In the interest of connecting with other PSDK developers, I'm starting this thread.

Share what you're currently working on and if you need any help.


I'm working on connecting a Jetson Xavier NX to the X-Port attachment and have been struggling to follow the Quick Start guide. If anyone is in a similar position, please let me know.


Cheers

Hello! I'm working with a Skyport V2, M300 RTK, and a UDOO x86 Advanced Plus development board running Ubuntu 16.04.

I've also found the online documentation to be hard to follow, so thanks to Joolzay for starting this thread. At the moment, I'm dealing with a "Command async send error" (log file attached) that occurs during PsdkCore_Init(). I suspect a problem in the HAL or OSAL, but the error is difficult to track down since we don't have access to the initialization source code.

Will appreciate any suggestions, and I'm happy to share any/all details of my setup.

Update: I didn't have the payload "bound" in the DJI Assistant 2 desktop program. Doing that resolved the communication issue.

Now I'm working on creating a "custom widget" with the example "test_widget.c." Anybody have widgets working? Do you have to interface with MSDK or can everything be done from PSDK?

Good luck to the other PSDK developers out there!

I have the exact same output in my first test.

Within the Assistant 2 software I was able to bind the gimbal successfully after starting the application. But the log output keeps the same as the one you uploaded.

Do you maybe have a hint for me on how to get this up and running?

Hmm, the only other thing I did to get mine working is update the drone firmware. Maybe that will help in your case? Since your PsdkCore_Init() function is generating errors, I also suggest double-checking that the information in app_info.h is complete. My crude understanding is that PsdkCore_init() checks to make sure you're running an approved and registered payload.

Best,
Will

Best,

I just got it working.

DJI support mentioned to me, that not every PSDK version is compatible with all Drone and X Port firmware versions. After updating the X Port firmware everything is working fine now :-)

Hi, I'm wondering if it would be easy to power and control a servo drop unit via SDK?

I am also looking into powering a liquid pump that would require switching on and off.

Is this something realistically possible to develop?

Sorry for the novice questions, I am very new to all this.

Thanks
