[Q] Bluetooth 3.0 Multicast Audio Android 4.3 Possible?

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.

So can anyone tell me if there is 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. It seems if someone could hack/crack this it would be very useful to a lot of people. Maybe even a good idea for someone with the knowledge for a paid-for app. Any ideas? Would really appreciate some feedback on this - even if it's not actually possible - some technical explanation would be great.

Thanks!

Any luck?

Just wondering if you found any solution for this? I also wants to use multiple bluetooth speakers simultaneously with Android phone...

I would definitely pay for this ability

I'm not sure if it's possible with bluetooth, but if someone could make it happen I would definitely be willing to part with some money for that app/ability.

I'm going to try combining two devices from amazon and see if I can send bluetooth audio from my phone to 2 separate (and different models) TDK bluetooth speakers. I will let you know what I discover once they arrive.

First Device:
Monoprice 109722 Bluetooth Transmitter and Splitter http://amzn.com/B00AJHAYCS
According to the description and reviews this device can transmit a bluetooth signal to 2 devices simultaneously. Amazon says this takes 2-4 weeks to ship, so it will be a little before I get to test this out. If it does work it's still a pain because I'll have this hanging from the bottom of my phone. That's why I'm also going to try combining this device with another bluetooth device.

Second Device:
Mpow® Portable Bluetooth 3.0 Audio Music Streaming Receiver http://amzn.com/B008AGQMQC
My plan is to try pairing this with my phone, and then plugging the Monoprice Splitter into the output on this receiver. I'm expecting some loss of sound quality with all these connections, but as long as it isn't too bad the freedom to walk around with my phone might be worth it.

I'm not sure why a single device that merges the capabilities of these two devices into a single body and shared battery hasn't been created. Through all my searching online I feel like such a device would be well received.

no ****. as long as bluetooth has been around, you would think that they would have fixed this by now. what is the use of having a wireless connection that only can connect to one thing at a time. it's beyond moronic, it's submoronic. who wants to listen to one speaker at a time, when throughout history, we have always used at least two speakers, and many times more. you would think even the idiots who make bluetooth speakers, would at least have the ability to hardwire another speaker to the one which is using bluetooth. i have never been more disappointed in a technology than i am with bluetooth.

The reason why bluetooth doesn't support Multicast is because it doesn't have the bandwith to support High Quality streaming simultaneously no would the chips really having the processing power but that could be fixed, but the main limitation is the lack of available bandwith specified in the 802.11 standard for bluetooth.

However future successors to bluetooth will likely have support for Multicast streaming such as 802.15.3a which is being co-developed by Intel, Sony, Philips, Texas Instruments, Samsung. Though the bad news is, it won't be to market for probably another 2-3 years :/

UPDATE: I have received and tested both of these products from amazon. Good news and bad news. Good news, both of these devices work well on their own and do what they are advertised to do. I'm particularly impressed with the Monoprice 109722 Bluetooth Transmitter and Splitter http://amzn.com/B00AJHAYCS. When plugged into the headphone jack of my phone or tablet it sends audio to two different bluetooth speakers simultaneously and the audio is synced very well (not perfect, but for the price it's very good). The bad news, when combined (to create a true wireless system) a decent amount of distortion is introduced which is not heard when using each of these products by themselves. I'm not sure if it's interference from the different bluetooth connections, because the physical connections seem to work fine when used separately. It sounds like you're listening to FM radio where the station isn't quite tuned in right, just some static along with the music. It's not horrible, but it's no where near the quality that you get from a typical bluetooth connection. I might try using another stereo cable between these two devices and see if adding more space between them helps at all. I'm open to any other suggestions. This is close to be a solution for now, but not quite. If you don't mind having the Monoprice dongle hanging from you phone or tablet, the sound quality coming from both speakers is very good.

Hi folks...has there been any progress on this subject?

I am thinking about setting up a whole house, always listening, google now / voice command network using a couple of bluetooth speakerphones and an older android phone. The more speakerphones I can spread around the house the more coverage I would have.
