If i remember correctly mautz wanted me to test this with cm13 and it did not fix the bad sound quality which is also present for cm12.

But cm12 and cm13 have different kernel so it should not be the issue here?

Moreover as I understand the poor-call-quality-on-bt issue does not exist on the android cm12 or cm13 but is something to do with the combination of pulseaudio on libhybris and blutooth HSP mode.
(which is the reason that A2DP profile works without any problems)

I am using my Nexus 5 with CM13 since january instead of SFOS because of the battery drain in the latter and can confirm that BT works flawlessly in my car.

I also have to face the battery drain problem because often the CPU keeps running at 100% even with no application running...

bt calls still dont work well with my headset, very crackle and can hardly understand anything, music play is fine.

although ive built the mw vs 2.1 and attempting an update to 2.1 now, if its successful might just make an image, anyone wanting to risk it for a biscuit

removed link, it breaks your system :P

I really think that this is the solution to our problem. I guess we should add that 'brcm-patchram-plus' tool and start it as a service after having started the bluetooth service. Looks like they do it that way in asteroidos. https://github.com/AsteroidOS/meta-a...e3c3d4fed6bc93

Awesome!

Have you tried this already?

Hi to everyone, sorry for the late reply, but i am very busy at the moment...also my laptops ac adaptor got fried and my sfos sdk got corrupted. So i started from scratch yesterday and compiled a new cm13 2.1.0.10 build. I am uploading it at the moment and going to start a new thread this evening to release this build for testing. Stay tuned.
Update: Started a new thread.

I contacted 'kido' of AsteroidOS today. The 'brcm-patchram-plus' tool alone is not enough. We also need to patch 'bluesleep.c' in the kernel sources. I got some links now and will have a closer look into it. Obviously I do this on the CM12 kernel sources. I guess you use a newer kernel now with the CM13 base.
