incompatible card support

[oldcity.camper]

Thanks for the recommendations! Experience truly makes a difference. You've touched on some very critical points for me. I revised the code a bit yesterday, and now my goal is to develop a small React Native app using either Bluetooth Classic or Low Energy. Later, I plan to add an HTTP server and integrate it into the caravan system I'm developing. I'm sharing the latest code—it's still a work in progress.

/*Code Begin*/

#include <Arduino.h>
#include "HardwareSerial.h"
#include "BluetoothSerial.h"
#define TX_RX_PIN 17 // Tek hatlı UART için kullanılacak pin
BluetoothSerial SerialBT;




int oldValue = 0;
int newValue = 0;
unsigned long timeNow;
unsigned long timeOld;
unsigned long elapsedTime;
int counter = 0;
bool rxActive = 0;
