Parameters & Protocol
Auto-detects standard JBD/Xiaoxiang (FF00/FF01/FF02) and the newer ECO-WORTHY AA-command profile (0001/0002/0003). Live monitoring works for both. EEPROM / protection-threshold writes stay locked until the exact BMS register map is verified.
The reply is shown in the communication log on the Info tab.

About This Tool
Uses live ADS-B positions from OpenSky Network to estimate forward-scatter geometry between Points A and B set in the Endpoints card. Assumes a 1 W transmitter and ~25 dBi dish at each station, -100 dBm noise floor. Doppler shift is estimated per leg (A↔aircraft, aircraft↔B) from ADS-B ground speed/heading. Geometry only — not a guarantee of a completed QSO. Free anonymous OpenSky access is rate-limited; avoid short auto-refresh intervals.
