## Using Wi-Fi connection with ESP32P4
|
||||
|
||||
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
|
||||
|
||||
In order to secure the physical connection between the ESP32-P4 (master) and the slave device, it is necessary to set certificates and keys for each side.
|
||||
To bootstrap this step, you can use one-time generated self-signed RSA keys and certificates running:
|
||||
```
|
||||
./managed_components/espressif__esp_wifi_remote/examples/test_certs/generate_test_certs.sh espressif.local
|
||||
```
|
||||
|
||||
### Configure the slave project
|
||||
|
||||
It is recommended to create a new project from `esp_wifi_remote` component's example with
|
||||
```
|
||||
idf.py create-project-from-example "espressif/esp_wifi_remote:server"
|
||||
```
|
||||
but you can also build and flash the slave project directly from the `managed_components` directory using:
|
||||
```
|
||||
idf.py -C managed_components/espressif__esp_wifi_remote/examples/server/ -B build_slave
|
||||
```
|
||||
|
||||
Please follow these steps to setup the slave application:
|
||||
* `idf.py set-target` -- choose the slave target (must support Wi-Fi)
|
||||
* `idf.py menuconfig` -- configure the physical connection and verification details:
|
||||
- `CONFIG_ESP_WIFI_REMOTE_EPPP_CLIENT_CA` -- CA for verifying ESP32-P4 application
|
||||
- `CONFIG_ESP_WIFI_REMOTE_EPPP_SERVER_CRT` -- slave's certificate
|
||||
- `CONFIG_ESP_WIFI_REMOTE_EPPP_SERVER_KEY` -- slave's private key
|
||||
* `idf.py build flash monitor`
|
||||
|
||||
### Configure the master project (ESP32-P4)
|
||||
|
||||
similarly to the slave project, we have to configure
|
||||
* the physical connection
|
||||
* the verification
|
||||
- `CONFIG_ESP_WIFI_REMOTE_EPPP_SERVER_CA` -- CA for verifying the slave application
|
||||
- `CONFIG_ESP_WIFI_REMOTE_EPPP_CLIENT_CRT` -- our own certificate
|
||||
- `CONFIG_ESP_WIFI_REMOTE_EPPP_CLIENT_KEY` -- our own private key
|
||||
|
||||
After project configuration, you build and flash the board with
|
||||
```
|
||||
idf.py build flash monitor
|
||||
```
|
||||
|
||||
