Package com.codename1.bluetooth.le

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.

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.
L2capServer	A listening L2CAP endpoint on the local device, opened via BluetoothLE.openL2capServer(boolean) when acting as a peripheral.
