pub struct BLEScan { /* private fields */ }

Implementations

impl BLEScan

pub fn active_scan(&mut self, active: bool) -> &mut Self

pub fn filter_duplicates(&mut self, val: bool) -> &mut Self

pub fn limited(&mut self, val: bool) -> &mut Self

Set whether or not the BLE controller only report scan results from devices advertising in limited discovery mode, i.e. directed advertising.

pub fn filter_policy(&mut self, val: ScanFilterPolicy) -> &mut Self

Sets the scan filter policy.

pub fn interval(&mut self, interval_msecs: u16) -> &mut Self

Set the interval to scan.

pub fn window(&mut self, window_msecs: u16) -> &mut Self

Set the window to actively scan.

pub fn on_result( &mut self, callback: impl FnMut(&mut Self, &BLEAdvertisedDevice) + Send + Sync + 'static ) -> &mut Self

Set a callback to be called when a new scan result is detected.

• callback first parameter: The reference to Self
• callback second parameter: Newly found device

pub fn on_completed( &mut self, callback: impl FnMut() + Send + Sync + 'static ) -> &mut Self

pub async fn find_device( &mut self, duration_ms: i32, callback: impl Fn(&BLEAdvertisedDevice) -> bool + Send + Sync ) -> Result<Option<BLEAdvertisedDevice>, BLEError>

Asynchronously finds a device.

Examples

let ble_device = BLEDevice::take().unwrap();
let ble_scan = ble_device.get_scan();
let name = "Device Name To Be Found";
let device = ble_scan.find_device(10000, |device| device.name() == name).await.unwrap();

pub async fn start(&mut self, duration_ms: i32) -> Result<(), BLEError>

pub fn stop(&mut self) -> Result<(), BLEError>

pub fn get_results(&mut self) -> Iter<'_, BLEAdvertisedDevice>

pub fn clear_results(&mut self)
