Changes in 2.0.7

• Fix Ralink RSSI display
• Fix Ralink single USB/IP cameras
• Update QOpenHD to 0.4.0b16
  • Fix ADSB data from SDR devices (Luke Shanks)
  • Fix to ADSB aircraft rotation with map orientation (Luke Shanks)
  • Add error reporting for ADSB issues (Luke Shanks)
  • Optimize the horizon widget (Luke Shanks)
    • Should reduce CPU load and improve video rendering as a result
  • Optimize the FPV widget (Luke Shanks)
  • Add option to limit FPV vertical/lateral limits (Luke Shanks)
  • Add setting for flight controller Mavlink SysID (Luke Shanks)
    • Note: You DO NOT normally need to set or change this, the system will do the right thing by default
  • Add ground station power widget (Jelle Tigchelaar)
    • There will now be 2 power/battery displays on screen, one for the flight controller and one for the ground station
    • They are marked with Air/Gnd
    • If you don't have any ground power sensors attached you can disable the widget in the settings file or settings menu
    • The design of those power widgets is likely to change soon to make it easier to see them all, due to the number of different sensors and sources of data
  • Internal changes
    • Jetson nano build support for OpenHD 3.0

Test notes

• The font dropdowns in QOpenHD may not update in both locations when you change the font
• In some cases QOpenHD might freeze on the ground station, this isn't a bug in the app itself but appears to be an issue with the Raspbian Buster 4.19.x kernel. We're testing an updated kernel to fix it.
• Air-side power stats (voltage/current from external sensors) may not be arriving in QOpenHD at the moment
• The boot screen may flicker for a moment when a TX is connected to the ground, this is expected at the moment (there is a bug in a system library we use)
• The first few messages may not show up on the boot screen at the moment
• The size of OSD elements in QOpenHD is fairly small on high resolution screens, HiDPI is not currently being detected automatically. If necessary you can increase the scale in the QOpenHD settings panel under App->Screen, you can also edit /boot/qopenhd.conf and reboot
• Video may stutter or freeze when ground recording to SD card is enabled with VIDEO_TMP=sdcard
  • This is an old problem, the settings file has had a note about it for probably a year or more
  • A temporary solution is to use VIDEO_TMP=memory instead
  • Will be resolved soon by separating the recording system from the rest of the video pipeline so it can't affect live flight
• Some parts of the old OSD may be reversed when Vector Open Telemetry is in use (#283)
