Wi-Fi through one FPGA input — exact received packet
Brian Greenforest · September 17, 2026

129-byte 802.11 beacon, including FCS; no repaired or redacted bytes.
ESP8266 device addresses published with the owner's explicit permission.
PCAP timestamp is synthetic zero; its radiotap flag marks FCS-present.

FCS (125..128), transmitted little-endian: 88 79 f9 58
CRC32(frame[0:125]): 0x58f97988 — PASS
Known bytes at offsets 61..124: (37*i + 11) mod 256, i=0..63 — 512/512 bits match.

PHY header, separate from the MAC frame: 0a 04 08 04 f5 cb
SIGNAL: 1 Mb/s; LENGTH: 1032 us; CRC16 valid.
