Validate wl1271 Bluetooth support in panda board?

Other Parts Discussed in Thread: WL1271

Hello,

I'm trying to run bluetooth with panda board, since bluetooth is really new to me, and I have some questions as follows

(some are entry-level Q).

1. Which kernel can support panda bluetooth well? upstream kernel, linaro kernel or some else?

2. How to test bluetooth? after search and I got below steps.

    1. dbus-daemon --system

    2. start bluetoothd

    3. hciattach -t 60 ttyS0 texas 115200 noflow

    4. hciconfig hci0 up

    5. hcitool scan

    6. hcitool cc xx:xx:xx:xx:xx:xx

If everything are ok after those steps, which means I can use wl1271 bluetooth to talk with other bluetooth devices?

3. Is there someplace has the prebuilt filesystem which included these files(bluetooth library and hciattach etc).

Thanks for your help in advance!

Regards,

Gary
