Struct PacketStatus 

pub struct PacketStatus {
    pub rssi_dbm: Decibels,
    pub snr_db: Decibels,
    pub signal_rssi_dbm: Decibels,
}

The signal levels of the last LoRa packet received.

Examples

use pamoja_radios::sx127x::status::{PacketStatus, Port};

// RegPktSnrValue 0xF6 and RegPktRssiValue 0x30, heard at 868.1 MHz.
let packet = PacketStatus::from_bytes([0xF6, 0x30], Port::High);
assert_eq!(packet.snr_db.to_string(), "-2.50");
assert_eq!(packet.rssi_dbm.to_string(), "-109.00");
assert_eq!(packet.signal_rssi_dbm.to_string(), "-111.50");

Fields

rssi_dbm: Decibels

The RSSI averaged over the packet, in dBm: the port’s offset plus PacketRssi.

snr_db: Decibels

The estimated signal-to-noise ratio, in dB: PacketSnr, a two’s complement byte, divided by 4.

signal_rssi_dbm: Decibels

The strength of the packet itself, in dBm: the RSSI, lowered by the SNR when the packet arrived below the noise floor, as the datasheet computes it.

Implementations

impl PacketStatus

pub const fn from_bytes(bytes: [u8; 2], port: Port) -> PacketStatus

Decodes RegPktSnrValue and RegPktRssiValue.

Arguments

• bytes - PacketSnr and PacketRssi, the registers at 0x19 and 0x1A in that order.
• port - the port the packet was received on.

Returns

The three levels, exact to a hundredth of a decibel.

Trait Implementations

impl Clone for PacketStatus

fn clone(&self) -> PacketStatus

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Copy for PacketStatus

impl Debug for PacketStatus

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

Formats the value using the given formatter.

impl Eq for PacketStatus

impl Hash for PacketStatus

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 PacketStatus

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