It is possible to use Wi-Fi connection on targets that do not support native Wi-Fi peripheral. This example demonstrates using `esp_wifi_remote` on ESP32P4 in the test configuration defined as `sdkconfig.ci.p4_wifi`. This configuration requires another ESP target with native Wi-Fi support physically connected to the ESP32-P4.
|
||||
|
||||
### Configure master-slave verification
|
||||
This uses [esp_hosted](https://components.espressif.com/components/espressif/esp_hosted) project by default, please refer to its documentation for more details.
|
||||
Note, that `esp_hosted` library currently transmits Wi-Fi credentials in plain text. In case this is a concern, please choose the `eppp` option in `esp_wifi_remote` configuration menu (`CONFIG_ESP_WIFI_REMOTE_LIBRARY_EPPP=y`) and setup master-slave verification (please see [eppp: Configure master-slave verification](#eppp)).
|
||||
|
||||
### esp-hosted: Configure the slave project
|
||||
|
||||
You first need to build and flash the slave project. It's possible to perform this action directly from the host project, these commands can be used to set the slave target device (for example ESP32C6), build and flash the slave project. You will have to hold the RST button to keep the host device (ESP32-P4) in reset while flashing the slave device.
|
||||
```
|
||||
idf.py -C managed_components/espressif__esp_hosted/slave/ -B build_slave set-target esp32c6
|
||||
idf.py -C managed_components/espressif__esp_hosted/slave/ -B build_slave build flash monitor
|
||||
```
