Struct WifiSnifferConfig 

pub struct WifiSnifferConfig { /* private fields */ }

Configuration for Wi-Fi Promiscuous Sniffer mode.

Construct with WifiSnifferConfig::default() then chain with_channel to override defaults.

Implementations

impl WifiSnifferConfig

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

Override the channel the sniffer locks to.

Must be a valid IEEE 802.11 primary channel number — pass the primary, not the wider-channel center notation that routers commonly display:

• 2.4 GHz: 1–14
• 5 GHz: 36, 40, 44, 48, 52, 56, 60, 64, 100, 104, 108, 112, 116, 120, 124, 128, 132, 136, 140, 144, 149, 153, 157, 161, 165 (regulatory-domain dependent — some restricted by country_info)

Center-channel labels (38, 46, ... for HT40; 42, 58, 106, ... for VHT80; 50, 114 for VHT160; 154 for the 153/157 HT40 pair) are not accepted here — esp_wifi_set_channel panics with InvalidArguments. For example, a router showing “channel 154” is using primary 153 (or 157); pass that primary and the chip will sniff the full 40 MHz block automatically per 802.11.

On dual-band chips (currently ESP32-C5), the band is auto-selected from the channel number — channels >= 36 switch the radio to BandMode::_5G, otherwise BandMode::_2_4G. On 2.4-GHz-only chips, passing any 5 GHz channel will fail at runtime.

pub fn channel(&self) -> u8

Configured channel (2.4 GHz: 1–14, 5 GHz: 36–165).
