Struct rubble::phy::DataChannel

pub struct DataChannel(_);

One of 37 data channels on which data channel PDUs are sent between connected devices.

(channel indices 0..=36)

Methods

impl DataChannel

pub fn new(index: u8) -> Self

Creates a DataChannelIndex from a raw index.

Panics

This will panic if index is not a valid data channel index. Valid indices are 0..=36.

pub fn index(&self) -> u8

Returns the data channel index.

The returned value is always in range 0..=36.

pub fn rf_channel(&self) -> u8

Returns the RF channel corresponding to this data channel index.

RF channels 1-11 and 13-38 are used for data transmission.

pub fn freq(&self) -> u16

Returns the center frequency of this channel in MHz.

pub fn whitening_iv(&self) -> u8

Calculates the initial value of the LFSR to use for data whitening.

The value is a 7-bit value. The MSb will always be 0, and the 2nd MSb always 1 (Position 0). The LSb contains Position 6. Refer to the specification for details about the bit positions.

The polynomial is always x^7 + x^4 + 1.

Whitening is applied to PDU and CRC.
