Bluetooth problem with IOS 10

[BergeracMatt]

Hi Halle,
I’m using a desktop bluetooth speaker/mic and it has been working well with both my iPhone and iPad – until I upgraded the iPad to IOS 10. Since then, the bluetooth speaker plays and records nothing when connected to the IOS10 iPad. It acts like the speaker and mic are both muted (they’re not)
The same Xcode project, installed to the IOS9 iPhone, the bluetooth works fine. I’ll include startup logs from both the IOS10 iPad and IOS9 iPhone.

I have a separate part of the app which records and plays audio through the same bluetooth speaker – that works fine with both IOS9 and 10.
It would take me about 15 minutes to change the project code and capture logs again with the standard acoustic model if you think that my custom dynamic model is somehow playing a part.

Thanks
Matt.

First the failing IOS10 iPad (then the IOS9 iPhone later)

Hi Matt,

Check out the recent bluetooth discussions here in the forums and the FAQ entries on BT compatibility methods and support in order to get a headstart troubleshooting this, thanks!

[BergeracMatt]

Thanks once more for the quick response. I had come across those compatibility options but hadn’t tried them because the hardware was working.
In my case, setting disablePreferredBufferSize got it working. I’ll add some info into the “bluetooth device results” thread shortly.
BTW – I had framework version 2.5.01 and it doesn’t have any of those compatibility properties even though the docs suggest 2.5.x does. I upgraded to 2.5.03 and I was able to set them.

In terms or releasing an app to support as wide a range of hardware as possible, do you think I/we should set all 3 compatibility properties to true? or give users some way of selecting all 6 combinations?
That might be impossible for you to answer – maybe a better question would be – what is the downside of setting all 3 options to true?

[Halle Winkler]

Hi,

Glad that helped. I am going to take in the data on this for a little while but my current suspicion is that the majority of cases will be fixed by disablePreferredBufferSize and that maybe a minority will also benefit from disablePreferredSampleRate, and so far I haven’t heard of any that needed the channel override to be functional. On the assumption that it will help the most users while making the least changes, my recommendation would be to start by using disablePreferredBufferSize, pay attention for reports of issues with BT devices that might confirm that the other setting is also needed, do your own tests of performance (the interesting performance question is CPU usage when there is absolutely no speech or anything perceived as speech) and let me know about them in the general BT thread, and always start your troubleshooting process by upgrading to all current versions. It isn’t humane UX to give users multiple choices for managing their own device compatibility – I would either have one “Bluetooth compatibility mode” switch that turns on as many of the settings as your testing has demonstrated it’s reasonable to ship with, or simply set them on with no switch and carefully test whether there is any negative impact on your use case when Bluetooth isn’t being used.
