Hello List: Trying to give GpsLib4J a try with a new Garmin GPS 10x (bluetooth) from a standard vista/jvm workstation. Most of the examples under com.diddlebits.gpslib4j.test (using rxtx) seem to run OK so I'm confident that I'm communicating successfully with the device. However, ClassTester does not run correctly. I receive Exception in thread "Thread-4" java.lang.NullPointerException at com.diddlebits.gpslib4j.Garmin.GarminGPS.run(GarminGPS.java:87) when I attempt to run this test. The error jumps up when the following line is executed. GPS gps = new GarminGPS(input, output); Any tips or hints would be most appreciated. Thanks Dennis |

-----BEGIN PGP SIGNED MESSAGE----- Hash: SHA1 Absolutely, it's been at the top of my todo list. Evidently sun has sort of abandoned the javax.comm API for the last few years and although they promise to 'unbreak' it soon I think it would be wise to just switch it. So my vote is yes. +1 - -tk On Jan 27, 2007, at 2:00 AM, Patrick Valsecchi wrote: > Hi, > > I was installing my GPS app on a new machine and it was a pain in > the ass to > get it working.

Hi, I was installing my GPS app on a new machine and it was a pain in the ass to get it working. It was mainly because we are using RXTX through the java API. So I had to install both RXTX and comm jar files with a properties file. Since RXTX version 2.1, there is no need of the javax.comm API, but we need to use gnu.io instead and the rest is compatible. So we just have to change the imports in the code and it works: search "import javax.comm.*" replace by "import gnu.io.*". What do you guys think? Do we do the switch? Thanks. |

I found the perfect candidate for sending maps to the GPS. It's even in java and with GPL source code (directly in the jar file): http://www.geocities.com/garminmaploader/ I'll try to look at it and see if it can be used "out of the box" as a library. Or maybe we can ask the author if he wants to merge the two projects or if he still does something on it (last update of the web site was in 2002). What do you guys think? See ya.

I don't know, there are already some thrid party soft that does that... maybe we can find some source code... Here is what I found for the moment: http://cgpsmapper.com/ |

Awesome. :) I'm on vacation right now and more or less away from computers. Will be back next week sometime. Interested to see what you are working on, send away. :) What GPSs support it? There were parts of the current protocol I had to sniff with a serial port sniffer, bet we can do the same with the map protocol to reverse engineer it. -tk On Tue, 26 Dec 2006, Patrick Valsecchi wrote: > Hi, > > I'm starting a new Java project that may be of some interest for you.

Hi, I'm starting a new Java project that may be of some interest for you. It's a library to parse the Garmin map files (.IMG). You can have a look at it here: http://sourceforge.net/projects/jgarminimg/ Appart from that, I already have some datum/coordinate system conversion library in Java. I've put it in attachment. That library is a small part of my baby project of totaly replacing the lame application Garmin gives us to control our GPS. I've not published this application, but it's already quite in a good shape. If you want to have a look, I can send it... By the way, I'm looking for the protocol to send maps to the GPS. Does anybody has any info about it? That would be a nice addition to Gpslib4J. CU. |

Hi Todd, welcome Oliver. I've been pretty inactive lately. Mainly because the lib is doing what I=20 need. I don't care about CVS or subversion. So, if you rather have subversion,=20 feel free. I'll just check if I don't have non-commited changes before you do the=20 switch. I fixed some concurency problem (the reader thread pinging the=20 GPS while some data was sent to the GPS)...

My other sourceforge project is JavaMeasure an OO conversion utility library I use in one of my other projects (iScry at www.diddlebits.com) - might be the proper place for the coordinate conversion stuff, don't know if it adds any value besides a OO way of dealing with conversions. I like it but I don't get much activity on it - I think most people do conversions by hand. I needed to do it OO so I could use it better in beans, etc so I wrote the library. |

[Sending this to our dev list, but ccing both of you in case you =20 aren't subscribed to it.] Welcome Oliver to our little team.
