A device with J2ME run-time platform which must have the next specification:

• MIDP 2.0 / CLDC 1.1 with enabled APIs :
  • JSR-135 (Media Package)
  • JSR-82 (Bluetooth Package)
  • JSR-75 (File Access Package)

Installation

Use the habitual mechanism to install applications in your device, for example, with a Nokia terminal use PC Suite. Once installed, in some devices you must configure the permissions to grant access related with bluetooth connection and file system access. Consult the manual of your device.

Currently, the application isn't signed, and consequently verified by third parties. It's possible that each time that the application need to access to external file (when open a file to store route or for load a map, for example), you would be asked to accept the operation.

Keypad

Application uses the key map shown in the graphic.

Screened button execution:

• Button '1' : Used to execute "left screened button".
• Button '5' : (Fire button) . Used to execute "center screened button".
• Button '3' : Used to execute "right screened button".

Cursor movement:

• Button '2' : To move up.
• Button '8' : To move down.
• Button '4' : To move left.
• Button '6' : To move right.

Miscellaneous options:

Each screen can offer some functionality through buttons '7', '9', '*', '0', '#'. See detailed documentation of each section.

Some terminal have more button, like a cursor and command button for hand-up, call, etc... These buttons are very dependant of each device, eGPSTrack try to use them, but it's possible that doesn't work correctly, in this case, use numeric keypad as explained above.

Help on-screen

By default, button '#' are programed to show a minimal help on each screen.

In any moment, if you don't remember the available keys, simply press '#'.

Configuration

First time you use the application, some parameters must be configured before normal work. When application is launched, in main screen you can see the basic available options :

• Configuration
• GPS
• Map
• About

On configuration, some behaviour parameters can be modified.

Use key 0 to reset values to default.

Each option are:

Search GPS

This version only works with external GPS devices connected through Bluetooth. Enable Bluetooth before searching device and after, in Configuration > GPS , click " Search " button and wait some time until the bluetooth found devices are shown. Use cursors to select one of them, and when selected ('use' option) the application will return to main Configuration Screen.

Generic Folder

Selecting this option, a file browser will be shown to select a folder where route log will be stored within. This folder will be the start folder when in Map Screen 'load map' button is pressed.

Capturing interval time

• Log Time is the time, in seconds, between two samples of GPS information stored into external file.

• Map Time is the time, in seconds, between two samples of coordinates shown into map screen.

GPS Reception/Statistics

In main screen, select GPS to visualize the screen which enable to you the controls to start/stop GPS reception , start/stop the external route writing or visualize the current statistics.

When the Fire button is pressed, after some time the information on screen will show the current position received from GPS , and with a regular interval (Log Time configured previously) the values will be actualized.

On screen, current position, velocity, altitude and direction are shown directly from information of NMEA183 sentences received from Bluetooth GPS Device .

With left / right you can switch between statistics and current status :

In this screen are shown the distance accumulated in current travel, ascent distance, descent, averaged velocity (average of speeds when velocity was not zero) and accumulated average velocity (distance / time).

The left button on this screen is to control the route write, STPlog for stop writing, and STRLog for starting. The status of capturing are shown in all application screens, in the upper status bar. The two left icons are related with connection status :

• A Red circle : No connection established.
• A Green circle : Connection established.
• A Red square : No route write enabled.
• A green triangle : Route write in progress.
• Two red columns: Write stopped/paused.

In addition, in this screen some extra functionality are available by means of keypad buttons:

• Key 7 : Route log file, truncated, a new file will be created.
• Key 0 : Statistics reseted to 0.
• Key Star : Insert a waypoint with current position. A name is asked before insert the waypoint into log file.

Trek log file

Route are stored in NMEA183 format, you can use GPS Babel to convert them to any other format, for example to use with Google Earth .

Log files are created with the generic name: gps_year_month_day_hour_minute_second.log. The place folder is configured in Configuration Screen.

Maps

Calibration

eGPSTrack v0.3 has its own format for calibrated maps, you can use eGPSMap generator to generate them, but if you already have raster maps, you can made by hand a file to be readed by eGPSTrack, is too simple, as shown in the example :

eGPSTrack-0.3
garriga.jpg
41.68645 N, 2.2920 E
41.68045 N, 2.3000 E

First line must be the literal ' eGPSTrack-0.3 '.

Second line must be the filename of the image of the map¹.

Next lines are the calibrations, in this version, the calibration is based in two coordinates: upper-left corner (in the example " 41.68645 N, 2.2920 E ") and bottom-right corner (" 41.68045 N, 2.3000 E "). Coordinates must be in Decimal degree format.

The file, must has the termination " .egt ".

Application doesn't implement automatic Datum conversions. Map calibration and Bluetooth GPS device must be in the same Datum , generally WGS84. In another side, to calculate acumulation distance , application uses formulas based in this WGS84 datum, if the Bluetooth GPS works with another one, acumulated distance will be erroneus.

Map Screen

To view maps and the current route, select button Map on main menu. In this screen, left screened command buton are enabled to load egt files , click it and select the desired file, when selected, map will be shown, remember that in this version, in some devices, you could be asked some times for grant permissions over filesystem acces.

In this screen , the route made are painted with points, the color of point will change to inform about direction of trekk . On upper-left corner an arrow show the actual direction.

The extra controls available in this screen are :

• Direction buttons : To scroll the image.
• Key 5 : To center the image and route.
• Key 7 : To zoom it the image.
• Key 9 : To zoom out the image.
• Key 0 : To restart the map route logging.
• Key star + 4: To enable/disable raster image loaded.
• Key star + 5: To enable/disable Height's Map.
• Key star + 6: To enable/disable Waypoints labels.

Height's Map

In Map Screen, when combination star + 5 are pressed, the height's map is shown or hidden.

The graphic is painted with altitudes logged in map route, remember that with Key 0 the values stored will be removed and a new route will start again (this is a "virtual" route, persisten logs that are managed by means of GPS screen are diferent from the ones explained here)

Waypoints

It's possible to insert waypoints manually in current trekk logging, by means of pressing key Star in GPS screen , the waypoint will be inserted in log file using current position provided by GPS. Application will ask for a name for the point. This name is showed in Map Screen (with the combination star + 6 labels can be enabled or disabled)

1. PNG, JPG, GIF image types are supported. No restrictions over the size of map are assumed, only the memory needed for loading and displaying, and this factor is determined by Device, on Nokia 6230i , where application was tested, maps over 800x600 are loaded without problems. on N70 1024x1024 images can be used satisfactorily.
