<h4>三、5G 使用方法</h4>
<p>① 5G模块需要接上4根天线，以保证信号强度与网络通畅，</p>
<p>② 接上支持 5G 网络的 sim 卡，缺口朝外插入。</p>
<p>③ 识别模块</p>

<h4>四、通过AT命令维护模块</h4>
<pre><code class="language-shell">1.查看SIM卡是否插上
echo -e &quot;AT+CPIN?\r\n&quot; &gt;/dev/ttyUSB2
2.查看是否能接收信号（0-99之间为正常）
echo -e &quot;AT+CSQ\r\n&quot; &gt; /dev/ttyUSB2
3.确保模块注册运营网络
echo -e &quot;AT+COPS?\r\n&quot; &gt; /dev/ttyUSB2
4.模块数据网络是否OK
echo -e &quot;AT+CGREG?\r\n&quot; &gt; /dev/ttyUSB2
5.设置APN（设置接入点）
echo -e &quot;AT+COPS=3,2\r\n&quot; &gt; /dev/ttyUSB2
6.激活IP
echo -e &quot;AT+GTRNDIS=1,1\r\n&quot; &gt; /dev/ttyUSB2
7.查看激活是否成功
echo -e &quot;AT+CGDCONT?\r\n&quot; &gt; /dev/ttyUSB2
8.飞行模式
echo -e &quot;AT+CFUN=0\r\n&quot; &gt; /dev/ttyUSB2 （开启飞行）
echo -e &quot;AT+CFUN=1\r\n&quot; &gt; /dev/ttyUSB2 （关闭飞行）
9.USB网络设备模式
echo -e &#039;AT+QCFG=&quot;usbnet&quot;,0\r&#039; &gt; /dev/ttyUSB2 （关闭）
echo -e &#039;AT+QCFG=&quot;usbnet&quot;,1\r&#039; &gt; /dev/ttyUSB2 （开启）</code></pre>
