移远EC25-E在比利时拨号联网

EC25-EFA

公司一IOT设备在比例时使用移远EC25-E拨号联网时候发生异常，特将解决方法记录如下

情况说明

操作系统：ubuntu14
通过SSH登录发现拨号一切正常，ifconfig也正常,但就ping外网就不同。

解决思路

最后详细查看拨号日志才发现APN设置有问题,值为“3gnet” 3gnet的为中国联通的APN，那么现在使用的SIM卡运营商为“Proximus”，查资料得知此SIM卡运营商的APN为：internet.proximus.be 。具体修改如下(文件：/etc/ppp/peers/quectel-chat-connect)：

# /etc/ppp/peers/quectel-chat-connect
ABORT "BUSY"
ABORT "NO CARRIER"
ABORT "NO DIALTONE"
ABORT "ERROR"
ABORT "NO ANSWER"
TIMEOUT 30
"" AT
OK ATE0
OK ATI;+CSUB;+CSQ;+CPIN?;+COPS?;+CGREG?;&D2
# Insert the APN provided by your network operator, default apn is 3gnet
OK AT+CGDCONT=1,"IPV4V6","internet.proximus.be ",,0,0
OK ATD*99#
CONNECT

重新拨号后再次ping外网一切正常。

cat /dev/ttyUSB3 &
#查询SIM卡状态
echo -en "at+cpin?\r\n" > /dev/ttyUSB2 
#设定电话机能关
echo -en "at+cfun=0\r\n" > /dev/ttyUSB2 
#设定电话机能开
echo -en "at+cfun=1\r\n" > /dev/ttyUSB2
#获取SIM卡APN
