I know that one device can manage a few connections simultaneously (at least in theory) but if you want to exceed this number there is no other option than using a second or third device. Or is there?

So, just to clarify: There is absolutely no way in OS X to make use of more than one bluetooth dongle/antenna/HCI at the same time? Even if you access the devices on a low hardware layer and do not use Apple's Bluetooth API? It can be done with Linux, so what's the issue with OS X?

The Apple Bluetooth frameworks support communications with multiple devices, just not communication using more than one dongle/antenna/ HCI. I think the limit of allowable devices is 7 or 8, which is part of the Bluetooth spec iirc.

Hello,

according to some messages in the list archives it is not possible to use more than one bluetooth device at a time with the Bluetooth API.
What I'd like to accomplish is to use multiple Bluetooth USB dongles that are connected to the Mac to send and receive files using OBEX to/from many different devices simultaneously.
e.g. it should be possible to send different files to 3 different mobile phones while receiving files from 2 others and still do a device discovery at the same time.


Since Apple's Bluetooth API seems to be limited to only one bluetooth device I'd like to know if there are any other ways to solve the problem. Is there a way to access the devices on a low- level layer and put a third-party Bluetooth API on top of it?

Any ideas are highly appreciated.

Thanks, Thomas
