Struct rubble::phy::AdvertisingChannel

pub struct AdvertisingChannel(u8);

One of the three advertising channels (channel indices 37, 38 or 39).

Tuple Fields

0: u8

Implementations

impl AdvertisingChannel

pub fn first() -> Self

Returns the first (lowest-numbered) advertising channel.

pub fn iter_all() -> impl Iterator<Item = Self>

Returns an iterator that yields all 3 advertising channels in ascending order.

pub fn cycle(&self) -> Self

Returns the next advertising channel, or the first one if self is the last channel.

pub fn channel(&self) -> u8

Returns the channel index.

Channels 37, 38 and 39 are used for advertising.

pub fn rf_channel(&self) -> u8

Returns the physical RF channel corresponding to this advertising channel index.

RF channels 0, 12 and 39 are used for advertising.

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.

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

Performs copy-assignment from source.

impl Debug for AdvertisingChannel

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