How do you enable A2DP in the Registry

I am successfully using the Tornado A2DP hack on my Prophet in conjunction with my bluetooth enabled car stereo. I have written a mort script to make the two connect automatically when bluetooth is switched on but there are odd occassions when they disconnect, like if I switch to listen to the radio.
I can't find the registry setting that controls the state of the "set as wireless stereo" function to either 1 for on or 0 for off. Can anybody help?
My intention is for the script to re-connect the wireless stereo if it detects that the registry setting has changed to 0.

I have been busy trying to track down the issues I have been having on my apache with a2dp, try searchnig the registry for "stereo", you should get a few hits.
Otherwise try
HKLM\Software\Microsoft\Bluetooth\Device\[your devices mac address]\services\
There should be a few long strings (folders), most likely corresponding to one for "wireless stereo" and one for "handsfree", in one of those you may see the wireless stereo...
anyway thats what I got with a 3.5aku and moto headset.

shiggs,
I've already tried that path and it does have a "services" folder with Wireless Stereo and Hands Free folder but the Dword value is enabled (set to 1) in both permanently, evenwhen bluetooth is switched off.
If we can figure this out it would be beneficial for everyone with a wireless stereo device for automatic connection.

Surely someone must know what registry changes take effect once "set as wireless stereo" has been tapped?

use a little utility called ssnap to take a snapshot of registry before enabling that option and another snapshot after checking it. Then compare the two file with an hexeditor (for example) and see which key/value was changed/added

Network Video Stream with Coreplayer

Hey there!
I've just read all the "improve video performance" threads, but did not found what i am searching.
I've a big video archive on my home server, shared via file sharing and vista media share. So i am able to access all those (mostly) avi files with my laptops and other Multimedia Hardware (XBOX for example).
Now i would like to open the videos on my brand new xperia, too.
I've got the resco file explorer and mapped the network share, so i got the nice folder list of all the videos.
I've installed the most recent coreplayer, and tried out nearly all setting configurations, but i was not able to get a 20 minutes simpsons episode to play without rebuffering every minute. (And it buffers for 10 seconds, that is just horrible).
I've increased the values for buffering to the universe, or tried to set it to zero.. no improvements.
The option "prefer less buffering over framerate" is just freezing the video while the audio runs on.. great.
So.. what are what are your best settings here? Thanks in advance!

I haven't tried this properly myself, but there's a couple of ideas that I'd try if I were you...
Firstly, copy one or two video files to the phone and see how they run off your phone memory. Avi files aren't supported by hardware decoding, so they won't be running at their best in any case, you *might* want to think about re-encoding files you want to watch to .mp4 h264.
The second thing I can think of is playing with the Start > Settings > Connections > Wireless LAN > Power Mode and setting the slider to it's highest. The battery gets pretty warm on it's fullest setting, but I wonder if this would speed up wireless access for the vids.

Oh yes... i already set this to maximum performance... got no speed improvements from this...
i cannot believe that it is a decoding problem, because if the video stops for buffering, i can tap pause twice and it is running on... but just for 3 seconds. not enough buffering i think.
this post was submitted using the x1. gg
copied avi runs without problems...

the same on my x1...network performance is horrible...video streaming is not possible without buffering.

Same thing here
I noticed the same thing with my X1.
I had hoped it would work better than on my old hp6910 which only had b-Wifi, but it doesn't. Its pretty much the same.

so nobody got an idea here? When i am sitting right next to my access point, there is no buffering... great!

FREE SPB TV for WM

SPB has gone to freeware for their mobile TV software:
http://spb.com/pocketpc-software/tv/download.html?
I tested it and it works fine, but at my current location I have to use low definition.

"Hi"Def (350Kbps) is certainly an improvement over the lower (150?100? kbps), but I find that some channels skip with it. The classic (old B&W mainly) SciFi and Comedy channels (forgotten the names, sorry) for example. Other channels are OK. You often get a few seconds of audio before video appears, and then first second or two of video is jerkier than what follows. Basically don't write off a channel until you've viewed it for at least 10-15 seconds. The skipping stops on lower bandwidth version.
I'm not sure whether the video/audio skipping I mentioned will happen to all people, or whether they have a lot of packets dropping on the way to Kazakhstan. Can't be bothered find stream addresses and trace routing, but something to try another day.
Oh, using WiFi onto a 1Mbit ADSL line btw, no 3G out here, so not able to test Edge quality.

Linking 5 cars via tether for streaming

Wud up doh ladies.
Heres my predicament, my buds and i are driving up to daytona for SBN (spring break nationals, a bass competition) and were basically driving in a caravan.
Each car has at least 5000 rms and up to 15000 rms. (watts)
What we thought would be epic was for me to be djing off of a laptop on the way there, connected via ustream and all 5 cars tuning in to my stream allowing us to play the exact same songs at the exact same time from the 5 vehicles making you be able to hear us from a mile or so away
Predicament. To my knowledge, we have an ipad with ability to tether and nothing else as or right now considering i havent really looked too far into it.
However, We do have a power converter in one of the vehicles allowing us to use a wall outlet essentially.
I was entertaining the idea to have a router connected and to be streaming via a shoutcast server over LAN but im unaware of any app that allows you to tune into shoutcast radios being broadcast over a lan on itouch or ipad or iphone or android for that matter. I am aware that winamp allows you to plug in your listening IP but i have never tested it to work over lan nor on an android and i dont believe its on iphone etc.
So my alternative was to leech internet off the ipad, but if the caravan is 5 cars long, will all cars be able to reach the signal from the ONE ipad, and will that ipad have enough bandwidth to have me dj (upstream, upload) and 5 devices stream (downstream, download). Audio will be streamed at 48kbps if i remember correctly so the bandwidth required ISNT massive however over 5 devices i believe it might be an issue.
if the bandwidth is sufficent i was entertaining the ability to attempt to use the ipad as a WAP (Wireless access point) connected via the router then have an antenna from the router on the roof of the car to boost distance you can pick up the signal from.
WTB ANSWERS, i have 3 weeks to get this to happen

I doubt very seriously the wifi antenna in the iPad is capable of handling this sort of abuse.
You might be able to do it with a laptop and a wireless AP in infrastructure mode and have multiple clients connect to that system.

Sounds like a pretty sweet idea dude! If I were in your shoes, I would create a powerful, rolling, WiFi LAN. Here's how I would do it:
Here's what you would need:
VLC (it's free)
A really powerful wireless router with external antenna's
Make sure the laptop you're going to be performing the broadcast from has its own wired network adapter
What you would do:
Connect your laptop up to the WAN port of the wireless router (the same port that you would normally connect your Cable Modem/DSL/FiOS). This is because you want your laptop to be set up as the default gateway for that LAN.
I would perform the broadcast from the middle car in the caravan for the best signal to the rest of the vehicles, possibly even use external antenna's (like, external to the car itself, not just the router) for the best possible signal quality.
Set up a local VLC streaming server on the laptop. This way you can make the stream much higher bandwidth and higher quality. Everyone can tune into with their own VLC client's, whether on other laptops, or iOS/Android devices with VLC.
Done correctly, this setup won't even require an internet connection, as everything will be done via the local network. That said, if the broadcasting laptop has a mobile connection tethered up to it, then everyone can benefit from that if they wanted to.
Overall, the mobile WLAN idea, in conjunction with a local VLC broadcast, will afford you the best audio quality along with the highest degree of reliability, as you won't need to worry about dead spots in the mobile coverage. Also, this method will yield the lowest latency (because they'd all be on the same local network), so for everyone in the caravan, their stereo's will more likely be playing the same thing at the same time as opposed to everyone playing the same thing, but all at different parts depending on their cellular network conditions.
What do you think?

Will the router do it? Unless it's a real piece of junk, yes. (And by junk I don't mean something selling new for $19.99, I mean something real cheap. Even a $20 router should handle 5 audio streams without waking up.)
Will the idea work? Not the way you want. There will be a delay of up to a few seconds between the streams to each car. All the cars can hear the same song at (within a couple of seconds at most) the same time. But close enough that there's no echo? No.
Connect a computer's web browser to a web audio source (police scanner, or anything else where the source doesn't start by your connecting to it, like a podcast will). Connect your phone to the same source (using its browser). Notice that there's a delay between them.
Nothing you can do about it - that's just how streaming works these days. Maybe for SBN 2025.

With encoding and decoding of digital audio streams, signal quality, et cetera.. you'll find it hard to achieve a truly synchronized stream. With new ATSC broadcast standards, even television sets in my household are off-sync; there is an echo.
Here's where analog synchronization comes in. It might seem very old-fashioned, but you could use an FM transmitter for this. I don't know much about them, but be aware of FCC regulations here in the states. You'll need a fairly high-power one and an omnidirectional antenna. Plan on a nice big investment, too!
Some cons to an FM transmitter:
1. Reliability: it's RARE that you'll find a vacant station in a metro area. Broadcasting over live stations is illegal, and requires a LOT more power than you can get in a portable FM transmitter.
2. Security: the music stream is unprotected. Just about anyone nearby could pick up your station and use YOUR tunes.
3. Vulnerability: it's possible that someone else could bring a more powerful FM transmitter, and broadcast Justin Bieber to your five vehicles (yikes!)

It'd probably be easier to store local copies of the music in each vehicle and use a network connection to handle synchronizing hitting the "Play" buttons.
But you'd probably have to write a whole new application.

Ya, anything that encodes and decodes is very likely to do it at a slightly different rate, so synchronization would be very difficult. Even if you could get them started at the same time, they will probably slip out of sync after some time, too. This goes for the idea of just pushing "play" at the same time. Music playing at slightly different rates may sound the same to us, but will shortly fall out of sync.

On the other hand, to broadcast only a few hundred feet you could probably get something at a computer store that would handle it. I know I picked up a $10 FM transmitter meant for iPods and CD players to connect them to a car stereo. It transmits from my computer to my stereo about 50ft away with no problem, though I haven't tested the limits. It would be easy enough to just plug it into your DJ machine and set all the cars to the same radio station. You could try sticking it to the top of the car and see how far away the other cars still get a clear signal. If it's not enough, you could probably pop it open and extend the antenna a little and get better range.

Where are you driving UP from? Cuba? All of that for a 4 hour trip if you are as far South as Miami?

xpather that
Cool idea

i'd go with analog, i.e. FM transmitter

You ought to have good line of sight on the other members of your caravan.. While I'd recommend keeping the DJ in the center of the pack, even if all five cars were strung along you ought to get good signal from front to back. Just don't get too separated (finding ways to manage that is half the fun of caravaning).
I'll echo what was said above and recommend you preload your songs on all the devices. Streaming synchronized audio is simply impractical. *Playing* all the songs at the same times might be more doable. Maybe. Your mileage may vary, etc etc.

Bluetooth Connection Problems -- Please help

Hello everyone, I bought a new 2015 Jeep Cherokee Trailhawk, it has the 8.4N Uconnect system installed.
I can connect with bluetooth with any other devices, and everything works properly....EXCEPT my phone which is a:
Samsung Galaxy S4
Branded by Fido in Canada
It is rooted, still using the default rom that came with it, but I'm running Nova Settings instead of Touchwiz
SGH-I337M
Android 4.4.2
-----------------------------------------------------------------------------------------------------------------------------------------------
In my car, I goto Phone/Bluetooth settings, have option to change PIN to anything I like but left it at '0000'
On my phone I goto Bluetooth, turn it on, make it visible, hit scan......it finds UCONNECT
I press on it to connect and THEN.......
On the car:
if it is the first time trying since reboot, you can see the passcode show up (six digits - 3 digits a space and then 3 more) and an ACCEPT button. This immediately disappears and it says 'There was a problem connecting with your bluetooth device. Please try again'
If it is not the first attempt after a reboot of phone, it just blinks that first screen showing the weird seperated 6 digit pin and immediatley goes to the error messager.
On the phone:
When it finds UCONNECT and u choose it, a message pops up saying to confirm the passkey and press OK or CANCEL.
It always shows a random 6 digit number.
At the same time, a system message appears for a couple seconds at the bottom of the phone that says 'Incorrect PIN or Passkey. Please try again'
Pressing OK or CANCEL just returns you to the bluetooth scanning screen which shows UCONNECT as an option.
If i try to set the pin on the car with what was shown in the phone, it doesn't work as each attempt to connect generates a random pin on the phone.
I have restarted phone, car etc. Reset car radio completely. Removed all devices remembered on the phones bluetooth. Checked with UConnect support that my phone is compatible -- they say that it might be that Fido in Canada has done something to the phone to prevent it to connect to cars, as it works fine with Verizon/At&T/ and apparently people on Rogers in Canada with S4 works too.
I have commented out the blacklist entries on the phone in /etc/bluetooth/auto_pair_devlist.conf - no change
I have removed all files in /etc/bluetooth - no change
Other phones connect to Uconnect with no problems.
My phone connect to my TV and a bluetooth receiver connected to my home stereo and a second TV different brand no problems.
This is my main phone, also my new car. It really sucks that I cannot get it to pair. Fido, Uconnect support can't help - they have never seen this issue before.
I don't understand why the car shows a pin of six digits with the space between the two groups of 3.
Also, why the phone says incorrect pin or passkey.
PLEASE HELP!! I am going crazy over this!
I really don't want to, but if there is no fix, I will have to backup everything, format the phone, install perhaps a Verizon or something build of Android and then try to connect with that (hoping it has no issues with phone/data use with Fido network over here)

Updated info
I just tested with anothers car....
2009 Nissan Rogue...works fine (is used as an audio device only...no phonebook etc features)
Also tested with an Iphone 5 to my Jeep and that phone connects fine.
I tried using an app called 'Bluetooth Fix Repair' from the app store. It gives an error at startup:
"Sorry this application cannot find your bluetooth setup folder on this device"
Can this be the issue?
The bluetooth folder I was working with in the OP was on the phone at etc/bluetooth
Should I have another one somewhere...maybe missing or corrupted?
Any help!?! Cannot find anyone else with this same issue here (xda) or on google etc.
