Struct EspNowConfig 

pub struct EspNowConfig { /* private fields */ }

Configuration for ESP-NOW traffic generation.

Used by both Central and Peripheral nodes when operating in ESP-NOW mode. Construct with EspNowConfig::default() then chain with_channel / with_phy_rate to override defaults — both nodes must agree on the channel for ESP-NOW frames to be received.

Implementations

impl EspNowConfig

pub fn with_channel(self, channel: u8) -> Self

Override the 2.4 GHz channel (1–14). Both central and peripheral must be configured with the same channel.

pub fn with_phy_rate(self, phy_rate: WifiPhyRate) -> Self

Force the ESP-NOW TX PHY rate (e.g. RateMcs0Lgi … RateMcs7Lgi, or a legacy rate). Applied per-peer via esp_now_set_peer_rate_config, which brings the radio up in started STA mode. Combine with with_ht40 for a 40 MHz bandwidth; without it the rate is sent at HT20 (for MCS rates) or the matching legacy mode. Without calling this (or with_ht40) the PHY is left at the driver default.

pub fn with_peer_mac(self, peer_mac: [u8; 6]) -> Self

Pre-configure the peer’s MAC address for manual pairing.

Switches off automatic magic-prefix pairing: no magic is sent, and each node accepts frames only from the configured peer MAC (source-MAC filtering applies from the first frame). The central must be given the peripheral’s MAC and vice-versa, and both nodes must use the same pairing mode for frames to parse.

pub fn channel(&self) -> u8

Configured 2.4 GHz channel.

pub fn phy_rate(&self) -> &WifiPhyRate

Configured PHY rate.

pub fn peer_mac(&self) -> Option<[u8; 6]>

Configured peer MAC for manual pairing, or None for automatic magic-prefix pairing.

pub fn with_ht40(self, secondary: SecondaryChannel) -> Self

Run the ESP-NOW TX at HT40 (40 MHz) with secondary as the HT40 secondary channel, using the configured with_phy_rate (default RateMcs0Lgi). Implies force_phy. Without this the PHY is HT20 (if a rate is forced) or the driver default. Verify on-air (CSI bandwidth field) that HT40 actually engaged.

pub fn secondary_channel(&self) -> Option<SecondaryChannel>

Configured HT40 secondary channel, or None for HT20.

pub fn force_phy(&self) -> bool

Whether the ESP-NOW TX PHY (rate + bandwidth) is forced via a per-peer rate config (set by with_phy_rate / with_ht40).

Trait Implementations

impl Default for EspNowConfig

fn default() -> Self

Returns the “default value” for a type.
