Struct Radio

pub struct Radio<'d, T: Instance> { /* private fields */ }

IEEE 802.15.4 radio driver.

Implementations

impl<'d, T: Instance> Radio<'d, T>

pub fn new( radio: Peri<'d, T>, _irq: impl Binding<T::Interrupt, InterruptHandler<T>> + 'd, ) -> Self

Create a new IEEE 802.15.4 radio driver.

pub fn set_channel(&mut self, channel: u8)

Changes the radio channel

pub fn set_cca(&mut self, cca: Cca)

Changes the Clear Channel Assessment method

pub fn set_sfd(&mut self, sfd: u8)

Changes the Start of Frame Delimiter (SFD)

pub fn clear_all_interrupts(&mut self)

Clear interrupts

pub fn set_transmission_power(&mut self, power: i8)

Changes the radio transmission power

pub async fn receive(&mut self, packet: &mut Packet) -> Result<(), Error>

Receives one radio packet and copies its contents into the given packet buffer

This methods returns the Ok variant if the CRC included the packet was successfully validated by the hardware; otherwise it returns the Err variant. In either case, packet will be updated with the received packet’s data

pub async fn try_send(&mut self, packet: &mut Packet) -> Result<(), Error>

Tries to send the given packet

This method performs Clear Channel Assessment (CCA) first and sends the packet only if the channel is observed to be clear (no transmission is currently ongoing), otherwise no packet is transmitted and the Err variant is returned

NOTE this method will not modify the packet argument. The mutable reference is used to ensure the packet buffer is allocated in RAM, which is required by the RADIO peripheral
