Previous Releases

OSDK 3.7 Highlights

Release Date: 2018-08-14

• Many new telemetry topics: Local position in both GPS and GPS-denied situations, data from ESCs, more detailed RC data and additional state information. For a full list see API Reference
• New APIs: KillSwitch API for emergency situations, new MobileDevice API in preparation of a future update
• Improved samples, docs and misc. updates Telemetry documentation has been revamped, samples now demonstrate some additional typical use cases

Improvements

• Deprecation Macros Some incorrect enum descriptions and old APIs - specfically the MobileCommunication class - are now deprecated, and a DJI_DEPRECATED macro has now been added
• Serial Connection Improvements Removed serialDevice validation routine that sometimes reported false positives
• Version String Improvements Hardware versions can now be accessed as Version::M210 etc.

OSDK 3.6 Highlights

• Major stereo vision stack update: New samples have been added for better rectification, disparity, and point cloud projection, accurate to a few cm.
• 3D object localization sample: Building on this stack, we now showcase a CNN-based 3D object detection and localization sample.
• Multiple performance improvements and bugfixes: Over twenty bugs have been fixed, and error handling and reporting have been made more robust.

Bug Fixes

• Samples hang when no data on serial line: The read thread now quits as expected, allowing clean exit.
• Memory Leaks: Fixed a few memory leaks in osdk-core, mainly related to buffers.
• Flight Control Sample height/altitude references: Previously, flight control samples used an incorrect reference for height, causing unpredictable real-world behavior. This has been fixed.
• Many other smaller bugfixes: Undefined return values, uninitialized variables, unreliable initial connection, etc.

Improvements

• Components initialize on successful activation: All components of Vehicle are now only initialized after activating successfully to allow error handling without the use of exceptions.
• Actionable error messages: Errors at various stages will now offer possible causes and remedies.
• Subscription cleanup: The vehicle initialization routine will automatically clean up if a previous subscription exists in an unclean state. There is a similar fix for the Advanced Sensing library as well.

Developer Notes

• Since program components are no longer initialized prior to activation, please ensure that the first API your program calls after initialization is activate.
• Please be sure to update your Advanced Sensing binary to 2.0.1, supporting x86 and 64-bit ARMv8.

OSDK 3.5 Highlights

• Access to live camera streams of M210 and M210 RTK: both FPV camera and main gimbaled camera
• Comprehensive Samples for live camera streams APIs: from basic data accessing samples to more advanced target tracking samples
• More complete license information is added

OSDK 3.4 Highlights

• Support for M210 and M210 RTK: OSDK features are now supported for M210. Currently, hardware synchronization and Multi-function IO are not supported.
• Stereo vision data from M210 and M210 RTK: Raw images and disparity map from stereo camera pairs of M210 are now available.
• M600 backward compatibility: Supports M600 firmware 1.0.1.20.
• ROS RTK support: RTK data via ROS topics.
• Protocol layer refactor: Improved performance and better abstraction.
• Platform Manager: Better abstraction layer for different computing platforms.
• Dynamic logging control: Developers can now start or stop logging.
• Encryption flag: Implemented getter/setter to modify encryption flag.

Bug Fixes

• Multi-threaded segmentation fault fix: Prevents access to unallocated memory in callback thread.
• Qt sample failed to initialize serial port: Fixed QThreadManager with renamed pure virtual functions and added mutex to protect init function from being called in two threads.
• OpenProtocol activation fix: Performs activation before using encryption.
• Waypoint push data event handling: Waypoint PushData variable was not set properly.
• Local position reference state fix: Returns state when setting local position.
