EC20无法获取ip

fevenor

EC20模块，型号EC20CFA-512-STD，通过转接板USB2.0连接MT3000，插上后设备页面展示正确识别，页面设置QMI协议连接端口/dev/cdc-wdm0，页面显示卡在“连接中……”。
Modem管理页面可以看到已经注册到网络中，通过uqmi工具也可以确认。

1. uqmi -d /dev/cdc-wdm0  --get-current-settings
   
2. {
   
3.         "pdp-type": "ipv4-or-ipv6",
   
4.         "ip-family": "ipv4",
   
5.         "mtu": 1500,
   
6.         "ipv4": {
   
7.                 "ip": "10.26.105.88",
   
8.                 "dns1": "202.101.172.37",
   
9.                 "dns2": "202.101.173.157",
   
10.                 "gateway": "10.26.105.89",
    
11.                 "subnet": "255.255.255.240"
    
12.         },
    
13.         "ipv6": {
    
14. 
    
15.         },
    
16.         "domain-names": {
    
17. 
    
18.         }
    
19. }

查看系统日志，卡在“udhcpc: sending discover”

“ cat /sys/class/net/wwan0/qmi/raw_ip” 显示为 “Y”
若直接执行echo "N" > /sys/class/net/wwan0/qmi/raw_ip ，报write error: Resource busy
通过页面终止后可以顺利写入，但一旦重新开启，raw_ip自动设置为Y

若页面选择3G协议连接ttyUSB3，可以正常获得ipv4地址及ipv6地址，但网速只有1~2M

通过AT指令获得的模块信息

1. ATI
   
2. 
   
3. Quectel
   
4. EC20F
   
5. Revision: EC20CFAR02A10M4G

请在/lib/netifd/proto/qmi.sh中将echo "Y" > /sys/class/net/$ifname/qmi/raw_ip改成echo "N" > /sys/class/net/$ifname/qmi/raw_ip

请在/lib/netifd/proto/qmi.sh中将echo "Y" > /sys/class/net/$ifname/qmi/raw_ip改成echo "N" > /sys/clas ...

这样可以获取ip了
有个新的问题，跑几个小时后，会断网，使用uqmi查看状态：

1. uqmi -d /dev/cdc-wdm0 --get-current-settings
   
2. "Out of call"
   
3. uqmi -d /dev/cdc-wdm0 --get-data-status
   
4. "disconnected"

复制代码

这个时候除了页面点终止，有什么命令可以放脚本里自动重连？

自己写一个脚本检测？
发现disconnected之后，执行 ifconfig wwan0 down && ifconfig wwan0 up

试了下，ifconfig wwan0 up后，modem_1_1_4不会重启获取ip，ifup modem_1_1 也不太行，得通过echo 0 > /sys/bus/usb/devices/1-1/bConfigurationValue的方式重连usb才行。
然后又出现了一个新问题，内核崩了，崩溃后就没usb了
