# ESP External Connection
This component provides external wireless connectivity(Wi-Fi & Bluetooth) for ESP chips that do not have built-in wireless capabilities. The APIs used by this component are compatible with the Wi-Fi and Bluetooth component APIs in the ESP-IDF.

## Step to enable this component in an example code:
1. Add this component to your project using ```idf.py add-dependency esp-extconn``` command.
2. In the main file of the example, add the following line:
```c
#ifdef CONFIG_ESP_EXT_CONN_ENABLE
#include "esp_extconn.h"
#endif
```
3. In your app_main() function, add the following line as the first line:
```c
#ifdef CONFIG_ESP_EXT_CONN_ENABLE
esp_extconn_config_t config = ESP_EXTCONN_CONFIG_DEFAULT();
esp_extconn_init(&config);
#endif
```
4. Using esp_wifi components like built-in wireless chips :)
