Nordic offers a complete solution for the Bluetooth mesh specification with the nRF5 SDK for Mesh and the nRF51 and nRF52 Series SoCs. It provides a powerful solution for product developers to take advantage of the new capabilities introduced by Bluetooth mesh. The nRF5 SDK for Mesh is intended to be used as a foundation for any Bluetooth mesh product development.
The addition of mesh networking capabilities to Bluetooth Low Energy enables extended range, increases the number of nodes and a many-to-many (m:m) communication topology. In a Bluetooth mesh network every received packet is broadcasted by relays, until the packet is received by the destination node (a so called managed flooding mesh.) A simple, but effective way of spreading information across the mesh network with no single point of failure. The mesh functionality is a significant update and enables new applications for Bluetooth in smart home, lighting, beaconing and asset tracking applications.
Nordic 為藍牙網格規范提供了一個完整的解決方案，其中包括針對網格的nRF5 SDK，以及nRF51和nRF52系列的SoCs。
它為產品開發人員提供了一個強大的解決方案，可以利用藍牙網格引入的新功能。
用於網格的nRF5 SDK是用於任何藍牙網格產品開發的基礎。
將網狀網絡功能添加到低功耗藍牙技術可以擴展范圍，增加節點數量和多對多(m:m)通信拓撲。
在藍牙網絡中，每一個接收到的數據包都被中繼廣播，直到數據包被目標節點接收(一個被稱為托管的洪水網格)。
一種簡單但有效的方法，可以將信息傳播到整個網狀網絡中，而不是單點故障。
網格功能是一個重要的更新，它可以在智能家居、照明、信標和資產跟蹤應用程序中支持藍牙的新應用。
