The battery can be connected to the TP2 jumper on the kobo, this will enable charge and to be able to use both batteries, while its not good practise to connect 2 different capacities of battery together, we have a very small current transfer and this seems to be ok. If this is an issue for you just unplug the kobo main battery and then wire the 5000mah battery direct in.



Step Seven.

Now we proceed onto configuring the Kobo.

LK8000

i	Connect to the AirWhere home page by connecting to its wifi and going to 192.168.4.1..
ii	Click Configure Hardware. Then under ‘Flight Software’ choose ‘XCSoar - Kobo’ and click ‘Submit’. The board will restart..
iii	First you need to install the Kobo software - choose LK8000 or XCSoar and navigate to their respective websites and download what you like to use, there is a dual boot version available if you wish to run both on your kobo to try them both out.
iv	There are several websites regarding this procedure if you search the web for this, however please first update your kobo by wifi or by downloading the kobo desktop software off the kobo website, make sure your kobo is up to date first, without this procedure your kobo may crash. Once you have updated, plug the kobo into the USB on your pc and then it should create a new drive, navigate to ths drive and copy the flight software you have chosen to the directory called .kobo , once this has completed, unplug the kobo and it will restart and install the software for you.
v	Now take your OTG usb lead and plus it into the a usb battery supply, then into the kobo, the remaining plug into the AirWhere unit. the AirWhere screen should start once more and show some information.
vi	LK8000 now requires configuring to let it see the AirWhere unit. If you proceed to the menu system, bottom right menu, config, config, LK8000 setup, Device Setup. Now add these details in the first Device, device A. Name : Generic Port : /dev/ttymcx0 Ext. Sound : On BaudRate : 115200 8bit
vii	Press close.and then a line saying restarting comm ports will come on screen, then detected FLARM, this shows your system is working. When your kobo gets a GPS lock, the T: value on the airwhere board will start increasing, this shows your system is sending out your location.
viii	Press the middle of the bottom info bar and the FLARM screens will come up, check the airwhere video sections for usage. Hint - to see traffic on the main map, go to ‘config’ and on page 13 at the bottom ‘enable traffic’.

XCSoar

i	Connect to the AirWhere home page by connecting to its wifi and going to 192.168.4.1..
ii	Click Configure Hardware. Then under ‘Flight Software’ choose ‘XCSoar - Kobo’ and under ‘Connection mode’ click ‘Submit’. The board will restart..
iii	Load XCSoar.
iv	Double click on the plane icon at the bottom and bring up the menu. Click ‘Config’ and click.
iv	Edit Device A:- Port : /dev/ttymcx0 Baud Rate : 115200 Driver : Generic.
iv	XCsoar should now be picking up data and a gpslock, T: numbers should be increasing on the AirWhere board and thats it!

Step Eight (Optional).

One of the main things thats missing from the Kobo is sounds, we can now, for the price of a piezo buzzer very simply add these.

7.1	Purchase a piezo buzzer - we do have a really good buzzer available, contact us, however any will do, but you might want to get a decent one to increase the volume. We will have more info regarding this aswell soon, please check back
7.2	Make sure the kobo and the esp32 board are unplugged and away from the battery pack.
7.3	Attach the piezo to the esp32 by connecting the black wire to the pin on the AirWhere board marked GND, one of the outer pins on the board and then the red wire to the pin marked 32.
7.4	Power the Kobo up once more and plug the AirWhere module in. when you now perform actions on LK8000 there should be sounds coming out of the buzzer!

Step Nine (Optional).

 

i	First purchase a GY-86 board, these shouldnt be too expensive, we have them on the shop site if your finding it difficult to find - also make sure you have a speaker attached - we need sounds for the vario ;)
ii	Add a small piece of black tape or neoprene to the top of the tiny pressure sensor on top of the gy86 but be careful not to cover the sensor holes, the pressure sensor is effected by light so we need to keep it in the dark so its stable.
iii	Follow the wiring diagram to setup the vario board. a breadboard can be used to temporarily check the system works ok, however soldering gives a better joint. ESP32 GY-86 board IO12 INTA IO13 SCL IO25 SDA 3V 3V GND GND
iv	To configure LK8000 or XCSoar to use data from this sensor, please change the device driver to be BlueFly Vario we will have our own driver soon but for now please use this, using this driver gives you barometric height and therefore a correct climb visual climbrate, also outside air temperature, this can be setup up in config

The board now needs housing in a case and a way of securing to your flight deck, we do have cases available, so please contact



Please if you do build an AirWhere in this way, as it is so cheap and easy to do please do donate a contribution to the project, the project has taken 2 years and thousands of hours of work to get to here and we have to pay for server fees - many thanks. Our paypal is phil@air-ware.co.uk for any donations to keep this project alive :)




Have fun with the project!
