usb_rndis_4g_module not work (AEGHB-1089)

[aiotfactory]

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.

General issue report

I followed the guide to do the test with esp32s3, and the log is as following, it looks the usb is found, but it can not ping the ip address, I have tested to ping different ip addresses, it is the same issue.

Can someone take a look? thanks.

Why are you pinging the address 139.196.106.200?

[aiotfactory]

We just changed this IP to a fake one to prevent the leakage of personal information. We also tested 8.8.8.8 and other IPs, none of which are reachable. Moreover, although we can connect to WiFi via mobile phone, we still can't access the internet.

Are you using the ML307R 4G module? I've tested it and it works fine. From the logs, there doesn't seem to be any major issues.

Try setting these two macros to 2048:

CONFIG_IN_TRANSFER_BUFFER_SIZE=2048
CONFIG_OUT_TRANSFER_BUFFER_SIZE=2048

[aiotfactory]

My specific model is 307R DL. I don't know if yours is the same as this model. Could you give me your purchase link? In addition, how does the RNDIS driver read IMEI, ICCID, and CSQ?

I bought it from Taobao in China, so I'm not sure if it's available to you. IMEI, ICCID, and CSQ are not relevant in RNDIS applications. If you want to retrieve this information, you should open a separate AT command channel to access it. This can be done through UART or another USB interface.

[aiotfactory]

I see that the network interface from RNDIS is named ETH. If we also want to use Ethernet simultaneously, and the Ethernet interface is also named ETH, what should we do if there is a conflict between the two?
