I also changed:
case RTBTH_IOCDMAC:
do {
struct rtbth_dmac dmac;
if (copy_from_user(, (void *)arg, sizeof(dmac))) {
retval = -EFAULT;
DebugPrint(ERROR, DBG_INIT,"copy_from_user failed at %d\n",
There is a fix for the pairing on https://github.com/loimu/rtbth-
dkms/pull/4
for the RTBTH_IOCDMAC: dmac.dmac_op=2
Blaze, can you take look at this pull request and let it test?

I traced the rtbt binary on 12.10. The result is:
Ubuntu 12.10:
48609b - jump taken
4860b3 -jump
4860cc - no jump
486102 - jump
48615c - jump
It means, that the _v16 value is zero on Ubuntu 12.10. So the function
LM_Find_Link_Table_Entry() should return 0 value. For some reason the
At the address 0x48615c I've got jump, so the memory at the address
(_v16 + 220) & 255) equals 0, which is wrong. This way we never reach
the _LMssp_Send_LMP_DH_Key_Check() routine.
I would need to trace this on Ubuntu 12.10 where is the pairing

I would first get the source diff of bluez and when we have the root
cause of the pin mismatch, then I would decide whether is reasonable to
patch bluez or the rtbt binary.

The default pin does not matter. In ssm both pins are shown up. Each
time a new set of pins is generated. When I click on accept pin, the
rtbt routine LMssp_LM_User_Confirmation_Request_Reply is being executed.
When I traced the binary, for some reason the comparison routine is not
reached. It can
Is it possible that the changes to bluetooth package affect the driver
pairing? What I have tested, the Bt v4 pairing on Ubuntu 12.04 and 12.10
succeeds, but on 14.04 and later not. The differences that could affect
the functioning are kernel and bluetooth package - bluez. When I tried
to pair
The work was done previously, before you took over the source. Check the

When you want to patch the rtbt binary with newest firmware, you should
do it befofe sudo make install. You can repeat the sudo make install
after patching the binary. I will give it a try on 12.10 live system.

I am wondering what the Mediatek is going to protect with NDA. The

Strange, because I used the script in tools to update the firmware in
the binary rtbth driver loader, then reloaded the driver with modprobe.
Is the driver confirmed to work on other systems? Does it pair BT V4
devices as well? I can pair and transfer files with BT V2, but not

I was able to test the driver from https://github.com/f1u77y/rtbth on my
RT3290LE Bluetooth adapter. The pairing with A2DP device - Nokia 5230
was successful, but pairing with an android device with BT ver 4 not.
The hcitool reports lower version of BT - 2.1 than the device itself is
capable.
