RT-Thread获取网络状态

可以通过msh命令行中的ifconfig来查看网络状态,不过一般都是在代码中查看。

首先包含头文件#include <netdev.h>

/* whether the network interface device is 'up' (set by the network interface driver or application) */
#define NETDEV_FLAG_UP                 0x01U
/* if set, the network interface device has broadcast capability, only supported in the 'lwIP' stack */
#define NETDEV_FLAG_BROADCAST          0x02U
/* if set, the network interface device has an active link (set by the network interface driver) */
#define NETDEV_FLAG_LINK_UP            0x04U
/* if set, the network interface device is an ethernet device using ARP, only supported in the 'lwIP' stack */
#define NETDEV_FLAG_ETHARP             0x08U
/* if set, the network interface device is an ethernet device, only supported in the 'lwIP' stack */
#define NETDEV_FLAG_ETHERNET           0x10U
/* if set, the network interface device has IGMP capability, only supported in the 'lwIP' stack */
#define NETDEV_FLAG_IGMP               0x20U
/* if set, the network interface device has MLD6 capability, only supported in the 'lwIP' stack */
#define NETDEV_FLAG_MLD6               0x40U
/* if set, the network interface device connected to internet successfully (set by the network interface driver) */
#define NETDEV_FLAG_INTERNET_UP        0x80U
/* if set, the network interface device has DHCP capability (set by the network interface device driver or application) */
#define NETDEV_FLAG_DHCP               0x100U

获取连网状态:

    if(!netdev_is_internet_up(netdev_get_by_name("ec200x"))){
        LOG_I("network error");
        return -1;
    }
