# WiFi station to "Wired" interface L2 forwarder
|
|
|
|
(See the README.md file in the upper level 'examples' directory for more information about examples.)
|
|
|
|
This example aims to demonstrate 1-1 bridge using WiFi station and one of these interfaces (so called *wired* in this example)
|
|
- Ethernet (supported for all targets)
|
|
- USB acting as NCM device (supported for ESP32-S2 and ESP32-S3)
|
|
|
|
It also allows for reconfiguring WiFi settings using a virtual network in the Ethernet. The reconfiguration mode is initialized if the WiFi settings are not available, connection fails or manually by long pressing the Boot button (GPIO0).
|
|
It is possible to configure WiFi settings (SSID and password) in a browser on an address `"wifi.settings"` or using unified provisioning.
|
|
|
|
## How to use example
|
|
|
|
This example could be used to *bring* wireless connectivity to devices that support only Ethernet (or USB Ethernet implemented as NCM device).
|
|
This example also supports runtime configuration of WiFi settings by means of a webpage or unified provisioning.
|
|
|
|
|
|
### Hardware Required
|
|
|
|
Any board with either Ethernet of USB-OTG supported.
|
|
|
|
### Configure the project
|
|
|
|
Open the project configuration menu (`idf.py menuconfig`).
|
|
|
|
In the `Example Configuration` menu choose the provisioning method:
|
|
* `EXAMPLE_WIFI_CONFIGURATION_MANUAL` for manual configuration using a webpage
|
|
* `EXAMPLE_WIFI_CONFIGURATION_PROVISIONING` for standard provisioning over the virtual USB network
|
|
|
|
To provision the device using IDF provisioning tools (if `EXAMPLE_WIFI_CONFIGURATION_PROVISIONING` is selected) you can use idf provisioning utility with transport set to `softap`:
|
|
```bash
|
|
esp-idf/tools/esp_prov$ python esp_prov.py --transport httpd ...
|
|
```
|
|
Please refer to the provisioning documentation and `esp_prov` script [documentation](../../../tools/esp_prov/README.md) for more details.
|
|
|
|
### Build, Flash, and Run
|
|
|
|
Build the project and flash it to the board, then run monitor tool to view serial output:
|
|
|
|
```
|
|
idf.py -p PORT build flash monitor
|
|
```
|
|
|
|
(Replace PORT with the name of the serial port to use.)
|
|
|
|
(To exit the serial monitor, type ``Ctrl-]``.)
|
|
|
|
See the Getting Started Guide for full steps to configure and use ESP-IDF to build projects.
|
|
|
|
## Example Output
|
|
|
|
After the flashing you should see the output at idf monitor:
|
|
|
|
(note that this is the output of USB configuration)
|
