rndis error (AEGHB-1328) #619
Description
Answers checklist.
- I have read the documentation ESP-IDF Programming Guide and the issue is not addressed there.
- I have updated my IDF branch (master or release) to the latest version and checked that the issue is present there.
- I have searched the issue tracker for a similar issue and not found a similar issue.
IDF version.
5.4.0
Espressif SoC revision.
esp32s3n8r8
Operating System used.
Windows
How did you build your project?
VS Code IDE
If you are using Windows, please specify command line type.
None
Development Kit.
esp32s3n8r8
Power Supply used.
USB
What is the expected behavior?
ESP32-S3 连接EC801E 4G 网卡，并开始 softAP，手机连接 softAP 进行网络测速: 上行(Mbps) 5.8 下行(Mbps) 7.9
What is the actual behavior?
usb_rndis_4g_module 示例运行过程中，虽然4g模块成功拨号获取了ip，AP热点也能正常被手机连接。但是在手机使用网络的途中ping task返回经常出现timeout，日志打印“E (12635) usbh_rndis: Error rndis packet message”，而手机那边的网速也只有200KB/s。这是为什么呢？
