# Console command ping
The component provides a console where the 'ping' command can be executed.
## API
### Steps to enable console in an example code:
1. Add this component to your project using ```idf.py add-dependency``` command.
2. In the main file of the example, add the following line:
```c
#include "console_ping.h"
```
3. Ensure esp-netif and NVS flash is initialized and default event loop is created in your app_main():
```c
ESP_ERROR_CHECK(esp_netif_init());
ESP_ERROR_CHECK(esp_event_loop_create_default());
esp_err_t ret = nvs_flash_init(); //Initialize NVS
if (ret == ESP_ERR_NVS_NO_FREE_PAGES || ret == ESP_ERR_NVS_NEW_VERSION_FOUND) {
ESP_ERROR_CHECK(nvs_flash_erase());
ret = nvs_flash_init();
}
ESP_ERROR_CHECK(ret);
```
4. In your app_main() function, add the following line as the last line:
```c
ESP_ERROR_CHECK(console_cmd_init()); // Initialize console
// Register all plugin command added to your project
ESP_ERROR_CHECK(console_cmd_all_register());
// To register only ifconfig command skip calling console_cmd_all_register()
ESP_ERROR_CHECK(console_cmd_ping_register());
ESP_ERROR_CHECK(console_cmd_start()); // Start console
```
### Adding a plugin command or component:
To add a plugin command or any component from IDF component manager into your project, simply include an entry within the `idf_component.yml` file.
For more details refer [IDF Component Manager](https://docs.espressif.com/projects/esp-idf/en/latest/esp32/api-guides/tools/idf-component-manager.html)
## Suported command:
### ping:
```
ping [-W <t>] [-i <t>] [-s <n>] [-c <n>] [-Q <n>] [-T <n>] <host>
send ICMP ECHO_REQUEST to network hosts
-W, --timeout=<t> Time to wait for a response, in seconds
-i, --interval=<t> Wait interval seconds between sending each packet
-s, --size=<n> Specify the number of data bytes to be sent
-c, --count=<n> Stop after sending count packets
-Q, --tos=<n> Set Type of Service related bits in IP datagrams
-T, --ttl=<n> Set Time to Live related bits in IP datagrams
<host> Host address
```
