Which Kernel should I use?

Hello,

I´ve solved a problem with Bluetooth Driver although I would like to understand why. I have installed: BBB-eMMC-flasher-ubuntu-14.04.1-console-armhf-2014-10-29-2gb.img

Problem was that this device although recognized were not usable (“hcitool dev” not showing any device)

Bus 001 Device 003: ID 0a12:0001 Cambridge Silicon Radio, Ltd Bluetooth Dongle (HCI mode)

I´ve tried these Kernels:

3.14.26-ti-r39 → NOK
v3.18.0-rc7-bone1 → NOK

v3.8.13-bone68 → OK

With the latest one Bluetooth device is working properly (although I have not connected successfully yet to a Headset). My question is, why? Which are the differences between them?
Any ideas why I cannot pair with my bluetooth headset?

In other hand, I´ve tested also Debian BBB-eMMC-flasher-debian-7.7-console-armhf-2014-11-19-2gb.img but WiFi took over 5 minutes to be ready… I do not why… I didn´t try to update kernel but I will, this is my Dongle:

Bus 001 Device 004: ID 0bda:8176 Realtek Semiconductor Corp. RTL8188CUS 802.11n WLAN Adapter

Thanks for your support, great community!

OH... it would probally would have helped if i actually enabled
CONFIG_BT_* options in the kernel config..

DOh..

the 8188's are picky.. Do you have a usb extension cable to get it
away from the hdmi ground plane?

Regards,

Yes probably it would helped! XDDD glad to collaborate. :slight_smile:
Regarding WiFi, I have connected through an USB HUB, the thing is that it has no problem with Arch or Ubuntu, only with Debian. I will try to change Kernel if it helps. If you need some additional info just tell me.

Thanks for your support Robert, your are great!
