Hi guys

Very compliments for your CM10.1 last release. It's very nice and works good !

 

To Fix Bluetooth :

1) you have to compile the kernel with uhid driver and without all bluetooth section drivers and without rfkill drivers.

2) use the files from  Christiantroy Patch http://www.mediafire.com/download/0hvj6cqeu3c7stb/jb-mr2-usb_bluetooth.zip. dont' flash the zip , simply use the libs and remember at boot to run "bt-helper"

 

have Fun !

Thanks for feedback yatto!

 

I can load an uhid module (attached) and use the libs from your post.

However, I cannot manage bluetooth working (0a12:0001 Cambridge Silicon Radio, Ltd Bluetooth Dongle).

Oma,

  Be sure that no bluetooth and rfkill stuff are  in the kernel to get BT working.

 

I removed them from my kernel : (bluetooth, btusb, bnep, rfkill, etc. etc.)

than i added uhid driver.

 

from the zip

put libbt-hci.so and libusb.so in /system/lib

put libbt-vendor.so in 7system/vendor/lib

put bt-helper in /system/bin and give it 755 permission

put bt-reset in /system/xbin and give it 755 permission

put in init.d the script that start bt-helper. If bt-helper does not start BT will not work !

 

On my tab and others from my friends, with your rom cm10.1 rel 1.2.3 for rk29board it works !

Bye,

 

  yatto

Thanks for your reply.

Do you have sources for the libbt-vendor and libbt-hci.so?

Hi Netlars, i don't know where you can find the source but here you can find some stuff:

1) the Christiantroy post tht explains how the hack works:

http://www.slatedroid.com/topic/42380-rom-aokp-42-for-elf-ii-aurora-ii-crystal-fire-2013-07-27-update/page__view__findpost__p__953785

2) the Google Plus page of the author:
https://plus.google.com/+RicardoCerqueira/posts/4b3X4di33Lm

3) the source ?!?!
https://github.com/CyanogenMod/android_external_bluetooth_bluedroid/tree/cm-10.1
4) the source from Christiantroy git ??
https://github.com/christiantroy/android_actions_gs702a/blob/jb-mr1/android_external_bluetooth_bluedroid/0001-gs702a-initial-merge-of-Actions-code-by-ChristianTro.patch

I hope you can find it.

have Fun !

 

P.S. : BT works on cm10.1 rel 1.2.4  and not rel 1.2.3 (i did not try it) that i wrote yesterday...

 

Yatto :)

Ok, fresh new kernel and BT works ;-)

We need to find a more generic solution, which will work on any stock kernel.

O more generic solution ?!?

This is a generic solutions, becouse most of the stock kernels no have BT and RFKILL drivers.

So you can apply this patch and load the uhik.ki moduke at boot.

 

A little question for you Oma, I see in your screenshot that you tab has 333MB of system memory avaiable.

How much memory have your tab ? 1GB ? 512M.  What's the source of thath kernel ?

 

A little question for netlars : Why the rom has no hwcomposer ?!?

 

Bye,

 

  Yatto!

Odys Loox has 512 MB. Sources are on our git.

 

Hm, there are a lot of stock kernel coming with rfkill.

With my stock kernel this solution won't work. Loox does not have a combi-chip.

Can you pls test with mediacom stock kernel? Uhid.ko is in post #2. Thank you.

Why you add the btusb.ko module in the fix ?!?!

It'is not needed or not ?!?! :S

 

Now you can remove the issue from the website ;)

 

P.S.  Hwcomposer ?!?! When a fix for it ?!?! :)

The btusb.ko is not in the fix. From what I understood the module is not necessary.

However, I cannot test it here. So feedback is necessary.

You're right btusb is not in the fix, i see :

 

insmod /system/lib/modules/btusb.ko
chmod 666 /dev/btusb.ko

 

in bluetooth script in init.d

I the early days we have huge problems with hwcomposer, as it gives us certain soft-reboots.

In current build hwcomposer will not have advantages anyway.

Pls find it attached. You can use it if you like.
