Bluetooth Device Scanning
by Chris Blunt 22 Oct '04

22 Oct '04

site_archiver(a)lists.apple.com Delivered-To: bluetooth-dev(a)lists.apple.com User-agent: Microsoft-Entourage/11.1.0.040913 Hi, I am just getting started with Cocoa-ObjectiveC and Bluetooth in order to complete a University assignment. This assignment basically needs to scan for Bluetooth devices in range, in much the same way as the standard device browser does, but display the list of devices in a text box (or list box, etc). Can this be done? Or can the results of the search from the standard device browser be returned as an array which the code of the program can then access (i.e. So 1 device is not returned, but all devices). Additionally, is this possible in Java, which I am more familiar with than ObjC?

All you need to do is subclass OBEXSession at a few places to open/close connections, and send and receive data. See OBEXSession.h for details - it's all there. Someone has implemented OBEX over IrDA using our stuff, so it should be possible. If not, let us know! bubba _______________________________________________ Do not post admin requests to the list.

The phone is the SyncML client. ;-) The other way around than in IrDA IrMC Level 4. BTW this is not a newbie question - it is quite an advanced OBEX question. You have understood a lot already!

For the Nokia 7610 you have to connect to the "Client SYNCML" Bluetooth profile. Only this profile will allow SyncML over OBEX - do not ask me why Nokia made it this way. For further reading this should be quite complete: http://discussion.forum.nokia.com/forum/showthread.php?threadid=44303 I have done the same here on my Nokia 6820 but I never played with Apple's OBEX implementation because I have my own. I wouldn't even recommend Apple's version - as far as I know it is tight to Bluetooth only - correct me here if I am wrong. Anyway the Nokia has implemented a separate OBEX server only for SyncML (they seem to have to much man power) but this one is very very buggy at least here in my Nokia 6820. It does not follow most OBEX recommendations and even rejects most things with a reboot of the phone. A basic OBEX implementation is written quite fast - so if you fail go for your own implementation which you can tweak for the Nokia SyncML over OBEX server. I wonder why are you going for a SyncML over OBEX implementation. I am quite sure Apple iSync will support SyncML 1.1.2 over OBEX quite soon (my estimate is around Christmas). As 100% direct competitor your product won't be accepted anymore. Bubba Giles wrote at Mon, 27 Sep 2004 09:56:00 -0700 >> SYNCML-SYNC > The example value for the Target header can be IRMC-SYNC¹ to indicate the > IrMC synchronization service. The Nokia 7610 has Open Mobile Alliance's SyncML Data Synchronization version 1.1.2 over OBEX which must be called via the "SYNCML-SYNC" UUID in the OBEX Connect Target header. It is not an official Bluetooth SIG profile but this is specified within SyncML itself. The Nokia 7610 does not have IrMC over Bluetooth nor does it have SyncML over mRouter which is used by Apple iSync for other (older) Symbian OS mobile phones.

I have seen worse specifications. These two documents have a lot of examples which even are correct. The rest of SyncML is terrible to read and is buggy. =( _______________________________________________ Do not post admin requests to the list. They will be ignored.
