PSDK Version 3.15.0 not Working with M300 on OSDK Port

[bigmick99]

With PSDK version 3.15.0, my application refuses to initialize the PSDK core on an M300 via the OSDK port:

(core) dji_core.c:113 Payload SDK Version : V3.15.0-beta.0-build.2318 Dec 10 2025 17:27:10
(utils) dji_sdk_verison_ack.c:183 Identify aircraft serial number = 1ZNPNAD001R036, Firmware = 3.4.18.68
(adapter) dji_access_adapter.c:354 Unknown mount position type, current sdk lib is not support, please contact dji for help
(core) dji_core.c:186 Access adapter init error, stat:255

The same software works flawlessly when compiled against PSDK version 3.14.0.

Dear Developer,

Greetings from DJI.

The latest PSDK version is no longer adapted for the M300. We suggest using PSDK version 3.9.2.

Thank you for choosing DJI. Have a great day and stay safe.

Dear DJI team,

Oh, that's a pity - especially since PSDK 3.14.0 worked flawlessly (at least for us) with the M300.

In addition, we try to have only one binary of our application for different drones (M300, M350, M400). We would highly appreciate if this would be possible also in the future with new PSDK versions!

Dear Developer,

Greetings from DJI.

We have communicated your concerns to our R&D team multiple times. However, the current strategy for the M300 RTK is to maintain its existing functionalities.

As the PSDK continues to evolve and introduce new features, we are no longer able to conduct full-scale testing and verification for the M300 RTK. In this situation, using newer versions of the PSDK with this specific aircraft may lead to unpredictable issues. Therefore, to ensure stability, we recommend using PSDK version 3.9.2 for your M300 RTK applications.

Thank you for choosing DJI. Have a great day and stay safe.

Best Regards,

DJI SDK Technical Support
