a voltage is applied - now it's all transistors and whatnot.)
So, if you are in reverse and your reverse lights are getting power, the bluetooth relay should sense that and signal the computer (through a serial command it seems) which in turn could tell a background service to open the camera app. Once the voltage from the reverse light wire is lost, the relay should again tell the computer that you aren't in reverse anymore and the background service would close the camera app and re-open whatever app you were in.
*I should note this is all "in theory"... I don't know exactly how those wireless relays work/communicate and I don't know Android programming at all.
Thanks for the feedback. I was thinking what about using the GPIOs on the board and attach that to the reverse light? would that be possible? and using some resistors on the way to limit the voltages so i don't fry the board.. but we just need to detect some voltage input...
Not sure, will look into it. Right now, taking a pause on the development.. Got a lot of work to take care of but I can't wait to get back into it. I really want to port this to gingerbread.

You could possibly do that, a real cheap voltage regulator would probably be better though. You could also use a cheap relay if the correct voltage is already somewhere on the car. Again, I'm not too sure how those bluetooth relays work, but it sounds like you are on the right track.
Great Job!
I was thinking of doing something similar myself.
I am looking at going with one of the tablets as it is just seems easier? I only really need internet, google maps(GPS) and wifi tethering. I would imagine you are running stereo sound from a 3.5mm? I would still have a seperate head unit to control volume and handle all the regular functions as well as inputs from a 3.5 to RCA cable.
How are you running sound off that setup? Are you running a head unit still?
The sound is running off a small amplifier. then RCA to 3.5mm.
Haven't had the chance to play around with the wifi tether as right now i don't have a wifi card.. It would make sense to have wifi tethering or just wifi reciever and use a phone to tether 3g to the system. Avoids having separate data plans.
Can we get a copy of your "AIVI Car Home" for our own DIY projects?
I don't mind releasing the source for it. Its just right now its a bit messy and quite a few things are hardcoded.

So I've had a project for the last few months getting Android running as an infotainment system. Here is a demo i thought i'd share with you guys..

Nice project. I gutted a Clarion Mind last year to do pretty much the same thing but am looking to upgrade. You said the software needs work but it's a real good start. Would you mind sharing your hardware list with us?
Nice work!
Something I was also interested in seeing is having vehicle manufacturer recommended service intervals and such available as reminders from your in car system or phone or both.

You could use 'aCar' which, if you are unfamiliar, you enter the make, model, mileage and all the pertinent service requirements. Battery every 3 years or 50,000 miles, coolant every year or 15,000 miles, oil every 6 months or 3,000 miles, etc. Then, every time you get gas you enter the current mileage as well as gallons/liters of fuel and the price. From that information you not only get your MPG but it will also trigger reminders to do the necessary maintenance at the correct intervals when they come up. You can do this for multiple cars as well. It's a very good program.
On a related note to this thread, I started my own 'carputer' project using an Archos 70 Internet Tablet and an unused articulating wall mount for TVs. It's still a work in progress as well since I don't have all the parts yet but will do everything I wanted (eventually... lol) except the rear facing camera. The video is obviously just of the media player.
I shot this late last night to show a friend. He wanted to know why someone would want a tablet/computer in their car, lol. Sorry about it being so dark.
Dude
I am keen as mustard on one of these beauties, I was considering running xp MCE but the android option would be much nicer..
Love ya work.

Please do. Would love to play with it. No matter how clean the code is it's just gonna get better...
thanks for showing it..
