我试图通过Telit调制解调器访问数据，该调制解调器通过USB连接到嵌入式Linux主板（没有网络管理器）CC3200。
我已插入所有需要的驱动程序，并且我使用PPP守护程序将此ttyACM0设备连接到ppp接口，以便我可以通过ppp接口访问网络。
两天前我能够成功连接到网络并ping google.com。 但我没弄清楚实际上是什么让它起作用，不幸的是我失去了工作设置。
现在ppp peer拒绝同意IP。
我按照此链接进行了ppp设置：http://www.techytalk.info/manage-gsm-mobile-broadband-connections-without-network-manager-ubuntu-mint-debian/ 我在没有身份验证的情况下尝试。 我还添加了“nodeflate nomagic and demand＆＃39;在选项文件中。

为什么要拒绝协议。如何克服它。 nodeflate没有帮助。 为什么同行拒绝同意知识产权。在工作状态中，对等体本身建议使用范围为100.xxx.xxx.xxx的IP。
以下是路线输出

答案 0 :(得分：1)
前几天我得到了答案。 我正在使用需要为2的pdp contex 1。 喜欢：
'OK' 'AT+CGDCONT=2,"IP","ispapn"'
因为contex 1被保留。
