Can people run the following command:

$ tar cf /tmp/bluetooth.tar /var/lib/bluetooth

(ignore the errors that it gives) and send me the /tmp/bluetooth.tar
file. I need samples both from people who have been able to connect to bluetooth keyboards under 51 as well as people who have not. (If you haven't yet posted whether or not you are successful, let me know when you send this file.)

Ok -- please find my /var/lib/bluetooth archive attached. I've tried again this weekend, no success so far. Just out of interest -- what are you looking for?

Best regards, Jan

Re: how to get bluetooth pc105 keyboards to work with N900

What component of the system is exactly responsible for handling HID devices in maemo? Under generic linux, I use hidd --connect <mac_address> to connect a bluetooth keyboard (and after that, I can see the connection using hcitool con), but there is no hidd in maemo, so I wonder what replaces hidd (if anything) there?

Re: how to get bluetooth pc105 keyboards to work with N900

BlueZ 4 uses only one daemon - bluetoothd controlled via D-Bus.

Re: how to get bluetooth pc105 keyboards to work with N900

Actually, I was just editing my original message with the fact that I have been looking around and found that hidd is actually deprecated in favor of input service through dbus, which is probably how it works in maemo.
Since I am not very familiar with dbus, can anyone explain how exactly does it work and what command is used to actually activate the input service and connect HID device (keyboard)?

I have read through this link: http://wiki.bluez.org/wiki/HOWTO/InputDevices , but I'm quite lost when it comes to Dbus :-)

Re: how to get bluetooth pc105 keyboards to work with N900

http://wiki.bluez.org/wiki/Input#InputAPI + http://linux.die.net/man/1/dbus-send

You should be able to figure out the exact command. :)
(I have no device at the moment to try to find it.)

Re: how to get bluetooth pc105 keyboards to work with N900

Thanks, I'll try to figure out :-)

Re: how to get bluetooth pc105 keyboards to work with N900

True, hidd is deprecated, but you do have hcitool at your disposal.

Typically, you would do something like this first:

Code:

Nokia-N900-51-1:~# hcitool scan

Scanning ...

        00:22:98:A9:1F:D1        W980        

        00:1D:4F:A7:71:46        Apple Wireless Keyboard

Then you can create a connection like so:

Code:

Nokia-N900-51-1:~# hcitool cc 00:1D:4F:A7:71:46

It is my understanding that since the latest firmware updated, if you check that connection with:

Code:

Nokia-N900-51-1:~# hcitool con

The result will always be empty:

Code:

Connections:

Now, you can do this while debugging in another terminal with:

Code:

Nokia-N900-51-1:/home/user# hcidump -B -w hci-trace.log

After you try to connect, you can read the log file by issuing this:

Code:

Nokia-N900-51-1:/home/user# hcidump -r hci-trace.log

And then chances are you will see that the bluetooth keyboard actually connects:

Code:

> HCI Event: Connect Complete (0x03) plen 11

but then almost immediately:

Code:

< HCI Command: Disconnect (0x01|0x0006) plen 3

> HCI Event: Command Status (0x0f) plen 4

> HCI Event: Disconn Complete (0x05) plen 4

The question, thus, is what process sends the HCI command "disconnect", and why.

PS: To run hci-dump you will have to install the bluez-hcidump debian package, as per the instructions http://80.248.164.233/Bugs:Stock_ans...n_Fremantle.29

I am unable to install bluez-hcidump... I have downloaded the package but when I try to install it, it says it depends on libbluetooth2 and that one is not available.
When I check which packages are available, I see libbluetooth3, but if I try apt-get install libbluetooth3, it says it needs libbluetooth2 as well so I'm stuck here...
