9 months ago 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 certain USB 4G modules yet. https://github.com/espressif/esp-iot-solution/tree/usb/add_usb_solutions/examples/usb/host/usb_cdc_4g_module

I use AIR724UG and ESP32-S3 with USB connection. and config as: CONFIG_BRIDGE_MODEM_USB_VID=0x1782 CONFIG_BRIDGE_MODEM_USB_PID=0x4E00 CONFIG_BRIDGE_MODEM_USB_INTERFACE_NUMBER=2
