[Request] N900 Bluetooth Identifier

Hi All,

There is thread over here which has been talking about who has seen fellow N900 users in teh wild.

http://talk.maemo.org/showthread.php...highlight=wild

So we thought it would be cool if someone could create an app that allows us to know if one of the bluetooth devices in the area are an N900.
I'm pretty sure that the bluetooth stack sends manufacture details and some other information other than just he device name.
If this is possible then we could have the following feautres.

When the app is on it could search say every 5 minutes for BT devices if it picks up on an N900 then you coudl get a notification.

I know this might kill battery but it could be cool :-0

so gurus is this possible?

Thanks
Chris

Re: [Request] N900 Bluetooth Identifier

Yeah this could be done if the LAP part of the MAC address of the bluetooth address identifies the N900 device. though the LAP part usually marks the manufacturer, I guess :)

Re: [Request] N900 Bluetooth Identifier

Cool,

I think we are on a new Broadcom chipset.

could a few of you with N900's confirm the LAN part of your BT Mac address is this:

34:7E:39:XX:XX:X

Thanks

HEre is the full list of all codes

But this doesn't narrow down the N900 :-(

now I'm stuck he he he

Re: [Request] N900 Bluetooth Identifier

We probably can't find a pattern here, manufactures use the same LAP across different devices, but if we find out that the N900 only use 2 or 3 different LAPs and no other Nokia model use the same LAPs(doubt that), this project can be easily done.

Mine is: 00-25-D0

Re: [Request] N900 Bluetooth Identifier

Thanks @VDVsx

I've been trying all day to get as many N900 mac LAPS as possible.
I'll keep at this for a week or so and then come back and see if we can get something written up :-)

Thanks Again

Re: [Request] N900 Bluetooth Identifier

Mine is 00:BD:3A.

I am thinking about both sound annunciators, and notifiers like you get when an SMS comes in.

Thinking about this in a way that may possibly be doing violence to the Bluetooth spec, imagine that the N900 announces that is supports the "Maemo_Kin_Finder" services in addition to A2DP. Or is the list of services supported only disclosed after a pairing is successful?

But your idea requires a installation of a app to advertise the new service.

Worth also check the BT MACs of other Nokia devices that you might have(only the first 6 digits), in order to see if is not equal to some posted here. Already checked in my 3 other Nokias and none is equal to the ones posted here so far.

2010-01-21 17:41

Re: [Request] N900 Bluetooth Identifier

Yeah I've check other devices as well and none of mine other than other N900's

I'll gather more N900 codes and then compare them against other devices.

I think we prob looking at around 5 different ones, and I have a feeling they will be different based on where the devices were made for. e.g UK, Spain, USA ect.

but that's a guess so let's see what happens

thanks for the helps guys, if you know any other N900 uses please get them to post, looks like we have 3 different codes so far.

EC:9B:5B as well

MPW	2010-01-22 11:36

Re: [Request] N900 Bluetooth Identifier

EC-9B-5B here in Germany.

in how many different manufactures does nokia produce the n900?

Would definitiv be a funny ap. But as the battery is poor, I've got BT disabled all the time. And your program works only when the bt is set to visible.

I think this is a waste of time, just gave my mac to support you anyway.

Bye

So I imagine it being used if you get on the train just to check for fun, or at a conference or a shopping mall, or pub.

It's just for a fun to be honest, and trying to illustrated another great example of how a normal Maemo user can think of something and then with the help of the community an Application is born :-)

00:bd:3a here. am in canada but it's a model from uk i think (bought via expansys)

originally, this idea sprang from thing like proximity applications
seen at some conferences (you are next to someone interested in the same things as you, etc.)

yes, for fun. but also a neat proof of concept. hoping it can move forward (thx!)

It's a good thing (for this idea at least) that the SDP records are visible.

I understand that it would require the installation of an app that would modify the SDP records. Having installed such an app (and enabled it as a contact method, ala the Skype profile) would indictate willingess to strike up a conversation with an otherwise unknown person.

The curious phone would thus be consuming the power, the open to contact phone only bluetooth standby levels.

Re: [Request] N900 Bluetooth Identifier

HI All,

These are all the various N900 mac LAPs I've collected so far and I guess we can use these for the app to start with and add more if we need too:
34:7E:39
C0:38:F9
00:25:D0
00:BD:3A
EC:9B:5B

I agree that the app shouldn't search all the time, but the you can do a manual search or that you can set it to search every 5-10 minutes or somthing. To be honest I'm happy with manual search to start out with.

now the big question. Who knows how to code for maemo?
I don't even though I am a coder, so would anyone be willing to help mok something up for us?

Re: [Request] N900 Bluetooth Identifier

got the following reply from the Nokia Forums

Quote:

I'm not sure that checking the LAP code is going to work for trying to find N900. There is this list thelist (http://802.15ninja.net/bnapbnap/thelist.php) but it does not help much.

You could trying using SDP to check for the Bluetooth profile you want.
You could try this tool for checking the N900 SDP database.
ViewSDP (http://store.ovi.com/content/24022)

I'm not 100% sure what SDP is ?!?

Re: [Request] N900 Bluetooth Identifier

Just leave the bluetooth name set to Nokia N900. Or if you're feeling a little creative you could add N900 onto whatever it's currently set to.

so the app should just scan for other devices with N900 in the name and if possible verify that the device name contains this string - I have BT always on.

stobbsc

2010-02-09 12:31

Re: [Request] N900 Bluetooth Identifier

Well I was hoping the app could scan for the LAP codes I posted earlier, and if it finds a device with one then you get a message or something.

Also perhaps if someone tries to pair with you can they have one of those lap codes that you get told it's an N900 trying to connect, not sure if that is possible though

2010-02-09 13:12

Re: [Request] N900 Bluetooth Identifier

I changed my bt name as soon as i got my n900, the LAP codes is a good idea. why not incorporate both, as in either. n900 in the name or the 00:BD:3A lap, which seems very common for n900.

stobbsc

2010-02-09 13:15

Re: [Request] N900 Bluetooth Identifier

Thats a good idea. I think I covered most if not all the lap codes earlier.

Re: [Request] N900 Bluetooth Identifier

Example to detect: 00:BD:3A and 00:BD:3B ... (expand with \| as address separator)

Code:

#!/bin/bash 

a=`hcitool scan --class |\ 

awk '/BD Address/ {print substr($3,0,8)}' |\ 

grep '00:BD:3A\|00:BD:3B'`; 

echo $a; 

if [ "$a" ] 

then 

dbus-send --type=method_call \ 

--dest=org.freedesktop.Notifications \ 

/org/freedesktop/Notifications \ 

org.freedesktop.Notifications.SystemNoteDialog \ 

string:'Pizza! N900 here!' uint32:0 string:'OK' 

fi;

Save code to: ~/n900finder.sh
Make executable: chmod 755 ~/n900finder.sh
and add a shortcut on your desktop or execute from xterminal (~/n900finder.sh).

It shows an alert (Pizza) if found, otherwise it does nothing.

You can schedule using cron or add a loop and a sleep to have it running in the background.

Re: [Request] N900 Bluetooth Identifier

wow that seemed pretty straight forward.

I've never coded for Maemo beofre but jsut been reading up about MADDE:http://wiki.maemo.org/MADDE

So I guess I should try MADDE out and use/adapt your code to becoming an app ;-)

Thanks for the starting blocks :-)

robota

2010-02-09 16:29

Re: [Request] N900 Bluetooth Identifier

To test execute:

hcitool scan --class

from your Xterminal on N900, copy a BT address (first 6 digits) and replace 00:BD:3A (line #4) with the LAP you copied. Now the alert should appear if that device is discoverable.

Nicer would be to add a handful of python or perl to incorporate the name of the detected device in the alert ...
