I am working on a command-line bluetooth application, and my customer recently asked an intriguing question. He would like to be able to connect multiple bluetooth adapters to a darwin-based system in order to effectively increase the bandwidth available for bluetooth communication. I am writing to see if anybody has tried something similar. It is not clear to me if the Bluetooth API will handle the associated multihoming of multiple bluetooth adapters or not. Any thoughts are appreciated. Regards, -Mike Ellis ========================= Michael F.

We actually are not attempting to consolidate the bandwidth offered by the two adapters. Instead, our application is designed to communicate with lots of individual bluetooth devices. On a per connection basis, the actual bandwidth requirements are quite low. Our intention is to create a central bluetooth server that is capable of managing lots of slow connections. We would like to add the extra adapter to effectively double the number of clients that the server can simultaneously support. So I suppose my question is: "Will Darwin's kernel-level bluetooth support take advantage of the extra bluetooth adapter in order to effectively double the number of bluetooth devices that can be simultaneously supported?" There is nothing in the Bluetooth spec for multiplexing one data stream over two Bluetooth radios, and the API follow the spec pretty closely. You didn't say what you need the extra bandwidth for, and I assume it is not networking. If it is a custom designed device, you can do this, but synchronizing the data between two separate stacks would be up to your software and the device. _______________________________________________ This email sent to site_archiver@lists.apple.com
