tsbkdecode

Standalone test tool using the common P25 TSBK and DMR CSBK decoders, with local definitions, CLI entry point, decoder implementation, and CMake source list following src/testapp.

Build from the repository root:

cmake --build build --target tsbkdecode

Supply hexadecimal bytes as separate arguments or one quoted/contiguous string:

build/tsbkdecode tsbk 80 00 04 10 23 12 34 00 00 01
build/tsbkdecode csbk "9f 00 00 00 12 34 56 65 43 21"
build/tsbkdecode tsbk 800004102312340000016ed5

Raw input accepts 10 bytes (header and payload; CRC is generated) or 12 bytes (including CRC; failures warn and decoding continues). CSBK input uses the standard A5A5 CRC mask. Spaces, colons, commas, and per-byte 0x prefixes are supported.

Use --frame for a 45-byte P25 TSDU or 33-byte DMR burst, without modem tags. The P25 frame path decodes the first TSBK. Use --isp for inbound P25 signalling; outbound network/RFSS status broadcasts otherwise take precedence over the inbound authentication opcodes sharing their values.

Output includes decoded bytes, opcode, manufacturer/feature ID, last-block flag, message description, and fields extracted by the applicable decoder. Numbers are displayed in decimal and hexadecimal. Interpretation follows the common library's supported layouts; unknown opcodes and unimplemented decoders report errors rather than claim a complete interpretation. No channel frequency lookup is performed.

Exit status is 0 on successful decoding/help/version and 1 for malformed input, incorrect length or unsupported decoding. CRC failures alone do not cause a nonzero exit status, including with --frame. See --help for usage.
