4G、5G模块的使用
ECP1001支持移远的4G模组EM05和5G模组RM500U。
1. 设备连接
把模块插入到 pcie 插槽中，接入 SIM 卡和天线，天线是使用的 IPEX 4代的天线。
在控制台输入 lsusb，显示有Quectel字样的设备就代表连接成功了。
lsusb
Bus 002 Device 001: ID 1d6b:0003 Linux Foundation 3.0 root hub
Bus 001 Device 003: ID 2c7c:0125 Quectel Wireless Solutions Co., Ltd. EC25 LTE modem
Bus 001 Device 002: ID 1a86:80a0 QinHeng Electronics USB2.0 HUB
Bus 001 Device 001: ID 1d6b:0002 Linux Foundation 2.0 root hub
Bus 004 Device 001: ID 1d6b:0003 Linux Foundation 3.0 root hub
Bus 003 Device 001: ID 1d6b:0002 Linux Foundation 2.0 root hub
2. 拨号上网
在Debian和Ubuntu中都可以使用移远提供的拨号软件去拨号。 你可以自行编译源码或者直接下载我们已经编译好的软件来使用
地址如下：Quectel-CM
2.1 编译quectel-CM源码
#更新软件
sudo apt update
#获取依赖软件
sudo apt install make gcc git busybox udhcpc
#解压源码包
unzip Quectel_QConnectManager_Linux_V1.6.8.zip
cd Quectel_QConnectManager_Linux_V1.6.8
#编译
make
之后就会得到可执行的quectel-CM程序。
2.2 拨号
在ubuntu系统中需要关闭默认的ModemManager服务，要不拨号系统会有冲突，debian则不用
sudo systemctl stop ModemManager
sudo systemctl disable ModemManager
拨号命令如下，其中APN根据手机卡运营商而定
#-s参数指定数据连接的APN
sudo ./quectel-CM -s APN &
#APN:
移动："cmnet"
联通："3gnet"
电信："ctnet"
测试用的 是移动卡所以使用的命令如下
例如指定移动的APN
sudo ./quectel-CM -s cmnet &

拨号成功后即可用ifconfig来看到它分配的ip地址
4G是wwan0
5G是usb0
如果遇到DNS的问题，则可以通过如下命令导入aliyun的DNS
echo "nameserver 223.5.5.5" | sudo tee /etc/resolv.conf
3.开启自动启拨号
为了方便我们可以把quectel-CM复制到系统的可执行目录去
sudo cp quectel-CM /usr/bin/ -f
3.1 创建脚本并加入执行权限
sudo vim /opt/auto_quectel.sh
sudo chmod +x /opt/auto_quectel.sh
脚本内容如下
/opt/auto_quectel.sh
#!/bin/bash
# 等待 /dev/ttyUSB 出现
while [ ! -e /dev/ttyUSB* ]; do
sleep 1
done
quectel-CM
3.2 添加自启动配置
创建配置文件，在/etc/systemd/system/目录下创建一个quectel-dial.service配置文件，内容如下
[Unit]
Description=auto_quectel daemon
After=network.target systemd-udev-settle.service
Wants=systemd-udev-settle.service
[Service]
ExecStart=/opt/auto_quectel.sh
Restart=always
Type=simple
User=root
[Install]
WantedBy=multi-user.target
启用和开启自启动服务
sudo systemctl daemon-reload
sudo systemctl enable quectel-dial
sudo systemctl start quectel-dial
