XCSoar Menu with LK8000 lancher

This is modified version of the XCSoar menu that is able to launch also LK8000. If LK8000 is detected on the system an additional button in added on the bottom bar.


Instruction  :

  • Install Lk8000 and XCSoar ( order not important )
  • Install this menu

If you have to update LK8000 or XCSoar you will have to reinstall also this menu

Kobo and Bluetooth module RN42

RN42 4 is a more reliable Bluetooth module that HC05. Unfortunately, it’s more expensive that HC05 but can be found on the market at about 15-20€ (HC05 is a 5€ module). https://goo.gl/hUXjvV


Only 4 pins are required on the RN42  ( TX,RX,Vcc and GND)



Use terraterm : http://ttssh2.osdn.jp/index.html.en for connection unsing the following settings :

    Baud:  115,200 (use 9600 if jumper 4 is set)
    Data Bits: 8
    Parity: None
    Stop Bits: 1
    Flow Control: None


Send command :


The RN42 should reply with : "CMD"confirming the device is in command mode

#sets the serialized friendly name of the device

#sets the security pin code

# set authentication Pin code

#sets the mode  Pairing Mode.

Now switch on the Digifly AIR BT and put it into Airtool BT mode. ( see Digifly documentation on section 13.2.2 ). Make sure no other Bluetooth devices are in the area.

#Device Scan Inquiry,

Done . Now connect the RN42 to your KOBO







LK8000 LiveTrack24 Radar


Latest release of this LK8000 test version can be found on this Facebook groop : https://www.facebook.com/groups/avionicavololibero/1697416603912087/

This is not a complete installation of LK8000 but only a small patch. LK8000 V6.0 is required on your system prior to installation.


To enable Livetrack24 Radar you need to set two parameters in the option menu :

In "Pilot configuration" set Enable Radar "ON"

Leave "Live tracker log interval" to 0 unless you want to use LK8000 also for sending your position to the configured server.

 Then go to menu 13 - "Map Overlays" and activate "Flarm n Map"

Provide an internet connection to your Kobo.

If you are running on a Kobo you will need to provide a hotspot with internet connection to your Kobo. Best solution is to use your mobile phone. First of all, use the Kobo e-reader software (use the KOBO button o Nikkel to launch it) to pair with your Wi-Fi and provide the connection password. This has to be done only once. As L8000 start ( in Simulation or Fly mode ) it will enable the Wi-Fi and connect automatically with your hotspot.

Launch LK8000

As soon as LK8000 detect a live friend (only your Livetrack24 friends will be visible) a message "Flarm detected - Livetrack24” will appear on the screen:

 Your fiend will appear on the map with a coloured arrow. The colour indicates its vertical speed. Same colors of the vario bar.

Beside the arrow, if your friend is lifting, a vertical velocity label ( in m/s) will appear.

If the Livetrack24 signal will be lost for more that 60 seconds your friend will become a "GHOST" and the symbol on the map will change to a small square:

After 2 minutes  of lost signal your friend will become a “ZOMBIE” and disappear from the map.


If some friends are live an additional Radar Map will be available. Switch to that map tapping on the left or right part of the screen.

In this map you will have an horizzontal and vertical view of your frieds


One of the main feature in LK8000 is multitarget : http://www.lk8000.it/new-20-features/multi-targets.html

Tapping on the centre of the "Bottom Bar" you can switch to several configured pages and, if Flarm is detected, an additional page ( 4.1 ) will be available.


In that page you will have a list of all your friends live. To lock and target a friends select it (tapping on the upper part of the screen to scroll up and to the bottom part to scroll down) and then make a long tap to the centre. A new menu will appear with a button “Target”. Click it. Now your friend will be target.

In that way you will have an additional 4.3 page with complete information on your friend

Switching back to the map (tap on the centre on the Bottom Bar) you will see your friend locked and all information on the overlay (distance, bearing, etc.) will refer to your friend


You can then use the fantastic Multitarget feature in LK8000 to easily switch from different targets  (task,Alternates,Landings, etc. ) tapping on the upper-left corner.



Digifly AIR BT wireless connected with KOBO


Needed components





And obviously a KOBO (mini, glo , HD, etc) and a Digifly AIR BT

Needed tools

  • electronic welder


Weld the HC-05 module


Weld 5 wires to the HC-05 module as indicated in figure.  Connections are :

TX – UART transmission

RX- UART reception

Vcc – 3.3v

GND – Ground

KEY-34 – When set to 3.3v modules accept AT configuration commands. This is needed only during the configuration phase with USB-TLL component and can be removed later.


Configure the HC-05 module using the USB to TTL converter


Put the TTL converter Jumper to 3.3v and connect it to the  HC-05 as follow :



Connection are :














Connect the USB-TTL to your computer. Windows will automatically install the needed drivers.

Start Termite and set the connection parameter as 38400 , 8N1

Send the following commands ( in red, green a comments ) to the HC-05 :

AT                                        # Should replay OK

AT+ORGL                            # Reset to origin settings

AT+NAME=KOBO            # Set name as you want

AT+RMAAD                       # will release the module from any previous PAIR.

AT+PSWD=0000               # set password the same as Digily AIR BT

AT+ROLE=1                        # Set HC-05 to act as as master

AT+UART=115200,0,0    # Set port speed

AT+CMODE=1                      # Set HC-05 to connect with the nearest Digily AIR BT

FINISHED. Use the following commands only if you whanto to bind with your AIR BT. No other AIR BT will be able to connect.

Pair you Air BT. Enable Bluthooth on the AIR BT and put it in menu "Airtools"->BT. Power on the HC05 and afther some seconds the AIR BT shoud replay : BT LINK. Done

[ If you want to connect only with YOUR AIR BT use AT+CMODE=0]

AT+CMODE=0                   # Set HC-05 to connect only with YOUR Digily AIR BT

Now switch on the Digifly AIR BT and put it into Airtool BT mode. ( see Digifly documentation on section 13.2.2 ). Make sure no other Bluetooth devices are in the area.

AT+INIT                                # Initialize the SPP Profile library by typing

AT+INQ                                # Start searching inquire surrounding bluetooth devices

Suppose you got :

0013:43:09ECC1               # This is your AIT BT address

AT+BIND=0013,43,09ECC1           # Set address  to bind ( NOTE : substitute “:” with “,” in the address )

AT+LINK=0013,43,09ECC1           # Actually PAIR the 2 devices


Done. Close  Termite . Disconnect the USB-TTL from your PC and remove the  KEY-34 wire from 3.3v. Configuration is done and that PIN is not needed any more unless you wont to configure a different source of telemetry. Reconnect the USB-TTL to the PC. Reopen Termite and connect.

From the Digifly AIR BT menu put the instrument in telemetry FLT1 mode ( see Digifly documentation on section 15.2  ). In few seconds you should see NMEA sentences come into your PC.

Important : Verify your HC-05 firmware revision using the command :


If you got +VERSION:2.0-20100601 your HC05 is buggy and you will not able to receive complete telemetry from the AIR BT. In that case the only choose you have is to put the AIR BT in CAR mode that will work correctly.



At the and your session should look like this :


Now the only thing needed is to finally weld the HC-05 to the KOBO UART
