Kitkat Kernels for All (well most!)

Bluetooth Low Energy

Hi d33,
I use a TV-Stick MK809iv KitKat with RK3188 and AP6210.
I need WIFI and Bluetooth Low Energy. Can you make a kernel with this feature? Can the AP6210 ever work with Bluetooth Low Energy?
Regards Billy

Hello d33:
Thanks for your kernels,RTL 8723bs works fine but I find my rk device does not have hdmi sound.
I tried to build my kernel with https://github.com/linux-rockchip/kernel_rockchip/tree/rockchip-3.0-rbox-kk ,but the same problem occured(no sound).
Finally,I followed these steps then hdmi sound was ok.Would you like to provide me a special kernel for the sound probelm?

Edit : For the record, here is dmesg of thestock rom : http://pastebin.com/F6kaCFNv

I've uploaded a new RTL8723AU tester in the first post which should do BT too.

I don't flash from Ubuntu so can't help on the flash problem, sorry.

No idea on Low Energy? What should I be looking for? Are you refering to BT 4.0?

Try the kernel I uploaded on the first post (I accidentally omitted RK1000 HDMI sound support on the one I posted above)

The stick supports BT4.0 and according to data from AP6210 even BT protocol for Low Energy is supported. Also works partially, pairing o.k. , Data transmission start and then abort. Think it is a software problem.

I've checked the RK wifi patch site and there are only two patches released for BT 4.0; one for MT6620 and the other for RTL8723BS. Both are patches for Android OS and not kernel.

There is an APxxxx fix for BT PCM - I can try to apply but the text is chinese and so I'd be guessing

Ahh this is OS too!

slash kernel

ive got a mk908II tried a couple of your kernels with finless kk beta 2 out of those ive tried no boot but im not sure im doing right im fairly confident. i would have thought the right kernel would be r3188t ap6210 tried non t as well but no joy. Does it need renaming before flash is there something im missing eg clear dalvick? Im pretty sure i dont need j22. Any help would be great

cam someone please tell me how to flash the new oc kernel?

is it with rk android tool with just kernel marked for flashing??

tried it but it boot loops or stuck on logo

please help!!!!!!!!

That is the correct way to flash.

What I meant was it is possibly best to post in a sub-forum where people have the same make/model as you and see what ROM combinations work for them.

The chances are your SoC has an unstable PLL and so wont boot without the T 'locks' in operation

d33, is there a way to turn off these messages on logcat?

D/[BT]    ( 2765): bt_eint_monitor: EINT arrives! Notify host awake
W/[BT]    ( 2765): bt_host_awake: bt_host_awake
D/[BT]    ( 2765): bt_host_awake: Send host awake command success
W/[BT]    ( 2765): bt_host_awake_evt: bt_host_awake_evt
D/[BT]    ( 2765): bt_host_awake_evt: Receive host awake complete event

They are making my logcat HUGE when I turn on bluetooth.

Any ideas d33? How to turn these off?

I can look into it.

[edit] Messages come from ROM - I've looked at source and they can be removed but you would need to ask the ROM builder to remove

cyx_cs918_v_2_1 + wasser-firmware-kr42-new-1.0.4 + kernel_KK_v4.2.4_TVBOX_RTL8723au_HD

Hi d33,
Finally, by using windows, then linux, and briking my device twice, I succeed in flashing your v4.2.4_TVBOX_RTL8723au kernel over wasser-firmware-kr42-new-1.0.4.img

I tried several overclocks configurations and get some freeze or bootloops for cpu>1608h
I'm actually testing this configuration : cpu1608h_gpu798h_ddr800.

Actually, I can't get no wifi, no blutooth, and no ethernet so it's quite limitated... I don't know if i's due to wasser firmware which of course is not adapted to my device (cyx_cs918_v_2_1), and/or your kernel.

Here is my dmesg : http://pastebin.com/WS9H81pG

Does JB and KK kernels are compatibles, so I could try various combinations of firmwares / kernels ?

I'm gonna keep playing with that, so just tell me if I can do something to help improving your kernels.

Cheers

looks okay?

Can you provide a DMESG from stock ROM/kernel?

Just to be sure I've rebuilt the RTL8723au kernel here
