Thinkpad Bluetooth

DrMikeDuke · 2009-05-24 19:29:49

Hello,

I'm not sure if there is a need for this (being that you can write echo statements)
but I wrote a small C program which turns your bluetooth on and off and loads and unloads
the required modules into/out of the kernel.
It is written for an IBM X31 Thinkpad, but I suspect perhaps it may work just as well on any
lenevo/IBM thinkpad.

If anyones vaugely interested let me know

Will it work on a SL500? This series is based on Ideapad firmware...
But I'll give it a try if it works...:D

Hey,

Glad to see theres some interest! It'd be awesome if you could test that for me.
Im just on my way out at the moment I'll post details later today. Cheers!

Regards,

Mike.

I own a x60s and would love to see what you did. Could you post your code on github or bitbucket?

Hello All,

Sorry Ive been *really* busy these past few. Anyhow. To give you an idea here is a *really* early implementation
of the little program I hacked out. Its not very clean but it works. I am currently testing the modular version of this
program which includes command line checking so you can use the -on -off functions from outside the program, useful
for scripts and so on, which I shall post in the coming week. Please don't think too harshly of my little program its not too often I write C

Edit: Adding in to the next version better checking of file existance.
Can anyone tell me if sys/devices/platform/thinkpad_acpi/bluetooth_enable is a standard location across all thinkpads?
Any additional suggestions or better ways of doing things (no doubt there is) because speaking to others it seems theres no
good tool for doing just this out there atm.

That would be awesome.

And everything seems to work perfectly with my T400.

Thanks!

No it is not. I have a SL500 and this Series is based on Ideapad Firmware but sold as Thinkpad.
See: http://www.thinkwiki.org/wiki/Category:SL_Series

So I installed this driver: http://github.com/tetromino/lenovo-sl-l … ree/master (available in AUR). The path for activating Bluetooth here is /sys/devices/platform/lenovo-sl-laptop/rfkill/rfkill*/state. This may change in future versions according to the dev, see http://linux.derkeiler.com/Mailing-List … 06220.html for further documentation.

So your script won't work for me.
Thanks for sharing anyway.

I had a nifty idea for support of ANY laptop. Lets see how my implementation goes
i'll let this thread age untill I've got something to show you guys and I'll resurect it - Promise.

Ok, cool.:D I look forward to read from you.
