Fibocom Modem连接Internet AT命令序列

Question

我试图通过AT命令与FIBOCOM调制解调器连接互联网。顺序如下。我对它有不同的技术，例如AT+COPS给运营商。但我想我不能再继续下去了。

        _serialPort.Write("AT\r");
        Thread.Sleep(2000);

        _serialPort.Write("ATZ\r");
        Thread.Sleep(2000);

        _serialPort.Write("ATE0+CMEE=1;+CREG=2\r");
        Thread.Sleep(2000);

        _serialPort.Write("AT+CPIN?\r");
        Thread.Sleep(2000);

        _serialPort.Write("AT+CSQ\r");
        Thread.Sleep(2000);

        _serialPort.Write("AT+CREG?\r");
        Thread.Sleep(2000);

        _serialPort.Write("AT+CSQ\r");
        Thread.Sleep(2000);

        _serialPort.Write("AT+CMGF=0\r");
        Thread.Sleep(2000);

        _serialPort.Write("AT+CIMI\r");
        Thread.Sleep(2000);

        _serialPort.Write("AT+CGSN\r");
        Thread.Sleep(2000);

        _serialPort.Write("AT+CPMS?\r");
        Thread.Sleep(2000);

        _serialPort.Write("AT+CGDCONT=1,\"IP\",\"infoteks\",\"0.0.0.0\",0,0\r");
        Thread.Sleep(2000);

        _serialPort.Write("AT+CGQMIN=1,1,0,0,4,31\r");
        Thread.Sleep(2000);

        _serialPort.Write("ATD*99***1#\r");
        Thread.Sleep(2000);

在这个序列完成之后，我得到了这些报告

NO CARRIER

我该怎么办？

Answer 1

命令是AT+MIPCALL=1，"APN"/r

apn是无访问点名，如果您给出正确的名称，它将返回ok，并且在某个时间之后，最多20秒，它将返回连接的ip地址。
