noble/noble: A Node.js BLE (Bluetooth Low Energy) central module (github.com)
noble/bleno: A Node.js module for implementing BLE (Bluetooth Low Energy) peripherals (github.com)
pybluez/pybluez: Bluetooth Python extension module (github.com)
这两个库都是支持全平台的（Linux/Windows/MacOS）
比较特殊的是，nodejs的ble库分为两套，noble做中心设备，bleno做外围设备。
