Is there somewhere a list of compatible CF GPS cards for Zaurus ? I am looking over ebay and sometimes some GPS cards go out for only 30$ but I don't grab them out of fear of not working under Zaurus (I use cacko 1.23 on a 3100) I know that the software support is very weak and poor, but even them I'm interested in the GPS card as I know is only a matter of time before someone adapts Tom Tom Go or something like that.

So my question is, can I grab any GPS CF card and use it or I need to check for special drivers for the zaurus in wich case where can I find a compatible list?

thank to all.

Ambicom CF-GPS card works well on my C3100 using Cacko. I use zroadmap & qpeGPS.
I got mine at Staples. (office supply store)
It came with 2 CDs of maps and routes, but the included software and maps are only usable on a Windows PDA

I think the Pharos igps with the cf adapter will work. Will check when I get home. I've heard that it will work with the usb cable if you can hack the pl2303 driver. It worked for some with the SL-6000. This is the same gps that comes with Microsoft Streets and Trips.

I am looking for a gps solution that is external to the zaurus (mainly not to use the battery to much) and also don't want usb/serial cables hanging about.

Is it possible to use a motorola A1200 phone? This has gps build in and it would be good to have a shared device for net connection/GPS.

On a related point, is it possible to have two simultaneous bluetooth connections?
ie; one for the net (GPRS) and one for GPS? I use a socket rev K CF bluetooth card with a sony ericsson v600i at the moment.

Is there such a thing as a dual bluetooth card with independent channels... is this at all compatible with the Zaurus (3100 with pdaXrom)?

As always, I'm very happy to compile howtos and documents if I can get this working, just need a hand with the first part of the problem....

My aim would be to have GPS with something like gpsdrive that could download maps on the fly and report my position back to a server.

Thanks for your ideas

Most phones won't let you use the built in gps as a gps.

Kind of an old thread, but what do people recommend for GPSs? I'm thinking about getting one and have one suggestion already, but that is for a bluetooth GPS and I'd rather have USB. What I want is:

-USB (not bluethooth)
-Works well with pdaXrom
-The ability to upload data to Google Earth or a similar app ( not compiled yet is OK)
-Externally powered would be nice, or not too draining on the battery

Thanks for any input.

Hum .... those are 2 questions really .... the map thing is independent to the GPS receiver, unless you're looking for a complete GPS navigator with usb connect capabilities to Z/PC ?

Looking at the other requisites it looks like you just one a usb gps receiver ... I read somewhere amongst the OESF forums threads that someone had success with some usb gps receiver.

Regarding the software ... that's a different story: as to my understanding there is some open source software that can do navigation (not just moving map) but it's only usefull it your Z can connect to internet or route recalculation cannot be done (look at maemo-mapper for example).

So unless your Z can do umts/gprs or some sort of other cheep wireless connection to internet while on the road the answer is that there is no open source software that can do navigation on your Z.
Capn_Fish
I don't need navigation. Sorry, I'm kind of new to GPSs, so most things I say will probably be quite literal. It appears I am just looking for the receiver.
louigi600
snoop around in the forums ... I've forgotten where I read that someone had success with a usb gps receiver.
Capn_Fish
Once again looking into GPSs, so, any more suggestions for USB GPSs? I'm not getting much on the forums here, only CF GPSs.

Thanks.
pelrun
There aren't any real model variations as far as the Z is concerned; you really only need to choose based on chipset(go MTK or SiRFStarIII) and price. Any USB GPS 'mouse' will present itself as a USB serial device to the kernel*, and will spit out NMEA data when opened. And everything understands NMEA.

Installing gpsd is a good bet; many linux gps utilities use it, although most can be configured to read the GPS serial device directly.

(* there's a chance that the USB serial chipset might be unrecognised by linux, but I think support is getting very good these days...)

The bluetooth GPS units are essentially identical; but use a BT serial link instead of a USB one.
Capn_Fish
So basically if I go and find the cheapest USB GPS receiver I can, it should work?
pelrun
Yup. All the usb gps mice should be quite cheap these days, under US$50, although at the moment ebay seems to have a bunch that are even more expensive than the BT equivalents (!?) Be wary too of sellers misrepresenting the chipsets - there's a *massive* difference between SiRFStarIII and SiRFStarII, for example.

If you can wrangle an MTK or a SiRFStarIII chipset then you probably would never need to upgrade; they are mind-bogglingly sensitive and quick compared to the older ones. But my old usb and bt units are both SiRFStarII's and I've never had any functional problems with them - I just can't use them whilst indoors or tossed in the glovebox or my backpack biggrin.gif

i'll try tonight to plug my Holux GPSlim gps to my zaurus ! it's a bluetooth gps receiver but it has also an usb output. i'll let you know about it !
(it works yet under bluetooth)
Capn_Fish
Awesome. Thanks!

Awesome. Thanks!


so here is what i have when i plug the Holux into my usbhost :


QUOTE
usb 1-2: new full speed USB device using pxa27x-ohci and address 100
usb 1-2: device descriptor read/64, error -62


perhaps it needs a special driver? holux talks about a 2.4 driver but nothing for 2.6 kernel... perhaps someone could check the 2.6.23 kernel config ?

EDITED: found the linux driver here : http://www.holux.com/JCore/en/support/downloadCenter.jsp
perhaps some skilled people could compile it for us ? wink.gif

I'm thinking that one looks good (not too expensive, SirfStarIII chipset, reputable dealer).

Sorry, I can't compile your driver (I'm not using Debian).

EDIT: Any idea on the power draw of these things? It would be unfortunate to get one only to discover it draws more that the Z's USB will output.

I don't think there's really any standard for serial over usb, so you need a driver for whatever is in your device. For example, to use an itrek-z1 over usb under linux you need the cp2101 driver in the kernel.

You should check out the itrek-z1, it outputs NMEA over usb and bluetooth, is self-powered (with solar panel for extra life), can records tracks itself, and there's java software to config the device and download tracks over usb and convert into a kml google earth file.

I thought that went without saying - but the chances of running into a chipset that linux doesn't support are pretty slim these days (usb-serial.o handles *heaps*), especially in the cheap-usb-gps space. I don't particularly see it as something to worry about. smile.gif

Capn_Fish: you should have no problems with the GR-213. It's got a PL2303 serial chip in it, which is the most common one out there. Linux definitely supports it. biggrin.gif

if your only experience with usb is mass storage and ptp, where there is only one standard and drivers are common, then you might think there was a usb serial standard too and that your kernel is going to have support for it. that's not the case, and on the z getting a new kernel module isn't necessarily trivial. the device I mentioned, for example, needs a less common module, and another device mentioned in this thread apparently requires a third party driver, so it's definately something to check if you are going to buy a new device to use with a z

I was specifically referring to usb serial devices in cheap gps units - i.e. only the devices Capn_Fish was asking about. Not the more complicated gps devices, *definitely* not generic usb devices - for those all bets are off.

FWIW I have a Pharos Bluetooth iGPS working with my c3000. It worked out of the box once I figured out how to give it the so called "PIN".

I can now confirm that the above GPS works well with Angstrom (just modprobe pl2303 and ohci-hcd or whatever that module is, and it works)
