Does anyone know about the problems with using GPS and text output of the lon&lat info in a J2me app?

Site looking nice and with all the new phones and Gmaps this app is a natural. Not to mention the new wireless broadband speeds.

What kind GPS are you using? Bluetooth-connected, or some built-in AGPS features of the phone?

Cristian.

Thanks for responding so quickly. I have a courier company with about 25 drivers. Our solutions are many, but there is a common problem with the apps that I have tried on PDA's.

First of all the data is usually bad or out of date. Second the routing is does seldom accommodate traffic patterns. We often find that the last minuet course corrections we have to make confuse the apps.

I use several map programs in the office but while difficult to create routes, Gmaps has up to date data vs an upgrade path. I think in time Google will become more user friendly, but if there is a driver(courier) based solution that shows your current location and the target the driver can make due. A suggested route would also be helpful.

The app export of data would provide me a means of seeing where the drivers are.

As you can see I am open to any possible combination of hardware and software to do the job. Nextel, in our business, is the standard but it is expensive to use and lacks these specific features.

Is there any way to use a cellular PDA(BT enabled) with a BT GPS sensor inside a J2me app?

Interesting application. I would prefer AGPS support.

Some phones uses JSR-179 (javax.microedition.location) and others a special API. Motorola uses the following API's on some phones: com.motorola.location or com.motorola.iden.position .

I'm using a Motorola E1000 with inbuilt AGPS. The needed location API for this phone is com.motorola.location . Suprisingly it can be found in the A925 SDK package (accidentaly ?) from http://www.motocoder.com . The direct link is: http://trix2.cellmania.com/downloads/downloads/files/A925SDK.zip . You will find the location API after installing the SDK in the file j2me-debug.zip (located in epoc32\tools\j2me\ ). I noticed that the location API has been taken out from the E1000 developer guide. But you will find it anyway explained in the A1000 developer guide ( http://trix2.cellmania.com/downloads/downloads/pdf/DG_A1000.pdf ) or in the earlier version of the E1000 developer guide ( http://rapidshare.de/files/5834532/DG_E1000.pdf.html ) . To access the location API (com.motorola.location) you need a signed midlet (normaly). Some guys found out that it's possible to change the access rights for the midlets without a signature. So now it's possible to access the location API without a signed midlet.
You have to patch some files with the following tool: http://rapidshare.de/files/7503514/Motomu.rar.html . Here a little manual and some more information: http://www.3g.co.uk/3GForum/showthread.php?t=28619 . You will find EmGPS on http://rapidshare.de/files/7503607/EmGPS.rar.html .

Hi,
my phone doesn't support JSR-179, it however support bluetooth GPS. I've also tried a pretty cool midlet on this page -> http://www.hcilab.org/documents/tutorials/BT_GPS/BT_GPS.htm
source code -> http://www.hcilab.org/documents/tutorials/BT_GPS/src.zip

Do you thing, it's possible to add this code to mgmaps like
Mobitrack ( http://www.unteh.com/products/mobitrack/ ) do ?

Get the newest MGMaps and try it, it supports bluetooth GPS! I'm currently working on adding JSR-179 support too.
