1 year ago I had the same problem. Depending on the ESP8266 (or ESP12) core version, ping functions do not work. (Other libraries don't work the same) Try removing the board through the Arduino board manager and installing version 3.0.2.
check this. https://github.com/esp8266/Arduino/issues/8555
Additionally, if you are using an iPhone, the wifi will automatically go to sleep after screen is turned off and a certain amount of time passes.
I'm trying to ping my phone in the same network, but the function bool pingip = Ping.ping(remote_ip, 5); returns false In Serial writes: ping 15, timeout 0, total payload 480 bytes, 15511 ms I thing ip is avalaibe but function returns false....
The whole code: bool pingme() { Serial.print("Pinging to ip\n"); bool pingip = Ping.ping(remote_ip, 15); if(pingip) { Serial.println("ping Success!!"); return true; } else { Serial.println("ping Error :("); return false; } }
