[Jawbone ERA] HFP features not working with Bluez5 when phone initiates connection

[Tony Espy]

While debugging some re-factoring work on the ofono upower plugin, I noticed that I wasn't able to answer or terminate calls using my Jawbone ERA headset. I bought this headset last year, and although it's an older model, it's spec sheet states that it supports HSP 1.1, and HFP 1.5.

I can pair the device with my krillin, and it properly auto connects ( note, this seems to work better than my iPhone ). In-call audio works for both incoming and outgoing calls, however I get no ringtone in the headset and as mentioned above, I can't answer or terminate the call. I've verified on my iPhone6, that the headset works. In addition to a ringtone in the earpiece, the headset also announces the incoming phone number.

From looking at the ofono debug output, I'm never seeing a new HFP connection occur. I noticed as the upower plugin uses a foreach_atom (HFP) style call to update the battery indicators on all attached HFP devices.

I've tested this extensively on krillin, running rc-proposed:

phablet@ubuntu-phablet:~$ system-image-cli -i
current build number: 205
device name: krillin
channel: ubuntu-touch/rc-proposed/bq-aquaris.en

version custom: 20151111--36-46-vivid

I've also tested on mako, rc-proposed ( #317 ).

For reference here's the versions of bluez, ofono, and PulseAudio on the device:

bluez 5.36-0ubuntu2~overlay1
ofono 1.17.bzr6908+15.04.20151203-0ubuntu1~awe3
pulseaudio 1:6.0-0ubuntu9.11

Did a first look and it seems that your headset initates the connection and wants to connect on HSP

Not sure why but that is the reason why you can't

- control the call
- don't hear any ringtone as long as the telepathy-ofono service changes didn't landed to do this over A2DP rather than switching to HSP/HFP already when the ringtone is playing.

@Simon

It works fine with my iPhone6, and has worked properly before with Ubuntu...

[Tony Espy (awe)]

Re-tested to check that initiating the connection from the phone ( ie. by doing a fresh pairing ) doesn't make a difference.

Nothing has been upgraded on the phone, same image used as when the bug was reported. No difference after connecting from the phone; syslog attached.

[Tony Espy (awe)]

Re-tested with the last stable image ( ie. bluez4 userspace ) on krillin, and the headset functions works fine regardless of which side initiates the connection.

Re-tested on krillin, rc-proposed #231. Same result, my Jawbone only works as a headset. Same result on arale ( rc-proposed, #220 ). On mako ( rc-proposed, #331 ) I couldn't even get the headset function to work.

[Tony Espy (awe)]

Re-tested on arale ( rc-proposed - 258 ) with bluez 5.37 ( from silo 39 ) and I'm able to terminate a call from the headset.

Re-tested on krillin ( rc-proposed - 419 ) with bluez 5.37 ( same silo ) and I'm also able to terminate the call from the headset.

Note - I also installed pulseaudio from silo 47, which fixes a regression in rc-proposed on arale and krillin.

[Tony Espy (awe)]

Note, it turns out that if the headset initiates the connection, then the HFP features work. It's only when the connection is initiated from the phone ( ie. when first pairing the device ) that the HFP features fail.

To reproduce easily:

1. Goto to settings & forget the device if previously paired
2. Pair the device
3. Make a phone call
4. Try to end the call from the headset

@Tony: With your last comment: BlueZ 5.37 doesn't fix that problem too? Or do you still see this with bluez 5.37?

[Tony Espy (awe)]

@Simon

Pretty sure my results reported in comment #11 were using the silo, so 5.37 doesn't resolve the problem.

I just re-tested on arale ( rc-proposed, 350 ) and still see the same behavior on the initial connect of the headset. Unfortunately, I can't seem to get the headset to work at all now with the latest rc-proposed image.

I'll retry on krillin later today.

Reduced priority for Ubuntu Touch bugs.

[Daniel van Vugt (vanvugt)]

I assume this was released...

[Daniel van Vugt (vanvugt)]

Oh. Except comment #13 says not.

[Daniel van Vugt (vanvugt)]

Ubuntu Touch is no longer supported.
