如何使用arduino uno解码或编码通过HC-05发送的数据？

Question

我尝试使用带有arduino uno的HC-05蓝牙模块发送数据。我在发送和接收数据方面都很成功。但是，接收的数据不是人类可读的。我正在使用pybluez连接到模块。以下是收到的数据：

received: ÿ
received: °■
received: ÿ
received: °
received: ÿ°
received: ÿ°
received: ÿ°
received: ÿ°
received: ÿ°
received: ÿ°

这是我的.ino

#include<SoftwareSerial.h>
SoftwareSerial mySerial(2,3);
void setup(){
    mySerial.begin(9600);
}

void loop(){
   if(mySerial.available())
       mySerial.write(mySerial.read());
}

这是我的.py

# simple inquiry example
import bluetooth
import sys

addr = "20:16:12:05:69:99"
port  = 1

sock = bluetooth.BluetoothSocket(bluetooth.RFCOMM)
sock.connect((addr,port))
print 'connected'
sock.settimeout(15.0)
sock.send('10\r\n')
count = 0
while (count<10):
    data = sock.recv(12)
    print 'received: %s'%data
    sock.send(data)
    count += 1
sock.close()
