#include <SoftwareSerial.h>

SoftwareSerial BTserial(10, 11);

void setup() {
    BTserial.begin(9600);
    Serial.begin(9600)
}

void loop() {
    //send data to the nodeJS server
    BTserial.print('1');

    //read the sent data from the nodeJS server
    Serial.println(BTserial.readStringUntil('\n'));
