Use external BT GPS receiver? - Nexus One General

Apparently my cars GPS radio is accessible via BT. Is there a way to get my N1 to use that rather than the internal GPS radio? Reports from users of other phone OSs seems to indicate it locks faster and holds signal better so I'd like to give it a try.

accessing internet via satelite

I am curious to know as I use my pda for the main purpuse of road navigation but would like to know if also I can access the internet through the gps receiver.
Sorry but that cannot be done, the gps receiver is a receiver only unless its bluetooth in which case it receives the gps signals and transmits them over bluetooth to the phone/pda, it has no capability of satellite communication for internet.
if the gps satelite had access to the internet and would send data and the gsp module had support for recieving data i guess it could be don
but since gps was invented by the us army and they still use it i doubt they would add too much internet support in that system
also it would be a bad thing for all people who were using gps when the whole system would crawl to a halt when little timmy were downloading powerranger mpg's
It couldn't work, how would the satellite receive the page request? To do this, the GPS module would have to be a transceiver...which it isn't.
I guess for this to be possible, you need a satellite chip like in a sat. phone....I wonder if anyone will produce one to go in a CF slot anytime soon? Would be pretty cool!

A GPS Receiver mainly receives clocking signals from different sattellites and calculates your position based on the timedrift between the different clock feeds.
These clockfeeds are actually broadcasted on a singal transponder and single channel for each sattellite... in other words, everyone receives the same stream... so no luck there
Regardless of that fact, a GPS receiver is usually pretty dump and doesnt have the brain to maintain Layer 2 (let alone 3) cohesion for a data stream.

GPS only works when phone or bluetooth ON ?

I believe that this also affects other HTC models, but I'm puzzled by it:
If I go to the communications menu and switch off the phone receiver, the GPS also seems to stop receiving. Enabling Bluetooth seems to bring it back to life, but enabling WiFi doesn't.
I don't always want to have the phone receiver working when I'm travelling using GPS, so it's rather annoying.
Does anyone know the reason why this happens ?
Are there perhaps some common parts of the Qualcomm chip that are shared by the GPS and phone and/or bluetooth ?

Bluetooth "full screen" pop up - avoidable?

Hi,
I am using GPS mod Driver in the newest version:
http://forum.xda-developers.com/showthread.php?t=571266
The great thing is that gps mod driver - beside it´s other functions - is scanning now different ports to find gps receiver sources, which is quite usefull if using the HD2 in a rental car and lay down the HD2 between the chairs (bad internal gps reception) and put a BT gps receiver under the wind chill window for good reception (a BT gps receiver needs quite less space than a HD2 fixture for the wind chill).
While on power gps mod driver is scanning apporx all 30s the specified ports to find a better gps source (on battery not to save battery obviously).
Now the problem:
If I am on "power" but have no BT gps receiver attached (using the internal gps source) I am getting now approx all 30s a full screen pop up which is asking me to switch ON BT, or if BT is ON (because I want to use my BT head set for example) to select my paired gps receiver.
This is not realy convinient because as said it is a full screen pop up and is hiding therefore the entire navigation software AND is requesting a confirmation press to go away (and this every 30s ...).
This behaviour is not only related to the HD2 and it looks like it depends on the BT stack which is used on the smartphone. Ohter HTC smart phones with a different BT stack are not showing this full screen pop up meassage.
Question:
Does anybody have an idea to influence this behaviour on the HD2 by any reg setting or configuration?
To put BT notice in a "silent" mode?
Best regards,
dingolino

[Q] BT Serial Port SPP (rfcomm) maybe someday?

I can't post this in development because I an still a nobody ...
Would it be possible to add in rfcomm for Bluetooth SPP serial port? The Nook would make a great tablet for telescope mount control over BT. You can't do it with the iPad due to the security around the BT stacks. It would also allow NEMA GPS modules to be read for different applications.
I'm running CM7 7.0.2 and this isn't yet available.
Just a dream?
Not sure if this is what you're talking about, but you can send the GPS data to the Nook form a GPS device like a Cell phone or GPS receiver. I use a stand alone GPS receiver and sometimes my Droid cell phone to send my location to the Nook to use CoPilot and Google Maps on the Nook. That's at least half of what you're talking about right?

Hmm, you got me pondering...
I got out my trusty Garmin GPS 10 and I can pair but it's not connected. That could be for a couple of reasons (the Nook only connects on demand maybe.) But if what you are saying is correct, maybe it does support SPP since it uses a comm port for the GPS.
But, when I connected from my notebook and checked the services, SPP wasn't one of them (just OPEX and AD2P.) I will keep playing but I half expect that part of the SPP stack requirements are missing.
On the plus side, if the GPS will work too, that is a second plus since it's nice to be able to ask the GPS for the specific time and location during the telescope setup (it matters.)
I'll look for an app in the Market that might read an external GPS devices and show the location. I notice most apps are for reading the phone GPS (which we don't have.)
Thanks!
Android does not support SPP, but there are multiple apps in the market which do, Bluetooth GPS Provider is the one which I prefer as it works very well and just works no matter what.
Thanks folks,
I fired up the Garmin GPS 10 and it works using Bluetooth GPS. That means an application can add in the SPP. That is perfect and gives us hope!
I really appreciate the responses!

Yes, apps can directly talk with a Blutooth GPS. There are a handful which do this, or again, Bluetooth GPS Provider will provide the BT GPS to every app that asks for GPS.
This isn't only about GPS. GPS is just one aspect. I want to communicate with any serial device over BT. My understanding from reading it that rfcomm and the applications can supply that function.
What I did notice last night is that even without an application that supplies rfcomm, the Nook would still discover the devices unlike the iPad. I could pair to pretty much anything I wanted but it wouldn't connect. That's normal from my perspective.
At least I know it can be made to work.

Well, the XOOM does at least. Not sure whether it was Motorola's or Google's doing though. I use a Bluetooth to Serial adapter from Roving Networks quite successfully with it. I'm unaware of any other devices that do it.
I agree that native Android doesn't support SPP but the rfcomm library does and if it's linked into the application, SPP works.
Now if I can only find a way to use VNC to control my PPC from the Nook without going through a remote server (maybe via adhoc or BT ...)
Any device at API level 5 (2.0) or above may support BluetoothSocket, RFCOMM and therefore SPP unless the OEM did something to screw it up.

using as an externl gps ?

Hello.
I have a software on my windows laptop that work with external gps.
Can i use my galaxy note as an external gps for my windows laptop ?
Thank you
use bluetooth
yes i have read several places of others using bluetooth to send the gps signal to different phones. should be the same if your laptop has bluetooth. if not you can always get a usb bluetooth dongle. the captivate's gps was horrible and many people used older phones with better gps through bluetooth to improve their navigation.
