Fluxcore lets LR2021 radios listen on two frequencies
An experimental MeshCore firmware fork with LR2021-specific features including dual-frequency scanning, nearby weather-sensor readings, and ADS-B aircraft reports.
- For
- MeshCore users and LR2021 radio tinkerers
- Worth noticing
- The page lists aircraft reports on 978 and 1090 MHz, refreshed every ten minutes.
Field notes
Commands typed into chat activate several LR2021-only modes: `mt` scans both frequencies, `wx` surfaces readings from Ecowitt, Ambient, and La Crosse sensors, and `air` reports nearby aircraft on 978 and 1090 MHz every ten minutes. The dual-frequency scan is attributed to a custom PRAM patch in the LoRa chip; the homepage says this leaves the MCU free to rest. Other listed changes include time-of-flight ranging without GPS and separate buzzer, vibration, and LED switches.
