WISPR Ground Control and WISPR Flight Firmware Release Changelog

v1.13.2

• Update logo for WISPR Ground Control.

• Fix bug causing mission plans to be saved in a location non-accessible on the hand controller. Missions saved while using V1.13.0 will be automatically transferred to the SD card or correct location in internal storage. Missions saved on the hand controller can be migrated to the SD card using this guide https://wisprsystems.atlassian.net/wiki/x/HgApRg . We recommend using an SD card for storage to make transferring mission plans and pulling flight logs between your PC and hand controller easier.

• Hide mission slider to resume mission until the mission is fully updated to include the resume mission waypoint. A dialog now appears to show the mission is being updated to include the additional resume waypoint.

• Fix bug causing Figure 8 LiDAR calibration mission item to display as individual waypoints.

• Fix bug causing incorrect altitude to be displayed in WGC. The altitude is now based on the absolute altitude at takeoff. The altitude may show a negative number now, if the drone reaches an altitude lower than the takeoff altitude.

• Fix bug allowing payload to be changed in flight.

• Fix bug causing the “Reboot” dialog to appear while in flight.

• Fix bug causing drone to sometimes not face towards the ROI during a Structure Scan.

• Fix bug causing pre-arm display on screen to display longer than the pre-arm error is actually there.

• Fix bug causing Panoramic Waypoint and Panoramic Structure Scan mission types to not save and load correctly when saving mission plans.

• More closely verify terrain data from terrain server to match drone’s current absolute altitude.

• When planning Guyed and Monopole Structure Scans, automatically increase RTL Altitude to the greater value between top flight altitude and (structure height + 50ft), if needed.

• When planning General Structure Scans, automatically increase RTL Altitude to (structure height + 50ft), if needed.

• Set “Sony ILX-LR1 35mm” as default payload in Structure Scan mission planning when no payload is selected.

• Remove “Set Waypoint” feature while flying missions.

• Hide “Enable downward facing rangefinder” on Ranger unless UGCS payload selected.

• Fixed bug causing rangefinder to not be enabled by default on SkyScout.

• Fixed bug causing only one rally point item to be shown at a time when adding rally points.

• Fixed bug causing the “Waypoint” option to be selected when swapping between Rally Points and Mission Planning tabs.

• Fixed bug showing “Relative Altitude” on rally point items.

• Fixed bug causing compass calibration to not run properly if internal compass has been disabled due to compass drift.

• Fixed bug causing drone flight parameters to not be set correctly if there are missing drone flight parameters due to disabled settings.

• Add setting to disable user control during missions.

• Add WISPR Smart Controller button mapping to Settings > Controls page.

• Add Rally Points to the mission planning page. Rally Points allow the drone to RTL or return to the Rally Point rather than returning home. The drone will always return to the closest option between all Rally Points and the home position.

• Add ability to upload mission logs directly from WGC. Mission logs will now automatically be stored after every flight. The user can sign in to their WISPR Cloud account in the Settings > Cloud menu, then upload the logs to their Cloud account from the same menu.

• Fixed bug causing payloads to not initialize after swapping between payloads without first selecting “No Payload” option.
