Struct LoraModulation 

pub struct LoraModulation {
    pub spreading_factor: u8,
    pub bandwidth: LoraBandwidth,
    pub coding_rate: CodingRate,
    pub low_data_rate_optimization: bool,
}

The LoRa parameters of a SetModulationParams command, from Tables 13-47 to 13-50.

Examples

use pamoja_lora::LinkSettings;
use pamoja_radios::sx126x::config::LoraModulation;

// SF12 at 125 kHz needs low data rate optimization.
let modulation = LoraModulation::from_link(&LinkSettings::new(12, 125_000)).unwrap();
assert_eq!(modulation.to_params(), [0x0C, 0x04, 0x01, 0x01]);

Fields

spreading_factor: u8

The spreading factor, 5 to 12.

bandwidth: LoraBandwidth

The signal bandwidth.

coding_rate: CodingRate

The coding rate.

low_data_rate_optimization: bool

Whether low data rate optimization is on.

Implementations

impl LoraModulation

pub fn from_link(link: &LinkSettings) -> Option<LoraModulation>

Builds the modulation parameters of a link.

Arguments

• link - the link settings, whose spreading factor, bandwidth, coding rate, and low data rate optimization the radio must match.

Returns

The parameters, or None when the link’s bandwidth is not one the SX126x offers.

pub const fn to_params(&self) -> [u8; 4]

Returns the four parameter bytes: SF, BW, CR, and LowDataRateOptimize.

Returns

ModParam1 to ModParam4.

Trait Implementations

impl Clone for LoraModulation

fn clone(&self) -> LoraModulation

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Copy for LoraModulation

impl Debug for LoraModulation

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

Formats the value using the given formatter.

impl Eq for LoraModulation

impl Hash for LoraModulation

fn hash<__H: Hasher>(&self, state: &mut __H)

Feeds this value into the given Hasher.

fn hash_slice<H>(data: &[Self], state: &mut H)

where H: Hasher, Self: Sized,

Feeds a slice of this type into the given Hasher.

impl PartialEq for LoraModulation

fn eq(&self, other: &LoraModulation) -> 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.
