Struct HotspotConfig 

pub struct HotspotConfig {
    pub ssid: String,
    pub password: Option<String>,
    pub interface: String,
    pub band: HotspotBand,
    pub channel: u8,
}

Configuration for creating a WiFi hotspot.

Use the builder pattern to configure hotspot settings before passing to WifiManager::start_hotspot_with_config().

Example

use rpi_host::{WifiManager, HotspotConfig, HotspotBand};

let wifi = WifiManager::new()?;

// Basic configuration
let config = HotspotConfig::new("MyHotspot")
    .with_password("password123");

// Advanced configuration
let config = HotspotConfig::new("My5GHotspot")
    .with_password("securepass")
    .with_band(HotspotBand::A)
    .with_channel(36);

wifi.start_hotspot_with_config(config)?;

Fields

ssid: String

The SSID (name) for the hotspot.

password: Option<String>

Optional password for the hotspot.

If None, creates an open network. If Some, must be at least 8 characters.

interface: String

The wireless interface to use.

Defaults to “wlan0”.

band: HotspotBand

WiFi frequency band to use.

Defaults to 2.4GHz (HotspotBand::Bg) for maximum compatibility.

channel: u8

WiFi channel to use.

Set to 0 for automatic channel selection.

Implementations

impl HotspotConfig

pub fn new(ssid: impl Into<String>) -> Self

Create a new hotspot configuration with the given SSID.

Uses default values:

• No password (open network)
• Interface: wlan0
• Band: 2.4GHz
• Channel: auto

pub fn with_password(self, password: impl Into<String>) -> Self

Set the hotspot password (must be at least 8 characters).

pub fn with_interface(self, interface: impl Into<String>) -> Self

Set the wireless interface to use.

pub fn with_band(self, band: HotspotBand) -> Self

Set the frequency band.

Use HotspotBand::Bg (2.4GHz) for maximum device compatibility, or HotspotBand::A (5GHz) for faster speeds with compatible devices.

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

Set the WiFi channel.

For 2.4GHz, valid channels are typically 1-11 (varies by region). For 5GHz, common channels include 36, 40, 44, 48, 149, 153, 157, 161. Set to 0 for automatic selection.

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

Performs copy-assignment from source.

impl Debug for HotspotConfig

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