I made an App to send 3 numbers( second and minute and hour ) to esp8266 wemos d1 mini and showing in terminal but getting an error 1101.
my arduino code :
#ifdef ESP32

int SecVal = 0;
int MinVal = 0;
int HoueVal = 0;

Serial.write(c);
header += c; // we'll store the entire request in 'header'

('\n' on empty line) which signifies the end of an http request */
/* HTTP headers always start with a response code (e.g. HTTP/1.1 200 OK)

client.println("HTTP/1.1 200 OK");
client.println("Content-type:text/html");

client.println();
