3.4 Four push buttons

Nano3 has four push buttons, which have a dynamic function.

The function of each push button is described on the blue label adjacent to the button. A
label can have two options with the second option coloured red on the label. This indicates
that the button has two functions. The blue option is operated with a short press and the red
option with a long press. For labels with two options, the second option is typically the
opposite function of the first option. e.g. Next/Previous, Insert/Delete, Ok/Cancel,
forward/backward.

The functions of buttons are mostly related the current page (waypoint, task, flarm, info,
setup). If there is no label next to the button, this button has no function.

3.5 LEDs

On the left side there are five LEDs; three green, one blue and one red. The LEDs show the
status of the NANO3 flight recorder. During normal operation, the first LED blinks when the
NANO3 is powered on. The second LED blinks when the GPS status is ok. The third LED
blinks when the recording of a flight is started. The fourth blue LED blinks when the
Bluetooth module is switched on.

Version 2.06 February 2017

Page 11 of 44

LEDs show the status only when the LCD is off.

3.6 NanoPower cable

The NanoPower cable is a special device which converts 12V to 5V providing a power supply
for the NANO3 and a PDA. It also translates a serial signal to match the NANO3 signal level
and a PDA or computer signal level.

Connect the red and black wire to 12V power supply. Red is positive.

Maximum input voltage is 24 Volts.

The NanoPower has two plugs. On one side there is a standard USB-A connector. Please
use the included USB-A to mini-USB cable and plug the NANO3 on this side. Any standard
USB-A to mini-USB cable can also be used. On the other side there is an RJ45 plug. This
plug is designed for a PDA or a computer.

The RJ45 plug is NOT designed in accordance with the IGC standard. It can be
used only with a dedicated cable. Do not plug any unknown cables in to it as this
may damage the NanoPower circuit.

4 Operation

There are two modes of operation: Data transfer mode and Normal operation mode.
When in the data transfer mode, flights can be downloaded and the NanoConfig program
can be run. Normal operation mode is when the logger is ready for recording flights.
The mode in which the NANO3 is operating can be determined from the main screen or
LEDs, when the screen is off.
In data transfer mode, the last two or three green LEDs will be permanently lit, on the
screen, there will be a message “USB connected”, whereas in the normal operation mode,
up to four LEDs will be blinking, or the screen will display data only. See chapter 4.2 for a
detailed explanation of each LED.

4.1 Powering on

There are three ways to power on the NANO3 flight recorder.
Press or rock the rocker button and the NANO3 will power on. It will go directly to
normal operation mode. On startup, a splash screen will appear with information containing
the Serial number and version of firmware. The NANO3 will then go into normal operation
mode.
Connect the NANO3 to a computer using a USB cable. It will automatically power on
and the last two or three LEDs will light up. At the same time you will see the first message
“USB connecting…” and later “USB connected”, when the connection is established. This
indicates that the NANO3 flight recorder is in data transfer mode. You may now run the
NanoConfig program or copy flights using standard methods for copying files.
Connect the NANO3 to NanoPower cable. The NANO3 will then automatically power on
and after approximately 20seconds the NANO3 will go into normal operation mode.

Normal operating mode starts with a message “Acquiring time” and “Acquiring GPS fix”.

When the NANO3 acquires a GPS fix, it will switch to the GPS info page. The user can at any
time, cancel the acquiring page by pressing any button. Acquiring a GPS fix may take
between a few seconds and a few minutes, depending on the satellite constellation and the
NANO3 position. The NANO3 has a very sensitive GPS receiver which can sometimes acquire
a GPS satellite signal in a room.

Version 2.06 February 2017

Page 14 of 44

If you press or move the rocker button or any other buttons, when in the data
transfer mode, the NANO3 will revert to normal operation mode

4.2 User Input

The NANO3 user interface consists of many dialogues, which have different input controls.
They are designed to make input of names, parameters, etc., as easy as possible. Input
controls can be summarised as:

 Text editor
 Spin controls (Selection control)
 Checkboxes
 Slider control
 Line width control
 Color selection

To move the function from one control to another, use up or down buttons. By pressing the
Edit button access to the control that is displayed is possible.

4.2.1 Buttons on Nano3

Buttons have dynamically set functions. When you press a button, on the button side, will
appear a blue labels, with the action assigned to that button in that context.

On main screen, top button always performs the function of switching between pages. Short
press will cycle in one direction between pages, long press will cycle in the opposite direction
between pages. A number of pages look similar initially as the cycling between them simply
change the zoom level. The screen will momentary will be updated to reflect the new zoom
level. The number in a zoom level icon shows us the outer circle radius (2km – depends on
distance units setting). Inner circle is half of that distance.

Middle buttons help with target selection by cycling through available targets. Lower button
has EDIT function, where we can edit/view the currently selected target.

Version 2.06 February 2017

4.2.2 Text Edit Control

The Text Editor is used to input an alphanumeric string; the picture below shows typical
options when editing text. Use the up/down button to change the value at the current cursor
position.

Push button next will move cursor right. Long press on next, will move cursor left. At last
character position, push button will confirm edited value, long press Ok C) will cancel editing
and exit that control. If Long press is available, part of button label is in Gray color. For

example above, top button’s long press >> B has back function. Bottom button’s long press
has Cancel function. Flarm ID field is not editable, because it’s unique flarm identification

number.

On FlarmView57, we can enter in Edit mode with short press, rotating knob we can change
the characters, short press will confirm current character and jump to the next position. Long
press will finish editing that field. With push and rotate, we can move cursor left and right.

4.2.3 Selection Control

With Edit you can activate slider control, then up/down buttons you can select the
preferred value and confirm it with the Ok push button.

4.3 Normal operation

During normal operation mode, the user can use the NANO3 as a flight recorder, simple
navigation, vario system and Flarm radar display. There are four pages (information page,
waypoint page, task page, setup page and flarm radar). You can read more about pages in
Ch.5.1. If the screensaver function is enabled, the screen will go off after the set time period
in seconds. When the screen saver is on, the pilot can still see the indicated status of the
NANO3 by monitoring the five LEDs. The first LED blinks when the NANO3 is powered on. The
second LED blinks when the GPS status is ok. The third LED blinks when flight recording has
started. The fourth blue LED blinks when the Bluetooth module is switched on.

The fifth LED is red and indicates an error. See chapter 8 for more details.

4.4 Battery status

The battery status is indicated with LEDs only in fast charge mode. Ch.4.7 If all the LEDs are
on, it means that the battery is fully charged. During operation, as each LED goes out it
means 20% less battery capacity remains. A Detailed explanation of the LEDs is given in the
table below.

From version 2.0 NANO3 is able to measure battery level more accurately. This means it can
calculate the remaining time of working based on the current consumption rate.
It is possible in some circumstances for the accuracy of this calculation to drift so there is a
built in ability to re calibrate the battery.

4.4.1 Calibration of battery

Battery can be calibrated in the following way.

1. NANO

3

must be fully charged

2. NANO

3

is fully charged, when charge current drops below 5mA

3. Disconnect the supply cable and leave the NANO

3

running until it shuts down due to

an empty battery

To be sure, that the NANO3 is really in discharge mode, the bottom row of the
INFO page text will show “DIP”, which means Discharge In Progress.

Version 2.06 February 2017

Page 18 of 44

We can increase the speed of the discharge cycle, if we turn on BlueTooth
module, set up brightness of LCD to maximum, turn off screen fade.

After this procedure NANO3 has measured its battery capacity and with the next charge, the
indication will be more accurate.

Calibration of battery is performed during production of nano. In case that calibration data
is wrong, calibration cycle is necessary for correct indication of the charge level.

If charge level does not shows correct value, comparing to the battery voltage,
battery calibration cycle is necessary to be done. Example: Charge level: 99% and
measured voltage 3.6V.

4.5 Powering off

Press the rocker button for a long time and the red LED and the adjacent green LEDs will
start blinking. Once you see the LEDs blinking you may release the button and the unit will
power off.

4.6 Security void

When the security (secret key) is lost at power on, the red light will be on and the remaining
four green LEDs will start blinking and “DIGITAL SIGNATURE FAILED” message will appear
on the screen. To continue press or move the rocker button for a longer period. The NANO3
will be fully functional, however the flight will not be signed.

In order to produce the IGC-certified files, the NANO3 flight recorder must be
returned to the dealer or manufacturer for resealing.

4.7 Charging battery

The battery will be charged when the NANO3 is connected to the external power through a
usb port. It can be charged from a wall adapter, or directly from a PC or from the NANO3
power cable.
If you want to charge faster, then you must connect the NANO3 to a power supply, wait for it
to boot up, then press the rocker button to switch the unit off. In this mode all the NANO3
functions (GPS, Bluetooth, Memory) are turned off, this will increase the charging speed. In
this mode the NANO3 can be fully charged in approximately 5 hours. The LCD screen is still
on, but the backlight is off. It is still possible to monitor the level of charge. The level of
charge is also visible via the LED indicators. More information on charge level and LED
indication in chapter 4.4.

Sometimes it may appear that the NANO3 battery level when connected to a
charger, looks full. When you then disconnect the power, the battery level drops
to 90%. This is normal as the battery level indication is different when the
charger is connected and when it is disconnected. To really fully charge the
Nano3, please continue charging for a few hours. In fast charge this time will be
shorter. Charge current must drop close to 0 or you will see indication FULL.

Version 2.06 February 2017

Page 19 of 44

4.8 Connecting to a computer

Before connecting the NANO3 to a computer, you must turn it off.
Connect it to a computer using the supplied USB cable or any other standard USB-A to mini­USB cable. The NANO3 flight computer will be identified automatically and a new removable
storage device will be indicated. The name of the device will be NANO3_<SERIALNUMBER>.

Open this device to see its content.

Version 2.06 February 2017

Page 20 of 44

In the root folder you will find the flights created by the NANO3 and the NanoConfig
program. The NanoConfig program will run only on Microsoft Windows operating systems.
Double click to run it.

On the first connection of the NANO3 to a computer, it may not be recognized
immediately. Disconnect the NANO3 from the computer and connect it again in
order for it to be recognized.

4.9 Downloading flights

Turn off the NANO3 and connect it to a computer using a USB cable. Navigate to the root
folder of the NANO3 and use your preferred method of copying files.

Flights are stored in files with the IGC standard filename. If you find it difficult to decode this
standard, we recommended that you switch to detailed view to see the date of the file.
In detailed view, the file date and time shows the landing time of the glider.

Flights can also be downloaded using the NanoConfig for Android devices. More details are in
Ch.7.4.

4.10 Bluetooth pairing

In order to connect to the NANO3 via Bluetooth you have to search on a PDA for Bluetooth
enabled devices in range. (See chapter 7.2.2.5 to enable Bluetooth) The NANO3 will be
identified as LXNAV-NANO3-<SERIALNUMBER>. Click PAIR or CONNECT to connect to the
NANO3. A security pin must be entered. The pin code for the NANO3 is 1234 and cannot be
changed.

4.11 Storing Nano

The NANO3 must be stored in a dry environment with temperature lower than 25°C (77° F).
If the NANO3 will not be used for an extended time, it is recommended that you charge the
battery to 50% beforehand.

Version 2.06 February 2017

Page 21 of 44

The NANO3 and the BATTERY have protection circuits which protect the battery from being
overcharged or overly discharged. If the NANO3 is stored with an empty or near empty
battery, eventually the battery will be discharged so far that it will not be possible to charge
it again.

Version 2.06 February 2017

Flarm

Waypoint

Task

Setup

5.2 Main navigation screen description

The main navigation screen consists of a map with coloured airspace, waypoints with names
or task (depends on which page you are looking at), vario tape on the left and status bar on
the top. The vario tape and vario dynamics can be configured in the Setup-Hardware-Vario
menu. If you don’t want to see the vario tape, you can switch it off. The status line indicates
the status of the GPS, indicates the chosen waypoint that you are navigating to, the status of
the Bluetooth device and the battery level. Menu buttons appears, when you press any one
of the buttons. Each button has its own function which is described on the button label. The
functions of buttons are mostly related to the page where you are (waypoint, task, flarm,
info, setup). If there is no label on the button, this button has no function.
Battery level can be displayed in two ways, with the classic battery level indicator or round
progress with number inside, which indicates remaining hours. Outside progress indicates
percent of the battery level. When the remaining time is calculated to be less than 1 hour,
the indication becomes red and the inside number means remaining minutes, the outer ring
is progress for last hour (60 minutes).

Classic battery indication

Indication of battery with

remaining time

Indication of charge levef,

when battery is charging

When the battery is charging the indication is as follows:. Inside symbol indicate charging,
outer ring is percent of charge.
The accuracy of battery life measurement depends on how accurate the battery capacity has
been measured More about battery calibration can be read in chapter:4.4. In the centre top
of the map is the “off course” indicator, which helps the pilot fly in the right direction. At the
bottom of the map screen are three nav boxes, showing bearing, distance to the target and
the pressure altitude.

5.7 Setup Menu

5.7.1 QNH

Under this page, the pilot can change the QNH setting. If QNH setting is correct, Nano3 will
show correct altitude.

Wrong QNH setting will have effect only on wrong altitude warnings. QNH setting
has no influence over the recorded altitude in the IGC file

5.7.2 Flight recorder

Under this page; flight recorder, pilot information and glider data are configured.

 Recording interval sets the interval when the GPS position will be stored in flight
 Auto Finish will allow the automatic finish of the flight, under certain conditions.

Uncheck this item for wave flying. (ground speed is used to indicate the end of a
flight and in wave it is possible to be stationary or even fly backwards in relation to
the ground)

 Auto Off will power off the NANO

3

30 minutes after the flight is finished

 Logger always on will force the logging/write position to an IGC file immediately

after power on. Normally the NANO3 logger is triggered by ground speed exceeded
40km/h or vario over 1m/s. This function is recommended to be enabled only for
hang gliders.

 Pilot name must be entered here
 Co-Pilot name must be entered here, if glider is doubleseater.
 Competition sign of glider
 Registration of glider
 Glider type
 Glider class

Task, Flarm, Theme setting and NavBox customization.

Version 2.06 February 2017

Page 27 of 44

5.7.5 Warnings

altitude warnings, flarm warnings and their conditions can be setup under this menu.

The flarm warnings are classified into three levels (See Flarm manual for details on
www.flarm.com)

 First level (Low) approximately 18 seconds before predicted collision
 Second level (Important) approximately 13 seconds before predicted collision
 Third level (Urgent) approximately 8 seconds before predicted collision.

5.7.6 Obs. Zones

This menu defines the default observation zone geometry. The following items can be
chosen: start zone, turn point zone and finish zone.

Each type of observation zone is defined with two angles, two radii and mean bearing
(Angle12). These parameters enable the creation of any known zone geometry separately
for start, turn point and finish.

Using parameters in the zone dialogue it is possible to describe all types of observation
zones. Angle12 defines the orientation of the observation zone. Available values for
Direction are:

 Symmetric: This is the most common selection for turn point.
 Fixed: This is mostly used for assigned areas.
 Next: will orient the observation zone in direction of the outgoing leg. This is usually

used for start.

 Prev: will orient the zone in direction of the incoming leg and is usually used for the

finish.

Version 2.06 February 2017

Page 28 of 44

 Start: orientates the sector always towards the start.

If the Line checkbox is checked the sector will become a line type of observation zone. The
Radius 1 parameter describes half of width of line length. Use the UP/DOWN arrow buttons
to increase or decrease radius for step 0.1. Long press will increase/decrease for 5.0.
If Line is not checked the Angle1 parameter will define the basic shape of the observation
zone. A value of 180° means that the zone is a cylinder and 45° is the classical FAI sector.
Use Up/Down buttons to select right angle.
Angle2 and Radius2 are used for more complex observation zone setups.
When changing observation zone parameters the screen is automatically updated to display
the new zone.

5.7.7 Hardware

In the Hardware menu there are four sub items:

5.7.7.1 Flarm

If a flarm is detected, the user can make some configuration setting changes on the flarm
and get some flarm status information .

5.7.7.2 Vario

Version 2.06 February 2017

Page 29 of 44

Vario submenu allows you to adjust the Vario filters for the Vario needle and the vario

sound, the time constant for average vario and vario tape range.

5.7.7.3 Communication

In the communication menu, you can enable or disable the Bluetooth device, enable or
disable NMEA output on the USB port, baudrate for external serial interface.
Communication enables you to set the way NANO3 will communicate with the Flarm. With
Target data NMEA you can enable NMEA data reception (GPRMB and LXVTARG) from other
external GPS devices (Oudie, GPS loggers,..). Target data source enables the NANO3 to
communicate all information about the current target, depending on which page you are
(Task or Waypoint). AUTO option automatically detects the page mode (whether you are in
Task or Waypoint page) and send information about your current target.

5.7.7.4 ENL

This page is just for monitoring the engine noise level.

5.7.7.5 Sounds
In this menu various setting for sounds can be adjusted. Volume of vario sound, enabling of

system sounds and enabling of vario sounds. From version 1.5 here is also sound setting

for Flarm warning.

Vario volume can also be adjusted using rocker button, but only in GPS info page.

Page 30 of 44

5.7.8 Files

Airspace and waypoints files can be selected here. The NANO3 supports CUP file format

for waypoints and CUB file format for airspace. There is no limitation in file size or number
of waypoints, but reducing the size of the airspace area or number of waypoints,
performance of the NANO3 will be better.

In the same section you can convert all IGC files loaded on the NANO3 to KML file format.
FlarmNet data can be loaded also in this section and is useful only if flarm is connected to
NANO3

5.7.9 Units

In this menu can be set the units for speeds, distances, altitudes…

5.7.10 Logbook

All flights recorded by the NANO3 are stored and sorted by date here. The user can find date,
take-off and landing time and duration of the flight. Use the two middle buttons to navigate
through the list. Long press of these buttons will get you faster to the first or last flight
recorded.

Version 2.06 February 2017

Page 31 of 44

5.7.11 Polar & Glider

The Polar and Glider section allows you to load and edit a set of parameters for your glider’s

polar. You can select from a pre-defined list of nearly every common glider or make your
own polar.

Select a Glider from the List: presents you with an alphabetical list of all the common
gliders and associated polar data. All glider data will be copied from the chosen polar.

You can modify the polar by changing coefficients a, b and c. A polar is defined as a
quadratic equation with the parameters a, b, and c.
Use the SeeYou program (Tools->Polar) to calculate coefficients a, b and c for a given
glider’s polar. The program requires three sink points entered at selected speeds (e.g.: 100
km/h, 130 km/h, and 150 km/h). The program will calculate the values of a, b and c, which
should be noted and entered into the NANO3.

 Class: Options for Touring, Ultralight, World, Twin-seater, Club, 18-meter, 15-meter,

Open, Standard and Unknown are available.

 A, b, c: Options can be adjusted or entered for a non-listed glider.
 Reference load (wing loading) value represents the value at which the polar was

measured.

 Reference weight corresponds to the weight value at which the polar was

measured.

 Maximum takeoff weight is the maximum take-off weight allowed for the glider.

It is not used in the calculation; it is just a reminder to the pilot of the maximum
take-off weight. Empty weight is weight of the glider without the pilot and ballast.

 Pilot weight is the weight of the pilot with parachute and baggage.
 Co Pilot Weight is the weight of the co-pilot with parachute and baggage.

5.7.12 Wind

In this section the user can define wind calculation method. Select Manual to adjust
manually wind speed and wind course. In automatic mode, this will be done automatically
by the NANO3 based on GPS data.

Flight declarations can be uploaded to the NANO3 in four different ways:

 Directly on the NANO

3

 Using the NanoConfig program on PC,
 Bluetooth (NanoConfig for Android, Oudie, XCSoar,..)
 Serial interface (PDAs, Oudie, XCSoar)

Declarations are stored in the SYSTEM folder in a file called decl. The declaration file is
formatted as a standard IGC header file. It is recommended that you do not try to modify
this file yourself.

7.1 Directly On NANO

3

7.1.1 Pilot information

Detailed information is written in Ch.5.7.1

7.1.2 Declaration and editing of a task

In the Task page, the user can enter or edit the task, which will then be automatically
declared when you leave this page. Waypoints can be loaded into a task from the active
waypoint file.

A Task can be entered in a very simple way. In the task page you can press the edit button.
Using the up or down button you can highlight an existing waypoint or empty space and
then set a new waypoint. By pressing the Ins. (insert) button you can start browsing
through all of the waypoints in the selected CUP file.
Selecting from a list of waypoints is very intuitive. The NANO3 will only offer you a choice of
characters that are available from the list of waypoint names available. Using the button >>
you can move to the next character (right), the red part of the label B indicates one space
back or one character to the left uning a longer press of the button. A similar function for the
OK button, where you can confirm a selected waypoint or with the C, you can cancel the
selection of a waypoint. The previous waypoint will then be selected.

When you are back in the Task menu, you can Insert or delete D a waypoint.

Version 2.06 February 2017

Page 36 of 44

To

insert

a waypoint you make a quick press on the Ins. and to

delete

a

waypoint you press and hold down D for about (not more than) a second

Each waypoint can have a custom zone or area applied. These areas can be modified by
pressing to Zone button.

7.2 On a PC with NanoConfig for Windows

Use the NanoConfig program to configure the NANO3. A flight declaration can be uploaded or
various parameters can be modified using this program. The NanoConfig program consists of
two major screens. A flight declaration screen and a settings screen.

You may toggle between these two screens by pressing the Declaration or Settings
button in the upper left corner of the NanoConfig program.
Press the OK button to confirm changes and exit from the program. Press Cancel to
abandon changes and exit without saving data.

It is important to run the NanoConfig program directly from the NANO3. Do not
copy the NanoConfig program to another location as the settings and declarations
will not be written properly to the NANO3.

Version 2.06 February 2017

Page 37 of 44

The version of the program is written in the lower left corner of the NanoConfig window.
When requesting support from LXNAV or reporting a bug, please always include the version
of the program in your email.

All NANO3 configuration variables are stored in the SYSTEM folder of the NANO3 in
a file named “system.ini”. It is strongly recommended that you do not modify this
file yourself. If you need more information about the “system.ini” file please
contact us.

7.2.1 Using the Nanoconfig program

Run the NanoConfig program and go to the declaration screen. The declaration screen is
split into two groups. Pilot and glider related information is in the top group and the task
declaration is shown in the bottom group.

7.2.1.1 Pilot information

Enter pilot and glider information in the pilot section. In the top right you will find two icons.
The first icon will show a list of stored pilot information and the second will add the current
pilot information to the list.

7.2.1.2 Task declaration

Before creating a task you have to load the waypoints from which the task will be created.
Press the Load Waypoints button to load waypoints. Waypoints can be loaded from a CUP
formatted file. Once waypoints are loaded you can create a task by typing the names of the
waypoints. Use the icons in the upper left corner of the task declaration group to add or

Version 2.06 February 2017

Page 38 of 44

delete a point or to clear the whole task. Task points can also be deleted by pressing the
DEL key or can be inserted by pressing the INS key.

7.2.2 Changing parameters with NanoConfig

Run the NanoConfig program and go to the settings screen. The settings screen is split into
two sections. Settings dedicated to the NANO3 and settings for NanoConfig.

Parameters for the NANO3include recording interval, NMEA output and Bluetooth enable
settings.
In NanoConfig you can change the distance units used in the task declaration and the format
of latitude and longitude.

7.2.2.1 Flight recording interval

The flight recording interval is set to one second by default. It is recommended that you
keep this setting. Even with the recording interval set to one second, the NANO3is capable of
storing approximately 28000hours of flight. Having a recording interval of one second will
allow you to do more accurate post-flight analysis and increases the probability of obtaining
a data point in the observation zone.

If you wish to change these settings, use the up/down arrow or type a new value.

7.2.2.2 Automatically finish flight

If this option is enabled, the flight will be automatically finished and digitally signed once
conditions for finishing the flight are met. The NANO3 must fulfil the following conditions for
30 seconds. GPS status is ok, ground speed is below 4m/s, vertical speed is within 0.2m/s
and altitude is below 3000m.

7.2.2.3 Start recording on power on

If this option is enabled, recording of a new flight will be automatically started when the
NANO3 is powered on. If this option is disabled the NANO3 will start recording when vertical
speed is above 1m/s and the ground speed is above 8m/s. This option is most useful for
hanggliders.

Version 2.06 February 2017

Page 39 of 44

When this option is enabled, option Automatically finish flight is ignored.

7.2.2.4 Automatically turn off Nano, when flight is finished

This option is very useful for NANO3 when installed more or less permanently into the glider.
If this option is enabled, the NANO3 will automatically switch off 30 minutes after the flight is
finished.

7.2.2.5 Bluetooth

Check the Enable Bluetooth checkbox if you want to turn it on. By default Bluetooth is
disabled.

When Bluetooth is enabled, the NANO3 will consume more power and the total
endurance of a new and charged battery will reduce approximately to 16 hours.
Without Bluetooth enabled NANO3 can run up to 35 hours.

7.2.2.6 NMEA output

Check Enable NMEA output to output NMEA data. The NANO3 will transmit the following
NMEA sentences GPGGA; GPRMC, LXWP0 every second and LXWP1 once per minute.
NMEA can be output to either the serial interface or Bluetooth but not to both
simultaneously.
Change the NMEA baud rate, if you want to output NMEA at different baud rates.

7.3 Using Bluetooth or serial interface

Flight declarations can also be uploaded using the serial interface or Bluetooth (See chapter

7.4.1 for Bluetooth pairing). The NANO3 must be running in normal operating mode.

When connecting through the serial interface, you should use the same baud rate
as is set for NMEA output on the NANO3.
When connected through Bluetooth baud rates are not important.

Please refer to the manual for the software used to upload flight declarations. (E.g. SeeYou
Mobile)

Version 2.06 February 2017

If the NANO3 is turned on and BlueTooth functionality in the NANO3 is enabled, it will appear
on the scanned list. Choose nano. The first time it will be necessary to pair the NANO3 and
the Smart Phone together. More about pairing in Ch.4.9.

7.4.2 Main page

On the main tab, information about the NANO3 and its GPS status.

7.4.3 Downloading flights

The first time you access this tab, NanoConfig will automatically start reading flights from the
connected NANO3. Downloading always starts from the most recent to the oldest flight. If
you have a lot of flights in the NANO3’s memory, the transfer of the logbook can be
interrupted with the BACK button.

Version 2.06 February 2017

Page 41 of 44

After downloading of the logbook data is finished, a short press on the desired flight will
start the download process. If the flight size is big, the download may take more than
minute. Flights are downloaded into the NanoConfig folder. With a long press on the flight,
the downloaded flight can be shared with other applications installed on your smart phone
(Gmail, SeeYou, OLC (not available) , Google Docs, Facebook).

7.4.4 Editing pilot info

The Pilot tab can be used to edit information about the glider and crew.
