Bluetooth does not work on Origen

[Zach Pfeffer]

On https://android-build.linaro.org/builds/~linaro-android/staging-origen-11.09-release/#build=2
Bluetooth doesn't work. When you enable it on the UI it just sends back an error.

Affects 11.09, 11.10 releases.

[Angus Ainslie (angus-akkea)]

Bluetooth enablement is not complete for the Origen board. The LT is
currently working on it.

Samsung LT made How Doc:
 - https://wiki.linaro.org/Resources/HowTo/SamsungBTInOrigen

We need to prepare two patches for Bluetooth in Origen
1) Platform specific
   released internally and loading into g.l.o

2) rfkill gpio specific
One patch is released to Wireless mainline mailing list:
- https://lkml.org/lkml/2011/9/26/240
and preparing one more patch now to be released

[Sangwook Lee (sangwook)]

Bluetooth Driver is complete, Now it is time to update Android Platform source code.

Android Platform Source code:
please add the following:
-----------------------------------------------------------------------------------------------------------------------------------
Init.origen.rc:
service bccmd /system/bin/bccmd -t bcsp -d /dev/ttySAC0 psload -r /system/etc/bluetooth/origen.psr
    disable
    oneshot

service hciattach /system/bin/hciattach -s 921600 /dev/ttySAC0 bcsp 921600 flow
    disable
    oneshot

-------------------------------------------------------------------------------------------------------------------------

"bccmd" is located at /external/bluetooth/bluez/tools/bccmd.c of the current Androd platform source code.

[Sangwook Lee (sangwook)]

To compile bccmd.c file, it is needed to set "BOARD_HAVE_BLUETOOTH_CSR".

For details:
http://nv-tegra.nvidia.com/gitweb/?p=android/platform/external/bluetooth/bluez.git;a=log;h=refs/heads/rel-12r3

Apply patch (my idea) for Android Bluetooth in Origen

File: system/bluetooth/bluedroid/bluetooth.c of Android platform

    if (set_bluetooth_power(1) < 0) goto out;

+ LOGI("Starting bccmd daemon");
+ if (property_set("ctl.start", "bccmd") < 0) {
+ LOGE("Failed to start bccmd");
+ goto out;
+ }

    LOGI("Starting hciattach daemon");
    if (property_set("ctl.start", "hciattach") < 0) {
        LOGE("Failed to start hciattach");
        goto out;
    }

Note that the end stage of executing "bccmd" will return error,
but we have to ignore that.

Further Information:

Function init_rfill() in the above file will check out the following two files, which is currently supported by Linaro Kernel.

Scanning function/Discovery was verified in Ubuntu.

Bluetooth rfkill-gpio driver is implemented in Linaro Kernel.

Android BT functionality will be verified later.

There is a dependency on an origen.psr file that has unknown licensing.

[Ricardo Salveti (rsalveti)]

Also happens with 11.11 RC on Ubuntu side.

Valid for https://android-build.linaro.org/builds/~linaro-android/staging-origen-11.11-release/#build=3 as well.

[Botao (botao-sun)]

After applied these 3 changes: 1024, 1031 & 1032, the "bluez" module has been added into manifest with 4.0.1 branch; the "bccmd" has been compiled successfully and transferred to the path "/system/bin".

However, there is no "Bluetooth" item in "Settings" menu, so I can't test it from UI in this condition.

Either the initilization cammands in init.origen.rc haven't been run
or something else needs to be done in userland to have the device
recognized.

The return value of "hciconfig" is empty:

root@android:/system/modules # hciconfig
root@android:/system/modules #

Looks like the Bluetooth chip can't be recognized. After I run "hciconfig up", it shows:

Can't get device info: No such device.

Below is the code in "init.origen.rc" file which is related to the Bluetooth:

# For Samsung Origen Bluetooth Feature
service bccmd /system/bin/bccmd -t bcsp -d /dev/ttySAC0 psload -r /system/etc/bluetooth/origen.psr
    disabled
    oneshot

service hciattach /system/bin/hciattach -s 921600 /dev/ttySAC0 bcsp 921600 flow

Does 'disabled' mean these commands aren't to be run ?

If these commands don't run the bluetooth chip won't get initialized

[Botao (botao-sun)]

1. About "disabled" keyword:

This keyword means this service will not be executed during the boot process, it will be performed by the component at the time when need it. For example, WPA Supplicant service will be run after user clicks Wi-Fi from "Settings" menu to enable it.

Therefore, the bccmd and hciattach won't be run until someone clicked Bluetooth to enable it. But there is no Bluetooth item in "Settings" menu.

2. There is no "origen.psr" file:

The "origen.psr" doesn't exist in ICS, so this command won't be executed successfully - /system/bin/bccmd -t bcsp -d /dev/ttySAC0 psload -r /system/etc/bluetooth/origen.psr (I tried, the result is: Initialization timed out).

Should I create it by myself? If so, what contents should I add in?

3. I read this article https://wiki.linaro.org/Resources/HowTo/SamsungBTInOrigen, and according to the description, the Android platform requires "rfkill" to turn on / off the Bluetooth, but there is no "rfkill" in ICS.

[Botao (botao-sun)]

The changes based on "origen-device.diff" and "origen-psr.patch" which Angus sent to me have been submitted and merged. However, I still got the error when I run the command manually:

1|root@android:/ # /system/bin/bccmd -t bcsp -d /dev/ttySAC0 psload -r /system/etc/firmware/bluetooth/origen.psr
Initialization timed out

1|root@android:/ # /system/bin/hciattach -s 921600 /dev/ttySAC0 bcsp 921600 flow
BCSP initialization timed out

1|root@android:/ # ls -l /dev/ttySAC0
crw------- root root 204, 64 2000-01-01 00:41 ttySAC0

There is no error, but only timed out. Need to investigate it.

[Sangwook Lee (sangwook)]

Before you running,
$ /system/bin/bccmd -t bcsp -d /dev/ttySAC0 psload -r

Please make sure that

1) Kernel log
You have to see from kernel booting message:
  1.405000] rfkill_gpio rfkill_gpio: origen-bt device registered.
which means that kernel already has rfkill gpio module.

2) Can "printf of bccmd cmd source" appear in Android command line ?

it shows as like

3) Permission setting of ttySAC0:

crw-rw---- 1 root dialout 204, 64 1970-01-01 00:00 /dev/ttySAC0

[Sangwook Lee (sangwook)]

Please make sure that you have the following kernel booting message:
You have HCI BCSP protocol in kernel booting message. HCI BCSP is used by command "bccmd".

4)
     1.360000] Bluetooth: HCI UART driver ver 2.2
[ 1.365000] Bluetooth: HCI H4 protocol initialized
[ 1.370000] Bluetooth: HCI BCSP protocol initialized

[Sangwook Lee (sangwook)]

Sequence in summary:

1) Initialize Bluetooth device
$> bccmd -t bcsp -d /dev/ttySAC0 psload -r origen.psr

2) Connect Serial driver to CSR Bluetooth external chip as the speed of 921600
$> hciattach -s 921600 /dev/ttySAC0 bcsp 921600
Device setup comp[ 3100.020000]
Bluetooth: Out-of-order packet arrived, got 1 expected 0 <== Ignore this, it's fine

3) Up the Bluetooth stack
$> hciconfig hci0 up

4) Show current Bluetooth device
$> hciconfig -a

Did you run scanning command ? or Is it from initialisation ?
At first glance, it seems not to from booting up from Bluetooth.

If possible, please upload kernel message as well.
