pywpas

A python library to control wpa_supplicant via it’s control socket.

Installation

pip install pywpas

Example

import time
import pywpas
# sock_path below is the default and can be omitted.
ctrl = pywpas.Control(sock_path='/var/run/wpa_supplicant)

# You can get a list of interface names:
interface_names = ctrl.interface_names()
print(interface_names)

# You can iterate over instances of the Interface class:
for interface in ctrl.interfaces:
    print(interface.name)

# You can get a specific Interface instance by name:
interface = ctrl.interface(interface_names[0])
print(interface.status())

# You can scan for networks available on an interface:
interface.scan()
# You might wait a few seconds...
time.sleep(5.0)
scan_results = interface.results()

for network in scan_results:
    print(network.ssid, network.signal_level)

# You can connect to a network (implictly adds a profile):
interface.connect(scan_results[0])
# Write the network to the wpa_supplicant.conf file:
interface.save_config()
# Then disconnect...
interface.disconnect()
# and remove the network:
interface.remove_network(scan_results[0])
# Or remove ALL networks:
interface.remove_networks()
interface.save_config()

# You can also add a profile (without connecting):
interface.add_network(scan_results[0])
# And save it:
interface.save_config()

# You can define a network and connect to it:
network = pywpas.Network(ssid='FOOBAR', ...)
interface.connect(network)
interface.disconnect()

# There is a high-level scan function, it will invoke callback
# with each unique network found during the scan timeout duration:
scan = interface.background_scan(lambda network: print(network.ssid),
                                 timeout=30.0)
time.sleep(5.0)
scan.stop()

wpa_supplicant configuration

You must configure wpa_supplicant to open a control socket. Optionally you can enable config file writing.

ctrl_interface=DIR=/var/run/wpa_supplicant GROUP=nobody
update_config=1

Event with an emtpy configuation (no networks) you can use this library to add networks, connect to networks and save the profiles to the configuration file.

Development

To deploy to PyPI:

git tag <version>
git push --tags

CI will do the rest.

Tests and linting:

make test
make lint
