Andy, how do you usually test bluetooth with your kernel? Just want to make sure we're not missing anything.

Normally with uim and then bluetooth UI on Ubuntu desktop.

There were a couple of patches missing, tilt-3.4 == 448be0e3981852c8b7032c5d7d51747a1187b774 is working OK at least for scan.

Notice bt firmware now lives down /lib/firmware/ti-connectivity (it has for a while but just making sure) and on my PandaBoard ES, it needed TIInit_7.6.15.bts rather than the TIInit_7.2.31.bts that was in my rootfs.

Bluetooth doesn't work on Panda 4430, can't be enabled in settings, can't pair Bluetooth headset either.

Great, should be getting a new package in a few hours and will verify it again.

Yeah, we got the correct firmware already, guess it was just at the kernel side.

Please refer to attachment to get serial log output.

For the behaviour in comment #16, it can be observed while another paired Bluetooth device turning off. The procedures are:

1. Pair Panda 4460 with another Bluetooth device, such like a Bluetooth enabled laptop or a Bluetooth headset;

2. Turning off Bluetooth function on that Bluetooth device, for example, disable Bluetooth on laptop or power off Bluetooth headset;

3. Panda 4460 board hangs.

Please refer to attachment to get the serial console log output.

For Panda 4430 board, with the same Linaro ubuntu pre-built image as Panda 4460 board:

With latest hwpack (latest lt-omap's kernel) I can successfully use bluetooth, to scan devices and also able to use it with a BT headset. The issue while transferring files is not specific to panda, and it's covered by bug 872044.

Marking bug as fix-commited as the basic functionality on the hardware level is working as expected on panda.

Confirmed on pre-built image:

Now under HDMI+Unity 2D mode, Panda 4460 board can use Bluetooth to pair another Bluetooth device, for example, a Bluetooth headset.

Observed same behaviour as comment #18, system hangs after I shut down another paired Bluetooth device (my laptop). This happens on Panda 4460 board with Linaro ubuntu image:

No sound can be heard via Bluetooth headset, although it can be paired successfully, and the device can be shown in "Output" section of "Sound" settings.

Board tries to search for device, when tried to pair with another device it freezes. Log same as comment #22

The freeze observed at #22 is not related with bluetooth (at least I hope so). That's probably more connect with the PowerVG SGX driver. Are you using unity-3d while running this test or unity-2d?

Now regarding comment #18, that might indeed be an issue related with bluetooth, probably happening when stressing the bt interface. Mind opening another bug for this behavior? This is just because this bug is more related with the basic functionality, which is already in place.

addition to comment #30 the board freezes after listening to music over BT headset for a while.

Bluetooth headset can be paired successfully with the board, and it also can be shown in "Output" section of settings menu. However, first, there is no any sound be heard after music started to play; second, system hangs around 1 minute later after music started playing.

Please refer to attachment to get detailed log output. The display mode is HDMI + Unity 2D.

Reboot the board and try it again, now it can pair with another Bluetooth device - my laptop successfully. However, when try to play music via Bluetooth headset, no sound be beard.

Bluetooth feature now looks unstable and may need to investigate more.

Log in serial console after click the test sound button and then click front left button, refer to attachment.

Many "hci0: type 2 len NN" flushing in console, after that, no any sound could be heard. However, after the first click on front left button, sound can be heard, but only that 1 time.

This is blowing up on graphics side, not obviously related to bt

Normally there's not much idea to be had from that, but yesterday we found a problem with one of the Androidization patches that causes crashes when under memory pressure. It's an mm subsystem locking race related problem giving pernicious results.

If you try again with a kernel from tilt-3.4 b71a84254eca700ad8cdf3e3735488cde746f2ac or later, it'll be interesting to see if the problem is still coming.

The Bluetooth pairing with Motorola S305 headset failed and system hangs. Please refer to attachment to get serial log output. I tried twice but got same behaviour. The action list is:

1. Click "System Settings" icon on desktop left side panel;

2. Click "Bluetooth" in "Hardware" section of "All Settings" screen;

3. Power on Motorola S305 Bluetooth headset & wait around 30 seconds;

4. Click "+" button to add a Bluetooth device, follow instructions;

5. System hangs.

However, in this condition, keep Bluetooth headset is ON, plug out board power cable and plug it in to reboot, then enter the Bluetooth settings, you will see the headset has been paired there. Now click the headset name (Motorola S305) on left side of Bluetooth settings screen, then turn "Connection" ON by clicking it on the right side area. After the "Connection" be turned ON, the Bluetooth item will be shown in Sounds settings, and that A2DP one can be used to listen music from rhythmbox, and it works well.

Bluetooth pair & headset (Motorola S305) work well on Panda 4460 with Linaro ubuntu pre-built image:

Motorola S305 Bluetooth headset can be paired and works well. However, after power off the headset, the board hangs. Please refer to attachment to get serial log.

Are you still able to reproduce this issue with the 12.09 RC1 image?

@Ricardo, Motorola Bluetooth headset S305 now works well. Observed on Linaro ubuntu image:

https://snapshots.linaro.org/precise/pre-built/lt-panda-x11-base/329/lt-panda-x11-base-precise_ubuntu-desktop_20120924-329.img.gz

However, file transfer feature is still unavailable, but there is another bug for that:

https://bugs.launchpad.net/gnome-bluetooth/+bug/872044

We can consider this bug as "Fix Released", also, if necessary, we can raise a bug on our side to trace the file transfer failure since bug 872044 was reported by outside person.
