[Q] Samsung Galaxy S5 MIMO Allocation with Bluetooth and Wifi - Android Q&A, Help & Troubleshooting

Hi Everyone!
I'm thinking of purchasing a Samsung Galaxy S5, but I have a question about its Broadcom BCM4354 MIMO 5G WiFi 802.11ac / Bluetooth 4.0 / FM Radio Module. An image of it can be found at this link, which I can't seem to post because I am a new user (i58.tinypic.com/9icnfb.png).
As you can see, there are two WLAN antennas (marked #3 and #4), but only one with the capability to run both BT / WiFi. I'm wondering -- does the existence of two antennas enable developers to simultaneously receive / send bluetooth packets while receiving / sending wifi packets? I found this SO post (stackoverflow.com/questions/15927208/iphone-programmatically-use-wifi-and-bluetooth-at-the-same-time) which describes a coexistence protocol implemented in most phones that prevent them from truly use wifi / bluetooth simultaneously without any coexistence limiting.
So my question is: On the Galaxy s5, which has two antenna (both with the capability to use WIFI, but only one with the capability to use Bluetooth), if i were to programmatically send data via bluetooth and then programmatically send data via wifi, would the phone auto-allocate to use both antennae? or would it simply use a coexistence sort of deal using one antenna? If the latter, is there anyway (through root / development) that I can enable the phone two use both antenna?
Sorry if this question is ill worded, let me know if you want me to clarify anything!
Thanks

[REQUEST][DEV] Remote Sim Access Profile (rSAP) - bluetooth

Hi all,
We all know that rSAP is not supported by Android
Those with carkits (VW, Audi, etc) with this profile cannot use their Android phone. A massive disappointment.
What will it take to get someone write some code to get this bluetooth profile to work on - for starters - the basic Froyo code for Nexus?
I'd be happy to kick off a project with a $150 donation or an HTC Hero (such as for testing).
Assuming we can get more people together who are interested in this (I am positive!), the big question remains - who would be able to write the required code?

We need rSAP

In Android issue 4402 (not permitted to post outside links, just go to the google code page and search for 4402) about the rSap profile some people are reporting that the Samsung Galaxy S (I9000) does have the rSap profile and does successfully connect to VW/Audi premium carkits.
In the Galaxy S forums are some roms (including a MCR rom for the Galaxy S) ... so there might be some possibility to port some code from the Galaxy S to the Nexus One

Thanks, I found it and repeated my post there as well.
I really hope that someone can come up with something. Surely, as you say it works on the Galaxy S, one must be able to get this to work on the Nexus One, or any other Android phone for that matter.
Hoping to see some more replies here! Or maybe a recommendation of a programmer who might be able to do this.
Cheers, MC
Hi, I have the RSAP working on an Samsung galaxy i9000 wich my Audi built in car phone. The only hing bugging is the sync of phonebok. It synces alright, but with phone conacts only. It took me a while to realize that phone conacts and my primarily used exchange contact list are two different things in this setting. First I had believed it synces only sim contacts. While this is not the problem, I have not found a way yet to "replicate" the synced exchange contacts or map them to the phone phonebok from business contacts, wich would make them visible to the carphone via rSAP.
maybe someone here knows a solution or an app that would solve this? The rSAP itself works, as Samsung has implemented it into the Galaxy i9000.

I will exceed the OP's donation and donate $151 who ever manages to crack the rSAP on Android. Samsing just made the sourcecode (search: Samsung releases Captivate source code) so there seems to also be a ZIP file for the GT-I9000 (European Samsung Galaxy S).
I am stuck with TouchHD for my VW PremiumGSM, and would love to get an Android.
Cheers and keep it up devs!!

plz, an app for rsap on n1!
Android on GSM... maybe, but limited; CDMA not likely
According to a post 4402, "rSAP allows different devices to connect to your mobile's SIM Card to read your contacts etc. The car than uses its own antenna and gsm Module to call. The mobile phone goes in a stand by mode which needs very low energy."
If this is true, then your rSAP-bluetooth connection is actually hijacking your sim card ID and using it to place calls and receive calls through the car's integrated GSM radio, and not actually synching as it seems. In this case (in the US), there is no Verizon or Sprint fix because neither network uses SIM card (chip based ID profiles) technology, and furthermore, both their networks are CDMA and therefore incompatible with Bentley, VW and Audi GSM modules. If the connection could be bridged, the car's GSM radio would be seeking access to a network the CDMA user is not subscribed to.
So the definitive end is that as long as you have a VAG auto, you better have an rSAP GSM phone to use with it.
Ironically, Apple iPhones are GSM and they have had a longstanding good relationship with VAG, so I am surprised to find them boxed out of compatibility with Audi and VW especially. I am not certain, but it could have something to do with Apple's unique provisioning architecture is as much as they do not have a readily accessible SIM card (or battery), and in doing so, they are not respecting the need for SIM portability.
When I worked at a multi-carrier mobile phone reseller years ago, I briefly had a SIM-card based phone that I could then take the SIM card from and insert it into any GSM phone (from the same carrier) and use that phone to place and receive calls. This same migration can be effected in CDMA technology, but only through over-the-air provisioning, and that process is not as immediate as the rSAP SIM takeover process seems to be.
I'll keep looking into this matter, but perhaps the upgrade we should be barking for is to have VAG integrate support for the same bluetooth profile (HFP) that BMW does. BMWs from 2007 on with bluetooth will connect to my Droid X all day. rSAP just overtakes your SIM id and uses it to place and receive calls on the car's GSM radio. Of course it also can access a portion of your Address Book, but after that, you are stuck with the features offered in your car's radio and no longer have full utility of your Droid phone features and apps, etc. As a result, Google Voice search will be a non-starter for Android rSAP unless the car's GSM radio is actually running Android OS as well. And how likely is that...
maybe this could help?

Rsap works..but no Bluetooth audio
Hi,
I got my I9000 working on my Premium Bluetooth in my VW Passat. However I cannot figure out how to get the Bluetooth Audio (in the Media Secion of the car display) working. I have enabled it in settings in the car. AUX works, SD-card works.. but bluetooth audio I just cannot figure out.
Does any1 know?
I have a NTG1 Comand in my Mercedes, and the rSAP conection works like charme, with the SGS(2.2.1 jpy).
Only thing that not works is the PBAP so only my sim card contacs r listed!

Hi, Bluetooth Audio works exactly as it works with bluetooth headset: you need to launch a music player on the phone and then the audio will be transfered to your car's speakers. I just got my new VW Touran and SGS works almost fine with it (having troubles with the contacts with emails, which are not synced to the car). I think I'm going to get an SDHC card for my music (Media-IN works great with a usb drive).

Any ICS rom supporting Bluetooth MAP (Message Access Profile)?

Are there any ICS roms that have support for bluetooth message access profile? It's for accessing sms via external equipment like car decks.
Thanks
Functionalities depend on module, not ROM.
So does that mean GSII does not and will not have MAP capability?
I'm pretty sure GSII is capable of doing MAP ..it's just missing the software. It uses the same Broadcom BCM4330 chip which is also found in the Nexus ..and that according to Google, supports Message Access Profile http://support.google.com/nexus/bin/answer.py?hl=en&answer=2687662
MAP sounds like it could be incorporated into another Rom.
How can we do this?
Can the bluetooth software from the Galaxy be pulled from the phone?
Who knows how to do this?

[Q] data connection and its influence on voice connection

Hello,
Is anybody aware of the fact that radio connection (mobile, wifi, bluetooth, gps etc) can influence voice quality connection? Does anybody knows if evidence exists?
If yes it is a good idea to automatically disconnect all active radio connection during the call eg by mean of a tasker.
I just can't find any evidence it is true (eg. Developer of Sanity has got such a functionality in his software)

[Q] Multipoint bluetooth enabled phones

Hi Everyone,
Just to ask this question regarding Bluetooth functions on phones mostly on android. Has anyone knows an android phone which has a functional multi-point Bluetooth capability?
As i know only headsets can do multi-point to connect multiple phones at the same time, but not i heard of on phones.
This has been brought into asking since i was unable to connect on both bluetooth (blueant q1) headset and my live-view. It's only connecting on one device and then the other one will be disconnected.
----------
Knowing that this could use more power if this feature has been created, but can be made to be disabled as part of power saving settings.
I hope someone from the dev team can take a look at this functionality as this can be a great feature if enabled on android phones.
This could also mean modifying the bluetooth stack for this to enabled, but it seems to be a worthy one to be tried.
Thanks!
Hmmm.... seems no one is interested =(

Bluetooth 4.0 switch

Hi,
this might be a silly question but is there a way to activate bluetooth 4.0 in Android 4.3 and leave "classic" bluetooth switched off? The reason I'm asking is that I'd like to use power-saving BT4.0 to detect Texas Instruments SensorTags within reach and perform several automation tasks, including activation of "classic" (i.e. power-hungry) bluetooth to connect to a handsfree set.
On my Xperia Z1 I don't see a way to activate the two protocols independently.
Cheers,
Torsten
