아두이노, 앱인벤터를 이용해서 아두이노에서 스마트폰으로 센서값을 받아오고, 또한 앱상에서 버튼을 누르면 해당 데이터 값을 아두이노로 보내는 작업를 하고있는데 아두이노에서 센서값을 받아오는부분은 문제없는데 스마트폰에서 아두이노로 값을 보내는 것이 아예 안됩니다..
코딩내에서 메인루프안에
if(btSerial.available()){
modecontrol = btSerial.read();} 부분에서 앱인벤터의 버튼값을 아예 수신하지 못합니다...해당 코드 및 앱인벤터 블록 첨부합니다.아두이노 메가로 작업중입니다.#include // I2C 통신 라이브러리#include // LCD 1602 I2C용 라이브러리#include // 온습도센서 모듈 라이브러리#include//아날로그 핀 설정//먼지, 온도, 조도, 강수#define tempoutpin A8#define tempinpin A9#define dustpin A10#define lightpin A11#define rainpin A12//디지털 핀 설정//리미트, 온습도, led, 모터, 불꽃, 부저, 먼지led, 가스#define firepin 2#define gaspin 3#define DHTPIN 22#define limitopin 25#define limitcpin 26#define dustLEDpin 29#define buzzerpin 30#define led_red_pin 34#define led_green_pin 35#define led_blue_pin 36#define motor_win_pin1 39#define motor_win_pin2 40#define motor_win_speed 7 //PWM핀 사용#define motor_bli_pin1 43#define motor_bli_pin2 44#define motor_bli_speed 6#define BT_TX 18#define BT_RX 19//모듈설정LiquidCrystal_I2C lcd(0x27,16,2);

if(btSerial.available()){
modecontrol = btSerial.read();
Serial.println(modecontrol,HEX); // <--- 추가해서 어떤 값이 들어오는지 체크하세요
}
