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.	2026-04-18 21:15:05 +02:00
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.	2026-04-10 08:37:38 +02:00
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 --------- Co-authored-by: RocketGod <57732082+RocketGod-git@users.noreply.github.com>	2025-12-12 17:43:51 +01:00
