Re: hciconfig on android with bluetooth support

[Pavan Savoy]

Did you do that after you turned on the BT ?

May be you need to run hciattach & bluetoothd to turn BT on.

May be the device is not even running BlueZ. The best thing to do is to check init.<product>.rc for any BT related services.

Hello, 

I have a mini galaxy with android 2.3 which has a bluetoth support. I can scan from outside and 

pair while the bluethooth is on. Now, I have root access on this device.

I had followed the instructions here:

http://forum.xda-developers.com/showpost.php?p=9993128&postcount=37

And while the bluetooth is on, I tried to run hciconfig -a, both from the terminal and 

from adb shell. In both cases I get nothing.

Any idea why ? in the example in that link we see that "hciconfig" finds the Bluetooth UART device.

Rgs,

Hi,

BT is turned on.

I can see from a remote laptop with bt support, and I can see the android phone.

I have root access in the android device, and ps shows that bluettoth is running.

Strange!

Can somebody who has root access and has BT supported device check with If he has 

entries under:

/sys/class/bluetooth/

(I do not have)

rgs,

Kevin

Hello,

Well, after googling and making some tries, I came across this post:

http://blog.csdn.net/sunrock/article/details/6573237

ls -al  /dev/ttyS1

gives me : No such file or directory

So I tried:

cat /init.rc | grep bluetooth | grep dev/tty

and got:

    chown bluetooth bluetooth /dev/ttyHS0

So I tried:

hciattach /dev/ttyHS0 any 3840 0 flow

It said: 

Device setup complete

hconfig  returned:

hci0: Type: UART

BD Address: 00:00:00:00:00:00 ACL MTU: 0:0 SCO MTU: 0:0

DOWN 

RX bytes:0 acl:0 sco:0 events:0 errors:0

TX bytes:0 acl:0 sco:0 commands:0 errors:0

And now there was an entry under /sys/class/bluetooth.

I wonder why the address is all zeroes (even that it is down). Should it be so ? 

then 

hciconfig hci0 up

And the phone get stuck. Recovery mode did not work. I had to take the battery out and insert it.

Any ideas? 

What is the /dev/ttyHS0 for ? is it some generic Linux UART serial port? 

Or some generic Android UART serial port?
