Entering the PIN of a device?

Entering the PIN of a device?

[Fabrice DELENTE]

Hello.

I can't find a way to pair my wiimote with my computer.

I started simple-agent, and tried an rfcomm connection with

# rfcomm connect 1 $WIIMOTE

but I didn't get the prompt for the PIN key to establish the connection.

Is there a file or database somewhere where I can enter this number
manually, saving me some trouble?

I am on Slackware Linux, so I have no access to Gnome or KDE tools to
set up my Bluetooth connections. I succeded with pairing and sharing
files with my cell phone, but not with the wiimote; I have trouble
with a wireless headzset too...

Thanks.

The Wii Remote does not support RFCOMM connections. What are you
trying to do here? Furthermore, the Wii Remote expects a fixed PIN
which is generated by BlueZ automatically for you.

You cannot share files with the Wii Remote. It simply does not support
this. The Wii Remote can only be used as input device. There is a
kernel driver which supports that.

Sorry, I thought the CC to linux-bluetooth was enough!

Ok, I'll look into docs about L2CAP.

Thanks for the info.

My trouble is that when I start simple-agent and then push 1+2 to pair
the wiimote with my laptop, simple-agent doesn't ask for the
PIN... should it happens automagically?

I have grepped the files in /var/lib/bluetooth, I have found my mote
BT address in the files but nothing clearly linked to the PIN key. I
read on wiimote-brew that it was the mote BT address in binary form?

Thanks again! :^)

There was no CC ;) CC is enough of course.

No, don't! The user shouldn't care what protocols are used. I just wanted to
notify you that using rfcomm won't work here.

This is exactly what should happen, yes. No PIN as BlueZ generates it for you.

Did the device show up in /sys/bus/hid/devices ? Did you check dmesg? I think
you got the device connected successfully, it just doesn't do anything useful
without configuration ;)

> Thanks again! :^)

You may also want to have a look at
https://wiki.archlinux.org/index.php/XWiimote
This is a short summary of the current state of the xwiimote drivers.
The user-space
part is still under development so you might want to look at cwiid instead.

Cheers

Strange, mutt showed me a CC though...

Ok, ok, won't do :^)

I guess it hasn't, because when I try simple-agent hci0 $WIIMOTE, it
asks for a PIN?

Well nothing showed in /sys/bus/hid/devices, nor in dmesg. The only
thing I had was in /var/log/messages, after trying the simple-agent
hci0 $WIIMOTE thing:

Feb 14 19:11:11 slick dbus-daemon: [system] Rejected send message, 0 matched rules; type="method_return", sender=":1.65" (uid=0 pid=17775 comm="/usr/bin/python) interface="(unset)" member="(unset)" error name="(unset)" requested_reply=0 destination=":1.9" (uid=0 pid=1930 comm="/usr/sbin/bluetoothd))

Will do. I thought cwiid was abandonned, and replaced by the kernel
driver?

Thanks again!

My tests have been disappointing, I have the wiimote plugin in
bluetoothd (the grep for wiimote in bluetoothd shows a match), but
there is no auto-pairing...

If I have bluetoothd running, and I press 1+2 (or the red button),
nothing shows in dmesg, nor in /sys/bus/hid/devices...

If I press 1+2 and start simple-agent hci0 $WIIMOTE, I get a message
asking for the PIN, but I can't type it (I must type in the wiimote BT
addr in string form, right?)

I modified simple-agent with a bit of python to return the address in
UTF-8 form:

def RequestPinCode(self, device):
    print "RequestPinCode (%s)" % (device)
    wiimote_address_bytes = os.environ["WIIMOTE"].split(":")
    n = ""
    for i in range(len(wiimote_address_bytes)-1, -1, -1):
    	if int(wiimote_address_bytes[i], 16) == 0:
           break
	n += chr(int(wiimote_address_bytes[i], 16))
    return unicode(n, "utf-8")

but I still have an error:

# ./wiimote-agent hci0 $WIIMOTE
RequestPinCode (/org/bluez/5122/hci0/dev_00_1F_C5_1B_3A_B1)
Creating device failed: org.bluez.Error.AuthenticationRejected: Authentication Rejected

Well... I'll try again after a good night sleep :^)

What? One mail earlier you said you are *not* asked for the PIN? If it
asks for the PIN then your Wii Remote isn't detected as a Wii Remote.
You cannot type the PIN as the PIN contains binary-0 characters which
cannot be entered here.

What do you find in these files? Especially the
/var/lib/bluetooth/<bt>/did files are interesting.

Gnah, that doesn't work. You cannot send the binary PIN via dbus to
BlueZ, this is why we provide the wiimote-plugin.

Did you try this patch:
https://github.com/dvdhrm/xwiimote/issues/4#issuecomment-3302615
The Patch 1/2 isn't needed but 2/2 should fix the pairing issues with
any Wii Remote.

Yeah, my bad, I tried simple-agent first without argument, but with
'simple-agent hci0 $WIIMOTE' I get asked for the PIN.

Here is /var/lib/bluetooth/<bt>/did:

# cat did
00:1F:C5:1B:3A:B1 FFFF 0000 0000 0000
00:18:91:D0:7A:24 FFFF 0000 0000 0000

Ok :^) Didn't know that... too bad it doesn't work :^)

Ok, I'll try that this afternoon.

Thanks again!
