[Q] Force music to non-A2DP BT device

So I've asked this before back when I had the Moment, but why can't I stream to BT on a non-A2DP device? No before answering the obvious, I experience the same things on the Epic that I did on the Moment where if I have music streaming, playing from the SD, etc and a call comes in, the music will automatically pause and I can take the call. Once I end the call, I the music will play for about a second or more through my BlueAnt Z9i BT and then it will revert back to the stock speaker on the phone itself. So what is preventing someone from taking advantage of that lapse of time where the music is coming through the BT and make it happen all the time? I'm sure there are COUNTLESS people who could use and benefit from this instead of buying a dedicated BT, I might be able to stream wireless from my phone to my car stereo (BT calls capable, but I cannot stream directly to it as an input), to my PC (which has BT), etc. Just throwing it out there since I've always wondered why we couldn't capitalize on the second or two and make it a normal operation. I tried to break this post into a couple of paragraphs, but the site wouldn't let me. Anyways, thanks all.

I would also be interested in this. I was able to do this with windows mobile so there's no doubt that it can be done on a non a2dp headset.

The fact that it happens, even for a second, tells me that something is delayed that is telling it to stop. Telling it to start might be in a whole different ballpark, but point is, it should be possible. I've got 3 different BT's floating around my house...one in the house sitting around on my desk, one that I always take with me in the car (gotta be safe, ya know ) and another I keep in the garage incase I get a call while I'm working on something and/or out mowing the lawn. I'd love to even be able to be following around the GF (shoot me now) while she's shopping...imaging how much better it would be to be able to play music or hear my games without people around me knowing the wiser. I don't want to have to buy and then wear a stereo headset.

App in the Marketplace called "BTSwitch" works on my devices. try out the lite version first theres a little audio flaw with the stereo music being converted to mono (i'm guessing) but then i'm an audiophile.

The only bt switch i see on the market is a widget to turn bluetooth on and off. Could you have been referring to a different app?

I'm trying this as well at the very moment. I only see one app with that name and I don't see anything referencing a lite version. My BT doesn't even like to connect while this app is installed, causing the normal BT settings to not even allow it to pair up. I had to remove the app and reboot the phone to get the BT to connect through the normal Menu > Wireless & Networks > Bluetooth Settings before it would connect again.

I know this may not be the best timing to bump this w/ all the Froyo excitement, but I'm sure myself and others would like to see this happen. I've still got my fingers crossed that maybe someone on the sidelines could help.

It's called Super Mono BT.....They have a Froyo addition as well as a "free" edition...Free addition is just a 5 day trial, after that it's 2.99. It works fine but it's not in stereo so it sounds like AM radio, LMAO. Worth a shot though just to try.

I was able to install the app, but it doesn't work for me...yet. The problem is that is requires Cynanogen Mod and I don't have that since I've (as of yesterday) flashed my phone back to stock DI18 while waiting for Sprint to send me an OTA notice to update to Froyo. I was WAY too buddy via the download available here, so I guess I wait to use this BT app. Thanks for the reply though, I look forward to being able to use it.

[Q] how to turn on audio when bluetooth connects

When I get in my car my phone connects to my stereo automatically and all and all the A2DP functions work great. Only thing is I normally keep my phone on vibrate, and multimedia sound off so I don't accidentally make noise in an inappropriate place. The problem with this split setting for sound in android is I can't just bind the two and either put my phone with audio on or off generally. Is there a way to turn off multimedia sound with I connect to my stereo and turn it back off when I disconnect? My old wm phones did this no problem.
thanks!

Check the app "car dock settings"

Perfect. Only problem is I use a generic phone holder and usb power supply... how does it know its docked?
*edit* solution might be found... the same people who make car dock settings have bluedock 3 which does the same using the bluetooth profile (similar to Advanced Audio Manager once combined with "car dock settings")
I also found Toggle Settings|Profiles Lite which might work... I will try them all and report in case anyone ever asks the same question and falls on this thread
**second edit, reporting on the apps**
Toggle Settings\Profiles Lite works great. It takes up about 1mb ram rather than 150k compared to car dock settings and another 100k for bluedock 3, but its a free all-in one package that is MUCH more powerful and versatile. With the lite version you get 3 "Rules", I used one to make my car settings based on connecting and disconnecting from my stereo.It allows me to change just about anything on connect\disconnect and lets me create two other rule sets I could want (and as many as I want if I pay for the full version). I strongly recommend this app to anyone and everyone who wants to have automated location\connection\event\time based actions. The only down side is it takes about 15 seconds for the bluetooth to register as being connected (so be patient), but I think this is part of android because wifi-related events are instant.

Routing notifications through car bluetooth

Hi all --
So my 6p, Pure Nexus Rom, is Bluetooth connected to my 2014 Cadillac SRX. Everything is checked off in the settings for the connection -- phone audio, media audio, and contact sharing. I make and receive calls fine. I can play music over the Bluetooth connection. But I have a program called "Out Loud" that is supposed to read my texts and messages over the Bluetooth connection, and it doesn't seem to work. Waze directions won't read over the connection either. However, if I'm streaming music from the phone to the car, out loud and Waze DO work. It interrupts the music to read texts, etc. But if I'm listening to the radio or an SD card plugged into the car's SD card slot, nothing. So clearly the notifications are working if I'm streaming music, but otherwise, no go. Shouldn't the "Media Audio" connection cover all my phone's media audio, not just streaming music? Does anyone have any idea why it's not and what I might be doing wrong? Thanks so so much for any help in advance, I truly appreciate it.

Not sure if it's supposed to work any different from mine (2008 Ford Fusion), but the only time I hear anything is if Bluetooth is connected and my radio source is set to Bluetooth or if I receive a call and my phone is paired to the vehicle, then it'll override anything that I'm listening to allow me to answer the call through my car. I'm assuming this is still similar in nature to your vehicle. Maybe the app has an option whether you'd like to route sound through Bluetooth or your phone speaker instead (just like in the Waze app)? If it doesnt, maybe the dev could consider adding this feature.

Yeah, it's odd. I was on a diffeent ROM (had to switch because I was getting a lot of hot boots), and the texts were read aloud through the Bluetooth no matter if I was listening to the radio, or streaming music from the phone. So I'm confused why it's not doing the same on Pure Nexus.

It's all about the different bluetooth profiles. The music streaming portion of bluetooth has no real priority, it's up to the radio to decide if you're going to hear the stream. Now phone calls, on the other hand, is a different portion of the connection. The radio allows the phone to interrupt whatever you're listening to. For me also, if you hit the google voice search on your phone, it'll interrupt the radio to use the car's built in mic and speakers to interact. With that in mind, we know it doesn't just have to be phone calls per se., the voice search interrupts the radio (or whatever other source) just fine. The question becomes that of figuring out what apps you can utilize to cause the bluetooth connection to recognize an interruption. Personally, I'd love to see it for Maps given the scenario of my listening to the radio and not hearing the turn-by-turn prompts since I'm not streaming from the bluetooth source and the phone obviously won't play it out loud. I've done some research (of course as a non-developer) and have found that it's such a low-level operation that most developers don't bother with trying to make work. The only reason you happen to hear notifications while streaming is because you've actively preselected the option on your radio to hear whatever the phone wants to push out in its entirety.

Yeah, I just can't figure out why, with one rom, all my apps seemed to have the capacity to have the Bluetooth recognize an interruption no matter what I was listening to, while on Pure Nexus, as you said, I have to have selected streaming phone music in order for those notifications to play through the Bluetooth. I wish I could figure out how to give Out Loud that same priority. In theory, it lets you pick the audio stream you want to try ("Music, Voice Call, Alarm, or Notification"), but none of them work for me. Very frustrating.

From my research it appears:
1) it's a recognized quirk that has something to do with incompatibility with one of the protocols that Android uses.
2) when using BT & 'Radio' setting (i.e. listen to radio in car): the nav voice commands will either be mute or fade-in.
3) when using BT & the 'Streaming Media' setting (i.e. play streaming music from your mobile): the nav voice commands will work as expected
4) This or this may or may not help.
5) IOS has this issue also[/QUOTE]

Samsung S8 Crackling Bluetooth audio and Bluetooth Codecs

Hi Guys.
I've seen a number of posts on this subject so here's my story and my experience thus far.
I've been using an iPhone 7 since it came out. I've been very happy playing music in my car (Fiesta with SYNC2 system) all this time. My significant other has been using an S8 for some time, and her music always sounded 'crackly' (for lack of a better word) in the car. I thought this was just her Spotify or something.
2 Days ago I bought my own S8 and I had exactly the same issue.
Now from some research I've been able to deduce that this is down to the Bluetooth Codec the phone uses. I changed mine to aptX yesterday and the music quality was great. Didn't sound like a 200KB MP3 downloaded in the early 2000's anymore.
However...
Last night I had to reboot my phone for reasons, and the developer options reset completely, which I believe is normal behavior. But now I can't set my Bluetooth Codec anymore? I change it, the moment I close the menu, it reverts back to SBC. I tried this with Bluetooth off, Bluetooth on and not connected, Bluetooth on and connected, no joy. It keeps reverting. Same goes for all the other Bluetooth settings (i.e bitrate).
So gentleman I ask you humbly, wtf? Why does the settings not stick and is this normal behavior? Is there a way I can force it to use AAC or aptX once more? I really have come to enjoy this phone but playing music in my car is a very very big factor and since AUX and USB (can't seem to play Apple Music/Google Music via USB) isn't an option, I'm stuck with Bluetooth.
Thanks in advance,

Have you made sure dual audio is disabled???
If not, go to Bluetooth, turn it on, hit the tripple dots in the top right and tap on "Dual Audio"
Make sure it's off and now try changing to AptX or whatever codec works best for you.
Disable / re-enable Buetooth and see if it sticks. (Try rebooting too)
Also, Bluetooth codecs will automatically change if the device you're connecting to doesn't support your choice of codec.
Keep me posted

Hi Corey,
Thanks for the response. Unfortunately, the above didn't work Dual audio was disabled, I enabled it and disabled it again. I tried changing the codec and bit rate but the result is the same, the moment I close the menu or turn on Bluetooth, it reverts back to SBC and Best Effort bitrate. I should mention that when I turn on the Bluetooth, it doesn't connect to anything, the only paired device at this point is my car.
Interestingly enough, if I don't close the menu but just hit the middle button, the settings will stay as is and the audio is great. What I haven't tried yet is closing the menu after a 'good' connection is made to the car. It may be that the setting sticks but the menu says otherwise. But I can definitely confirm that if I close the menu and then connect, the audio is garbage.
As for the compatibility of the car's Bluetooth, well it's a Ford SYNC2 system which from what I can see is actually quite basic. I am starting to this the problem isn't as much the codec, but rather the bitrate at which the phone is playing/sending music across the Bluetooth.

I'm not gonna' lie, I'm not very impressed by the Bluetooth on the S8... or Bluetooth in general.
It's lousy most of the time, mine always distorts and especially around emergency vehicles... (Could be interference from their coms???)
If possible, just stick to good 'ol copper wire
I can't imagine wireless audio not ever being interfered with and will always stay wired.
Also, try a music app called Poweramp.
It has many settings involving latency etc. It has a trial for 2 weeks and is worth EVERY penny if you decide to buy IMHO.
Try the build version first, if that doesn't have settings that you need, try the alpha version.
It has lots of latency settings etc
I'm guessing higher latency = better results as it has more time to be pushed over BT before the sound is reproduced.
I'm probably wrong though.
Can't beat lots of settings tho aye.

Morning Corey,
Yeah so my situation at the moment is to have my old iPhone in the car at all times as a glorified bluetooth player. I've also gone out and bought an auxiliary cable for when the iPhone's battery dies on me (happens more often than one would think). And to have a charger for the iPhone, charger for the Samsung and aux cable for the Samsung all plugged in becomes really messy.
It must be something to do with the Bluetooth 5 feature. I don't know what version the iPhone is (cba to check) but it works like a dream.
Wish we had some form of backwards compatibility or a feature to force an older version with Samsung. Just sucks buying a phone which is really not cheap in ZA just to have the music sound like a 300kb MP3 played on Winamp with the treble bars turned up all the way.
I'll try out the app you suggested mate, thanks!

No worries and if you are referring to a USB cigarette lighter charger/USB charger then try the multi-cables.
Try one of these: https://www.amazon.co.uk/Poweradd-L...coding=UTF8&psc=1&refRID=59QBSADVWM0NKGZGTQ4K

sorry to drag up an old thread, i have the same problem ( sync2 too) and it is same issues. I have noticed that even though its bad its tolerable bad. then i add my samsung watch and becomes awful.
did you ever figure the issue out? i feel its the sync2 causing some kind of problem

Developer Mode Bluetooth setup not sticking... any solution?

As the title says everytime I setup my preferences in developer mode it reverts back after every song.... Is there any way to fix this?

A lot of that will depend if your headphones can support those bit rates. Its 50% on the headphones. Could you set those options on another phone with this headset? Also, did you stop the music while changing bit rate?
EDIT: I just tried it on my phone with some cheap bluetooth headphones. The3 settings dont stick but I also know that these are cheap headphones that will not support some of the advanced features.
EDIT2: When I use a better set of headphones, with Apt-X for example, I can change the settings and they stick.

Thanks for the reply will play with the settings and see

Nothing works

I have also run into this issue and reverted back to stock because of it plus other reasons.
You could solve this issue (errr work around it) by using Tasker and configuring Tasker to toggle the settings in Developer settings for you when a BT device is connected. I haven't done it, but I know it's possible as Tasker can do almost anything with Root access.
Good luck.

Probably... But I don't know how to use Tasker ?

I have the T-Mobile edition. I had the same issue with my BeatsX, which use AAC. Audio was pretty bad.
I didn't find a solution to the problem despite researching for days, but when I flashed the international OxygenOS the issue seemed to have fixed itself, and my dev options show the headphones using AAC like it should.
I don't know if this would fix your issue, but that's my story with the same prob. Setting for example the AptX codec with my BeatsX doesn't work because, iirc, the codec isn't support by the headphones themselves. So the setting gets reverted. Maybe your headphones only support that specific codec as well.
