sim900a在lwip_ppp拔号时，已获取本地IP，根据IPCP协议，在重复申请IP地址包时，sim900a不响应。不知何解?

从PAP转到IPCP时，单片机向SIM900a发出了一条申请，好象是错的，那位大侠帮助分析一下？

7d后面的5e，是7e，7e是开头与结尾特殊字节，需要转换0x7e^0x20=0x5e。

已查到问题，是串口通信时使用了"RT_DEVICE_FLAG_STREAM"标识，凡是"\n"字符都加上"\r"。

只看该作者 · 2015-6-25 11:28

您好 sim9000a 使用 ppp协议上网在lwip验证获取IP之前需要将其怎样配置？
ppp协议上网进行网络数据传输的同时模块儿应该能进行短信接收吧？
短信收到 sim900a是实时AT命令通知的吗？
ppp数据接发过程有短信来了您是怎么处理的？
