0.4.0b11

Downloads

• Android
• Mac
• Windows
• iOS (TestFlight link)
• Ground station (already included in the OpenHD images)

Changes

• Fix upper/lower bars
• Replace heading widget with more efficient code
• Ladder tweaks
• Horizon bar tweaks
• Add detailed Mavlink telemetry stats in the lower right of the status panel
  • Use them to see if you are missing some telemetry messages, they should all be changing constantly
• Automatically enable Mavlink telemetry messages on Ardupilot flight controllers (may work on PX4 as well)
  • You no longer need to edit Ardupilot's SRx_EXTRA parameters
• Add a simpler speed widget (for Norbert)
  • Note: this widget doesn't have settings in the settings file at the moment, will be added in the next release
• Add settings file support on ground, Android, Windows, Mac, Linux (iOS is coming soon)
  • On the ground, the new /boot/qopenhd.conf file allows control over everything, just edit the file and reboot
  • On other platforms you can use the new Manage tab in the settings area to save or restore the settings from a file
  • If you load a settings file on mobile/desktop platforms you must restart the app. On Android the app will do it for you.
  • You can use the same file on any platform
  • Note that the file is not just widget layout, but all settings. We will make it possible to export/import widget layouts so you can share them with other people soon.
  • The file is self-updating. If we add new settings, you don't have to manually keep it up-to-date. On the ground this is entirely automatic, on other platforms just load and save the settings file again.

Known issues

• Air-side power stats may not be arriving (OpenHD image issue, doesn't require a fix in QOpenHD)
• The charts are disabled while we hunt for a bug
• App can be started more than once on Windows/Linux (#61)
  • This is unintentional and will be fixed soon
• GPIO user interface is temporary, will be replaced soon with something nicer on the main OSD screen, support custom names and possibly custom icons
  • Keep in mind that the GPIO numbering is based on the processor GPIO numbers, not pin numbers
  • GPIO5 means BCM5, not pin 5, if you need a good reference for the GPIO numbers, see https://pinout.xyz/

0.4.0b9-1

Raspberry pi only release, use 0.4.0b9

0.4.0b9

Downloads

• Android
• Mac
• Windows
• iOS (TestFlight link)
• Ground station (already included in the OpenHD images)

Note: the downloads below include a hotfix for iNav/Betaflight flight modes. The change is trivial but the impact of leaving it out would be significant, so it's included even though it technically makes the downloads 0.4.0b9+1 rather than 0.4.0b9.

Changes

• Fix clickthrough from settings panel to OSD widgets
• Fix RC RSSI using Mavlink1 messages
• Fix uplink RSSI widget cutting off the right side
• Fix Betaflight Mavlink messages being dropped
  • They use an odd Mavlink component ID instead of the standard 1:1 sysid/compid pair
• Fix LTM battery usage display
• Fix LTM RSSI for external RC
• Fix PX4 flight modes
• Replace Android video renderer
  • Now using a standard video rendering system on every platform, which will allow us to do things like realtime stabilization, 360/VR and object tracking
• Replace video networking code
  • Should not be affected by CPU use as much as the older networking code was, and should also use less CPU time itself
• Reset hardware decoders when video config changes
• Add power control/status panel
  • Allows remote remote/shutdown of ground and air
  • Allows viewing ground/air power voltage and current if a sensor or power board is connected
    • INA219 and Lifepowered Pi boards supported, connect them to the I2C pins and they should just work
  • We have an OSD widget for the ground power details for AIO builds, so you can keep track of their internal battery level
• Replace Glow with text outlines, should be higher contrast and reduce CPU use
• Replace several of the complex widgets with more efficient c++ code
  • Reduces CPU use
• Move flight controller temp widget under uplink by default
• Update sidebar layout
• Add missing warning watermarks on video surfaces
  • Can be disabled in the settings area

Known issues

• The charts are disabled while we hunt for a bug
• App can be started more than once on Windows/Linux (#61)
  • This is unintentional and will be fixed soon
• GPIO user interface is temporary, will be replaced soon with something nicer on the main OSD screen, support custom names and possibly custom icons

0.4.0b8

Downloads

• Android
• Mac
• Windows
• iOS (TestFlight link)
• Ground station (already included in the OpenHD images)

Changes

• Fix RC RSSI calculation
• Update the uplink/downlink widget sizes so they match (#135)
• Replace h264 parser
  • The older code had loads of problems and has been causing crashes on iOS
  • This was the reason we hadn't moved Android over to native video decoding yet
• Enable native video decoding on Android (#57)
  • GStreamer is no longer being used on Android at all, instead we are directly parsing the video stream and feeding the data into the hardware decoder
  • This should work on every phone, however some of them may need some minor changes to ensure they don't add unnecessary latency (some hardware decoders take the "safe route" and delay video frames when they don't really need to)
  • Note: we are also going to replace the Android video renderer I wrote back in February, because it isn't efficient enough
    • The new one is part of Qt rather than something custom, so we don't have to write anything new
    • That change is not included yet, so if you still see any video or performance issues that will be why
• Handle RTP FU_A partial packet loss
• Fix app setting row width (#124)
  • Qt bug made the rows unaware they should have expanded to fill the horizontal area
• Restart video on iOS after being in background (#123)
• Fix drone orientation lock switch (#136)
• Internal changes
  • Add hardware accelerated stereo OSD mode using OpenGL shaders (#103)
    • This does not have a button to enable it yet because we need to adjust some of the widget sizes for the smaller area

Known issues

• The charts are disabled while we hunt for a bug
• App can be started more than once on Windows/Linux (#61)

• For Windows download the exe file
• For iOS use this link to join the TestFlight beta
  • Note that Apple has not approved this update yet, but it should be available in a few days
• For running on the OpenHD ground station, use the release images of OpenHD

Test notes

• We have reports of video stuttering or freezing on Android with the v0.4.0 beta series, test very carefully on the ground
  • The video issues are caused by GStreamer using so much CPU time on Android, it won't be there much longer
• iOS has native video decoding and OpenGL rendering enabled now, which should significantly improve battery life and prevent video problems, but it may require some fixes for RTP and additional testing on specific devices
  • There are a few crashes related to this showing up in the Apple developer portal, the video system is being updated to prevent that from happening anymore
• There are new widgets in this release, and some of them have not been optimized for performance yet
  • We will be optimizing these very soon

• Add flight controller temperature widget
  • Date comes from Mavlink
  • May only work on Ardupilot, iNav may not send that telemetry message
• Fix message HUD log levels
  • They're supposed to match the Mavlink log levels, which are the same ones we use on the ground/air for system status messages
• Show status messages from ground/air on the message HUD
  • Ground station USB video saving will now show start/progress/finish both on the ground station screen and remotely on Android
• Fix downlink settings/detail panel being too long on small screens
• Don't flash / make bitrate icon red if bitrate set manually in OpenHD
• Fix font sizes on preset panel text
• Translations
  • We have German, Russian, Dutch, French, and Spanish translations for the entire interface

Changes

• Prevent screen lock on iOS (#122)
• Fix total distance widget
• Add setting for showing lat/lon all the time
• Fix home position (#118)
  • This sets the home position based on HDOP and several good readings before the drone is armed
  • Once the drone is armed it is assumed that the last position is home
  • If the telemetry stream coming from the flight controller supplies home position data it will be used instead
• Fix total mAh widget icon
