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。

【串口AT指令测试程序】

#include <fcntl.h>
#include <stdio.h>
#include <string.h>
#include <unistd.h>

void send_atcmd(int fd, const char *cmd)
{
   char resp[100];
   int ret;

   printf("Command: %s\n", cmd);
   write(fd, cmd, strlen(cmd));
   write(fd, "\r\n", 2);
   ret = read(fd, resp, sizeof(resp) - 1);
   resp[ret] = '\0';
   if (ret >= 1 && resp[ret - 1] == '\n')
        resp[ret - 1] = '\0';
   printf("Response: %s (size=%d)\n", resp, ret);
}

int main()
{
   int fd;

   fd = open("/dev/ttyUSB1", O_RDWR);
   if (fd == -1)
   {
        perror("open() failed");
        return -1;
   }
   send_atcmd(fd, "AT");
   close(fd);
   return 0;
}
【程序运行结果】

root@rk3308b-buildroot:/root# ./atcmd_test
Command: AT
Response: AT (size=3)
root@rk3308b-buildroot:/root#
