  • RPI3才出来没多久,又遭到seeed的追虐。BBGW也是Beablebone系列中首款支持内建(Built-in)Wi-Fi(MIMO技术)和BLE(4.1 LE)的开发板。

嗯,这个easy, easy。一个SoftAP0, 一个usb0,一个wlan0,分别对应的IP为:192.168.8.1,192.168.7.2,192.168.2.104。确实有3个IP地址。解决了这个问题,再用route命令来查看路由设置

这下不用担心学无所用了吧,很明显,wlan0负责处理192.168.2.0/24及192.168.8.0/24的所有路由转发,而usb0则负责所有192.168.7.0/24的路由转发!

如果没看懂,骚年,补补网络基础知识吧!

然而还有BLE,咱也体验一下。准备小蓝牙音箱一个

在控制台命令窗口模式下,执行BLE配置及连接命令,下面的命令输出列表供参考
