Simple Passkey agent example

A simple passkey agent, invoke with arbitrary MAC/PIN pairs, i.e like 00:01:02:03:04:05/1234

import dbus
import dbus.glib
import dbus.service
import gobject
import sys

class PasskeyAgent(dbus.service.Object):
    def __init__(self, path, keystore):
        dbus.service.Object.__init__(self, dbus.SystemBus(), path)
        self.keystore = keystore

    @dbus.service.method(dbus_interface='org.bluez.PasskeyAgent',
                         in_signature='ssb', out_signature='s')
    def Request(self, path, address, numeric):
        try:
            pin = self.keystore[address]
            print "Request",path,address,numeric,"OK"
            return pin
        except:
            print "Request",path,address,numeric,"failed"
            return ""

if __name__ == "__main__":
    keystore = {}
    for arg in sys.argv:
        addr, pin = arg.split("/")
        keystore[addr] = pin
    PATH = '/my/PasskeyAgent'
    bus = dbus.SystemBus();
    handler = PasskeyAgent(PATH, keystore)
    adapter = bus.get_object('org.bluez', '/org/bluez/hci0')
    sec = dbus.Interface(adapter, 'org.bluez.Security')
    sec.RegisterDefaultPasskeyAgent(PATH)
    main_loop = gobject.MainLoop()
    main_loop.run()

Gtk Passkey agent example

Just run this and when time comes dialog will be shown.

import dbus
import dbus.glib
import dbus.service
import gobject
import sys
import gtk

def pin_entry(address):
        # build dialog
        dialog = gtk.Dialog("New bluetooth connection", None, gtk.DIALOG_MODAL,
                        (gtk.STOCK_CANCEL, gtk.RESPONSE_REJECT, gtk.STOCK_OK, gtk.RESPONSE_ACCEPT))
        dialog.set_default_response(gtk.RESPONSE_ACCEPT)
        dialog.set_position(gtk.WIN_POS_CENTER)

        # tabulka
        table = gtk.Table(2, 2, False)
        dialog.vbox.pack_start(table)
        table.show()

        # entry
        entry = gtk.Entry()
        entry.set_activates_default(True)
        table.attach(entry, 1, 2, 1, 2, gtk.EXPAND|gtk.FILL, gtk.EXPAND|gtk.FILL, 10, 2)
        entry.show()

        # icon
        icon = gtk.Image()
        icon.set_from_stock(gtk.STOCK_DIALOG_AUTHENTICATION, gtk.ICON_SIZE_DIALOG)
        table.attach(icon, 0, 1, 0, 2, gtk.FILL, gtk.FILL, 12, 12)
        icon.show()

        # label
        label = gtk.Label("New bluetooth connection to " + address + "\nPlease enter PIN:")
        label.set_alignment(0, 1)
        table.attach(label, 1, 2, 0, 1, gtk.EXPAND|gtk.FILL, gtk.EXPAND|gtk.FILL, 10, 2)
        label.show()
        
        # run dialog
        if dialog.run() == gtk.RESPONSE_ACCEPT:
                pin = entry.get_text()
        else:
                pin = ""
        dialog.destroy()
        return pin


class PasskeyAgent(dbus.service.Object):
        def __init__(self, path):
                dbus.service.Object.__init__(self, dbus.SystemBus(), path)

        @dbus.service.method(dbus_interface='org.bluez.PasskeyAgent',
                                                 in_signature='ssb', out_signature='s')

        def Request(self, path, address, numeric):
                try:
                        pin = pin_entry(address)
                        return pin
                except:
                        return ""

if __name__ == "__main__":
        PATH = '/my/PasskeyAgent'
        bus = dbus.SystemBus();
        handler = PasskeyAgent(PATH)
        adapter = bus.get_object('org.bluez', '/org/bluez/hci0')
        sec = dbus.Interface(adapter, 'org.bluez.Security')
        sec.RegisterDefaultPasskeyAgent(PATH)
        main_loop = gobject.MainLoop()
        main_loop.run()

TODO

• Show the name of the remote device (and not just its address)
• Rewrite Gtk Passkey Agent to C, because it uses a lot of memory (and does almost nothing)
