读取btmon日志文件
读取btmon日志文件
提问于 2021-08-19 12:04:14
我使用btmon来监视从对等端发送/接收的蓝牙数据包。当我在Ubuntu机器上运行命令btmon时，我收集日志如下所述。我还从：https://manpages.debian.org/testing/bluez/btmon.1.en.html阅读了手册页。
我必须弄清楚要考虑哪个数据包作为发送数据包，哪个数据包要考虑作为接收所有数据。
我观察到日志中提到了一个Tx和Rx，也提到了一个时间，但我不知道数据包从哪里开始发送，以及数据包接收的终点在哪里。
基本上，我想知道对等设备在发送数据包后需要多长时间。

man btmon告诉我们它是btsnoop格式。
