Question

我正在尝试在Raspbian Linux上运行一个非常简单的蓝牙服务器。如果它有所不同我使用Raspberry Pi 3的蓝牙适配器而不是加密狗。

from bluetooth import *

server_sock=BluetoothSocket( RFCOMM )
server_sock.bind(("",PORT_ANY))
server_sock.listen(1)

port = server_sock.getsockname()[1]

uuid = "94f39d29-7d6d-437d-973b-fba39e49d4ee"

advertise_service( server_sock, "SampleServer",
               service_id = uuid,
               service_classes = [ uuid, SERIAL_PORT_CLASS ],
               profiles = [ SERIAL_PORT_PROFILE ], 
#                   protocols = [ OBEX_UUID ] 
                )

print("Waiting for connection on RFCOMM channel %d" % port)

client_sock, client_info = server_sock.accept()
print("Accepted connection from ", client_info)

try:
    while True:
        data = client_sock.recv(1024)
        if len(data) == 0: break
        print("received [%s]" % data)
except IOError:
    pass

print("disconnected")

client_sock.close()
server_sock.close()
print("all done")

运行时会产生以下错误：

Traceback (most recent call last):
  File "rfcomm-server.py", line 15, in <module>
    profiles = [ SERIAL_PORT_PROFILE ], 
  File "build/bdist.linux-armv7l/egg/bluetooth/bluez.py", line 268, in    advertise_service
bluetooth.btcommon.BluetoothError: error no advertisable device.

我见过很多人使用这个确切的代码，所以我很惊讶我没有发现任何关于这个特定问题的提及。此客户端版本的工作正常。
