	巨大八爪鱼：option.c、qcserial.c和usb_wwan.c这三个文件，瑞芯微SDK的linux内核里面Luckfox_Nova_SDK_250430/kernel/drivers/usb/serial本来就有，默认是没有开启编译的。如果想用内核里面自带的这三个文件，就得按照Quectel_LTE&5G_Linux_USB_Driver_User_Guide_V2.0.pdf文档说明去改里面的代码。不过我看到option.c里面已经有{ USB_DEVICE_AND_INTERFACE_INFO(QUECTEL_VENDOR_ID, QUECTEL_PRODUCT_EC200A, 0xff, 0, 0) }了，这个不用添加了，其他地方比如URB_ZERO_PACKET还有return -ENODEV可能还是得自己手动加，有点麻烦。涉及到的三个c文件的menuconfig菜单项： option.c USB_SERIAL_OPTION "USB driver for GSM and CDMA modems" qcserial.c USB_SERIAL_QUALCOMM "USB Qualcomm Serial modem" 只要勾选了上面两项中的任意一项，都会编译usb_wwan.c。所以我觉得在内核外面编译现成的Quectel_Linux_USB_Serial_Option_Driver_V1.0/v5.3.1代码就行了，得到usb_wwan.ko、option.ko和qcserial.ko这三个文件，然后在板子上insmod这三个文件。确保内核menuconfig里面没有勾选上面所说的两个菜单项（或者勾选为M），不然两份代码会有冲突。 insmod usb_wwan.ko insmod option.ko insmod qcserial.ko 内核里面的菜单项勾选为m的话，会在内核目录里面生成ko文件，不用insmod他那里面的ko文件，insmod内核外面单独编译的v5.3.1里面的ko文件就行。

记得修改Quectel_LTE5G_Linux_USB_Driver_V1.0-5/Quectel_Linux_USB_Serial_Option_Driver_V1.0/v5.3.1/drivers/usb/serial/option.c源文件，在

static const struct usb_device_id option_ids[] = {

#if 1 //Added by Quectel

最后面添加{ USB_DEVICE(0x2C7C, 0x6005) },（就是板子lsusb命令里面看到的2c7c后面那个数字）

这样insmod option.ko后才会出现/dev/ttyUSB0和/dev/ttyUSB1两个串口设备。

同样要修改Quectel_LTE5G_Linux_USB_Driver_V1.0-5/Quectel_LinuxAndroid_QMI_WWAN_Driver_V1.1/qmi_wwan_q.c源文件，在

static const struct usb_device_id products[] = {

最后面添加{ QMI_FIXED_RAWIP_INTF(0x2C7C, 0x6005, 4) },

这样insmod qmi_wwan_q.ko后才会出现/dev/cdc-wdm0这个设备文件。

巨大八爪鱼：

没有/dev/cdc-wdm0文件的话，quectel-CM程序无法运行成功。

正常情况下，只要插了USB线，开机后就会有ifconfig usb0接口，IP地址为192.168.43.100，不需要insmod GobiNet.ko。

如果没有usb0接口，说明模块当前所处的模式不对。这个时候即使insmod GobiNet.ko，usb0接口也不会出现。

	巨大八爪鱼：AT+QCFG="usbnet" 是Quectel 系列4G/5G模块（如EC20、RM500、RG200U等）的AT指令，用于配置USB网络接口模式，即指定模块通过USB连接时使用的网络协议标准。‌ ‌指令格式与参数‌ ‌测试命令‌：AT+QCFG=? 可查询支持的参数值，响应中会列出可用的模式。‌ ‌设置命令‌：AT+QCFG="usbnet",<net>，其中 <net> 为模式参数： 0：RMNET 接口（高通标准，通常用于Linux内核驱动）。‌ 1：ECM（ECM 接口，USB设备通信模式，常见于Linux系统）。‌ 2：MBIM（MBIM 接口，微软标准，支持高级功能）。‌ 3：RNDIS（RNDIS 接口，Windows兼容模式，也可在Linux中使用）。‌ ‌响应‌：成功时返回 OK，失败时返回 ERROR；若省略参数（如 AT+QCFG="usbnet"），会返回当前配置状态。‌ ‌配置步骤与注意事项‌ ‌连接与验证‌：通过串口工具（如minicom）连接模块的调试端口（如 /dev/ttyUSB0），发送 AT 测试通信是否正常。‌ ‌设置模式‌：例如，设置为ECM模式（自动拨号常用）：AT+QCFG="usbnet",1。‌ ‌重启生效‌：配置后需重启模块（如发送 AT+CFUN=1,1）使设置生效。‌ ‌系统识别‌：重启后，系统会生成新的网络接口（如 usb0），可通过 ifconfig 或 ip a 查看IP地址分配。‌
	2025-12-23 13:41 回復
	巨大八爪鱼：AT+CFUN=1,1 是AT指令中用于控制模块功能的命令，具体作用是将模块设置为全功能模式并执行重启操作。‌ ‌命令含义‌：AT+CFUN 指令用于设定电话功能水平。参数 1 表示全功能模式，即启用模块的所有功能（如无线通信、SIM卡操作等）；参数 1 作为第二个值，指示执行重启。重启后，模块会重新初始化并进入全功能状态。 ‌典型应用场景‌：该命令常用于模块初始化阶段，以确保所有功能正常启动。‌ 例如，在设备上电或故障恢复时，通过此指令激活模块并重启，以便后续执行其他操作（如查询SIM卡状态或网络注册）。‌ ‌执行注意事项‌：发送此命令后，模块会重启，期间可能需要约 4 秒时间完成初始化。重启后，建议等待片刻再发送后续指令（如查询 IMSI 或信号强度），以避免响应错误。‌此外，确保SIM卡已正确插入且为USIM卡，以避免功能异常。‌

目前，板子开机后，不需要insmod GobiNet.ko，就有usb0网络接口。
GobiNet.ko并没有起到作用，insmod GobiNet.ko也没有匹配到任何设备。

EC200A这个USB设备上面有0-4这五个接口（interface），五个接口的名字分别为：
root@rk3308b-buildroot:/# cat /sys/bus/usb/devices/2-1/2-1:1.0/interface
Mobile RNDIS Network Adapter
root@rk3308b-buildroot:/# cat /sys/bus/usb/devices/2-1/2-1:1.1/interface
Mobile RNDIS Network Adapter
root@rk3308b-buildroot:/# cat /sys/bus/usb/devices/2-1/2-1:1.2/interface
Mobile Diag Interface
root@rk3308b-buildroot:/# cat /sys/bus/usb/devices/2-1/2-1:1.3/interface
Mobile AT Interface
root@rk3308b-buildroot:/# cat /sys/bus/usb/devices/2-1/2-1:1.4/interface
Mobile MODEM Interface
root@rk3308b-buildroot:/#

板子开机后，在没有插入任何模块的情况下，接口0和1匹配的是linux内核自带的Luckfox_Nova_SDK_250430/kernel/drivers/net/usb/rndis_host.c驱动，接口2-4没有匹配驱动。usb0网络接口就是由内核自带的rndis_host.c驱动产生的。

如果想要让GobiNet.ko起作用，就需要修改Quectel_LTE5G_Linux_USB_Driver_V1.0-5/Quectel_LinuxAndroid_GobiNet_Driver_V1.6/GobiUSBNet.c文件，找到static const struct usb_device_id QuecGobiVIDPIDTable，在里面加上GOBI_FIXED_INTF( 0x2c7c, 0x6005 )。
因为static struct driver_info GobiNetInfo里面第1996行data=(1 << 4)，而在第755-761行有下面的代码
   // Verify correct interface (4 for UC20)
   if ( !test_bit(pIntf->cur_altsetting->desc.bInterfaceNumber, &pDev->driver_info->data))
   {
      DBG( "invalid interface %d\n",
           pIntf->cur_altsetting->desc.bInterfaceNumber );
      return -ENODEV;
   }
所以最后GobiUSBNet.ko会匹配上接口4。
在内核外编译GobiNet驱动代码，并将GobiNet.ko上传到板子上。
adb push "\\OCT1158-UBUNTU\oct1158\Documents\Code\C\Quectel_LTE5G_Linux_USB_Driver_V1.0-5\Quectel_LinuxAndroid_GobiNet_Driver_V1.6\GobiNet.ko" /root
在板子上插入GobiNet.ko模块，可以看到又出现了新的usb1接口，这才是GobiUSBNet.ko产生的网络接口。

可以看到，GobiNet.ko确实匹配的是4号接口（Mobile MODEM Interface），产生了usb1网络接口。
linux内核自带的Luckfox_Nova_SDK_250430/kernel/drivers/net/usb/rndis_host.c驱动依然还是匹配接口0-1（Mobile RNDIS Network Adapter），产生的是usb0网络接口。

	巨大八爪鱼：此时，如果再插入usb_wwan.ko和option.ko这两个模块，那么option.ko会匹配上接口2和接口3，产生/dev/ttyUSB0和/dev/ttyUSB1这两个串口设备。现在接口0-4这五个接口都匹配上驱动了。 root@rk3308b-buildroot:/# cd /root root@rk3308b-buildroot:/root# ls GobiNet.ko option.ko usb_wwan.ko root@rk3308b-buildroot:/root# insmod usb_wwan.ko root@rk3308b-buildroot:/root# insmod option.ko [ 1152.021683] usbcore: registered new interface driver option [ 1152.021882] usbserial: USB Serial support registered for GSM modem (1-port) [ 1152.022408] option 2-1:1.2: GSM modem (1-port) converter detected [ 1152.023552] usb 2-1: GSM modem (1-port) converter now attached to ttyUSB0 [ 1152.023994] option 2-1:1.3: GSM modem (1-port) converter detected [ 1152.025428] usb 2-1: GSM modem (1-port) converter now attached to ttyUSB1 root@rk3308b-buildroot:/root# ls -l /sys/bus/usb/devices/2-1/2-1:1.0/driver lrwxrwxrwx 1 root root 0 Jan 1 00:00 /sys/bus/usb/devices/2-1/2-1:1.0/driver -> ../../../../../../bus/usb/drivers/rndis_host root@rk3308b-buildroot:/root# ls -l /sys/bus/usb/devices/2-1/2-1:1.1/driver lrwxrwxrwx 1 root root 0 Jan 1 00:01 /sys/bus/usb/devices/2-1/2-1:1.1/driver -> ../../../../../../bus/usb/drivers/rndis_host root@rk3308b-buildroot:/root# ls -l /sys/bus/usb/devices/2-1/2-1:1.2/driver lrwxrwxrwx 1 root root 0 Jan 1 00:19 /sys/bus/usb/devices/2-1/2-1:1.2/driver -> ../../../../../../bus/usb/drivers/option root@rk3308b-buildroot:/root# ls -l /sys/bus/usb/devices/2-1/2-1:1.3/driver lrwxrwxrwx 1 root root 0 Jan 1 00:19 /sys/bus/usb/devices/2-1/2-1:1.3/driver -> ../../../../../../bus/usb/drivers/option root@rk3308b-buildroot:/root# ls -l /sys/bus/usb/devices/2-1/2-1:1.4/driver lrwxrwxrwx 1 root root 0 Jan 1 00:06 /sys/bus/usb/devices/2-1/2-1:1.4/driver -> ../../../../../../bus/usb/drivers/GobiNet root@rk3308b-buildroot:/root# ls /dev/ttyUSB* /dev/ttyUSB0 /dev/ttyUSB1 root@rk3308b-buildroot:/root#

使用的网络接口是usb0，IP地址是192.168.43.100，用的是linux内核自带的rndis驱动（Luckfox_Nova_SDK_250430/kernel/drivers/net/usb/rndis_host.c）。

设置命令：AT+QNETDEVCTL=<connect_type>[,<CID>[,<URC_switch>]]
AT+QNETDEVCTL=1,1,1是单次手动连接。
AT+QNETDEVCTL=3,1,1是每次上电都自动连接。
AT+QNETDEVCTL=0是断开网络连接。
第二个参数表示PDP上下文索引号，范围为1~7。第三个参数表示是否开启URC上报。

查询命令：AT+QNETDEVCTL?
响应格式：+QNETDEVCTL: <connect_type>,<CID>,<URC_switch>,<PDN_status>
例如+QNETDEVCTL: 3,1,1,1
查询返回的第四个数PDN_status是网卡连接状态。1表示已连接，0表示未连接。

开机后会自动联网同步网络时间，不需要安装ntpdate命令。

理论上，stm32实现一个usb rndis驱动，就可以绑定lwip协议栈驱动4g模块高速上网了，不使用4g模块本身的AT指令TCP和UDP功能。

EC200A和EC200M的区别：

EC200ACNV1-CAT4模块3孔转板QTMHXB0036QD cat4:下行速率：150Mbps,上行速率：50Mbps

EC200MCNLF-CAT1模块3孔转板QTMHXB0037QD cat1:下行速率：10Mbps,上行速率：5Mbps

卖家说了，两款都没有GPS功能。
