ping()
Açıklama
Ağdaki uzak bir aygıta ping atın.
Sözdizimi
WiFi .ping (ip);
WiFi .ping (ip, ttl);
WiFi .ping (ana bilgisayar);
WiFi .ping (ana bilgisayar, ttl);
Parametreler
ip : ping yapılacak IP adresi (4 baytlık dizi)
host : ping yapılacak ana bilgisayar (dize)
ttl : Yaşam süresi (isteğe bağlı, varsayılan 128'dir). İsteğin yönlendirilebileceği maksimum yönlendirici sayısı.
İadeler
Ping başarılı olduğunda WL_PING_SUCCESS
Hedef (IP veya ana bilgisayara erişilemiyorsa) WL_PING_DEST_UNREACHABLE
Ping zaman aşımına uğradığında WL_PING_TIMEOUT
Ana bilgisayar DNS üzerinden çözümlenemediğinde WL_PING_UNKNOWN_HOST
Bir hata oluştuğunda WL_PING_ERROR
Misal
/*
This example connects to a encrypted WiFi network (WPA/WPA2).
Then it prints the MAC address of the board,
the IP address obtained, and other network details.
Then it continuously pings given host specified by IP Address or name.
