Struct Scanner 

pub struct Scanner { /* private fields */ }

BLE Scanner for discovering HIVE nodes

Handles beacon reception, filtering, deduplication, and device tracking.

Note: This type requires the std feature for full functionality.

Implementations

impl Scanner

pub fn new(config: DiscoveryConfig) -> Self

Create a new scanner with default settings

pub fn set_time_ms(&mut self, time_ms: u64)

Set the current time (call periodically from platform)

pub fn set_filter(&mut self, filter: ScanFilter)

Set the scan filter

pub fn set_device_timeout_ms(&mut self, timeout_ms: u64)

Set device timeout in milliseconds

pub fn state(&self) -> ScannerState

Get current state

pub fn start(&mut self)

Start scanning

pub fn pause(&mut self)

Pause scanning

pub fn stop(&mut self)

Stop scanning

pub fn process_advertisement(&mut self, adv: ParsedAdvertisement) -> bool

Process a received advertisement

Returns true if this is a new or updated device that passes the filter.

pub fn get_device(&self, node_id: &NodeId) -> Option<&TrackedDevice>

Get a tracked device by node ID

pub fn get_node_id_for_address(&self, address: &str) -> Option<&NodeId>

Get node ID for an address

pub fn devices(&self) -> impl Iterator<Item = &TrackedDevice>

Get all tracked devices

pub fn devices_by_rssi(&self) -> Vec<&TrackedDevice>

Get devices sorted by RSSI (strongest first)

pub fn devices_by_hierarchy(&self) -> Vec<&TrackedDevice>

Get devices sorted by hierarchy level (highest first)

pub fn device_count(&self) -> usize

Get count of tracked devices

pub fn remove_stale(&mut self) -> usize

Remove stale devices

Returns the number of devices removed.

pub fn clear(&mut self)

Clear all tracked devices

pub fn find_best_parent( &self, our_level: HierarchyLevel, ) -> Option<&TrackedDevice>

Find the best parent candidate

Selects based on hierarchy level (prefer higher) and RSSI (prefer stronger).
