Arduino和PyBluez之间的蓝牙通信 [英] Bluetooth communication between Arduino and PyBluez

问题描述

我正在尝试使用 Python PyBluez 在 Arduino Uno 板(带有蓝牙屏蔽)和我的 Linux 操作系统之间建立蓝牙通信.

I am trying to establish bluetooth communication between an Arduino Uno board (with a bluetooth shield) and my Linux OS, using Python PyBluez.

我已成功将笔记本电脑与 Uno 配对.我可以连接到开发板，但是开发板无法读取正在发送的数据，也无法发送数据.

I've successfully paired my laptop to the Uno. I'm able to connect to the board, however the board is not reading the data being sent nor is it able to send data.

这是 Arduino 草图

Here is the Arduino Sketch

#include <SoftwareSerial.h>

#define RxD 0    //receive data on digital 0
#define TxD 1 //transmit on digital 1

SoftwareSerial blueToothSerial(RxD, TxD);
int counter = 0;
int incoming;
void setup(void){
  Serial.begin(9600);
  //pinMode(RxD,INPUT);
  //pinMode(TxD,OUTPUT);
  setupBlueToothConnection();
}

void setupBlueToothConnection(){
  blueToothSerial.begin(19200);
  blueToothSerial.print("\r\n+STWMOD=0\r\n"); //set the bluetooth work in slave mode
  blueToothSerial.print("\r\n+STNA=SeeedBTSlave\r\n"); //set the bluetooth name as     "SeeedBTSlave"
  blueToothSerial.print("\r\n+STOAUT=1\r\n"); // Permit Paired device to connect me
  //blueToothSerial.print("\r\n+STAUTO=0\r\n"); // Auto-connection should be forbidden here
  delay(2000); // This delay is required.
  blueToothSerial.print("\r\n+INQ=1\r\n"); //make the slave bluetooth inquirable
  Serial.println("The slave bluetooth is inquirable!");
  delay(2000); // This delay is required.
  blueToothSerial.flush();
} 

void loop(){
  if(blueToothSerial.available())
     Serial.println(blueToothSerial.read());
  blueToothSerial.write('x');
}

还有我的 Python 模块:

And my Python Module:

import bluetooth
import sys
bd_addr = "00:12:10:23:10:18" #itade address

port = 1
sock=bluetooth.BluetoothSocket( bluetooth.RFCOMM )
sock.connect((bd_addr, port))
print 'Connected'
sock.settimeout(1.0)
sock.send("x")
print 'Sent data'

data = sock.recv(1)
print 'received [%s]'%data

sock.close()

我有 Arduino IDE 1.0.4，我的笔记本电脑运行的是 Ubuntu 11.10

I have Arduino IDE 1.0.4, my laptop is running Ubuntu 11.10

推荐答案

你的这一行:

data = sock.recv(1)

可能没有收到足够的字节，所以试试 Tim 发布的这个信息:仅从套接字接收一个字节

may be not receiving enough bytes so try this info posted by Tim: Only receiving one byte from socket
