Ping is a useful network utility used to test if a remote host is reachable on the IP network. It measures the round-trip time for messages sent from the source host to a destination target that are echoed back to the source.
This example implements a simple ping command line util based on the [console component](https://docs.espressif.com/projects/esp-idf/en/latest/api-guides/console.html).
**Notes:** Currently this example only supports IPv4.
## How to use example
### Hardware Required
This example should be able to run on any commonly available ESP32 development board.
### Configure the project
```
idf.py menuconfig
```
In the `Example Connection Configuration` menu:
* Choose the network interface (Wi-Fi or Ethernet) used by this example under `Connect using`.
* If Wi-Fi interface is selected, you also have to set:
* Wi-Fi SSID and Wi-Fi password that your board will connect to.
* If Ethernet interface is selected, you also have to set:
* Select Ethernet type under `Ethernet Type`, for example, `Internal EMAC` or `SPI Ethernet Module`.
* Select Ethernet PHY chip model under `Ethernet PHY Device`, for example, `IP101`.
* You might also have to set other Ethernet driver specific parameters under `Component Config > Ethernet`, for example, EMAC Clock mode, GPIO used by SMI, and etc.
### Build and Flash
Build the project and flash it to the board, then run monitor tool to view serial output:
```
idf.py -p PORT flash monitor
```
(Replace PORT with the name of the serial port to use.)
(To exit the serial monitor, type ``Ctrl-]``.)
See the Getting Started Guide for full steps to configure and use ESP-IDF to build projects.
## Example Output
* Run `help` to get manual of all supported commands.
