Commands for settings some filters fail

sq5x · March 12

Hi All,

I can successfully read NRL, NRS, RNN, ANFL, and ANFT states from slice status messages (e.g. nrl=0, nrs=1, rnn=0). Changes made in Maestro are reflected correctly.

However, when I try to set them using slice “slice set 0 nrs=1”, the radio responds with error 5000002D.

Standard properties like nb, nr, etc… work fine with “slice set 0 nb=1”.

Is there a different command format for NRL/NRS/RNN/ANFL/ANFT?
Or are these not yet exposed in the public TCP API?

Running v4.1.5 firmware.
Licensed version: v4

Any guidance appreciated!

All good, finally I sniffed all commands from SmartSDR using Wireshark. :-)

What was the fix?

To fix the issue, I used Wireshark to sniff proper commands to be send.

Any chance you might share these to save us some wireshark time?

No problem Gary. This is what I used in my app…
All commands use: slice set <slice_number> <key>=<value>

AUDIO

audio_level=<0-100> Volume

AGC (Automatic Gain Control)

agc_mode=<off|slow|med|fast> AGC mode
agc_off_level=<0-100> Gain (when AGC mode = off)
agc_threshold=<0-100> AGC threshold (when AGC mode != off)

Thank you! There were 4 of those that I couldn't get working and was trying to avoid using wireshark to figure it out. lms_nr , lms_anf, speex_nr, rnnoise.

Thanks for sharing!
