l2cap（113，“没有到主机的路由”）

Question

我使用下面的代码在rapsberry PiZero和蓝牙l2cap协议。我的客户端代码总是给我同样的错误

错误：

Traceback (most recent call last):
File "l2cap-client.py", line 11, in <module>
sock.connect((bd_addr, port))
File "<string>", line 5, in connect
bluetooth.btcommon.BluetoothError: (113, 'No route to host')

服务器代码：

^{pr2}$

客户代码：

import bluetooth
sock=bluetooth.BluetoothSocket(bluetooth.L2CAP)
bd_addr = "00:1B:DC:06:C1:AD"
port = 0X1001
#print(sock.getsockname())
sock.connect((bd_addr, port))
print(sock.getsockname())
sock.send("hello!!")
sock.close()
