[LINUX] Sony PlayStation 3 Blu-ray Disc Remote (PS3 BD) + LIRC + XBMC = SUCCESS
#46
Everything works fine until I'm trying to find the remote controll with
cat /proc/bus/input/devices. It dosen't show ps3 remote. I have no idea what has gone wrong. I'm using Ubunty Jaunty.
Anyone has any idea?

I have no problems with unpairing, only after I pair with my PS3 I need to reconnect it with BlueZ. When does it happen for you?
I tried additional daemons (evrouter and gizmod), they allow you to map a key to a different code. Which works great, except that events which use the new keycode will never arrive because fakehid drops all events for codes it doesn't know about Eek So modifying fakehid, like you did, is the only way I can think of to make all buttons work.

The thing is that input device is not removed after unpairing. Especially if it is unpaired by turning off the remote with holding ps button or when remote gone to standby/lowpower mode.
Moreover, in first case remote generates keypress, and input driver starting to generate key repeats, waiting for key release event. But release never occurs as remote is turned off...
Only when I initiate unpairing from host (blueman f.i.), or remove batteries - input device will be removed, but in several minutes.

Can we detect the low power mode ? Does it send anything to other devices when it does that ?

Here is new "powersaving" patch. It includes all previous modifications.
This patch now is watching for time passed since last keypress event, and disconnecting BT channel on idle. Though, it keeps input device always on, which allows application to receive keypress immediately on pairing event. Before that, application missed keypress pairing event due to new HID creation and delays in evdev for new device recognition. Now, if device is sleeping, you'll notice only one second delay for first pairing keypress.
The point is, that remote is consuming 0.18mA wile paired and 0.03-4 mA while unpaired (sleeping). At least such numbers are shown by my multimeter. %) And it doesn't matter if sleep mode is done explicitly (holding ps) or implicitly by closing connection from host.
Idle timeout is used from input.conf, though in ps3 code it is measured in seconds. If timeout is less then 5(sec) it is set to 300 (5 min). I'm using 15 sec. Sufficient to actively navigate through menus but quickly goes sleeping.

I just ordered a remote and dongle so I should be able to try it out soon. It appears they released 4.49 today so I guess I will try it with that version.

I can confirm the patches work on current git version of BlueZ. Nice work!

I've successfully been able to pair the remote and can see output from irw, but how do I go about configuring lircmap.xml and keymap.xml to do the good stuff? I have no previous experience with lirc, so I'm at a bit of a loss in doing this part.

I've only modified hardware.conf, lircd.conf, lircmap.xml and keymap.xml... is that all that's required?

Yes, if you see key events in irw - remote is working and lircmap is sufficient. If some extra functions required - you can add them to keymap.

Ok, I guess I'll have to take another look tonight to see why XBMC isn't responding. The remote does nothing at all at this point in XBMC, but acts just like it used to on the desktop (like a keyboard's arrow keys).

Check logs (~/.xbmc/temp/xbmc.log), might be your files are rejected due to some typos
Reply

Put this in userdata/advancedsettings.xml to get some useful info about keypresses in your log.

Code:
<displayremotecodes>true</displayremotecodes>
