I'm jumping up and down in excitement too! This will be so much fun. I'll be your guinnea pig any time :)

Nice post! I love narratives of working out how to get shit running.

You should've opened my zip! The Bluetooth stuff wouldn't have done much for you (the sample code you used does pretty much the same). But I did have code in there for posting to Blogger API... it would've saved you some time.

The "Throwable" tip is *very* nice. I've run into the "disapearing app" problem lots of times - it never dawned on me to catch Throwable.

You're working on *which* Nokia phones? They're not generic - even the Series 60 phones. Each version is slightly different than the other one. Something that works on the 3650 won't work on the 6600, bugs in the 6600 aren't in the 7610, but might be in the 6620, etc.

When you get to the part of interpolating over the points on a map and converting from lat/lons to pixel coordinates, taking into account the curvature of the Earth... don't call me. I've played that game and I'm not good at it. ;-)

Nice post. You can get the j2me compiles happening on your mac. Its a little bit of an effort but you basically take the classes.zip and the various external classes from the nokia dev kit and put them in the wtk on the mac. Reference them in the classpath and you can then use javac or ant/antenna etc to compile and run the preverifier. Then bluetooth the jar to your phone. Its not as nice as the compile/test/fix/compile/test/fix cycle on the emulators but for a mac developer its not bad.

Nice one! Gotta get you and Jiri Komzak (Mr HitMaps) to work together... I'm pointing him to this right away...

Hi,

I have been developing with J2ME for some time and would love to look into developing something like this further.

Would it be possible to obtain a test version of your application to try out?

Thanks,


Pete

This is a really great idea -- and very a helpful article! I'm completely new to java, and was looking for a way to code a bluetooth clicker for my laptop: this was one of the first results on google, and much appreceated. As Pete says, "Would it be possible to obtain a test version of your application to try out?" Or some source please -- I'm struggling!

Thanks,

alex

Oops, the comment-forwarding on this post wasn't being handled right for this post. The 'Pho' part of the title was causing it to get stucking into my "Pho:" mailing list folder instead, so I didn't realize I had gotten any comments! Sorry about that.

Hiya, like all the others I congradulate you on a great writeup. I sent you an email but now I guess you get asked the same question quite a bit. If you are releasing your code I would find it very helpfull for writing my own code for my p900. mail@dave-mitchell.com if you get time. Thanks alot and I look forward to reading about your next programming challenge.

Hi, I stumbled across this page (again) while researching a bit on J2ME / Bluetooth and GPSes, so I think your strategy worked. ;) We're currently in the process of porting an existing application from personal java over to MIDP2, which operates in the same sphere. We presented our work earlier this year at "UbiGIS 2004 - First International Workshop on Ubiquitous GIS" (June 10th 2004) in Gävle, Sweden, were we has done something very similar.

The currently live gateway into our repository can be seen at:

http://www.onemap.org/ch/geometa/browse.php?WMS=Demis

And our presentation etc is available at:

http://www.onemap.org/pages/Archive.html

There is also an article on the way that we have written about the project and metadata in MMSes, which should be published in an upcoming geoinformatics journal. The concept is the same, and this is indeed very much fun :) Hope to see people discover even more fantastic uses for this technology in the future, and don't hesitate to contact me for further information!

nice post! can the JSR 179 do someting for this topic? I am thinking to wrap a BT GPS receiver as a JSR 179 services on the handset. Then, the user/application should get the location more easily.

Wonderful! You described so many details that I experienced recently too!

BTW, do you know if btspp://where;1 can access any bt gps receiver? If the BT is class 2 and have no security requirement, we can for sure, but if it is class 1 which usually has higher security level and needs "Authendication", JSR82 leaves the BCC implementation to vendors and does not give you a way to input a password for pairing even though you know the password. Do you have experience on pairing BT devices from j2me level?

Thanks,

Hi,

I am now able to establish a Bluetooth Serial Port connection to my Belkin GPS device and read the NMEA codes, but I seem to have to make 2 connections to make sense of the data.

The first time I connect and receive data back, the codes seem mixed up.

The 2nd time it is fine.

Does anyone know if it is some how necessary to initialise the device first in order to receieve the NMEA codes properly?


Thanks,


Pete

Hey
First of all, Great post.
Second I am doing almost the exact same thing for a project ( I need the GPS to tell the PDA to tell the labtop where it is, all through bluetooth).

If you had any ideas/comments besides what is written above, could you plz send them to me. If you had any code/examples, old versions, ect. that you are willing to send I'd appreciate it.
e-mail@s4i75@unb.ca

Thanks in Advance

hi, it's an excellent article, I really want to learn about it, can you send me the source code, or part of if?? Thanks. pablogil@grupomovil.net

Hi, this is an excellent article. Thank you for including all the useful URL to the resources you used in this project. As some people have requested, can you please post or send me (tygerzone@yahoo.com) the source code for this project? I am working on something similar with PDA and is struggling...

Thanks in advance.

Great, any hints or experiences with sonyericsson devices? I'm Especially interested in K700i and similar (no pda)
thanks

I'm a Stanford student working on a GPS/Bluetooth project and it would be very helpful to get a copy of your source code. Please contact me at jje (at) stanford.edu if possible.

Thanks,

Hi,

I'm working on project using Nokia phones for geo-based tracking and communication. I've would be more than happy if I also could get a peek at the source code for project.

Thanks,

Hi, I was reading your story while searching for a subject for my graduation paper. I absolutely wanted to do something involving mobile technology and GPS and one of the first things a stumbled in was your narrative story. So i've decided to go with your idea and maybe updating it a bit. So if you are willing to help me in any way possible (giving the fact that i'm brand new in j2me) here's my email adress: sorinbuiga@yahoo.com
