@ -6,6 +6,20 @@ This example connects to a local broker configured to PSK authentication
## How to use example
### Code prepare
If want to use psk function, maybe need change IDF version beyond v4.1 in `esp_idf_version.h`. Like this :
```
/** Major version number (X.x.x) */
#define ESP_IDF_VERSION_MAJOR 4
/** Minor version number (x.X.x) */
#define ESP_IDF_VERSION_MINOR 2
/** Patch version number (x.x.X) */
#define ESP_IDF_VERSION_PATCH 0
```
This feature is controled by macro `MQTT_SUPPORTED_FEATURE_PSK_AUTHENTICATION`, defined in `mqtt_supported_features.h`.
### Hardware Required
This example can be executed on any ESP32 board, the only required interface is WiFi (or ethernet) to connect to a MQTT
