关于DW1000的广播问题

翻滚吧六宝

我学习到目的短地址为2个字节的时候把目的地址设为0xFFFF是广播模式，那目的地址为长地址，有八个字节的时候，是不是应该把目的地址设为0xFFFFFFFFFFFFFFFF呢？

广播的方法应该需要去查一下802.15.4 MAC地址广播

感谢回复，我再去学习一下

但可以确定的是 用户手册只有FFFF 没有16个F的字段 同时在我上一条回复中  没有提到broadcast这个词汇

7.2.3 Register file: 0x01 – Extended Unique Identifier
ID Length
(octets)
Type Mnemonic Description
0x01 8 RW EUI Extended Unique Identifier – the 64-bit IEEE device address
Register map register file 0x01 is the Extended Unique Identifier register. For IEEE 802.15.4 compliance
every device should have a unique 64-bit device identifier. The high-order 24-bits of the EUI are a company
identifier assigned by the IEEE Registration Authority, (see http://standards.ieee.org/develop/regauth/oui/),
to the manufacturer. The low 40-bits of the EUI are the extension identifier uniquely chosen by the
manufacturer for each device manufactured and never repeated. The resultant EUI is a globally unique
identifier. It is expected that manufacturers who need to comply with this requirement will register with the
IEEE Registration Authority and generate and maintain their own EUI extension identifier numbering space to
ensure its uniqueness for every device made
说实话他说这个64地址是种MAC地址，但MAC地址不是48位么

The Destination Address if present must:
o Be the (short 16-bit) broadcast address (0xFFFF)
o Or be a short (16-bit) address matching the SHORT_ADDR programmed in Register file: 0x03
– PAN Identifier and Short Address
o Or be a long (64-bit) address matching the Register file: 0x01 – Extended Unique Identifier.
长地址时需要特别参考
