This manual covers BLU device in combination with its Kanja Android app. BLU is the interface device which plugs into Kanardia CAN bus network. It listens to the CAN bus traffic and transmits the traffic to the Kanja app via Bluetooth connection.
Kanja can be installed from Play Store. Example is shown on Figure 2: 1. Open the Play Store app on your Android device. 2. Enter Kanja Kanardia into the search field. 3. Locate the Kanja app and install it in a standard way.
However, the system will ask you for more permissions. Please allow access to them otherwise you will not be able to pair it with BLU. It is beyond our knowledge why all these permissions are needed.
A click on the Scan button opens a list of detected Bluetooth devices. Normaly you have to do this only once – to pair your BLU with Android. Status bar is briefly shown on the app start. Once the latest data has been downloaded, Done is displayed and shortly after the line disappears.
Unfortunately, many Androids have problem in detecting names of the devices, so only their addresses may be shown. You got you BLU address listed on the Warranty papers. If Kanardia BLU does not appear on the list, compare the addresses with the address on the Warranty paper.
Figure 5: First connection process. Number of detected Bluetooth devices can be significant. Pairing request number is random. 1. Plug BLU into a free CAN slot and make sure you have at least one terminator in the network. 2. Make sure the CAN network is on. BLU shall be blinking.
BLU & Kanja — Manual 5. Standard Options Figure 6: An example of devices detected on the CAN bus network. Blue arrow closes this page and switches back to the previous one. Al- ways use this command to get previous page. Do not use Android back.
BLU & Kanja — Manual 5.2 Update illustrates and example. Figure 8: Device general information page. Unit shows the device name. Hardware shows the device hardware version. This shall never change. Software shows the software version as major.minor release. This changes with each update.
In case the application could not successfully update the device (device not working properly) shortly disconnect the power from Kanardia CAN net- work/device and connect it back. Once you will reconnect Kanja with Kanar- dia BLU the application will automatically start processing the problematic unit. Console The Console option may come handy during some troubleshooting and de- bugging.
BLU & Kanja — Manual 5.4 ICan Figure 10: A console page example. Device specific information and diagnostic messages appear on the page. ICan The ICan is also a debugging and troubleshooting tool. It opens a new page which shows all flight and engine messages sent by this device on the CAN bus.
BLU & Kanja — Manual 5.5 Reset Reset The Reset options sends the reset command to the device. Device shall restart as it was turned off and back on. Not all devices accept this command. This command shall be seldom used.
(without fuel level sensors) is used with Digi, there is no way to enter the initial fuel level value as Digi has no input capability. However, when Blu is connected, then the fuel level can be adjusted using this feature. The fuel level is typically set before flight, but it can be set during the flight as well.
BLU & Kanja — Manual 7. Daqu Options Figure 14: The about and credits window. Daqu Options When selecting Daqu from list of connected devices, the extra options are available as on shown on Figure 15. They are explained in next subsections.
BLU & Kanja — Manual 7.1 Channels When Channels option is selected, Kanja lists names of all detected channels together with their current function and sensor name. An example is shown on Figure 16. Figure 16: Illustration Daqu channels screen. Some channels are not used and some channels are not visible.

BLU & Kanja — Manual 7.1 Channels Figure 17: An example of fuel pressure sensor configuration. 1. The Function lists all possible functions for given channel. For this example, search for the Fuel pressure and select it. 2. The Sensor lists all possible sensors that can be connected to this chan- nel.
BLU & Kanja — Manual 7.2 Offset 7.1.2 Fuel Level Example Fuel level example is similar to one above. Here we assume that a resistive sensor with range between 3 and 180 Ohm is connected to the E01 channel. Again, your case may be significantly different: a different sensor may be used, connected to a different channel.
BLU & Kanja — Manual 7.3 Reset Channels Following offset values can be edited: Fuel pressure – adjust the sensor to show zero, when the sensor is not loaded. In some cases, Rotax iS, for example, the sensor must be re- moved and the ECU off.
BLU & Kanja — Manual 7.4 Tank Tank The goal of the fuel level (tank) calibration is to convert the sensor readings (which are in Ohms for resistive sensors or in voltages for active sensors) into fuel volume. Fuel volume must be always given in liters! Before a calibration can be started, make sure that: ...

The bottom part lists volume-sensor pairs. It is important that the sensor value is alive. Its value must change logically if the fuel level changes.
BLU & Kanja — Manual 7.4 Tank Clear All This command will remove all volume-sensor pairs from the list. You may start with it, if you want to calibrate tank from scratch. Beware the command does not ask for a confirmation.
BLU & Kanja — Manual 7.4 Tank Figure 24: Deleting a measurement point from the list. 7.4.3 Verification With ICan Fuel level indication can be verified with the ICan option. Once Tank page was closed tank settings were stored permanently in Daqu (miniDaqu). If all is correct, Daqu will start transmitting fuel level CAN messages on the bus.

BLU & Kanja — Manual 7.4 Tank value shows the raw sensor reading in Ohms for the resistance based sensors or voltage for active fuel level sensors (capacitive, or pressure based). Note: Usually, you have to put some fuel before the fuel reaches the bottom of the sensor and the sensor starts reacting.
BLU & Kanja — Manual 8. Indu & Digi Options Figure 27: Shape of the calibrated tank. Figure 28: Notes taken during tank calibration example. Indu & Digi Options When selecting Indu or Digi from list of connected devices, the extra op- tions are available as on shown on Figure 29.

If you use a set of several Indu instruments, it is not always obvious who stores the engine time information. This may not be the RPM, but it may be the Altimeter or a Combo instead. Please contact support@kanardia.eu if unsure.

BLU & Kanja — Manual 8.7 Response Figure 33: Flag values depend on different circumstances and also on other instruments connected to the same CAN bus. This option allows you to change a time constant of a low pass filter for some frequently used parameters.
BLU & Kanja — Manual 8.8 Offset Figure 35: Time constant for vertical speed (Vario). Offset This option is useful only for Indu instruments with built-in static and/or dynamic pressure, like master altimeter, master airspeed indicator or combo. It allows sensor offset of static or dynamic pressure. Electronic sensors may drift a bit over longer period of time and here we can adjust their offset.
BLU & Kanja — Manual 8.9 Password Figure 36: Example of static pressure offset. Figure 37: Change the offset until the sensor shows zero. Password This is special option which allows access to a couple of rescue commands. Don’t use it unless we ask you to do so.
