NMEA Out Option on GPS Enabled Phone

Postby RenegadeWiFi » Fri Dec 28, 2007 10:49 am

I wanted to reply to a different thread but it had been locked with some not totally true (or perhap just out of date) info in it.
http://www.netstumbler.org/f9/nextel-i730-gps-22905/

I have a Boost Mobile Motorola i425e
The GPS in my phone can be used for tracking my phone personally through the internet with a 3rd party app installed.
In my GPS Options, I have an option for NMEA out.
The phone uses a standard mini USB port for connecting to the computer, I have already used it as a modem and used the cable to upload apps and ringtones and the like.

When I enable NMEA out, an icon shows at the top of my phones screen.
In Microsoft Streets & Trips, scanning for a GPS receiver finds the GPS on my phone on COM Port 3.
Only problem is that icon goes away and the GPS is no longer recognized until I turn the NMEA out option off and back on, but then the process repeats.

I haven't gone through all the possible settings in Netstumbler yet, but I have not gotten Netstumbler to see it yet.

I have read you can buy a special cable to use the phone as a GPS reciever but you can't do it with the standard USB cable. I'm not opposed to buying the cable, in fact I am going to return some gifts shortly and may buy one today if I can find a store that has it.

The purpose of what I am writing here is to start a conversation and see if anyone else here has tried what I am talking about. Seeing the thing recognized in S&T gave me the idea of "Where there is smoke there is fire" and I'll bet with some determination we could get this to work.

Someone said in the other thread even if it worked it wouldn't work as good as a real GPS receiver, I'm fairly sure of that too, I just think this would be cool to do and would bring GPS to a lot more users if it worked at all.

Using a program called XPort I can get Netstumbler and Microsoft S&T to see the GPS simultaneously, and without the NMEA Out Icon shutting off, however neither of them are getting a position from it yet. Of course, I've been doing this from an indoor desktop, but I don't think that is why I am not getting a fixed position because my nav software installed into the phone (Mologogo) gets a position and I can see my Lat/Lon position in the phone.

XPort can be found here, XPort
I used to use it with my Delorme USB Earthmate when I wanted to run Navigation software and Netstumbler at the same time.

I posted the same thread on HowardForums under the Boost mobile section.

I'll check out GPSDiscussion, thanks!

Blackberry GPS Tracker - Home is what I run on my Blackberry for my wife and kids to see where I'm at. We all look at it like an additional safety device for me.

I have something similar, Mologogo. But what I am trying to work out here is to use the phone as a USB GPS Receiver to use with Netstumbler and/or a PC Navigation program like S&T

Someone on another forum made a suggestion and I followed up on it, I'm posting here for this forums benefit

Max wrote:without googling, as I understand the NMEA data is just ascii text which you could see in an app like hyperterminal. I'd get the device attached to your laptop and see what your laptop has for the Com3 port, then tell HyperTerminal to listen to that port, and put the phone near a window.


Good advice...

Below is an example of the data coming through the COM port, Netstumbler and Streets & Trips still recognize it as a GPS receiver but still don't get a location...

EDIT

I had originally posted GPS Code here, but it would have given away my location

Yup, that's standard NMEA sentences.

Sometimes I really like cell phones, and change it often.Last year i got a LG Chocolate one, but at my angry moment i throw it away, so it died! And this year i bought this kind of cell phone with cheap price, but i am afraid of his fate then. I hate the noises of irrelevant calls,you know sometimes i just want to be alone, that is enough, anyone knows how can i do? I have got a cell phone jammer in Google, but I heve no idea of it, ask some profession for help!

Have you ever heard about the RF jammer kit? And do you know in what aspects it can be used for and where can be the best place to own one high quality and multi-functional RF jammer? If so it is really necessary for you to come, stop your step here and know more about RF Jammer, and seize the chance of getting this high quality product from here.
