I'm trying to connect to custom bluetooth device with sockets using python. I use pybluez to find device and get it's address. Current code looks like this:
import bluetooth, subprocess
import socket
class BCI(object):
"""
Bluetooth Connection to BCI
"""
socket_ = None
bluetooth_address = None
connected = False
port = 0x005
dev_name = None
cmds = {}
status = {
0: 'ok',
1: 'communication timeout',
3: 'checksum error',
4: 'unknown command',
5: 'invalid access level',
8: 'hardware error',
10: 'device not ready',
}
def __init__(self, *args, **kwargs):
self.bluetooth_address = kwargs.get("bluetooth_address", None)
if self.bluetooth_address is None:
self.find()
def connect(self):
try:
self.socket_ = socket.socket(socket.AF_BLUETOOTH, socket.SOCK_STREAM, socket.BTPROTO_RFCOMM)
#self.socket_ = socket.socket(socket.AF_BLUETOOTH, socket.SOCK_SEQPACKET, socket.BTPROTO_L2CAP)
self.socket_.connect((self.bluetooth_address, self.port))
self.connected = True
except:
self.socket_.close()
self.connected = False
raise ConnectionError
def find(self):
dev = self.__class__.__name__
print('Searching for ' + dev)
nearby_devices = bluetooth.discover_devices(duration=8, lookup_names=True, flush_cache=True)
for index, val in enumerate(nearby_devices):
addr, name = val
if dev in name.upper():
self.dev_name = name
self.bluetooth_address = addr
print('Found BCI: ' + name + ' @', self.bluetooth_address)
return
def find_bluetooth_services(self):
services = bluetooth.find_service(address=self.bluetooth_address)
if len(services) > 0:
print("found %d services on %s" % (len(services), self.bluetooth_address))
print(services)
else:
print("no services found")
def close(self):
self.socket_.close()
if __name__ == "__main__":
try:
device = BCI()
except:
print('No devices BCI found')
try:
print("Trying to connect with "+ device.__class__.__name__)
device.connect()
except ConnectionError:
print ('Can\'t connect with ' + device.__class__.__name__)
'''
try:
device.find_bluetooth_services()
except:
print("Some problem occured")
'''
if device.connected:
print('Connected {}'.format(device.dev_name)+ device.__class__.__name__ +' @', device.bluetooth_address)
It founds device and tries to connect (terminal output):
Searching for BCI Found BCI: BCI-2016-SN005 @ 00:80:E1:BE:EE:F1 Trying to connect with BCI
,so there is a notification from settings demanding approve the connection with the some number code. After I approve connection, this gets out (terminal output):
Can't connect with BCI
What am I doing wrong?
I tried to use connect_ex() instead of connect() and got this error code 10065, but couldn't find out what it means in context of bluetooth
