Question

我尝试通过AT命令与FIBOCOM调制解调器连接互联网。顺序如下。我有不同的技术AT + COPS，例如运营商。但我想我不能再进一步了。

        _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);

完成此序列后，我收到了这些报告

NO CARRIER

我该怎么办？

Answer 1

命令是 AT + MIPCALL = 1， “APN”/ R

apn是访问点名称，如果您给出正确的名称，它将返回确定经过一段时间20秒后，它将返回连接的IP地址
