[Android Q&A, Help & Troubleshooting] rybak02:
I have problem with changing bluetooth mac adress in my phone:

CPU	Qualcomm MSM8225Q 4 x 1,2 GHz; GPU	Adreno 203; Android 4.1.2 Jelly Bean

After paring phone with pc and switch of bluetooth, next time i must paring one more time.

I find reason this problems, mac adress in phone is changing .

Can someone help me edit file to set static MAC adress and device name?

Can I change adress in this file?

If not, where I can do this?

I think

- add in file:

BTS_ADDRESS="00:a0:c6:90:03:b6"

- change in function

start_hciattach ()
{
/system/bin/hciattach -n $BTS_DEVICE $BTS_TYPE $BTS_BAUD &
hciattach_pid=$!
logi "start_hciattach: pid = $hciattach_pid"
echo 1 > $BLUETOOTH_SLEEP_PATH
}
