"How to enable BT on board imx6q_sabresd" my bluetooth service isn't started.

gongliu — Wed, 24 Dec 2014 12:03:57 GMT

i want to enable bt on board imx6q_sabresd with android 4.3 , ,and i follow this How to enable BT on board imx6q_sabresd RevC.to Configure my bsp code,but id didn't work ,the type of my bluetooth chip is "ivt_BlueSoleil_i480e".

now i can power on the rfkill,and set "sys/class/rftkill/rfkill0/state" to 1.but the can not enable BT, the logcat says "E/BluetoothAdapterState( 3195): Error enabling Bluetooth"

and in "/device/fsl/sabresd_6dq/BoardConfig.mk" i set "BOARD_USE_AR3K_BLUETOOTH := true",so in "/hardware/imx/libbt-ath3k" module.

the logcat is:

I/bt_upio ( 3195): open set_bluetooth_power success

I/bt_upio ( 3195): write bluetooth_power success

Hi gong

this appears to be a timeout issue, and is probably a setting that Sliex provides for their driver.

Have you consulted with Silex?

Best regards

Hi Liu gong,

I think it is the issue on preload with bluedroid.

You may try this patch on your external/bluetooth/bluedroid . I think this patch will work.

Hi,

I may make the mistake. "ivt_BlueSoleil_i480e" is it the Atheros solution? Our Android BSP support atheros 3002 series BT only.

Re: "How to enable BT on board imx6q_sabresd" my bluetooth service isn't started.

gongliu — Sun, 04 Jan 2015 05:21:15 GMT

Hi,

i think my BT type "ivt_BlueSoleil_i480e" is not the Atheros solution, so how can i change the Android BSP code? in addtion, it use the BlueSoleil Stack.

gongliu — Sun, 04 Jan 2015 10:55:28 GMT

hi, at addtion , i want to known , in your bsp code"~/device/fsl/imx6/etc/ini.rc" the service "service dbus /system/bin/dbus-daemon --system --nofork" and "service bluetoothd /system/bin/bluetoothd -n" is need?

haoranwang — Sun, 04 Jan 2015 12:39:49 GMT

Hi Liu,

I think you have to get the SDK for your BT module from the vendor. As the libbt-vendor must be implement by the BT vendor.

for the init.rc service, yes, they should be keep.

Hi wang,

Hi, wang

i have another question, when the sabresd board Start up succeed, the logcat show this:

.......

init: sys_prop: permission denied uid:1003 name:service.bootanim.exit

ehci_fsl_bus_suspend begins, Host 1

ehci_fsl_bus_suspend ends, Host 1

rfkill: BT RF going to : off

rfkill: BT RF going to : on

mx6q_sd_bt_reset

rfkill: BT RF going to : off

rfkill: BT RF going to : on

mx6q_sd_bt_reset

rfkill: BT RF going to : off

rfkill: BT RF going to : on

mx6q_sd_bt_reset

......

The "rfkill: BT RF going to : off" and "rfkill: BT RF going to : on" every show six times.

i did nothing ,just let "uart5_enabled = 1;". why the BT rfkill always reboot?

haoranwang — Mon, 12 Jan 2015 01:34:04 GMT

Hi Liu,

The BT service will try to restart the stack if it is not enabled successfully.

If you once enabled BT in settings panel the BT state will be store into the /data. Then you reboot board the BT service will be "enabling" state and will try to restart the stack if it is failed.

So that log is normal.

Hi Haoran wang,

I am new to bluetooth porting on Android KK 4.4.3, May I know how to start and make my bluetooth up and running.

My platform is imx6sl (freescale sololite), I have my own bluetooth driver, I need to integrate driver to Android BSP when I enable/disable bluetooth button on GUI my driver should be loaded/unloaded, as bluedroid is replaced by bluez, do I need to change HAL level code or just integrate my bluetooth driver to GUI.

Re: "How to enable BT on board imx6q_sabresd" my bluetooth service isn't started.

haoranwang — Fri, 19 Jun 2015 00:40:50 GMT

Hi,

I remember our AE engineer Tony Zheng who once enabled BlueZ on Android Kitkat for USB dongle.

Hi Tony,tonyzheng

Could you please help mutyalaraoneelapala for his USB dongle?

Thanks.

Hi, Neelapala

The Android UI has enable/disable bluetooth function, so , i don't think you need to inplement by yourself. Of course, you can encapsulate it into your apps;
Before you intergrate own bluetooth driver, you should dig into bluetooth HAL layer in android. Actually, Blueroid has done many jobs for bluetooth stack, what you need to do is implement your own interface protocol, this protocol is defined by bluetooth silicon vendor. please refer to Broadcom and Qualcom bluetooth project
In my opinion, you shoud consult bluetooth silicon vendor to how to implement it. Because it has no relation with freescale SOC silicon and Freescale has only provided UART interface to bluetooth module.

Hi Tao Zheng,

Thanks for the valuable information!!!!

1. If I enable bluetooth using GUI, then don't I need tools like hciconfig, hcitool for scanning or inquiring and all ???. will I be able to get scan results if I integrate my driver to GUI???

2. Can you please tell me, How to consult bluetooth silicon vendor??

Re: "How to enable BT on board imx6q_sabresd" my bluetooth service isn't started.

tonyzheng — Tue, 23 Jun 2015 01:32:12 GMT

Bluedroid stack has no hciconfig and hcitool, they are Bluez tools;
Who are you working for? If you are end-producer, you should try to contact your provider.

mutyalaraoneela — Tue, 23 Jun 2015 12:05:13 GMT

Hi Tao Zheng,

I work for one of the Silicon vendors company. We develop Bluetooth products.

Generally, we tested our product using Bluez stack. Now we would like to test using Bluedriod.

I am facing trouble to find tools simliar to hciconfig/hcitool in Bluedriod. Please suggest me how can I evaluate using Bluedriod.

Also, I have other question.

In your previous reply, you mentioned that Freescale has only provided UART interface to bluetooth module. What do you mean by this?

Our bluetooth module supports only SDIO/USB interface. Since Frescale has USB ports, cant I connect my bluetooth module through the USB interface??

Your help is very much appreciated.
