BlueZ and Android - question

BlueZ and Android - question

[Kevin Wilson]

Hello all,
I have a question:

I saw in several places on the web text which says, in some
variations,  that "BlueZ has been removed starting from Android  4.2
and the  Broadcom-supplied Bluetooth stack (bluedroid) has replaced
it. It says also that the bluedroid
stack relies on HAL-loading like most other hardware types.

On the other hand I see in the official page,
http://www.bluez.org/
something which I am not sure how to interpret.


I want to resolve my confusion.
So here is my question:
In Android 4.2 and above - is the BlueZ removed ? is the BlueDroid
used instead ? or are they both used?


Regads,
Kevin

No.

Now there is a project to provide alternative for Bluetooth stack in
Android.

Andrei,
Thanks a lot for the Quick response.
Can you please provide a link for the alternative for Bluetooth stack in
Android or specify its name ?  I did not know about it.

Best Regards,
Kevin

The alternatives seems to be:

1) backport old BlueZ + Bluetooth framework from Android 4.1.2
https://gitorious.org/android-bluez

2) The new project with the latest BlueZ and Android:
http://code.google.com/p/android-bluez/
(this is initial phase)

3) You can also use Bluedroid with BlueZ kernel drivers via CHANNEL_USER
