If you will only use a data forwarding netif, such as softap, it is recommended that you use idf release/4.4

It is recommended that you use idf release/v4.4 first, because idf release/v4.4 has been verified by many customers, and the throughput depends on the baud rate of uart. If you...

This communication rate depends on your uart baud rate, if you need high throughput, it is recommended to use the usb interface

If you only need to implement 4G -> AP, it is recommended that you use this [demo](https://github.com/espressif/esp-iot-solution/tree/usb/add_usb_solutions/examples/usb/host/usb_cdc_4g_module) , Is it because the 4G module has insufficient power supply that the...

The program running here means that the usb host has been initialized and is waiting for the connection of the usb device. If it is not confirmed that the usb...

Thank you for your reminder, the previous logic is not rigorous, S2, S3 should not remove the uart compilation. I'll submit that revision later.

Hi Are you only using **modem** and **softap**, can you try to run this [demo](https://github.com/espressif/esp-iot-solution/tree/usb/add_usb_solutions/examples/usb/host/usb_cdc_4g_module) and follow the [documentation](https://github.com/espressif/esp-iot-solution/blob/usb/add_usb_solutions/examples/usb/host/usb_cdc_4g_module/README.md) above requirements to check whether the configuration is correct.

Hi Please try again after modifying the usb port. menuconfig PATH: Component config → ESP-MODEM → USB CDC endpoint address config Modem USB CDC OUT endpoint address(0x05) Modem USB CDC...

Hi Florian, Do you have any other 4G Cat.1 modules that we have already adapted? You can try the other ones. We will try to find a SIM7600E for testing...

If you intend to use a USB 4G module, I recommend using the following example. The USB host component that the iot-bridge project relies on doesn't provide full support for...
