Network Access to External Devices

Dear Community,

We are working with a WiFi camera that supports internet access via both Ethernet and WiFi. Our goal is to provide internet connectivity to this camera using the Quectel EC200U module via the USBNET class in ECM mode. However, we have encountered several challenges:

  1. We attempted using a USB-to-Ethernet converter, but it was unsuccessful due to missing drivers (Windows/Linux).
  2. We tested EC200U USBNET in ECM mode with ESP32-S3 TinyUSB, following the official ESP-IDF NCM example. However, this approach did not work since it supports only NCM mode, whereas our EC200U module operates in ECM mode.
  3. We also attempted the ESP-IoT-Solution USB dongle example on ESP32-S3, but this did not yield the desired results.

Additionally, our system uses UART2 for Modbus RS-485 communication, meaning we cannot utilize UART2 for alternative connectivity solutions.

We came across documentation indicating possible ESP8266/ESP32 support for ECM mode, but it appears incomplete when we attempt to integrate it.

Request for Guidance

We seek a reliable approach to provide internet access to the camera from the EC200U module, using either Ethernet or WiFi.

Any insights, alternative solutions, or suggestions on how to achieve this effectively would be greatly appreciated.

Thank you in advance for your support!

hi

EC200U Support usbnet and ESP8266.
If you use usbnet, in the windows environment, you only need to install the driver of the module.
And if you use ESP8266.You need a custom firmware to test.
Please confirm which option you finally choose.

Hi Felix,

Our team has decided that we will use Ethernet W5500. So, we are working on it. We have created the circuit by follow documentation of W5500. Just, I want a confirmation from your end. Is EC200U supports ethernet protocol using W5500 for providing internet to another devices ?

Please provide your concern.

Thank you :slight_smile:

Hi sumeri

yes, EC200U supports W5500, the firmware on the official website supports W5500, please test it, thank you
