You need to acumulate all the characters until newline and then you can send it to Wifi client.

Code: Select all  char buf[64];
  int i = 0;
  if (Serial.available()) {
    int inByte = Serial.read();
    buf[i] = (char)inByte;
    if (inByte == '\r' or inByte == '\n' or i > (sizeof(buf) - 1)) {
      buf[i] = 0;
      i = 0;
      client.println(buf); // here we sent the whole line to the WiFi client
    }


ow wow. I'll try this one. thank you so much Mr. Martinayotte.

ohw. it displays

Soil moisture: 9†þ?

this time, instead of a value at around 94.

Maybe try it at slower baudrate ...

slower baud rate for both esp and arduino? i tried lowering the baud rate of the arduino but still used the 115200 for the esp. doesn't work at all. Does this means i have to flash may esp with a firmware which has a slower baud rate?
