希望PC或者手机可以直接使用ESP32和移远模组当作一个路由器使用。
这个板子是合肥墨子号的ESP32的开发板。
我在Ubuntu 上使用IDF。相关环境略。
git clone https://github.com/espressif/esp-iot-solution.git
cd esp-iot-solution/examples/usb/host/usb_cdc_4g_module
idf.py menuconfig
其实修改的就是
sdkconfig 里的这些配置
编译下载到ESP32里。
// 使用普通用户是没有/dev/ttyUSB0 的读写权限的
sudo chmod 777 /dev/ttyUSB0
编译 下载 和监视串口
idf.py -p /dev/ttyUSB0 build flash monitor
默认创建的热点是esp_4g_router，密码是12345678

同样是上面的代码，修改的地方
请问EC800E，怎么修改
EC800K 我应该是设置对了，cdc端口为0
但是他连接ESP32后提示MPS超过了408，这个提示在ESP32S4 ECM的示例中也有

还想问一下 EC200U的0x02 0x07这些值的来源？
通过USB描述信息能看出来吗？
知其然知其所以然
EC800E的AT口是intf 3 ; intf 4 是modem 口。
→ 这里改成0x03 和 0x04.
接口顺序在移远的驱动移植文档里有介绍。
天猫fae说EC800E没有USB描述符，又让买的EC801
一般只要了解一个接口顺序和对应的功能即可，这个USB接口描述符的详细说明除非要做非常底层的USB通信开发才需要。
天猫客户推荐EC801E主要是由于目前主要维护的是EC801E, 方便后续升级。
改成0x03 和 0x04也不可以呢！请问是什么原因呢
重新发下完整的日志。看日志是AT不通。
最好抓个usbtreeview看下USB接口顺序，或者接到Linux上，cat /sys/kernel/debug/usb/devices 看看。
EC800E.txt (24.6 KB)
usbtreeview.txt (9.3 KB)
接口还是应该是0x03 和0x04.
试过了还是不行呢，什么原因呢，EC800E-CN
不是论坛上能解决的啦。
