Question

我开发了通过蓝牙发送数据的Android应用程序。我使用覆盆子接收数据。我已将HC05蓝牙模块连接到覆盆子pi3 GPIO引脚（UART0 Tx，UART0r Rx，3.3v PWR，GND）。我编写了Python代码来显示数据。但是经过一段时间后（收到一些数据后）python显示以下错误：

 File "usr/lib/python2.7/dist-packages/serial/serialposix.py" line 460 in read
    raise SerialException('device reports readiness to read but returned no data(device disconnected?)')
    serial.serialutil.SerialException:device reports readiness to read but returned no data(device disconnected ?)

并与HC05断开连接然后如果我尝试发送它的显示错误

File "usr/lib/python2.7/dist-packages/serial/serialposix.py" line 453 in read 
buf=os.read(self.fd,size-len(read))
 OSError:[Error no 11]Resource Temporarily unavaliable

请有人帮我解决这个问题。

My python code is as below:
import serial
import time

port=serial.Serial("/dev/ttyS0",baudrate=9600)

while True:
        rcv = port.read(2)
        print str(rcv)
