Python able to access Wifi?

[nick_santa83]

hi, I've looked through the new Python release notes and noticed that there isn't any modules to access the Wifi. Does this means that there is no way to come up with a program that is able to use the internet using Wifi instead of GPRS? Sorry if my question sounds stupid but I've only been in Python for a while.. Thanks

Neither are there any GPRS modules. Connection will use whatever protocol is defined in the access point definition.

[y.a.k]

You don't access GPRS or WiFi or whatever directly. You just use the standard networking modules (like urllib or socket) and the user will be presented with a list of access points upon connecting.

I found this to be a very handy snippet of code for just that kind of thing:

import sys, socket, urllib

apid = None
#this next line brings up the access point menu
apid = socket.select_access_point()
if not apid:
    sys.exit()
apo = socket.access_point(apid)
socket.set_default_access_point(apo)
apo.start()
try:
    ip = apo.ip()
    print u"Connected to WiFi as %s" % ip
except:
    print u"Failed to connect to WiFi"

#Then you can use urllib as much as you want without the phone bugging you to pick an access point:

url = "http://api.wefeelfine.org:8080/ShowFeelings?display=text&returnfields=sentence&feeling=happy&limit=1"
web = urllib.urlopen(url)
response = web.read()
print response

(borrowed this stuff from my Sydewynder app)

Thanks a lot!

any idea if this is the same for C++ and java or even windows mobile?

[mikejedw]

Not sure. I know some people have had trouble doing things with Java due to security restrictions, like recording sound, that seem to work fine with the Python modules. But I haven't tried this with the WiFi/Internet connections.

In Java on S60 devices the user of the application uses the access point to be used. If the user selects WiFi access point, then Wifi is used. However there is no method/code for MIDlets themselves to select WiFi to be used.

ok. Thanks

Very useful.

How I can disconnect?

How I can disconnect?

Call the access point object's 'stop' method. e.g.

import socket

# Setup AP
apid = socket.select_access_point()
apo = socket.access_point(apid)
socket.set_default_access_point(apo)

# Start connection
apo.start()

# Do whatever
do_my_thing()

# Stop connection
apo.stop()

Thank you aya42!

ok in python 1.4.* but in python 1.9.* how can use wifi?
socket.select_access_point() doesn't exist anymore.

I'm trying to use imap module, but it doesn't works because it doesn't establish a connection...

any help?

Wlantools is what you need.

This should work on 1.4.x and 1.9.x...

import sys
try:
    sys.modules['socket'] = __import__('btsocket')
except ImportError:
    pass
import socket

socket.select_access_point()

Hi.
I am writing an app to control my MPD (Music Player Daemon) with my Nokia E51 by wifi.
There is a generic python client library which uses socket module.

I am using pys60 1.9.7.
Everything is working very well, but I wanted to add powersaving to my app.

Here is code I wrote:

if e32.inactivity() > 120:
	if connected:
		disconnect()
		del client
else:
	if connected == 0:
		client = connect()

connect function:

def connect():
	global ip_serwera
	global connected
	client = mpd.MPDClient()           # create client object
	try:
		client.connect(ip_serwera, 6600)  # connect to ip:6600
		connected = 1
	except:
		change_ip()
	return client

disconnect function:

def disconnect():
	global client
	global connected
	if connected:
		client.close()                     # send the close command
		client.disconnect()                # disconnect from the server
		connected = 0
	return 1

I import the library using code:

sys.path.append("E:\\Python")
import mpd

In the library function close sends "goodbye" to server and disconnect does:

def disconnect(self):
        self._rfile.close()
        self._wfile.close()
        self._sock.close()
        self._reset()

But even after I do disconnect WiFi stays ON and uses battery.

What can I do?

WiFi connections is closed only after I close Python interpreter.
