Codec2-3200 is a SPEECH codec — pure-tone round-trip retains only ~12% of input RMS. The 1kHz-sine variant of the LXST QoS test worked but tested the codec on its worst-case input. Switch I2SCapture::setInjectSine to generate a synthesized voice- like signal instead of a pure sine: F1 at the freq arg (default 730Hz, "ah" formant), F2 at 1.5·F1, F3 at 3.3·F1, all summed with weights 0.55 / 0.30 / 0.15, modulated by a 120Hz amplitude envelope that emulates glottal pulses. Phase-continuous so the encoder never sees a discontinuity. Codec2 retains far more energy on this content (~5400 RMS vs the ~1900 the sine produced) — same gate, much wider quality margin. Validated end-to-end: pyxis_rms=4378 bot_rms=5438 decode_fail=0+0 PASS The LXST harness drives this via the same T:CALL_INJECT command (API unchanged); only the in-firmware generator changed.

Pyxis
An LXMF and LXST client firmware for T-Deck, built on a highly modified fork of microReticulum
Very much WIP, don't expect stability :)
Features
Reticulum transport over:
- RNode-compatible LoRa
- AutoInterface (local wifi)
- TCP Client
- BLE Interface (barely working if at all)
Other features:
- GPS-synced time
- One really annoying beep when you get a new message (user toggle)
- View the announce stream
- Choose a propagation node (and sync with it) (fixed in v0.2.1)
- Set auto announce timer
- Light up keyboard (user toggle)
Will crash in about 5 minutes of normal use (sorry)I had 5d uptime on v0.2.0 with BLE disabled- Make LXST voice calls (codec2 only, quality sounds horrible coming out the other end in Columba, needs work)
Why "Pyxis"
Pyxis, latin for "compass," is a constellation in the southern sky depicting a mariner's compass. Small but essential, the compass ensures every message finds its destination - even when the path is uncertain.
