Struct LoraPacket 

pub struct LoraPacket {
    pub preamble_symbols: u16,
    pub explicit_header: bool,
    pub payload_len: u8,
    pub crc: bool,
    pub invert_iq: bool,
}

The LoRa parameters of a SetPacketParams command, from Tables 13-66 to 13-70.

Examples

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

// An eight-symbol preamble, an explicit header, a 20-byte payload, CRC on, standard IQ.
let packet = LoraPacket::from_link(&LinkSettings::new(7, 125_000), 20, false);
assert_eq!(packet.to_params(), [0x00, 0x08, 0x00, 0x14, 0x01, 0x00]);

Fields

preamble_symbols: u16

The preamble length in symbols.

explicit_header: bool

Whether the frame carries an explicit header; implicit when false.

payload_len: u8

The payload length to send, or the most a receiver accepts.

crc: bool

Whether the frame carries a CRC.

invert_iq: bool

Whether the IQ polarity is inverted, as LoRaWAN downlinks use.

Implementations

impl LoraPacket

pub fn from_link( link: &LinkSettings, payload_len: u8, invert_iq: bool, ) -> LoraPacket

Builds the packet parameters of a link for a payload.

Arguments

• link - the link settings, whose preamble, header, and CRC the frame uses.
• payload_len - the payload length to send, or the most to accept.
• invert_iq - true for inverted IQ polarity.

Returns

The parameters.

pub const fn to_params(&self) -> [u8; 6]

Returns the six parameter bytes: the preamble length, most significant byte first, then the header type, the payload length, the CRC type, and the IQ setup.

Returns

PacketParam1 to PacketParam6.

Trait Implementations

impl Clone for LoraPacket

fn clone(&self) -> LoraPacket

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Copy for LoraPacket

impl Debug for LoraPacket

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

Formats the value using the given formatter.

impl Eq for LoraPacket

impl Hash for LoraPacket

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 LoraPacket

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