Other Parts Discussed in Thread: Z-STACK, CC2538, CC2592
z-stack3.0协议栈开发指导手册中涉及安全设置的10.3.1.3章节中有如下一段话:
It is important to note that legacy devices (implementing R20 or before) will not be able to perform the TCLK exchange process, so if this policy is set to TRUE, legacy devices will not be able to join this network 。
请教一下怎么理解“ legacy devices ”这个描述?
