i think i have fixed the ugly bluetooth battery drain bug.
It works for me since yesterday evening. Battery drain is between 2ma and 5ma with GSM and BT enabled. Also the headset in my car works very well.
Base for my work was tytungs kernel git - i think it was v8, but not sure...
In this post you will find a patch file, the compiled kernel and the source files i have modified. I'm a absolutly beginner with compiling linux, so i am not sure that the patch file will work, diff has a realy big manual
Also i am not sure how this kernel will work with Sense roms, because Sense use btld which has the power saving features in the binary and not in the kernel.
Last but not least i will thank Charansingh for the work he has done on the BT problem and tytung for his kernel base.
If you like to test the kernel, please take also my modules, because i get with the precompiled files from tytung a version magic error.
Your feedback is highly appreciated.
In this Post you will find the zip file for updating magldr
Here you find the zip file for updating clk
Just found another point to save 3 to 5ma more
I installed Typhoons CM7 Image and was wondering why me drain in standby was 7 to 10ma with BT enabled.
Yesterday with Charansingh's nightly it was arround 3 to 5ma.
The solution is to set the low power flag on brcm_patchram_plus in init.rc
service hciattach /system/bin/brcm_patchram_plus --enable_lpm --enable_hci \
--baudrate 3000000 --patchram /etc/firmware/bcm4329.hcd /dev/ttyHS0
Also seen that in a lot of images hciattach service is set in init.rc and init.htcleo.rc
In my experience the hciattach service should start only in init.rc, before bluetoothd service.
