I'm definitely interested!

my wife come back and some thing fu... up.
i needto find what:"

I would be interested in how you got it working. 2dark4u kernel?

I tried many times to get it working with dongles but was not successful.

Thanks! Looking forward to it. Is it a kernel fix or is it a Rom level fix?

i was to optimistic sayin "all rk3066 devices"
BOB for now to get it to work you will need mk808b kernel flashed on mk808 to do the trick.
btusb.ko of course is needed to.
as of now i can get it to work from the ui but not all the time.
i need to find the trick for rfkill to always pick up bluetooth dongle insted of virtual one that is created under
/sys/class/rfkill/rfkill0/

Same problem I have seen with CM10. It will work sometimes and not others! I ported and made the modifications that CM10 used for BT dongle support and got the same results on MK808 ROM.
A while ago 2dark4u even tried compiling in the BT drivers into the kernel and we were still unable to get it working reliably.

My AMLogic devices all work 100% with BT dongles and I even spent some time tearing through that code to see why. No luck

you need kernel with pached rfkill bt section.
cm uses difrent aproach.

I have a ROM with btusb.ko installed.

Also in CM10 I noticed this change to init.rk30board.rc

#service hciattach /system/bin/brcm_patchram_plus --patchram bychip --baudrate 1500000 --enable_lpm --enable_hci /dev/ttyS0
service hciattach /system/bin/busybox true

They commented out the standard line and added the busybox call.
I did this and this is when I got it working sometimes on MK808.

Just FYI. So I think hciattach is for sure involved! For instance when I ported one of my ROMs to the MK808B, I had to take hciattach from the original ROM or BT would not work.

Oh and also see this stuff in that file as well

on init

chown bluetooth bluetooth /sys/class/rfkill/rfkill0/type
chown bluetooth bluetooth /sys/class/rfkill/rfkill0/state
chmod 0664 /sys/class/rfkill/rfkill0/state

Try a permissions change here. I think owner should not be bluetooth for a dongle!
This is where I left off with 2dark4u and he kept telling me he thought there was a permissions issue.

yap. thats what i was talking about.
they use this file brcm_patchram_plus to make it work.
thhanks for info.
i will post back when i will find something.

[lewy20041]

hciattach is used for uart/serial bluetooth which is presented in mk808b.
we use usb insted so hciattach may not be neded:"
