Implementations

impl LoRaConfig

pub fn from_profile(profile: LoRaProfile, frequency_mhz: f32) -> Self

Create configuration from profile

pub fn eu868(profile: LoRaProfile) -> Self

pub fn us915(profile: LoRaProfile) -> Self

US 915 MHz band (902-928 MHz)

pub fn time_on_air_ms(&self, payload_bytes: usize) -> u32

Calculate time on air for a packet (in milliseconds)

Based on Semtech LoRa modem designer’s guide formulas.
