Will that solve your problem, or is there another issue? - Eric _______________________________________________ bluetooth-dev mailing list | bluetooth-dev(a)lists.apple.com Help/Unsubscribe/Archives: http://www.lists.apple.com/mailman/listinfo/bluetooth-dev Do not post admin requests to the list.

Switching master/slave roles

Dropped data packets with an RFCOMM connection
by Keith Phu 14 May '03

14 May '03

Hi, I'm using an RFCOMM connection to transmit data from one powerbook to another. The application on the transmitting powerbook repeatedly uses the 'write:length:sleep' function to transmit a block of data (of about 10 bytes) to the other receiving powerbook every 10 ms. After running for about 1 minute (that's a total of 6000 blocks transmitted), a small number of blocks will not have arrived at the receiver. The transmitter will will have successfully (as returned by 'write:length:sleep') transmitted 6000 blocks, but the receiver will only have received say 5997 blocks. Some of the blocks have gone missing. Does anyone have an idea of where these missing blocks have gone? And a way to make the RFCOMM connection more reliable (without needing to add my own error correction algorithm to my application)? Can we not assume that an RFCOMM connection provides 100% reliability in a typical situation?

Spec., Documentation, OpenSource
by Marcel Weiher 14 May '03

14 May '03

Hi folks, is there some kind of overview over which parts of the various bluetooth(-related) specs are covered in the current implementation? And better yet, by which part of the implementation? This would be extremely helpful, for example in determining if and how to implement other specs that build on the lower levels, and possibly even in using existing OpenSource implementations.

Both the P800 and the Nokia 3650 are not supported by Apple's iSync. For use as an GPRS modem (bluetooth) there both supported. Since Apple iSync only supports SonyErricson phones what would be the best choice. But if you want a good phone I would go for a Nokia. Maybe it's smart to wait until Apple releases iSync 1.1 http://www.thinksecret.com/news/isync112.html On dinsdag, mei 13, 2003, at 05:29 Europe/Amsterdam, Patricio Rojas wrote: Does anyone know which cellphone work better with the jaguar OS, the P800 sonyericsson or the Nokia 3650...??

You should not experience this problem if you use the MS Bluetooth receiver. WIth it, and the mouse acceleration set to full, mine works beautifully. However, using any other Bluetooth receiver I have problems. I do not know if this is a bug. It seems to be more of a hardware problem.

I saw a friend last night who had just bought an MS BT mouse and keyboard - and it was doing exactly as you said - I was quite surprised. BT HID profile support is very new in OS X - so I assume it is not the hardware's fault. Diggory.
