torlando-techandClaude Opus 4.7 612f44e274 feat(lxst): Codec2-700C (ULBW) default profile + T:CALL_ANSWER hook
Adds two profile constants beyond the existing LXST_PROFILE_LBW (0x30,
Codec2-3200): LXST_PROFILE_VLBW (0x20, Codec2-1600) and
LXST_PROFILE_ULBW (0x10, Codec2-700C). Default is now ULBW — a 700C
frame fits comfortably inside an SF7-9 LoRa packet, which is the
target medium for pyxis voice. The previous 3200bps default was 4.5x
larger and unsuitable for the radio path.

Profile is selectable at runtime via T:CALL_PROFILE [hex]. Replaces
five hardcoded LXST_PROFILE_LBW sites: three audio-init paths in
call_process_signal and two profile-negotiation send_signal calls.

Adds T:CALL_ANSWER for harness pyxis-as-callee testing — sets the
same _call_answer_pending flag the UI button does so call_answer()
runs on the main loop in its proper context. Validates against
real LXST.Telephony.Telephone callers.

Validated: pyxis dialed real LXST upstream Telephone bot, negotiated
ULBW end-to-end, reached STATUS_ESTABLISHED, decoded frames cleanly
both directions.

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.
