Now Bluetooth works fine?

Inviato dal mio Nexus 5 Cataclysm 5.1

Working just fine for me buddy :) Haven't gotten a connection drop or cut off for about 2 hours (connected to my car). :) Very happy with this update. :good:

---------- Post added at 04:27 PM ---------- Previous post was at 04:10 PM ----------

I would use the word "solid" after some days using such a complex software, not after a few hours...

I am on the 24 th build and i found only a few things
  • The date format that is passed to apps is always in the order mm dd - but the date separator is ok. Here in germany it should be dd.mm but actually it shows up like mm.dd
  • Video streaming from my Sat=>Ip server does not work correctly. In CM12.0 everything was ok but now i often get no picture. Video format is always H.264 (1024i or 720p) with MX player.

I also tried the 23th build before but there i had the problem that the display had a slight green tint and adjusting it made the graphics stutter. With the 24th build (clean install as always) my display was "paper white" b default as it should be, so i did not have to adjust anything. Strange that i can not find anything about this in the change log...

The reason i said "solid" is because i haven't been getting some of the problems that some people have been mentioning here. Just once did i have a minor problem with my BT. But that was caused by human mistake or error. My mistake actually. And I kinda agree with you when you said "I would use the word "solid" after some days using such a complex software, not after a few hours..." If you know how your phone reacts to every update of a nightly or anything.... You actually see and feel the difference. Even though just having the build a couple of hours. Now for the part where i would say BATTERY LIFE, now that is for sure a different story. ;)
Just wanted to add this too... One of many problems that 5.x.x.x lollipop has is Google play services. That too is something to look out for in these new next nighlies to come.

Hi Everyone,

CMUpdater is not displaying the latest nightlies for the past two builds. Anyone else experiencing this?

Cheers,
Steve

I agree! CMUpdater seems wonky. Even CyanDelta kinda had a prob when i tried using it (Maybe Cyandelta app problem). It would get stuck on 5% download. :( So i reverted to the old way that always works.... Everything through @Phil3759 Custom recovery is just simply the best way for me. Mad respect for that Dev!

I can confirm that my bt issue has also been resolved with the 4-26 build.

Hopefully with all the changes that were stated on 26th build changelog, CM team is really starting to acknowledge and show improvements in their work on every build. I'm for sure and very glad that my BT is working 100% for a change :D: on CM12.1 5.1.1:good::D I'm a Happy camper right here! LOL

Skip Music with Volume Keys is still buggy. Sometimes it works but most of the time its just increase the volume (even if I try to replay the track - what is done with the key für decreasing the volume)

I can confirm that my bt issue has also been resolved with the 4-26 build.

I'm now running 20150426 as well and still have the BT reconnect issue. This is triggered by disconnecting the speaker side of "Media audio". You then can't stream anymore, unless you cycle BT off/on on the phone side.

Will try to generate logs as well. Should I post the logs here or somewhere else ?

Cheers

I for one have a $#177y way of using my battery here on my Gt-I9505. I don't play games is one, 2nd i only use this phone for calls and messages, emails (Mostly calls) and data etc the regular crap... and use the phones BT to connect to my car's head unit ;) I get by at least 10 to 11 hours on a regular full charge. Not much but it does what its suppose to do as a phone. :) Now with my Note 4... that's a different story. Been abusing the hell out of it since i got it. LOL :p For me that's a Phone that has a very wisely made battery to be recon with. Lets just not compare it with a One+. Now that's a phone that has a great battery life. Wish i had one though :)

EDIT: Any of you guys still on the April 22nd build? Was the Silent mode toggle present for you guys?

I have tried disconnecting from one BT device and connecting another and back again.... Seems to work OK, the reconnect didn't work last week..... As for the BT disconnects, can't comment yet, bet will play some music, to check..... Getting better, the rest of the ROM seems pretty solid for a new build..... :)

Does not work to me. But I didn't see any correction on the today's changelog. I hope it will be fixed soon.

    This is going to be a slightly long post. :) I started digging in to the Bluetooth problem, because it's been bothering me since, well, forever, both on Galaxy S4 (I9505) and S2 (I9100). Turns out its quite a mess with multiple moving parts, so to speak.

    First thing I found is that the Broadcom vendor library for Bluetooth is missing an implementation for a function called "ssr_cleanup". Our S4 uses Broadcom, so this is definitely an issue. The implementation is missing all the way upstream in AOSP sources.
    File in question: https://github.com/CyanogenMod/android_hardware_broadcom_libbt/blob/cm-12.1/src/bt_vendor_brcm.c (Google: https://android.googlesource.com/pl...libbt/+/android-5.1.1_r4/src/bt_vendor_brcm.c)

    This missing function causes the following error in the log:
    Code:
    E/bt-hci  ( 3577): Num consecutive HCI Cmd tout =2 Restarting BT process
    E/bt-btif ( 3577): bte_ssr_cleanup
    F/libc    ( 3577): Fatal signal 11 (SIGSEGV), code 1, fault addr 0x0 in tid 9919 (bluedroid wake/)
    I did my own implementation for this, mimicking the ssr_cleanup in Qualcom BT vendor lib. Compiled, replaced /system/vendor/lib/libbt-vendor.so and "Fatal signal 11" disappeared from the logs. Just as expected.

    However, this is NOT what causes the random BT disconnects. ssr_cleanup is just what happens after BTU HCI commands timeout twice consecutively.

    When BTU HCI commands time out twice consecutively, the following takes place:
    • ssr_cleanup is called
    • wait 20 milliseconds
    • "Killing the process to force a restart as part of fault tolerance" (i.e. the Bluetooth process is killed)
    So, just to test, I removed killing of the Bluetooth process from the code. Compiled, replaced system bluetooth.default.so, and ssr_cleanup/killing the process no longer happens.

    Of course, this didn't help, because things have already gone wrong when the HCI commands are timing out.

    As a note: at this point, the Bluetooth connection was stable for a random length of time (first test 3 hours, this morning a few minutes). Once the HCI commands start timing out, the connection will become unstable, possibly disconnect from my computer/car's handsfree, and it will remain so until Bluetooth is restarted. Of course, with the modifications I had implemented, the BT process was not automatically killed/restarted.

    I googled for "BTU HCI command timeout", and found that it's a common problem for at least Samsung Galaxy S3, Nexus 5, and HTC One. On StackOverflow, somebody commented that: "Of note, with specific code, the Galaxy S4 will automatically reconnect when this occurs, leading us to believe there is an issue in the BLE stack that Samsung identified and developed custom handling for." So Samsung may have implemented a way of quickly restarting the BT process without interfering with the ongoing connections. I have noticed when using I9505 GPE 5.0.1 that sometimes the BT connection becomes unresponsive for a second or two, but then just resumes without disconnecting.

    So what this boils down to is:
    • We need to find out why BTU HCI commands are timing out, and can we avoid it?
    • Figure out how to recover from this situation without breaking the Bluetooth connections
    • Or at least quickly connect/disconnect when faults occur
    Before these problems are figured out, I doubt that CM or AOSP will have reliable Bluetooth on Galaxy S4.
    Bluetooth works just fine for me on stock TW or GPE roms, but I really like CM much more because of its smoothness and functionalities...

    I have thought of replacing the CM Bluetooth with GPE implementation. However, I do not have the skills for that. Simply replacing the BT-related .so and .apk files ended up in loads of FCs.
    @AntaresOne Any idea how to start fixing this BT?

    you guys need to realize that the handfull of people contributing for jf have moved on from jf. we get no benefit from this. lots of complaining not lots of logs

    Be assured that your work and join in discussion is appreciated not only by jf owners.
    [emoji4]
    jactivelte and other Qcomm devices profit when competent people do real coding in Gerrit like you do.

    When comparing the commits of (not sure if still maintainer?) AntaresOne:
    http://review.cyanogenmod.org/#/q/owner:"Mattia+D'Alleva+%3Cantaresone%40antaresone.eu%3E"

    with

    dcd:
    http://review.cyanogenmod.org/#/q/owner:"dcd+%3Cdcd1182%40gmail.com%3E"

    the difference in numbers of merged commits is jaw-dropping [emoji6]


    Agree with you that output of logcat is more helpful than words like "X or Y not working".

    Please do stay.

    ThumbsUp button under every post is free to use in case you're in the mood to show appreciation.

    Or started own projects based on CM like "Optimized CyanogenMod 12.1 builds". I still dont get it. Why do we need a optimized Build. Why can't people just contribute those "optimizations" and fixes to the normal CM repo, so that everyone can profit.

    So, the point of sending patches to gerrit seldom makes some people acting bad saying that somebody or his work are useless. I have never been a fulltime developer with all the other things I have to do outside jf and while jf tree is practically done. You started comparisions between me and another maintainer, now seriously, do we need that? What can you get from it?

    Some people still think that CM maintainers are paid, so I'm basically nothing more than a thief since I'm committing once in a period. Now dear people, CM maintainers are NOT paid. I am in Italy, not in the U.S., situation is very bad and quality of life terribly decreased. More than "losing time" on something which doesn't give me any form of payment I focus in working on what can really give me some money back, but I'm glad to commit on gerrit when needed.

    If the dev(s)/maintainer don't read this thread (busy with work and personal life, summer etc.) is defined as useless, right no?

    Optimized ROM is how I personally want CM, and 99/100 things inside can't be added to official CM due to how these things work. I am free to do whatever I want.

    "Why do we need", remember you're not paying for what you can find here. You can't say that in respect of me, my team and whoever spends time doing something for the community. Very bad, rude and offensive. @feydakin: you used that ROM and now saying that is useless, nice job...

    How many times I asked for a log and didn't get anything? I always checked this thread daily and daily wrote here before half of June. Even if I'm not writing I'm still always checking. Don't be bad and arrogant with me only because @dcd1182 is here, but keep intact your common sense, respect in me and seriousness as it was before. I have never been arrogant or disrespectful with you.

    Lastly, just for the chronicle, my XDA activity decreased a lot since June (I have a personal life, don't know about you) and I'm sorry if I missed many messages.

    Close OT.

    Hi guys, which has been the most stable nightly so far? Thanks

    Hello,
    I would install the most recent, always contains latest patches which are not available in the older builds

    EDIT: I saw the other user said that every build after 4 August has issues with LiveDisplay. So install that one, I can't check myself if it's actually working or not at the moment
