Georg,

Thanks for your response. I've never heard of that option before, so I added it. Up until this point, I've been just trying to figure it out. I've not found any documentation on how to accomplish this.

So, I added that parameter. My results are similiar to results I've achieved before. No crashing this time. (But it's not 100% reliable either).

I placed one call, and everything worked (audio in out of the computer). I've been able to get this to happen once in a while.

I disconnect the call from the phone. I placed a second call, there wasn't any audio, and my logs scroll like this:

[ 1052.809382] Bluetooth: hci0 SCO packet for unknown connection handle 2

[ 1052.809964] Bluetooth: hci0 SCO packet for unknown connection handle 16384

[ 1052.810563] Bluetooth: hci0 SCO packet for unknown connection handle 48

[ 1052.817712] Bluetooth: hci0 SCO packet for unknown connection handle 1

[ 1052.818544] Bluetooth: hci0 SCO packet for unknown connection handle 1

[ 1052.819508] Bluetooth: hci0 SCO packet for unknown connection handle 1

[ 1052.820332] Bluetooth: hci0 SCO packet for unknown connection handle 1

I disconnected that call. I placed a third call and all audio came out of the phone.

In a few previous tests, when this happens I see that ofono still thinks I have a voicecall.

So, I probed dbus to verify this:

qdbus --system org.ofono

As soon as I did that, the VM shut off. (No kernel crash - just instant off - I've seen this a few times)

Greetings,

I've been working on getting a HFP working with bluez and pulseaudio. I'm running into an assortment of issues- I don't even know where to begin!

To set the stage, I'm running the latest version of bluez (5.33) pulseaudio (6.0) and ofono
(pulled out of git). I've compiled everything from source.

Using PA and Bluez, I have audio sink working. So I've verified several components at this point.
I can connect the HFP. Once I start making calls, is when things start to fall apart.

(BTW, this happens with ofono 1.15, and 1.16 as well)

So, as I'm writing this, the last two times after booting (debian jessie), connecting, and dialing, the system reboots. I've tried looking at debugging the kernel crash, and I've just not got very far.

I realize no one can tell me clearly how to fix this, I would appreciate some suggestions, or ways I can continue to debug this.

Ultimately, my goal is to put this on a raspberry pi for a car stereo. At the moment, I am just trying to get a proof of concept working.

Thanks!

Hi Jason,

do you use headset=ofono as parameter to module-bluetooth-discover in default.pa?
Otherwise things will go wrong, although I would not expect a reboot of the machine.

Regards
Georg
