Changelog

    - midlet is signed
    - several projections support: Latitude/Longitude, Mercator, Transverse Mercator + grids: GK, SG, BNG, UTM
    - custom datum support
    - HPS improved (walking direction-oriented, provider status, compas)
    - midlet runs on Motorola A780
    - ... I do not remember.... many small improvements


Signed midlet

Midlet is now signed, so you have to install it using JAD file. The main benefit of signing is for Nokia and SE phones owners - they can finally assign the midlet "never ask" permission for file reading/writing now, to get rid of tile loading and tracklog creation confirmation prompts.

If the installation fails for you, your phone may not have Thawte CA certificate in midlets/java trustore. Check it first. If it is not there, have the firmware updated. Or, eventually, do not use JAD or remove MIDlet-Certificate-*** and MIDlet-Jar-RSA-SHA1 lines from it.

Custom datum support

Via JAD, you can define custom datum. The format is

Code:
Datum-N: <name>{<ellipsoid name,dx,dy,dz}=map:<cname>


where

    - name: datum name as it appears in TB (Options->Settings>Default Datum)
    - ellipsoid name: name of reference ellipsoid for given datum
    - dx,dy,dz: parameters for 3-parameter transformation to WGS-84 datum
    - cname: datum identification in OziE


See JAD for example.

Ellipsoids names

Code:

Airy 1830
Modified Airy
Australian National
Bessel 1841 (Namibia)
Bessel 1841
Clarke 1866
Clarke 1880
Everest (1830)
Everest (Sarawak)
Everest (1956)
Everest (1969)
Everest (Singapur)
Everest (Pakistan)
Fischer 1960
Helmert 1906
Hough 1960
Indonesian 1974
International 1924
Krassovsky 1940
GRS 67
GRS 80
South American 1969
WGS 72
WGS 84


These datums are predefined: AGD 66, CH-1903, NAD27, OSGB 36, RT 90, S-42 (Russia), WGS 84.

Expert features

If device discovery fails or you want to try to use serial port GPS, connection string may be set manually in the JAD using the following properties:

Serial port GPS example
Code:

GPS-Connection-URL: comm:com0;baudrate=19200
GPS-Device-Name: SerialPortGPS


Bluetooth GPS example
Code:

GPS-Connection-URL: btspp://00803d000001:1
GPS-Device-Name: WeirdGPS


These settings overrides "last-known" device info.

0.9.5 download link

2007-01-26 20:20 minor update
    - fixed backlight control for SE
    - accuracy (in meters) is now shown in HPS for internal provider instead of "1.0" constant (remember, for external GPS provider hdop is shown)


0.9.5a download link

2007-01-31 21:10 minor update
    - fixed distant waypoint mark placement in HPS
    - accuracy of positions reported by GPS (not the calculated average!) is now shown in HPS also for external provider; accuracy = hdop * 5 m (typical accuracy of consumer devices)
    - fixed missing Start command on SXG75 in fullscreen mode
    - fixed a"bug" that forced defensive filesystem access on all devices, not only SXG75 (you probably haven't noticed anything anyway)


0.9.5c download link

Kruch,
I can reproduce a bug with crosshair position movement known as plord map position jump (when switching maps in atlas).
Scenario:
- first is necessary to use NMEA log to have last stable (standing) position from provider simulated
- when log is replayed, just start to switch maps
- after map loads, crosshair position can be moved a little if "5" key is pressed, but OSD values doesn't change ???

Seems that first crosshair position after map switching isn't updated to last known GPS position. Not so visible when GPS is on, postition is updated every one second.

But with GPS off, it is possible to have almost any crosshair position coordinates for the same point. Sample attached.

Bug 203 posted.

I could not find easy to 1) use 2) and deploy 3) and integrate with phpBB forum bug tracking system; let's see how "topic-based" bug tracking will work Confused

Mantis MOD for phpBB is not developed anymore I think, and according to last messages in its thread on phpBB site is has not been left in a very good shape...

Kruch,
What about otherTB's improvements already asked like:
- continous maps (with borders) scrolling
- preserving almost exact crosshair position when switching maps
- new Settings for maps, ie datums, projections, coordinates
- extended .gmi support etc.

Possible ?

Once more. Maybe is better to have all wishes in one place, like bugs.

Yes, possible.

"improvement" is a bug with "ENHANCEMENT" severity for me, so I'll convert this list into a few enhancements.

It's "Start <New>", but it doesn not seem to fix to your screen width. I'll see if I can control font size for command labels...

Kruch,
Could you check last used GPS provider in 095 (k750i)?

Edit: My fault, no TB restart Embarassed Sorry, I'm little tired today.
Or my HDOP is near 10.0 Exclamation

Hi kruch,

first of all, once again, thanks for this great work!

Question 1: do you think the problem for sxg75 can be solved to read maps from memory card? Because my atlas is growing and growing and memory is getting smaller.

Question 2: is it correct that at the moment only one waypoint is shown (Navigate To) and not all of the loaded list?

By the way, what do you think about creating a logo for trekbuddy?
If you want I can make a draft.

Bert

A1: you mean the problem that the application fails to read more files from memory card after some time? Do you have the exception it throws at hand so that I do not have to search forums? Thanks! Or you can a post a bug to Bugs forum, with details Wink

A2: there will be a new option for showing all wpts
