我试图将通过蓝牙序列发送的RFID标签号的整数​​值存储到一个数组中,以便读者在传递时识别标签。

while (Genotronex.available() > 2) { 
    int n; 
    for (n =0; n<10 ; n++){  // should read 10 Tags 
        int i; 
        for(i = 0 ; i < 3; i++){ 
            BluetoothData[i] = Genotronex.read(); 
            y[i] = BluetoothData[i] - '0'; // convert data received from BT to integer 

            x[n] = y[0]*100+y[1]*10+y[2]*1; // tag number of 3 digits 
        }
    }
} 
delay(100);// prepare for next data ... 

if(str[0] == x[n])  //if passed tag has the same number sent from BT 
{ 
    Serial.print("Helllo World!\n"); 
    Serial.print(n); 
}

如果您的逻辑是正确的,我发现的唯一错误是x[n]分配在循环内。

for (n =0; n<10 ; n++){  // should read 10 Tags 
    for(i = 0 ; i < 3; i++){ 
        BluetoothData[i] = Genotronex.read(); 
        y[i] = BluetoothData[i] - '0'; // convert data received from BT to integer 
    }
        x[n] = y[0]*100+y[1]*10+y[2]*1; // tag number of 3 digits 
}//end n->for loop

试试这个。
