Ping library for ESP32 Arduino core

ESP32Ping

Let the ESP32Ping ping a remote machine.

#Note that this is a port from https://github.com/dancol90/ESP8266Ping With this library an ESP32Ping can ping a remote machine and know if it's reachable. It provide some basic measurements on ping messages (avg response time).

Usage

First, include the library in your sketch along with WiFi library:

#include <WiFi.h>
#include <ESP32Ping.h>

Next, simply call the Ping.ping() function

IPAddress ip (192, 168, 0, 1); // The remote ip to ping
bool ret = Ping.ping(ip);

ret will be true if the remote responded to pings, false if not reachable. The library supports hostname too, just pass a string instead of the ip address:

bool ret = Ping.ping("www.google.com");

Additionally, the function accept a second integer parameter count that specify how many pings has to be sent:

bool ret = Ping.ping(ip_or_host, 10);

After Ping.ping() has been called, the average response time (in milliseconds) can be retrieved with

float avg_time_ms = Ping.averageTime();

Fixed in 1.3

Memory leak bug ( marian-craciunescu#4 )

Fixed in 1.4

averageTime changed from int to float.Expect the code to still work , but you should upgrade

Fixed in 1.5

Fixed counters data. (Any review and testing is welcomed)
