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。
我已成功将笔记本电脑与 Uno 配对。我可以连接到板子,但是板子没有读取正在发送的数据,也无法发送数据。
这是Arduino草图
#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:
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
