请问如何理解跳频中的单播跳频和广播跳频呢?
如果是单播跳频那么中心节点是如何与各节点之间同步的呢?
广播跳频是中心节点与边缘节点在同一时刻做跳频的意思吗?
求教!!!

TI这边能够解答一下吗?谢谢
Viki Shi:
The time spent on each channel is controlled through a parameter called dwell period that can be configured by the user to be anywhere between
15 ms to 250 ms. Channel hopping information of a node is exchanged to another node during the initial discovery and joining procedure performed
using asynchronous transmissions [1].Once channel hopping information of a neighbor is received, the TI 15.4-Stack SDK will track the hopping sequences of the neighbor hopping devices and enable successful unicast and broadcast transmissions.
Data exchange is achieved by the transmitter transmitting the frame on the receiving node’s channel (receiver directed transmissions).见: www.ti.com/…/swry025.pdf
