Analysis of information sources in references of the Wikipedia article "Bluetooth stack" in English language version.
The first steps into supporting Bluetooth with Linux are done by Axis Communications and they released their OpenBT Bluetooth Stack in April 1999. Also IBM released its BlueDrekar which was only available as binary modules....On May 3, 2001, the Bluetooth protocol stack called BlueZ which was written by Qualcomm was released under GPL. This new stack followed the socket based approach. One month later it was picked up by Linus Torvalds and integrated into the Linux 2.4.6-pre2 kernel. Another Bluetooth stack for Linux was released by Nokia Research Center in Helsinki and it is called Affix. The open source community already decided to support BlueZ as official Bluetooth protocol stack Linux and it became one of the best implementations of the Bluetooth specification.
BlueZ for Android (BfA) provides a "drop-in replacement" for BlueDroid, which means that apps do not need to change...The laundry list of BlueDroid deficiencies also dropped to near zero by swapping BlueZ in...In addition, BfA has been developed as part of the open-source BlueZ project...It is also notable that BlueZ is on its way toward switching to the LGPL. Roughly 80% of the code is already licensed that way, with more coming, though it was not clear when that job would be finished.While it was never said in the presentation, the clear implication of Holtmann's talk was that Google made a poor choice in switching to BlueDroid.
bluetooth support doesn't work and isn't going anywhere.
Of these, you may possibly miss bluetooth support. Unfortunately, the current code doesn't work and isn't structured properly to encourage much future development.
