SoftwareSerial: write(data)

Description

Prints data to the transmit pin of the software serial port as raw bytes. Works the same as the Serial.write() function.

write() will return the number of bytes written, though reading that number is optional

Example

SoftwareSerial mySerial(6, 7);

void setup()
{
  mySerial.begin(9600);
}

void loop()
{
  mySerial.write(45); // send a byte with the value 45

   int bytesSent = mySerial.write(“hello”); //send the string “hello” and return the length of the string.
}
