Implementations§

source §

impl LoRaPacketParams

source

pub const fn new() -> LoRaPacketParams

Create a new GenericPacketParams.

This is the same as default, but in a const function.

Example

use stm32wlxx_hal::subghz::LoRaPacketParams;

const PKT_PARAMS: LoRaPacketParams = LoRaPacketParams::new();
assert_eq!(PKT_PARAMS, LoRaPacketParams::default());

source

pub const fn set_preamble_len(self, len: u16) -> LoRaPacketParams

Preamble length in number of symbols.

Values of zero are invalid, and will automatically be set to 1.

Example

use stm32wlxx_hal::subghz::LoRaPacketParams;

const PKT_PARAMS: LoRaPacketParams = LoRaPacketParams::new().set_preamble_len(0x1234);

source

pub const fn set_header_type(self, header_type: HeaderType) -> LoRaPacketParams

Header type (fixed or variable).

Example

Set the payload type to a fixed length.

use stm32wlxx_hal::subghz::{HeaderType, LoRaPacketParams};

const PKT_PARAMS: LoRaPacketParams = LoRaPacketParams::new().set_header_type(HeaderType::Fixed);

source

pub const fn set_payload_len(self, len: u8) -> LoRaPacketParams

Set the payload length in bytes.

Example

use stm32wlxx_hal::subghz::LoRaPacketParams;

const PKT_PARAMS: LoRaPacketParams = LoRaPacketParams::new().set_payload_len(12);

source

pub const fn set_crc_en(self, en: bool) -> LoRaPacketParams

CRC enable.

Example

Enable CRC.

use stm32wlxx_hal::subghz::LoRaPacketParams;

const PKT_PARAMS: LoRaPacketParams = LoRaPacketParams::new().set_crc_en(true);

source

pub const fn set_invert_iq(self, invert: bool) -> LoRaPacketParams

IQ setup.

Example

Use an inverted IQ setup.

use stm32wlxx_hal::subghz::LoRaPacketParams;

const PKT_PARAMS: LoRaPacketParams = LoRaPacketParams::new().set_invert_iq(true);

source

pub const fn as_slice(&self) -> &[u8]

Extracts a slice containing the packet.

Example

use stm32wlxx_hal::subghz::{HeaderType, LoRaPacketParams};

const PKT_PARAMS: LoRaPacketParams = LoRaPacketParams::new()
    .set_preamble_len(5 * 8)
    .set_header_type(HeaderType::Fixed)
    .set_payload_len(64)
    .set_crc_en(true)
    .set_invert_iq(true);

assert_eq!(
    PKT_PARAMS.as_slice(),
    &[0x8C, 0x00, 0x28, 0x01, 0x40, 0x01, 0x01]
);
