About the "NXDNScramblerKey=Auto" Command

[magentalin]

Hi,
In the video titled "NXDN - Le scrambler 15 bits, est-ce qu'il vous protège bien?" at around the 12:28 mark, I noticed you entered the command "NXDNScramblerKey=Auto." Regrettably, I couldn't find this command in the latest version of DSD, and my attempts to use it didn't initiate the process as expected. Could you kindly advise if there is an alternative command for automatically finding the NXDN Scrambler Key, or have I perhaps misunderstood something? Below is the command I used:
$ dsd -i /dev/dsp -o /dev/dsp -fi -NXDNScramblerKey=Auto

However, the only response I received was:

Setting symbol rate to 2400 / second
Enabling only GFSK modulation optimizations.
Decoding only NXDN 4800 baud frames.
Audio In/Out Device: /dev/dsp

Unlike in your tutorial, I didn't get the line "NXDN encryption key auto detection."
Could you please help me understand where I might be going wrong?

Lastly, I would like to express my sincere gratitude for each of your videos.
They have significantly enhanced my radio skills.

Thank you for your time and assistance.
