Bluetooth on ES Pandaboard with Ubuntu 12.04

[Craig Shaffer]

Has anyone actually gotten a bluetooth device connected to the pandaboard?

I feel like I've tried everything if you've gotten it working can you please post exact / simple instructions.

I've got just a basic image loaded from the binary release of 12.04

Thanks,

/Craig

Well the driver already exists in all the mainline kernel that you get.
It might not be enabled (might be...)

You can find more info regarding the driver here,
http://omappedia.org/wiki/TI_Shared_Transport_Description_and_Support
If you are able to build your own kernel for the panda that you have,
then getting BT working should be fairly easy.

A quick look at the ti-omap4 branch of the ubuntu kernel - I do see
the TI_ST driver and the BT_WILINK drivers are built.
The TI_ST driver as built-in and BT_WILINK as module.

So, Is the btwilink module inserted ? #lsmod - should tell us that.
Also, You will have to run a utility called uim-sysfs - But "no
Bluetooth adapters found" probably suggests that the modules isn't
inserted to begin with.

running #hciconfig -a should at least show up 1 adapter hci0 - even if
it says DOWN instead of UP and RUNNING.
You should also find sysfs entries @ /sys/devices/platform - for both
"kim" device & also for the "btwilink" device.

Well may be it was worth-less, but certainly not as worth-less as your
response to this thread to begin with. Just trying to help here ..
that's all.
We would all want BT to work on Panda board - As much as you do.

sudo hciconfig  gives nothing, no errors, no response.

sudo modprobe btwilink installs  OK, but still no devices found in the Bluetooth Manager applet.

Then hciconfig shows

hci0:  Type BR/EDT   Bus: UART

its marked as DOWN and lists
BD Address 00:00:00:00:00:00 ACL MTU: 0:0  SCO MTU: 0:0


Some one else is going to have to pick this up from here as I just don't care enough about it right now to proceed.

If I plug in a known to work with Linux USB Bluetooth dongle, it seems to work fine in superficial testing.

I have similar (if not same) problems using mainline kernel 3.4.6. After modprobe btwilink, i get these kernel messages:

[75760.163299] (stk) :sysfs entries created

after that hciconfig shows:

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

I however do not run that tool uim-sysfs. I tried cross-compiling it, but it seems to have dependencies on android libraries ?? What is the proper way to get that working.

BTW, external USB BT adapter works fine...

[Pavan Savoy]

find attached the static version of the UIM.
The only dependency it has is for the logging - LOGE/LOGV.

So, I modified or rather had #defined all of the UIM_DBG or UIM_VER to
say printf or fprintf(stderr)
Let me know if this works out.

The main problem is that there is NO place holder for UIM at all - It
is not hosted on any GIT specific to a Linux flavor.

Thanks for fast response!

After I started static-uim:
uim: main
uim:polling now...

Then after "hciconfig hci1 up" it starts repeating the following:

uim:reading install
uim:read install 1
uim: st_uart_config
uim:install set to 1
uim: Can't open ��������
uim:polling now...
uim:reading install
uim:read install 0
uim: st_uart_config
uim: Un-Installing N_TI_WL Line displine
uim: Un-Installed N_TI_WL Line displine

kernel messages the same as are when driver is inserted without uim, previous post.

Should I run something else than hciconfig hci1 up ?

strace of that weird open:

open("\377\377\377\377\377\377\377\377", O_RDWR) = -1 ENOENT (No such file or directory)
write(1, "uim: Can't open \377\377\377\377\377\377\377\377\n", 25uim: Can't open ��������
) = 25

[Pavan Savoy]

When I checked upon the kernel sources, things looked alright.
Just to make sure source matches what's running on your board, Can you
check these sysfs entries for me after you boot ?

/sys/devices/platform/kim/ -->
baud_rate driver/ install power/ uevent
dev_name flow_cntrl modalias subsystem/

Among these what does baud_rate and dev_name show ?
dev_name should be /dev/ttyO1 (uart2) on panda.
baud_rate could be 3Mbps.

These values comes from populating the board-omap5panda.c @ wilink
platform devices.

It was a typo.
arch/arm/mach-omap2/board-omap4panda.c it is.

Older board-omap4panda.c had the following entry :-
/* wl127x BT, FM, GPS connectivity chip */
static int wl1271_gpios[] = {46, -1, -1};
static struct platform_device wl1271_device = {
.name = "kim",
.id = -1,
.dev = {
.platform_data = &wl1271_gpios,
},
};

This needs to be changed to,
static struct ti_st_plat_data wilink_pdata = {
.dev_name = "/dev/ttyO1", /* UART2 */
.nshutdown_gpio = 46, /* BT GPIO */
.flow_cntrl = 1,
.baud_rate = 3686400, /* 115200 for test */
.suspend = NULL,
.resume = NULL,
.chip_enable = NULL,
.chip_disable = NULL,
.chip_asleep = NULL,
.chip_awake = NULL,
};

static struct platform_device wl1271_device = {
.name = "kim",
.id = -1,
.dev.platform_data = &wilink_pdata,
};

You should be also including the following header files to reference
the platform data,
/* for TI Shared Transport devices */
#include <linux/skbuff.h>
#include <linux/ti_wilink_st.h>

Ok, it finds firmware now and seems to work. I changed udev config and installed firmware.sh (how come wlan doesn't need that for loading firmware ??).
However only one works at same time, BT or WLAN. Not that important for my purposes anyway. Thank you for help!

[Janez]

I don't know the right way to do it, but the only way I could get file is to click on right arrow next to "Post reply" and select "Show original".
Then copy base64 text to some decoder and you will get file :>
Also later I found out source for uim is already in buildroot in ti-utils package. Didn't ever try to replace this one though.

I am having the exact same issues here too. But I cannot seem to find any of the files that were attached or referenced in this thread.

Would some one be as so kind to point me in the right direction to the files required to be added/amended to get bluetooth connectivity working ?

[Pavan Savoy]

Hello All, I tried my best to get this fixed, but unfortunately could not.

Android AOSP however has all the pieces required to get this working. As mentioned before you will need 2 key pieces for BT to work.
1. TI-ST shared transport driver, driver at kernels drivers/misc/ti-st folder and platform device code at arch/arm/mach-omap2/board-panda.c
2. Uim from uim-sysfs this is available at Androids hardware/to/wpan/ti-st/

None of these as such is truly dependent on Android but the kernel user spaces changes have easily creeper into Android but finding it hard to get them to Ubuntu.

[Pavan Savoy]

Try a lower baud rate like 115200. This can be changed in the kernel where the ti-st device is added.

Thank you very much. I was able to get bluetooth working with your instructions and the TIInit file.

One thing, though, the uim program doesn't fork and just runs in the foreground, which means if there are any commands after 'uim' in your rc.local they will never run. So, I recommend using the 'setsid' command which has the effect of running it in the background. Also, uim should be running before btwilink is loaded.

# rc.local example snippet
#
# Bluetooth
setsid /usr/sbin/uim > /dev/null 2>&1
modprobe btwilink

Hi Chris,

first of all, thank you very much for these instructions.

I tried them on my pandaboard with a prebuild desktop image

ubuntu 3.2.0-1412-omap4

I was able to see the blootooth adapter and hciconfig reported "UP" and "running",

but I was not able to see and connect any devices.

I saw only one time my smartphone and a PC, but the connection was discarded.

At the same time the Pandaboard is not visible to other device.

Did you use an external antenna? 

What device did you connect? How "full" was the 2.4GHz band?

I see in the discussion

"Ubuntu Precise 12.04 - TI OMAP Release PPA Update Announcement."

these Known Issues:

* Audio is only available on HDMI - Panda Headset Audio is currently broken

* BT is not supported

Did you (or anyone else) try these instructions with the new release?

I am not able to find any updates on this topic.

Thank you very much for your reply.

Regards,

 Francesco

Ive got bluetooth an wlan working at the same time on PandaBoard and PandaBoardES.

#
# By default this script does nothing.
modprobe btwilink
uim
exit 0

Ctrl+o (save)
Ctrl+x(quit)
sudo reboot

enjoy BT on your PandaBoard !
instead of nano you can use your favourite editor..
maybe vi or sudo gedit /etc/rc.local should work, too.

I found the order of loading the module and starting UIM to be important:  modprobe *first*, then starting UIM proved to be much, much more reliable.  Pandaboard-ES.
