General :: Bluetooth 3.0 Multicast Audio Android 4.3?
Oct 29, 2013
I've just bought a great Bluetooth Speaker to use with my Nexus 4 and it works great. Because it was fairly cheap I went and got another in the hopes that I could connect both speakers to my N4 and output audio simultaneously to both speakers at the same time. I quickly discovered this isn't currently "working" or even possible.
After a lot of Googling, I found an app on the Play store that supposedly let me connect both at the same time but it doesn't output audio to both speakers (I get "static" from the second one). There are also conflicting opinions about whether this is even possible with the current Bluetooth spec although it does mention multicast support and all I could find are various workarounds that involved using a secondary bluetooth transmitter etc.
Any software/hack (root needed or otherwise) that would allow configuring audio to be streamed/output to two connected bluetooth speakers simultaneously? Others have suggested it for use with bluetooth headsets.

getting one Android device to be able to stream its audio to another Android device. Specifically I want to stream music but I'd also like notification sounds and other audio to stream.
I have a second, older phone, that I am repurposing.

I've got a conundrum that I can't seem to work out from Googling. I suppose I will give the background then my question.
I use my xperia z2 tablet at the gym to watch TV shows because the treadmill is even more uninteresting than the landscape around my place. I don't like to be hooked up to it via headphones because I don't want to accidentally pull it over. So - I use a bluetooth audio receiver I plug my headphones into, and they receive the audio from the tablet (which is paired with the receiver).
I would prefer to just use my phone in place of the receiver, because the receiver is cheap and doesn't work so well (and i cant believe it can't be done).
I thought two options could be:
1 using the phone as a bluetooth receiver, or
2 somehow using the wifi hotspot on the phone to enable the audio from the tablet to play through the phone.
Does something already exist or is it even possible?

Today we can make calls connecting through Bluetooth on car, and have the sound on car's loudspeakers.
Is it possible to send music, or a podcast, the same way?

I have a samsung galaxy s2 on AT&T running android 4.0.4. I have the bluetooth set up to play audio through my car stereo.
Everything was working fine until a couple of days ago when I accidentally booted my phone into safe mode. I re-booted it back into normal mode, but a lot of my settings got messed up after that happened.
The odd thing is that now, when I am in my car, the phone connects to the stereo over bluetooth - I see the name of the song, artist, etc information on the car stereo, and can do things like skip to the next song using the controls in the car. However, the sound actually plays through the phone speaker instead of the car speakers!

I just got a 2010 Infiniti G37. It has a USB port, but no aux input and no Bluetooth audio streaming (wtf Infiniti?). It reads and plays iPods and iPhones just fine. I can not get it to recognize my android phone at all (Motorola triumph running stock 2.2 rooted). It will recognize flash drives though. I think the problem with the phone is it takes a few seconds to click 'connect USB storage' and then 'ok' before it reports itself as a mass storage device. By that time the car is already reporting an error. I have tried with debugging on and off.. is there any tweak, app, or hack I can do to force my phone into USB mode (without the prompts) every time I connect it?
This is actually a pretty important feature to me and I'm disappointed I can't get my phone and new car to play nice. Might even consider switching to an iPhone if there is no other option.

Is there a way to control which application send audio to Bluetooth and which sent to system speaker?
I have a Bluetooth car kit that is paired with my Samsung Galaxy SII phone (ICS 4.0.3) and any audio that is played on the phone (messages, phone calls, media, etc) it's sent to the car kit.
This is very annoying, because if I listen to the car radio and the phone receive a message, the sound is sent to the car kit, resulting in a interruption of around 10 seconds, only for transmitting the ring of the message.
I want to have only the phone calls and the media player audio passed to the car kit through the Bluetooth and to block any other audio notifications (and to let them play through the phone speaker).
Is there is any way to control what is sent to Bluetooth, or what application can send audio to the Bluetooth?

I use a BT A2DP headset with route planners Sygic and Navigon running on a HTC Flyer tablet with Android HC. With every spoken instruction the first 2~3 seconds are lost because of some delay when audio is started. I know for sure that this delay is not in the headset.

found an app that will allow me to send audio to a bluetooth receiver / speaker AND allow me to use headphones / wired speaker at the same time??
I'm not rooted. If this could be done via rooting, I might just consider doing it.
AND, while I'm asking, can the audio signal be sent to and received by two different bluetooth receivers at the same time? I currently only have one bluetooth audio receiver, so I can't try it.

I'm trying to receive data from a multicast address, but the call to MulticastSocket.receive() blocks until a timeout takes place.I did some network sniffing and found out that my device (and the emulator) never send a MulticastSocket.joinGroup request.I tried running the same Java code from my PC as a standalone application and it worked well. Could it be that the Android platform blocks IGMP join requests?Has anyone succeeded with Multicast on Android before?My manifest file contains the following permission:I am running my application on 2.1 (Both emulator & device).Any ideas anyone?

i am developing an app that will control a multi-room audio system. I have implimented the following, which works fine on my own network at home (cable modem and D-Link DIR 855 router), but does not work on the office DSL Motorola modem/router. Our iPhone app and our Pronto ProntoScript app work at both locations, so I know that the multicasts are being sent properly. Any ideas?

Has anyone else starting experience issues with bluetooth audio since the 2.2 firmware update? I have never had any issues with the bluetooth audio connection with Microsoft Sync in my car but since the update I can't get through a track without drops all over the place. I am forced to connect via the audio cable; then everything is fine. Like I said, I very occasional hiccup before the update; now it is all the time.

I met a problem of bluetooth headset. I want to switch audio playing to bluetooth headset when bluetooth headset is paired. I found BluetoothDevice in android sources which can control bluetooth. However it is not contained in android.jar. So I used AudioManager.setBluetoothScoOn(true)
But it still can't work.

how can I route audio to bluetooth ear when a bluetooth ear piece is paired? I have set my audio manager to be MODE_IN_CALL. audioManager.setMode(AudioManager.MODE_IN_CALL); I am not sure if that apply to my case, since it refers to some deprecated methods. Plus, doesn't android detects if there bluetooth ear piece is paired and routed to ear piece on phone or bluetooth ear piece automatically?

I want to stream audio directly from my mac via bluetooth to my nexus one. This might sound crazy, but I actually want to be able to control the audio from my mac. I just want to be able to connect an audio jack to my nexus one and let it stream the audio via bluetooth. Is there an app for that?

if it was possible to route audio files from the phone to a bluetooth headset on versions of Android API Level 7 and under (so versions older than the new Froyo) If so, do you know of any sample code I could look at to figure out how to do this? Or perhaps just point me in the right direction?

Considering writing a wifi cracking (wep, wpa) auditing tool for the android platform, but I am wondering if it is possible to do without a rooted phone.
I had thought it would be impossible to run on an unrooted phone due to the phones wifi chip ignoring packets not addressed to the phone. That is, without the ability to set the wifi chip to monitor mode many of these attacks wont work. I was surprised to learn that android supports multicast packets. That is, android phones can be set to receive packets not addressed to them.
My questions are: Does having a multicast lock mean I can receive all packets broadcast, or does it only apply to packets with a multicast flag (if such a thing exists)?
Is there a difference between monitor mode and multicast? Does the android api have a system for switching channels?
More generally I'm curious: Is anyone familar with other wifi cracking projects running on android (google searches turned up very little)?
What difficulties am I likely to run into?
This question is related to SO question Is there anyway to put Android WIFI (droid handset) into permiscuous monitoring mode?

Am trying to play music on HTC Magic via bluetooth over the car stereo. I am able to control the phone's music player via the car stereo but no sound. Call control works fine over the car stereo via bluetooth. I have tried my wife's Nokia and it plays music with sound via the bluetooth over the car stereo. I have checked and HTC Magic does show the bluetooth is connected with phone and music.

I can't seem to get my Desire to stream audio on my Parrot MK600 car hands free kit. It pairs and connects, I can make calls over the hands free and it downloads the contact but when I play music from the stock Music app it still comes out over the handset.
