EG800K-EU 使用 ECM 模式 usb option驱动。
通过 AT指令查询状态正常。
通过udhcpc可以获取到 IP
root@buildroot:~# udhcpc -i usb1
udhcpc: started, v1.35.0
udhcpc: broadcasting discover
udhcpc: broadcasting discover
udhcpc: broadcasting select for 192.168.43.100, server 192.168.43.1
udhcpc: lease of 192.168.43.100 obtained from 192.168.43.1, lease time 86400
但是无法ping通 8.8.8.8，请问是什么原因呢？
root@buildroot:~# ping -I usb1 8.8.8.8
