VasylSamoilov fc5beb0c09 FLEX RX: fix long-address numeric decode, improve short message format (#3136)
- Fix long-address numeric message decoding: read body[0] from Vy (j+1)
  for multi-word messages, from w1 for single-word. Fix MF word count
  for long addresses (n_field words, not n_field+1).
- Fix long-address short message: read 5 additional BCD digits from Vy
  for 8-digit decode.
- Fix BCD table: index 10 is '.' (dot) not ' ' (space) in both RX and TX.
- Clean up address decode: identify address type by value range per
  Table 3.8.1-1. Remove is_group/is_temp_group from packet structs.
- Rename SMSG to SHORT. Format message payload directly in baseband:
  TONE, NUM abc, SRC N, SRC N N=M R=R, RESERVED hex.
- Add BIW1 heartbeat packet (biw_field=0xFF) on every decoded frame.
- Move timezone table to file scope, simplify console log_message,
  add No signal initial status, simplify serial BIW output format.

VasylSamoilov cf44076a34 FLEX RX: comprehensive decoder rewrite (#3131)
Baseband (proc_flex.cpp):
- Fix numeric vector field width (3-bit n+1 for types 3,4,7)
- Fix capcode range classification for long address components
- Add long address decode (Set 1-2, 1-3/1-4, 2-3)
- Add vector checksum validation (4-bit nibble sum)
- Add tone-only boundary detection via vector pre-scan
- Add idle phase detection (skip all-zeros/all-ones before BCH)
- Skip spurious TON for capcode 1 (BCH-corrected idle artifact)
- Add BIW parsing: SSID1/SSID2, DATE, TIME, TZ, SYSMSG, CHAN
- Add alpha fragment flags: frag, more_frag, seq, new, maildrop, sig
- Add secure message enc= field (alpha/binary/separate)
- Add numbered numeric flags: seq, new, fmt
- Add HEX/Binary header decode: block_bits, new, maildrop, rtl
- Add short instruction decode: temp group slot/target, sys events
- Add short message (SMSG) decode: tone/numeric/source/numbered
- Add group/temp-group/priority flags per address
- Add S2 C-pattern detection with ±1 symbol boundary correction
- Extract FIW roaming, repeat, traffic fields
- Replace snprintf with lightweight str_* helpers (no heap/_sbrk)
- Mark uncorrectable BCH words as ? instead of aborting phase
- ETX/NUL handling: trim trailing padding, show mid-message as ?

App (ui_flex_rx.cpp):
- Add status bar: cycle/frame, bitrate, polarity, time, timezone
- Add network info bar: LID, CZ, CC, roaming flag
- Pipe-delimited serial output for all message types
- BIW events to serial and status bar (not console)
- Human-readable console: +GRP for temp group, G/TG/P flags
- USB serial via UsbSerialAsyncmsg

Packet (flex_defs.hpp):
- uint64_t capcode (long address support)
- 256-byte message buffer
- Fragment flags, BIW raw values, address type, group/priority

Known limitation: phase label unreliable on multi-phase modes
(3200/2FSK, 6400/4FSK). Data always decodes correctly.

RocketGod c53adfc765 Refactor FLEX RX UI to use console for messages (#2890) 2025-12-14 10:08:39 -08:00
RocketGod 472571b1ed Refactor FLEX RX UI to add color cycling and message log (#2885)
Replaces the console with a scrollable menu view for displaying FLEX messages, adds support for cycling text colors, and implements message logging with line wrapping and persistence. Also refactors frequency handling for persistence and updates UI element layout and initialization.

Tim Elfelt 106e56abc3 FLEX pager app (#2883)
* Add FLEX pager support

- Introduced a new FLEX configuration function in baseband_api.
- Added FLEX application view and associated UI elements.
- Implemented FLEX processing logic in proc_flex, including demodulation and message handling.
- Updated CMakeLists to include new FLEX source files and headers.
- Enhanced message system to support FLEX-specific messages and statistics.

This commit lays the groundwork for FLEX pager functionality, allowing for the reception and processing of FLEX messages.

* Fixed baseband and moved app to external with some other fixes.

* Format code
