Hi,
I am porting bluez 5.33 to android kitkat 4.4.3.I am using USB based
Bluetooth device. I referred instruction in
http://git.kernel.org/cgit/bluetooth/bluez.git/tree/android/README and
able to build.
After botting Android image with USB dongle connected and type "hciconfig
hci0 up" on console, It is throwing following error.
Can't init device hci0: Unknown error 132 (132)
If I Type hciconfig -a . It gives following.
hci0: Type: BR/EDR Bus: USB
BD Address: 5C:F3:70:6C:5E:FB ACL MTU: 1021:8 SCO MTU: 64:1
DOWN
RX bytes:547 acl:0 sco:0 events:27 errors:0
TX bytes:384 acl:0 sco:0 commands:27 errors:0
Features: 0xbf 0xfe 0xcf 0xfe 0xdb 0xff 0x7b 0x87
Packet type: DM1 DM3 DM5 DH1 DH3 DH5 HV1 HV2 HV3
Link policy: RSWITCH SNIFF
Link mode: SLAVE ACCEPT
But If I unplug and plug USB dongle, and then try same command (hciconfig
hci0 up), It works. Even "hcitool scan" command also working after that.
Why 1st time not working when USB dongle is connected?
Also when I check Bluez debug log in logcat.
I am getting one error log when USB dongle connected during boot.
E/bluetoothd( 841): Failed to set mode: Blocked through rfkill (0x12).
Please let me know If I missed any settings
Thanks in advance,

Hi,
Thanks for the reply.
In my busybox utils rfkill is not enabled. If I enable it and try "rfkill
unblock" is that will be enough? or I need to search for Kernel patch that
fixes this rfkill block issue?

I think that blocked through rfkill is pretty obvious. Check with the rfkill tool on what the current settings are. For some reason it seems Bluetooth is blocked by default. And I remember there were some kernel patches for this. Just do not remember the details.

Please enable debug logs for daemon (check android/README for how-to) and
provide both debug logs and btmon HCI traces.

Hi,
I am using Bluez 5.33 on Android kitkat 4.4.3.
I am testing GATT functionality and I found that sometime
onWriteCharacteristic returns status 1 (BT_STATUS_FAIL). In android
Application I am checking for success status (i.e. 0) which I am getting
most of the time. But occasionally I am getting Status 1 because of which
my application logic is failing.
When Bluez will send Status 1 and on what basis? How to avoid this?

for a lot of Bluetooth controllers we have support for Set Public Address management command. If the kernel driver provides the vendor specific hdev->set_bdaddr callback, then in theory you can have BlueZ for Android programming the address into the controller even if you swap it out.
If you do that, then you would not see this message. However that is just how Android handles things and we have to deal with it. Feel free to send patches to start supporting Set Public Address handling.

I have added call to init and get_profile_interface function in Android
JNI in enable Function so that we can initialize the BT HAL.
With this change BT is turning on even if I connect the dongle after Boot.
Thanks for the support.
I observed one more issue when I connect different USB dongle. Was getting
"Bluetooth address mismatch" error as in cache previous connected USB BT
hardware address is saved.
Is that check required? After bypassing that check, BT is working with
different USB dongle also.

Hi Szymon,
Thanks for your reply.
I just checked BT enable flow from android and found that
When USB BT Dongle is not connected during bootm,During Bluez Init
(hal-bluetooth.c:init()), hal_ipc_accept is failing.
I hope IPC is failing as USB BT dongle is not connected.
>From below Logcat suggests that
E/BlueZ ( 799): bluetoothd connect timeout
E/BluetoothServiceJni( 799): Error while setting the callbacks
E/BluetoothAdapterState( 799): Error while turning Bluetooth On
because of this none of the BT interfaces are initialized.
When we connect the USB BT dongle , hal-bluetooth.c:init() is not getting
called. because of this BT enable is failing.
But in working case (USB BT dongle connected during boot). Each time when
we connect BT dongle, init is getting called.
I also observed that If I remove the USB dongle without turning off BT
from android BT settings menu, at that time
also init is not getting called and because of that BT will not get
enabled properly.
If we make "init" function to call whenever BT dongle it connected, is
that will be enough for BT HAL module to work
properly or any other settings might be required?
Regards,
KP

I don't think Android supports BT adapter hot-plug. What I mean by that is
during Framework tries to initialize BT subsystem (and clean it up right after
that). If that fails (eg due to no adapter being present) it will not try to
initialize BT HAL again. So enabling BT from UI fails before even calling BT
HAL.
If adapter is present on boot, and then you remove it and plug it again it
should work. Yet, if adapter is changed (so that address changes) you are
entering uncharted territories, so you may see some subtle hiccups.

Hi Szymon,
Bluez module is loading on boot. Some initial Bluez debug prints are
coming. like following logs which are coming initially
-------------------------Log start---------

But after that bluez function calls like
open_bluetooth,get_bluetooth_interface,init are getting called after
boot_completed signal received android, Its calling BluetoothMapService
and from there call is going to bluez over JNI.
Below Log suggests that.

Android System server during init will get BT name and address and after
that I did not find any other place where it checks for name/address.
Correct me If I am wrong. or I am missing anything?
hciconfig/hcitool is working fine if we connect BT dongle after boot.Only
problem when we try to turn on BT from Android Bluetooth settings menu.

KP

This should work but you need to load modules on boot (or have all compiled
into kernel).

Hi All,
I analysed the Android flow and found that Android System server will
initialize and check for bluetooth hardware on during Boot. So if we
connect the USB BT Dongle after boot Android BT service may not identify
it.
May be this is the reason because of which scenario 3 (Boot Android device
and then plug the USB BT Dongle.Then Turn on from Bluetooth setting) is
not working.
This is my understanding. Correct me If I am wrong.
Anyone tried USB BT pnp on android?

KP

Hi,
By Analysing I found 3 scenarios and only in one scenario BT is working.
Scenario 1 : Connect USB BT Dongle and then boot the android device.Then
Turn on from Android Bluetooth settings
Result: Not working. Rfkill block error.
E/bluetoothd( 868): Failed to set mode: Blocked through rfkill (0x12)
Scenario 2: Connect USB BT Dongle and boot. Then unplug and plug again.
Then Turn on from Android Bluetooth settings.
Result: Working: BT turning on and scanning BT/BLE devices.
Scenario 3: Boot Android device and then plug the USB BT Dongle.Then Turn
on from Android Bluetooth settings.
Result: Not working. Here we are not getting any debug prints from bluez.
Whether we need to rerun the init.bluetooth.rc as BT Dongle was not
connected during boot.

For Scenario 1 , I am trying to build rfkill tool for android(Currently no
success). Can we change the state from code by opening rfkill path
"/sys/class/rfkill/rfkill0/state" and write 1 to enable?
But scenario 3 looks like I missed some configuration.
What could be the problem?

Hi,
Thanks for your suggestion. That was the problem.
CONFIG_CRYPTO_USER_API_HASH was not enabled to Kernel. Now BLE scanning is
working.
Thanks a lot.

Yes, profile must be initialized if you want to use it.

There is no daemon logs here but my guess would be that required crypto stuff
is missing in kernel. Check "Linux Kernel requirements" section in
android/README for list of required kernel options.

Hi All,
>From the Android Logcat I found that GATT JNI is failing to initialize
E/BtGatt.JNI( 833): ERROR: void android::initializeNative(JNIEnv*,
jobject)(L718): Failed to initialize Bluetooth GATT, status: 1##
Is this could be the reason for startlescan to return false?
Regards,
KP

Hi,
I have ported bluez to Android Kitkat 4.4.3 and I am testing Bluetooth Low
energy from android application.
BluetoothAdapter's method startLeScan returns false during scanning BLE
devices.
register-client method is getting called in hal-gatt.c. But looks like
"scanStarted" function is returning false.
Have anyone faced this issue.
Thanks in advance
KP
