Real-time Capable Bluetooth Stack for Embedded Systems
======================================================
IBV has analyzed and tested some existing products of
the existing Bluetooth market. The result was that
we found no solution which is applicable to provide
deterministic behavior for asynchronous data exchange 
in control and real-time systems. The existing solutions 
are rather designed for audio streaming or file transfer.


The key features are:

- Real-time capable packet scheduler guarantees deterministic
  delay times

- Full HCI compliant - therefore running on any compatible
  controller (tested on CSR and Zeevo)

- POSIX compliant (tested on QNX6)

- Big endian and little endian support

- Hardware Protocols: BCSP, H4, H3 in beta state

- UART up to 921 kbaud => for minimized paket delay time

- Extended configuration capabilities

- Extended possibility of timing measurements => for
  optimization tasks

- Transfer modes: Raw ACL, L2CAP

- Optional integration of higher level protocols and 
  class drivers


----------------------------------------------------------------

The stack's principles are already in use and provides
transfer times of about 10 ms (depends on the runtime 
environment).

IBV has deep know-how in the Bluetooth technology and
can guarantee to be a competent and reliable partner
for Bluetooth based control applications - especially 
with real-time requirements.
