Struct RadioConfig 

pub struct RadioConfig {
    pub freq_hz: u32,
    pub bw: Bandwidth,
    pub sf: u8,
    pub cr: u8,
    pub sync_word: u16,
    pub tx_power_dbm: i8,
    pub preamble_len: u16,
    pub cad: u8,
}

Complete LoRa radio configuration.

Wire layout (13 bytes, all little-endian):

[freq_hz:4] [bw:1] [sf:1] [cr:1] [sync_word:2] [tx_power_dbm:1] [preamble_len:2] [cad:1]

Fields

freq_hz: u32

Frequency in Hz (150_000_000 - 960_000_000 for SX1262).

bw: Bandwidth

sf: u8

Spreading factor (5-12).

cr: u8

Coding rate denominator (5-8). E.g. 5 = CR 4/5, 8 = CR 4/8.

sync_word: u16

tx_power_dbm: i8

Transmit power in dBm. Set to TX_POWER_MAX (-128) for the board’s maximum.

preamble_len: u16

Preamble length in symbols. Set to PREAMBLE_DEFAULT (0) for the firmware default (16 symbols). Valid range: 6–65535.

cad: u8

Channel Activity Detection (listen-before-talk) before TX. 0 = disabled, non-zero = enabled. Default: 1 (enabled).

Implementations

impl RadioConfig

pub fn validate(&self, power_range: (i8, i8)) -> Result<(), &'static str>

Validate fields against hardware limits.

pub fn resolve(self, power_range: (i8, i8)) -> Self

Resolve sentinel values to concrete defaults.

pub fn cad_enabled(&self) -> bool

Whether CAD (listen-before-talk) is enabled.

pub fn write_to(self, buf: &mut [u8]) -> usize

Serialize to fixed-size LE bytes. Returns number of bytes written (always 13).

pub fn from_bytes(buf: &[u8]) -> Option<Self>

Deserialize from fixed-size LE bytes.

Trait Implementations

impl Clone for RadioConfig

fn clone(&self) -> RadioConfig

Returns a duplicate of the value.

fn clone_from(&mut self, source: &Self)

Performs copy-assignment from source.

impl Debug for RadioConfig

fn fmt(&self, f: &mut Formatter<'_>) -> Result

Formats the value using the given formatter.

impl Format for RadioConfig

where Bandwidth: Format,

fn format(&self, f: Formatter<'_>)

Writes the defmt representation of self to fmt.

impl PartialEq for RadioConfig

fn eq(&self, other: &RadioConfig) -> bool

Tests for self and other values to be equal, and is used by ==.

fn ne(&self, other: &Rhs) -> bool

Tests for !=. The default implementation is almost always sufficient, and should not be overridden without very good reason.
