Hello!
I've read many posts about using S730 with GPS over Bluetooth but has anyone used a USB GPS receiver?
For me this would be very handy since this would consume less power (I assume) compared to using a Bluetooth connection.

hello,
locking for the same. Send and receive data via mini USB connector for use a Garmin Vista, Usb memory stick, Adapter for serial connection for older Garmin and other devices.
Any solution possible???

Hi there,
let me first thank you for this great site you put up here!
And here comes my question:
I want to hook up my USB GPS Mouse (made for the notebook -
meaning it get's it's power via USB) up to my XDA.
And now I wonder if I can simply solder the data +/- cables
from the USB Mouse to the USB data +/- pins on the XDA plug
(so I could still use the same cable for ActiveSync on the PC),
or if I have to solder the data +/- cables from the USB mouse
to the serial RX/TX pins as described on the 'The XDA's connectors'
page of this site...
I was planning to hook both the GPS and the XDA up to my car
power adaptor in a kind of a Y constellation:
::::::::::::::::::::::::::::::::__________ Power
:::::::::::::::::::::::::::::::/
::::::::::::::::::::::::::::::/
::::::::::::::XDA ----------
::::::::::::::::::::::::::::::\
:::::::::::::::::::::::::::::::\___________ GPS
and use Power for both.
Maybe someone can tell me about the data hookup.
Thanks, Lars.
I don't have answers but some things you have to consider.
1) The XDA is a slave device. I presume the GPS receiver is one too. I really wonder if they can communicate with eachother
2) Based on how you describe this you want to power the receiver from the the car. I assume you have checked the right voltage requirements for the receiver and that the powersupply can deliver the currents required for both the XDA and the receiver. My personal experience is that the latter shouldn't be too much of a problem, but it can't hurt to check.
3) Combining USB and Serial the way you describe it is not a good idea. (mark the last character '.' as in PERIOD).

Power Supply
Hi Robert,
thanks for your suggestions.
Indeed both (the original ActiveSync cable from the XDA and the
USB GPS) get their power off a USB port on the notebook so
this must be the same voltage requirements.
This ActiveSync cable is a combined car charging cable with an
USB 'A' type connector on the end which you can plug either into
the USB port on the notebook (where it also ActiveSync's) or into
the car's power adapter (where it only charges).
So this both same voltage. And the car power adaptor should
nominally supply enough power for both...
But I don't understand what you said about it not beeing a good
idea to hook up the USB data to the SERIAL data.
When plugged into the notebook in WinXP the USB GPS installs
a 'Prolific USB-to-Serial COM5' to emulate to the programms
working with it a com5 (or com1 or com2 depending on your
hardware settings) communications port. So I guess the data
coming from the USB GPS is just the same as if delivered via
serial cable and all the driver does is faking to be a serial port
to any programm asking for data from com5.
And I think a USB device is 'not really' a passive device as it starts
popping out ASCII data strings as soon as it get's power (no matter
if there is a device to read the data or not).
So I figure when you plug it into the XDA and tell the XDA by means
of USB wakeup (USB_VDD pin 13) that there is an active USB
connection, that it will start trying to figure out what the heck the
connected cable is trying to tell it.
And here is the tricky part where I don't know if the XDA might not
believe it is beeing Sync'ed and therefore starts ActiveSync.
Anyone with any experience or suggestions there...??
(Sorry for the rather lenghty post)
Greetings, Lars.
Lars,
seems like you got the power all figures out
regarding the usb/serial discussion.
If I understand you correctly you can plug the USB connector of the GPS receiver into the USB port of the PC.
'somewhere' in the PC this is modified into a virutal serial port in order to enable serialport aware programs to work with the GPS receiver as well.
This is a good concept but at an electrical level that still means that the GPS receiver is connected in an USB fashion. There is nothing Serial Port about that. In a way you already pointed that out in your messages by using the word 'emulate'.
You can hook it up to the USB part of the XDA but still I doubt about the master/slave discussion of USB.
Regards Robert
No cahnce.
Save yourself time/money.
Forget it.

Guess U R right
Hi Guys thanx for the feedback,
I spent an afternoon researching on this stuff and am very disappointed that I have to admit you are both right.
Now way (other than putting some 'intelligent' converter between the USB GPS and the RX/TX pins of the XDA) to make the USB 'language' sound like 'SERIALean'.
I think there should still be a possibility:
Let everything run via the USB, persuade the XDA it's not ActiveSync talking to it and write a driver that talks to the GPS via the open USB connection and sends the proper commands to recieve the NMEA ASCII.
And then you would still need to tell your route software to take the incoming data from the virtual (or emulated) COM port...
And when I read the above chapter once more :shock: I find this is definitly not a job for me!!
So I will just get a serial GPS an hook it up the nomal way.
Cheers and thanx again, Lars.
Hi,
Just read your post. I am new to pda land. Just bought a xda2
I have a laptop which I use with a gps usb mouse via usb on the laptop. Am I right in thinking that I could have bought a ps2 mouse and used a ps2 changer to usb and it would have worked??
If so can't I buy a usb to ps2 changer in order to plug into a car connection cable which has the ps2 and the xda conection and a ciger lighter plug for power? OR is there a similar cable for a usb connect for gps?
Am I missing something here?
Thanks

I have a Garmin GPS 18 USB Laptop Receiver which is a GPS receiver with a standard USB adapter on it.
Has anyone tried to use a female to male mini adapter and plug this into the mogul.
I have the Garmin Software for the mogul, but would this work and be able to be picked up by the software.
Also what would you suggest for drivers
Adapters don't matter if the device won't work that way.
These phones are designed to be a USB Client Device. Not a USB Host Device.

Alright, thats all I needed to know. Sounded like an option, I think Im just going to give navizon a try
GPS fix for you if you have the snarlgies
Snarglies: /noun/ from the remulak vocabulary meaning balls ;-) The reason I say this is because there is on this forum a ROM and radio update that will enable GPS (internal) and REV-A (faster EVDO) features of your unit.
So at home, in some remote rooms where my Wi Fi doesn't reach, I have a dLAN going through the power supply... Which I usually use to connect my PC on...
Also, when I connect my TD to my computer, it uses the Internet connection for all data transfers.
So my question is : Rather that having to turn on my computer to have Internet access on my Diamond, is it possible to use directly the signal from the dLAN (it's a Devolo one, so it has a RJ 45 connection, and a USB 2.0 so I guess some USB 2.0 <-> Mini-USB adaptator should exist) on my Diamond?

I strongly doubt that you can use the USB connection, because the dLan device needs to be connected to a HOST-enabled USB port, which the Diamond simply does not have.
But there is an even better solution for you, which even frees you from any wires...
---> Connect a WiFi Accesspoint to the RJ45 of the dLAN, use the WiFi in this new area to connect to the Diamond....
Good Luck
That's what I'm planing to do anyway, but 100 euros is a little to much for a simple range extender knowing that a WiFi router costs about 50 euros...
There's a Belkin one on ebuyer.com for £30.99
Has anyone gotten usb working with a wifi adapter? There are many situations where my phones wifi just doesnt reach. I would like to be able to hook up an external adapter to use.
Hello, I have an idea how we can make the current Android Auto completely WIRELESS.
Idea is as follows:
Plug a micro Dongle in the car's USB port.
The Dongle will essentially be a WiFi Tranciever. (it may need custom code/firmware etc.)
The Dongle will talk to the Android Phone over WiFi (Because Bluetooth is already being used by Android Auto).
A custom program will be running on the Android phone to send ALL USB Data to the Dongle using WiFi.
Suggested Dongle models:
Xbee, Arduino with WiFi module, any other similar board, possibly any cheap Chinese WiFi USB dongle available on Ebay/Aliexpress.
Things to consider:
The Car's infotainment must recognize the Dongle when it is plugged in as a "USB device" (not a USB Stick/Flash Drive !!!)
The Dongle may need custom code/firmware that will start sending packets to the car's infotainment as soon as it is connected/powered up/car ignition is on, in order to Emulate a phone running android auto.
In the mean time, the app running on the phone will already be connected to the Dongle and the two will be talking to each other.
I you have any other suggestions, leave a comment bellow.
PS: Such devices (USB Over the Air) are actually available on the market, but are quite bulky. We need something smaller.
But even if it is big, we can use a Micro USB plug like this one with flat cable, that will run in the Phone tray, where the board will be hidden so it will not be visible at all!!! :good::laugh:
https://www.aliexpress.com/item/4000325524998.html
Just cut the other end of the flat cable if needed and solder as necessary.
Again, if you have specific ideas/suggestions leave a comment bellow.
