To find out the bluetooth port

hcitool inq

Last time, I show how to use pys60 to discover
bluetooth devices. Here's another bluetooth
snippet, but this time it use pybluez (BT on Linux).

import bluetooth

target_name = "My Phone"
target_address = None

nearby_devices = bluetooth.discover_devices()

for bdaddr in nearby_devices:
    if target_name == bluetooth.lookup_name( bdaddr ):
        target_address = bdaddr
        break

if target_address is not None:
    print "found target bluetooth device with address ", target_address
else:
    print "could not find target bluetooth device nearby"

Taken from Albert Huang's exellent pybluez tutorial.

Pys60 has good bluetooth support from the beginning.
However, to discover another device, it require you to
interact with the app, choosing a device from the list.
PDIS has a library that help you list all devices silently.

# need to install these 2 modules from PDIS first
import aosocketnativenew
from aosocket.symbian.bt_device_discoverer import *

def callback(error, devices, cb_param=None):
    for address, name in devices:      
        print "Found: ", name, address
# You can get more data by importing socket and try 
# bt_discover(address) or bt_obex_discover(address)
# see details in official pys60 doc on socket module

lister = BtDeviceLister()
lister.discover_all(callback, None)

I summarize the code above from thejamo's example here.
His code is more complete with error checking.

Python for series 60 enables many fun bluetooth stuff.

from socket import *
a = '00:10:60:ab:25:6f'
bt_obex_discover(a)	# found at port 3
f = u'C:\\Nokia\\Startermonlog.txt'
bt_obex_send_file(a, 3, f)
