Hello! Happy to be part of the DJI community I'm having issues connecting my Raspberry Pi 4 running Raspbian 10 (kernel 5.4.83) to a Matrice 600 Pro. I've attached screenshots of the output after trying to run the sample code and of the DJI GO app when connected to the remote controller. I've switched the physical knob to F mode, and when the drone picks up on enough satellites, you can see it has successfully switched to F mode. However, the sample code tells me "Failed to obtain control. Your RC mode switch is not in mode F. (Is the RC connected and paired?)"
The pi is connected to the API port of the A3 flight controller using this product:

which is recommended on this page of the OSDK documentation:

I appreciate any advice anyone may have -- let me know if I should include more information about my setup. Thank you very much!

Hi! You might be better off posting your question in the 'developer' section of this forum.  That is way more active.

Hi, thank you!! I appreciate that, I hadn't even seen that part of the forum. I'll delete this post and try over there instead
