我正在尝试在 Raspbian Linux 上运行一个非常简单的蓝牙服务器。如果有什么不同,我使用的是 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,所以我有点惊讶我没有发现任何关于这个特定问题的提及。这个的客户端版本也可以正常工作。
