抱怨我国造不出高端轴承，你知道日本NSK怎么做精密轴承的吗？
虽然其结构简单，很多小作坊都能制作一些粗糙的轴承，但其实轴承具有很高的技术含量，甚至可作为一个衡量一个国家科技、工业实力的重要标准。当今世界科技、工业强国无一例外是轴承研发、制造强国。

Bluetooth LE Node Statistics
The Bluetooth low energy (LE) network simulation captures these statistics as a structure. This structure is returned as an output by the
statistics object function of the bluetoothLENode object. The fields of this structure depend on the value of the Role property of the bluetoothLENode object.

Bluetooth Protocol Stack
The Bluetooth® Special Interest Group (SIG) [1] and [2] defines the protocol stack for Bluetooth low energy (LE) and Bluetooth basic rate/enhanced data rate (BR/EDR) technology. The fundamental objectives of these specifications is to develop interactive services and applications over interoperable radio components and data communication protocols.

Mathworks Matlab Bluetooth Toolbox
With the toolbox, you can configure, simulate, and analyze end-to-end Bluetooth communication links. You can create and reuse test benches to verify that your designs, prototypes, and implementations comply with the Bluetooth standard, including Bluetooth basic rate/enhanced data rate (BR/EDR) and low energy (LE). You can also assess coexistence, interference, localization, and LE Audio scenarios by modeling multiple layers of the Bluetooth protocol stack.
