# My Paragliding Setup



_Last updated: 2023-07-09_



I've got the following devices on my paragliding cockpit since May

2022:



* Display: [ONYX BOOX Poke 3] Android 6-inch e-reader running the

  XCTrack app.

  

  UPDATE May 2023: The 'ONYX BOOX Poke 3' (Android 10; 1072×1448

  pixels = 300 ppi) is discontinued and has been replaced by the [ONYX

  BOOX Poke 4 Lite] (Android 11; 758×1024 pixels = 221 ppi).  Two

  pilots have confirmed that the below instructions work also for the

  'Poke 4 Lite' - they're happy with it.



* Vario: [BlueFlyVario] w/ Bluetooth & GPS v22



* Keyboard: [Recoil Waterproof Bluetooth Media Button]



Everything is attached using industrial-strength velcro. In addition

to this, I carry an Android phone in my pocket that shares internet

with the Poke 3 e-reader for XCTrack live location sharing and 

viewing.



  



I'm fairly happy with this setup. The readability of the e-reader is

excellent - the brighter the sun is, then better it is, and it's

already awesome on cloudy days. The e-reader has a touchscreen, but

since that works so and so with gloves, I use the five-button media

button as an external keyboard. The bluetooth connection between the

Poke 3 e-reader and the BlueFlyVario is 100% reliable and always

automatically. Same with the media button.



The only complaint I have is that one of the two BlueFlyVario has

twice refused to boot up. Unfortunately, when this happens, the _only_

way to get it working again is to reflash the firmware, but that

requires an MS Windows computer, which you probably don't bring on

your flying trip.  This has happend twice to me (August 2022, and

December 2022) - both times during flying trips ¯\\\_(ツ)\_/¯. I hope

that it won't happen again with the newer firmware I now got. OTH,

since it's only out of two identical varios that's been acting up,

there is a slight risk that one is a lemon.



## Procedure on launch



1. Power on the Poke 3



2. On Android phone, start WiFi hotspot



3. Confirm that the Poke 3 is connected to the phone's WiFi



4. Power on the BlueFlyVario vario



5. Start XCTrack



6. Confirm that Bluetooth, GPS and live tracking work



   ![XCTrack status bar with GPS, Bluetooth, live tracking and battery

are all good](images/xctrack-status-bar-ok.png)

   

7. Power on the Media Button and confirm pressing left-right shifts

   XCTrack displays



The only little bit of friction in this set up is the hotspot setup

and making sure the Poke 3 has a wifi connection before launching

XCTrack.  Without that, it's just power on the devices and starting

the XCTrack app.



## Gadget details



### Vario: BlueFlyVario with Bluetooth & GPS v22



I've got the [BlueFlyVario] with Bluetooth & GPS v22.  We ordered two on

2022-05-12 for 348 AUD (~240 USD) and received them 2022-05-29.



* Weight: 48 g



* Dimensions: 58 x 36 x 16 mm



* Battery: ~8 hours (w/ Bluetooth & electromagnetic transducer

  running). 2-3 hours to fully charge.  Observation: A five-hour

  (sic!) flight took it from 100% down to 46% (3.828V; 3 beeps)

  



* Power button: click to turn ON, long press to turn OFF



* Power button when already ON: short press toggles audio ON, BUZZER,

  and OFF. This is easy to press during a flight.



* Battery status (during startup):



  1. First beep is a 1.0s beep at 4000 Hz

  2. Followed by 1-6 "battery" beeps (indicating 3.6-4.2 V)

  3. Followed by a short 0.2s beep at 4000 Hz



* LED lights:



  - BLUE (Bluetooth):

  

      + Flash every second => Bluetooth scanning

      

      + Double flash every second => connected

      

      + Solid => Bluetooth module is disabled (settings

        `SecondsBluetoothWait`).  Fix by restarting vario



  - ORANGE (GPS):

  

      + 1.0s flashing => GPS 3D fix

      

      + off => no GPS fix

      

  - GREEN:

  

      + During startup

      

      + When pressing button

      

      + When lift beep sounds (setting `GreenLED`)



  - RED:

  

      + Charging (turns off if full charged, but may stays on for

        trickle charging)



* Track logs:



  - Capacity: ~60 hours at one-second intervals

  

  - Always on: when GPS has 3D fix (ORANGE flash)



### Display: ONYX BOOX Poke 3 Android 10 e-reader



I ordered the [ONYX BOOX Poke 3] e-reader from BestBuy USA on

2022-05-13 for 190 USD and received it on 2022-05-19.



* Weight: 150 g



* Dimensions: 153 x 107 x 6.8 mm



* Screen: 6.0 inch (90 x 120 mm), 1072 x 1448 px (300 ppi), 16 gray

  scales



* Android: 10



* Google Play Store: yes ([requires manual one-time

  activation](onyx-poke/README.md))



* Speaker: no



* XCTrack: Install and update via [APK](https://xctrack.org/Download.html)

  ([changelog](https://xctrack.org/Change_Log.html))



* Battery: 8-10 hours(?).  Observation: A five-hour (sic!) flight took

  it from from 97% to 50% (running XCTrack in the background and an

  auto-reloading website with live wind data in the foreground)



## Configuration



### Poke 3 and XCTrack



The Poke graphical user interface (GUI) can be a bit peculiar at

first. For example, it uses it's own on-screen keyboard and it also

has a, so called, 'Navigation Ball'.  It's a small round blob that

sits in front on any app you open.  You'll need it.  If you click it,

you'll get access to more action buttons, and one commonly used one is

the "back" button.



In order for XCTrack to go into landscape, which you can set inside

XCTrack by going to 'Preferences' and then 'Orientation', you must

configure the app such that it can override the 'Rotation' settings

that the Poke GUI uses, which is 'Portrait' by default.  To do this:



1. Long press 'XCTrack' app icon

2. Select 'Optimize'

3. Go to the 'Others' tab

4. Disable 'Force to use system orientation' (i.e. set it to OFF)



### Poke 3, BlueFlyVario, and XCTrack



Use BlueFlyVario as an external GPS in XTrack:



1. **Pairing**: In Poke 3 Bluetooth settings, pair BlueFlyVario device

   (e.g. BlueFly-7D0D). No PIN required.



2. **Enable location**: In Poke 3, open the 'Control Center' in the

   Poke 3/Android pulldown menu. There you should see WiFi and

   Bluetooth buttons at the very top.  Below are two panels, both

   showing a set of icons that can be used to toggle settings on and

   off.  The top panel, of these two, has a volume bar and the bottom

   one a brightness bar and a contrast bar.  In the top panel, enable

   'Location' by clicking on the map icon. This icon might be in the

   second "subscreen", which you can get to by swiping left inside the

   panel.  **IMPORTANT**: if this is not done, then you cannot connect

   the BlyFlyVario device in XCTrack (at least not on Poke 3).



3. **External GPS and External Barometer in XCTrack**: In XCTrack, go

   to 'Preferences', then 'Connections & Sensors'.



   a. Under 'Connection', click 'External sensors', select 'Bluetooth

      sensor' and click 'OK'.  It will scan for paired Bluetooh

      devices. Select the BlueFlyVario device (e.g. BlueFly-7D0D).



   b. Under 'GPS', enable 'Use external GPS'.  **IMPORTANT**: If you

      forget this, XCTrack will never recieve GPS data therefore only

      report on the lift and sink (from the barometer in

      BlueFlyVario).  When it works, XCTrack will give the 'GPS

      signal OK' notification and it will show GPS altitute, the

      speed, flight arrow, and more even when on the group.



   c. Under 'Atmospheric pressure sensor', enable 'Use external

      barometer'.  **IMPORTANT**: If you forget this, I think XCTrack

      will use the GPS data, which is much less sensitive, to report

      on lift and sink.



### BlueFlyVario setting



Options to change hardware settings:



* Android: [BlueFlyVario Android App] (installable on Poke 3)

  Download: 

    

* Any operating system: [BFV Desktop Java Application]

  Download: 



For Poke 3, which does not have a speaker, change:



* `UseAudioWhenConnected`: `true` (default `false`)



### Recoil Media Button settings



This device broadcasts itself on Bluetooth as 'PCR-1'. To pair to the

Poke 3, go to the Bluetooth settings and locate 'PCR-1' under

'Available devices'.  Then click on 'PCR-1' to pair it.  When paired

it will appear under 'CONNECTED DEVICES'.  When powered off, it will

be listed under 'PAIRED DEVICES', which are the devices that the Poke

3 remembers.



When powered on, the Poke 3 will immediately connect to the Recoil

Media Button device.



The device goes automatically into a [sleep mode after 20

minutes](recoil/Recoil_PCR-1-UserManual.pdf). This is to preserve

battery. Pressing any button (Previous track, Next track, Volumn Down,

Volume Up, PAUSE/PLAY) will wake it up with very little delay.



To configure what the buttons should do, open XCTrack, go to

'Preferences', andthen 'Key bindings'.  I use the following settings:



* Switch to page left: Previous track

* Switch to page right: Next track

* Zoom map in: None

* Zoom map out: None

* Toggle map panning: Long press: 85

* Pan map LEFT in panning mode: Long press: Previous track

* Pan map RIGHT in panning mode: Long press: Next track

* Pan map UP in panning mode: Volumn Up

* Pan map DOWN in panning mode: Volumn Down

* Show menu: None

* Revert to previous waypoint in task: None

* Advance to previous waypoint in task: None

* Increase display brightness: None

* Decrease display brightness: None
