GNU Radio Out-of-Tree module providing: - Complete TX chain: PHYEncode → FrameGen → CSSMod - Complete RX chain: CSSDemod → FrameSync → PHYDecode - NETWORKID extraction/encoding (0-255 range) - All SF (7-12) and CR (4/5-4/8) combinations - Loopback tested with 24/24 configurations passing Key features: - Fractional SFD (2.25 downchirp) handling - Gray encode/decode with proper inverse operations - gr-lora_sdr compatible decode modes - GRC block definitions and example flowgraphs - Comprehensive documentation Discovered RYLR998 sync word mapping: sync_bin_1 = (NETWORKID >> 4) * 8 sync_bin_2 = (NETWORKID & 0x0F) * 8

"""gr-rylr998: GNU Radio OOT module for RYLR998 LoRa modems.
|
|
|
|
Provides complete TX/RX blocks for RYLR998 LoRa modems with support for
|
|
the reverse-engineered NETWORKID → sync word mapping.
|
|
|
|
Blocks:
|
|
- css_demod: CSS demodulator (FFT peak detection)
|
|
- css_mod: CSS modulator (chirp generation)
|
|
- frame_sync: Preamble + sync word detection
|
|
- frame_gen: Header + preamble + SFD generation
|
|
- phy_decode: Gray decode → deinterleave → Hamming → dewhiten
|
|
- phy_encode: Whiten → Hamming → interleave → Gray encode
|
|
|
|
Utilities:
|
|
- networkid: NETWORKID ↔ sync word conversion
