摘　　要：蓝牙低功耗(BLE)技术由于其低功耗的特性被广泛应用到物联网领域。然而,数据点对点的传输协议以及传输范围小,组网能力差的限制使得BLE在物联网应用中大打折扣。此时,Mesh组网技术显得尤为重要,针对BLE提出的Mesh技术可以大范围地延伸BLE设备或节点的传输距离。首先介绍Mesh网络的特点,再从路由选择算法、广播信道的局限以及睡眠模式这三方面分析现有BLE Mesh技术的不足并展望了其发展前景。Bluetooth Low Energy（BLE） technology is widely used in the field of Internet of things（IOTs） because of its low energy characteristics. However, the point-to-point data transmission protocol, small transmission rang, and the network capacity restrictions make the application of the BLE to Internet of things greatly limited. Thus, Mesh networking technology is particularly important.The Mesh technology for BLE will make the Bluetooth device/Node to extend the range of information transmission. In this paper,we first introduce the characteristics of Mesh networks and node data control of BLE Mesh, then analyze the shortcomings of BLE Mesh technology from the aspects of routing algorithm, the limitation of advertising channels and sleep mode, and finally the outlook for BLE Mesh network is discussed.
