我正在嘗試構建一個簡單的藍牙客戶端/服務器,其中我的Raspberry Pi是服務器,而我的筆記本電腦是客戶端。嘗試連接到藍牙服務器時拒絕連接
這是(我的樹莓派運行)的服務器代碼:
#!/usr/bin/python
# -*- coding: utf-8
import wifi, bluetooth
uuid="1e0ca4ea-299d-4335-93eb-27fcfe7fa848"
print "Setting up Bluetooth socket"
try:
sock = bluetooth.BluetoothSocket(bluetooth.RFCOMM)
sock.bind(("", 0))
sock.listen(1)
except IOError as e:
print str(e)
print "Registering service"
try:
bluetooth.advertise_service(sock, "MyService", uuid)
while True:
print "Waiting for connection..."
client_sock,address = sock.accept()
print "Accepted connection from {0}".format(address)
data = client_sock.recv(1024)
print "Received data: {0}".format(data)
print "Closing client socket."
client_sock.close()
except IOError as e:
print str(e)
這似乎是工作,腳本運行,並與Waiting for connection...
塊。
然後,我的客戶端代碼:
#!/usr/bin/python
# -*- coding: utf-8
import bluetooth, time
mac = "00:15:83:E5:E2:46"
uuid = "1e0ca4ea-299d-4335-93eb-27fcfe7fa848"
service = []
retry = 1
while len(service) == 0:
print "Looking for service on {0}, try {1}".format(mac, retry)
service = bluetooth.find_service(address=mac, uuid=uuid)
retry = retry + 1
time.sleep(1)
if len(service) == 1:
service = service[0]
print "Service found. Name={0}".format(service["name"])
print "Connecting to service."
sock = bluetooth.BluetoothSocket(bluetooth.RFCOMM)
try:
sock.connect((mac, service["port"]))
print "Connected to service on {0} on port {1}".format(mac, service["port"])
except bluetooth.btcommon.BluetoothError as e:
print "Connection failed: {0}".format(e)
elif len(service) == 0:
print "No service found on mac {0}.".format(mac)
else:
print "{0} services found for mac/uuid, ignored.".format(len(service))
而且工作,直到我試圖connect()
到樹莓派。我得到以下錯誤:
Connecting to service.
Connection failed: (111, 'Connection refused')
我試圖連接筆記本到樹莓派(找到它,並說,這是「已連接」),並尋找更多的信息網上,但沒能發現任何東西。
[文檔](HTTPS:// pybluez .googlecode.com/svn/www/docs-0.7/public/bluetooth-module.html#get_available_port)說:'不推薦使用。而不是綁定到端口0。 '。另外,當請求服務時,它說它在端口1上運行。當選擇不同的端口時,我得到一個不同的錯誤。 –
模糊文檔的另一個例子。明確採取了港口的做法。端口1沒有工作。 –
