[Q] Bluetooth and Multiple connections - Galaxy S 4 Q&A, Help & Troubleshooting

Hello.
I am using my S4 in car.
It connects at same time to my car hands free (Audi MMI) with Call Audio profile and it connects to my A2DP Music receiver (connected to my car IPOD cable) using A2DP profile.
This dongle supports also Call Audio profile but I have paired it using only A2DP.
Connections are good and phone always connect to both without connection issues.
Sometimes (often) when it is connected to both devices, music and sound stop playing (the player is going on with playing and with time counter but I can't hear any sound from car or from phone speaker).
If I disconnect car hands free, music starts playing from car audio speakers.
If I reconnect car hands free again, music stops playing.
When this happen, the only way I found to solve is to restart the phone and then all is ok (phone hands free and music streaming).
I have the problem with 4.3 but it was the same also with previuos 4.2.2 android version.
I think it is a phone problem since restarting always solve it.
Someone had the same problem or has any advice?
Thank you
Chris

Audio problems when using bluetooth headset while streaming

Hello
My problem is as follows. I have paired my Motorola S9 headset with my A7 tablet without any problems. I can listen to music in my sd card with no problems but when I try and listen to music from pandora it just keeps getting cut of like if it were buffering. Does not happen with normal headsets. Tried different wifi networks and does it from all of them. On other interesting thing was that on my mifi device it would not connect as long as my headset was enabled and connected through bluetooth. As soon as I disconnect the headset it works fine.
This happened with Dextermod 1.2 as well as 1.3 with the bluetooth fix enabled.
Any ideas?

[Q] Spotty Bluetooth Performance?

I'm able to connect my Atrix to my JVC double din in car stereo system via bluetooth and it connects and pairs just fine. The problem I have is that the music "skips" or loses sound every few 20 to 30 seconds. It plays the whole music file but seems to drop out here and there. My old tilt 2 played on this same jvc beautifully using bluetooth. But the Atrix cant keep up? It happens no matter if I play music files through the stock android music player, or Power Amp player. What gives?
I also have a JVC Kw-Avx810 with bluetooth adapter installed. I have the same problem, for calls it works perfectly but for music its a bitt frustrating to hear music skipping each 30 seconds. Sometimes I am able to hear the music without skipping and that happens when I first play the music on the phone and while the music is playing on the phone I turn on bluetooth on the phone and the after 10 seconds it begins to stream the music to the Jvc Unit without any problem. I do that every time that I wanna hear music on my Jvc unit. Havent had any more issues so far.
I use it for my ford sync and at times it will do strange things that my nokia n95 never did but for the most part it works well...

I had a similar problem when I had my streak. It was because I was pairing Audio with one device and bt phone with another. If you are doing this it will cause that. I use my Sony stereo just fine, will disconnect occasionally, but quality is great.
I use my atrix with my prius, and so far so good.I haven't had disconnect issues yet.
I think it's something JVC could probably fix with a firmware update. The atrix streams just fine to both my Sony and Kenwood headunits.
I have the same problem.

The key terms: "Usable but not stable" , although it was not tested with Atrix, it is evidenced on both HTC and Motorola phones.
Great move JVC .. you've made your product useless to me and tarnished your reputation at the same time. Couldn't get your guys to write a new firmware ... Cant get me to buy another one of your products.
The same looks very like it will be true with Motorola's Andriod phones. Both JVC and Motorola will soon be wiped off my present or future ownership map. Woooo
Mine drops out/ goes silent / loses bt connection about once every 8-12 minutes when connected to my sony head unit (mex-bt5100). I turn off bt then back on, then restart my streaming radio.

I have a jvc double din unit too. I don't experience any issues with audio... however the phone is a bit garbled when connected.
Have you tried moving the bluetooth dongle to the front USB port?

i Have a single DIN (AVX33), the bluetooth is built-in so there is no dongle.
I read quite a bit about this problem .. it is related to the phone hands free profile sending signals to the headunit in a way that the headunit cannot handle without disturbing audio. It is exasberhated by low signal strength (both bluetooth signal and GSM signal), and also by the fact some andriods will give equal transmit priority to these hands-free signals that it does streaming audio. This is why turning wifi off helps a little (reduces interference). The signals that are interfering with streaming audio are the ones about battery life, and GSM signal strength. As signal strength chagnes, the phone sends out a new value despite the headunit not needing to do anything with it. This is what interupts the audio consistently but irregularly
End result .. it can be fixed by software adjustment on the andriod (do not send updates when streaming audio .. unlikely with Atrix unless Moto gets their thumbs out of their asses), by software adjustment on the receiver (unlikely as JVC is a **** company that does not care about my woes), or by mitigating the problem as I appear to be forced to do. I do this by turning off the "phone" porition of the bluetooth. Or by starting the music and THEN connecting to bluetooth. Unacceptable to me but I have no other options.
I f**king hate how complex our electronics have become and how consumers are powerless to fix these problems DESPITE the fact some of them have a higher level understanding of what the problem actually is. (therefoer I will not be purchasing anything from JVC or Motorola ever again. They prevent me from solving problems and refuse to fix them for me.)

Bluetooth Car Stereo

Finally got bluetooth in my car stereo and reviewed some threads prior to posting, but not sure anyone asked / answered the question I have. I'm basically wondering how people are using their bluetooth stereo's. From what I can tell so far I have 2 options.
1. Phone pairs, i listen to my car stereo and if a phone call comes in the stereo picks up the call if i say, and upon completion back to my car stereo
2. Phone pairs, put the car into BT Audio mode and stream audio from my phone including phone calls.
The problem is, i'm looking for a way to combine both. For example I'd like to be able to listen to my car stereo, and if i get a notification i hear it over the radio, not just phone calls. I haven't tried yet, but i'm guessing the nav will be the same way, if i'm listening to the stereo and running nav on my phone i will get no turn by turn like i would if i was listening to music on my phone and running nav.
Is there a way to do this? Am I missing something? I have the Sony Xplōd™ MEX-BT3900U. Is this a limitation of my stereo, or just not how most people use their bluetooth?
I just ordered a replacement radio as well with BT support. I'd be curious wth what other people have to say with experience as well.
I use this all the time.
Both options will work provided the head unit you bought supports media streaming.
Your phone will connect both phone and media over Bluetooth. You listen to your media and if a call comes in you can take it while the media is paused. Media will resume after call completed.
Notifications and navigation will pause and resume media as needed.

I've found the quality of the audio over bluetooth to be very degraded. Have a rear AUX 1/8th port and run a cable to mount, Then use BT headset for all if need be, but have Pandora playing Excision & Downlink radio the entire time

Multiple Bluetooth Audio Devices

Phone connects to my car via bluetooth for calls only as headunit doesn't do audio.
I want to add a bluetooth receiver to the car for audio (belkin bluetooth caraudio connect) while still be able to use my headunit for calls.
Is this possible? Or will the phone only allow one audio device at a time?
I would only be using one audio device at a time, but they would both need to be constantly connected
Did you double check that audio is enabled for your car bluetooth? In the N4's settings.
And after trying, I can't get 2 BT devices to connect at the same time.
I have 2 bluetooth devices currently connected to my N4, jabra wave headset for phone audio and jambox for media audio, works perfectly. Just have to go into the bluetooth profiles for each and disable the audio you don't want (ie phone audio for headunit, and media audio for belkin) Not 100% sure it will work with your devices, but certainly can be done with some.

Hey,
Perfect exactly what I want to hear before making the purchase

[Q] Play music thru BT while Headphones plugged

Scenario I'd like to see:
Wired Headphones plugged in
Bluetooth connected to audio receiver
Music plays through audio receiver
Calls go through wired headphones
If a call comes in it pauses the music app and transfers audio to headset. As soon as call complete music continues.
I can get this to work on my Scotts Clean Rom Note 2 and iPhone 5 fine but I can't seem to find a setting or app that can allow this behavior.
Why?
I much prefer hearing music through my car speakers and if I get a call it's much easier to hear and talk through the wired headset.
Anyone else have this use case? Figured out an answer?
Just a thought since I haven't tired this yet.... What happens when you turn off phone audio(but leave media) for the car in the bluetooth settings on the phone?

Gave it a try, still reverted to headphones.
Thanks though!
