选择蓝牙低功耗（BLE）解决方案时的一个重要方面是分析其各种连接参数的能耗和所需的吞吐量，以构建最佳的低功耗物联网（IoT）应用并延长电池寿命。本文研究了各种BLE版本的能耗和数据吞吐量。我们已经测试了连接间隔对吞吐量的影响，并比较了与各种BLE版本和不同事务的吞吐量相关的功率效率。所提出的结果表明，较短的连接间隔增加吞吐量的读/写事务，但这不是通知和读/写没有响应事务的情况下。此外，对于每个BLE版本，能耗主要取决于数据量。所获得的结果为实现最佳BLE IoT应用提供了设计指南。
One important aspect when choosing a Bluetooth Low Energy (BLE) solution is to analyze its energy consumption for various connection parameters and desired throughput to build an optimal low-power Internet-of-Things (IoT) application and to extend the battery life. In this paper, energy consumption and data throughput for various BLE versions are studied. We have tested the effect of connection interval on the throughput and compared power efficiency relating to throughput for various BLE versions and different transactions. The presented results reveal that shorter connection intervals increase throughput for read/write transactions, but that is not the case for the notify and read/write without response transactions. Furthermore, for each BLE version, the energy consumption is mainly dependable on the data volume. The obtained results provide a design guideline for implementing an optimal BLE IoT application.
