package com.codename1.bluetooth.le

BLE central role: scanning (BluetoothLE, ScanSettings, ScanFilter, ScanResult, BleScan), connections and the GATT client (BlePeripheral, connection events) and L2CAP connection-oriented channels (L2capChannel, L2capServer).

Obtain the entry point via Bluetooth.getInstance().getLE(). Any number of scans and per-peripheral GATT operations may run concurrently – an internal queue serializes operations toward the platform stack and every call returns its own AsyncResource.

Types

`class AdvertisementData`	The parsed payload of a BLE advertisement: local name, advertised service UUIDs, manufacturer data, service data and TX power.
`class BlePeripheral`	A remote BLE peripheral: connection lifecycle, GATT client operations and L2CAP channels.
`class BleScan`	Live handle of a running BLE scan returned by `BluetoothLE.startScan(ScanSettings, ScanListener)`.
`class BluetoothLE`	The BLE central role: scanning for peripherals and re-obtaining known ones.
`class ConnectionEvent`	Payload of a `ConnectionListener` callback describing a `BlePeripheral` state transition.
`interface ConnectionListener`	Observes `BlePeripheral` connection state transitions registered via `BlePeripheral.addConnectionListener(ConnectionListener)`.
`class ConnectionOptions`	Options for `BlePeripheral.connect(ConnectionOptions)`.
`enum ConnectionPriority`	Connection-interval preference requested via `BlePeripheral.requestConnectionPriority(ConnectionPriority)`.
`enum ConnectionState`	Lifecycle states of a `BlePeripheral` connection.
`class L2capChannel`	An open L2CAP connection-oriented channel – a raw bidirectional byte stream to a peripheral, obtained via `BlePeripheral.openL2capChannel(int, boolean)` on the central side or accepted from an `L2capServer` on the peripheral side.
`class L2capServer`	A listening L2CAP endpoint on the local device, opened via `BluetoothLE.openL2capServer(boolean)` when acting as a peripheral.
`class ScanFilter`	A single scan filter – all criteria set on one filter are AND-combined; multiple filters added to a `ScanSettings` are OR-combined.
`interface ScanListener`	Receives advertisement sightings during a scan started via `BluetoothLE.startScan(ScanSettings, ScanListener)`.
`enum ScanMode`	Power/latency trade-off of a BLE scan, mirroring Android’s scan modes.
`class ScanResult`	One advertisement sighting delivered to a `ScanListener` during a scan.
`class ScanSettings`	Options for a BLE scan started via `BluetoothLE.startScan(ScanSettings, ScanListener)`.
