Stereo BlueTooth Headset Quality/BitRate

I've just bought the fab iTech BlueBAND set of bluetooth headphones, and have got them working with my JAM with the new BT stack plugin.
The quality is a bit dodgy though...
I know the popup message says it's streaming at 192Kb/s, but while most of my songs are encoded at 160Kb/s (which sounds relatively great on wired headphones), the higher frequencies in particular have a lot of static-like distortion through the headset. It's not unlistenable, but not really that good either. It is digital after all! So I'd expect it to either play perfectly or cut out completely.
Does anyone know if there are any reg settings to fix this? Or does anyone else use the same or other headsets and experience distortion?
Please let me know,
Cheers,
Joe

Your issue is not limited to the phone, it appears to be an input clipping issue with the BT A2DP input. It's touchy.
Right now, I'm listening to 192kbps mp3s out of my computer with a Macsense BT-100 (Class 2, v1.2, USB2.0) running the BlueSoleil 1.6 BT stack, and a pair of the new Moto HT820s, and I get that "crunchy" high end like you're describing (or at least what I think you're describing). The only way I've found to correct this, is to lower the actual input to the BT. Not sure how you can go about that with your setup offhand, but with Windows it's just tweaking the Wave volume down a little bit.
Hope this info has been of some usage to you or anyone else having this issue. Oh and I was having the issue with the HT820s and a co-worker's Bluetake BT009x (Another Class 2, v1.2, USB2.0). Again, resolution was turning down the Wave on them, and I was all set to go.
Just a fun off-topic sidenote: The HT820s with a BT adapter running the BlueSoleil stack, allows control of winamp's next track, previous track, pause, and play functions using the right earpeice's multifunction and skip buttons.
EDIT: Wave @ 50% and the crunchy sound is gone except where expected with clipping from far far too much audio being mashed together.

Thanks for your idea, looks like we need to just find a way to lower the output volume from the streaming software to the headset.
Does anyone know if this is possible through a regedit or anything?
I'm also looking for a program that will toggle the 'stream audio to bluetooth headset' in the stack extension. Then I could create a shortcut to it for wisbar desktop like with the CicleBT program.
I'm aware that viJay has made software that does this for WM5 but not for the magician's cambridge A2DP extension.
Hope that made sense!

Send me over a copy of the software/stack and I'll try to look into it, if you've got it at hand.

Good news...
I switched BT adapters, I got my ISSC adapter in the mail today and have been putzing around with it at work and at home, and found this out. It works great, has great distance (I got 30m out of it with a wall between myself and it, and it's only marked for 10, while the CSR adapter that I had before was marked at 20, and couldn't even go that far without breaking up to almost nothing in line of sight.), and isn't crunchy with the high-end on the audio! Maybe you can check your XDA and see what chipset it uses, and possibly opt for an ISSC based one instead of CSR-based? Better yet, i'm going to start a new thread asking people to post up the chipsets in their XDAs and other BT devices so I can compile a list of chipsets and how well they work with certain data-intensive protocols such as A2DP and File Transfer.
More info: CSR stands for Cambride Silicon Radio, and ISSC stands for Integrated System Solution Corp.

That's interesting!
I've managed to get about 15m distance with line of sight between my Jam and iTech headset, but only about 8m with walls and floor between them.
I suppose this tells us that it's either the chipset itself or the coding of the stack that is affecting the quality/volume and causing the clipping.
As I use Wisbar Desktop I didn't like permanently having the notification icon displayed so i renamed the btAVPgui (cant remember exact name of the exe) in the windows directory to get rid of that popup interface. Now I just turn the streaming on and off in bluetooth settings. Hopefully vijay will find a way to create a shortcut for that!

I'll be looking at it ASAP - still updating old stuff though, but I'm working on some very funky new stuff too, and Mrs Vijay555 is limiting me to 30 mins a night (programming, not other stuff!)
V

Cool, thanks.
I have some programming knowledge so if there's any pointers you could give me to figure it out myself, please pm me!
Those cold walks to college every morning are much more fun if I don't have to take my gloves off to get my music playing!

joehood:
What does the screen look like? You said there's a bubble in the bar at the top?
Frankly, the easiest way to tap it would be to use a Mort script. I have one set up to control the volume - just emulate a click on the top bar, eg (180,5) will approximately hit the volume icon (from memory only!). Set this up with a shortcut, and to quote futurama, "Pow".
Forgive the old screenshot, I'm at work:

Icon in claunch near bottom left will click the volume icon and permit use of the dpad to control the volume. No screen taps required.
Could you do the same for your bluetooth?
Either way, a programatic solution would be nicest, but hard work, no doubt. But I'll try to investigate.
V

OK I have the exe that creates that popup notification with the button to enable or disable A2DP streaming depending on its current status. Is there any way I can find out how it's changing the status? I've looked for a registry setting but couldn't find anything. Where else would the setting be stored?

I am amazing I am amazing...............etc
Woohoo!
I've done it!
It was a regkey after all. Found it by looking through the .unload file that CSR create in the windows dir.
HKLM\Drivers\BuiltIn\WaveDev
Then 'streamOn' is obviously activating streaming
'automute' self-explanitory
and I'm guessing showConnStatus controls the status notification.
Now... is there an easy way to create a programe which toggles the registry value? Please let me know how to programme changing DWORD values.

joehood: these things aren't usualy just a registry entry, but certainly could be.
I think mortscript can change registry entries. Try that first, and if it does or doesn't work, we can consider writing an app to do the switching if necessary.
V

I just got home and wasn't thinking when i wrote the first post, now to edit it and make myself look a lot smarter.
On windows, there is default support for .REG files that integrate into the registry and make changes on the fly based on the contents of the file.
Example:
Filename: ShowConn.reg
Code:
[HKEY_LOCAL_MACHINE\Drivers\BuiltIn\WaveDev]
streamOn=DWORD:00000001
automute=DWORD:00000001
showConnStatus=DWORD:00000001
When this is run, it should set streamOn to on, automute on, and show connection status to on. Make another like this with the name HideConn.reg and change showConnStatus=DWORD:00000001 to DWORD:00000000 and that should turn it off. Just run whichever one, keep them in a folder and keep a shortcut, have fun switchin.

Of course! haha
I did write a little mortscript file for it last night anyway, this one toggles it on or off, but doesn't change the show connection status or automute values. Personally I hide the notifications icon in wisbar because it was permanently there before. I'm using btp_audio_ui again to confirm that files are streaming, but currently have no way of telling the status of A2DP without trying to make a sound.
I didn't bother putting the automute function in because I leave it on permanently, no need to have both sound sources really.
I'm getting VS2005 so I can have a play, will try to design a bluetooth manager program which has large fancy buttons for turning on/off the most useful functions.
The more we can get these things performing like real phones the better!
Next step: to find out how to play WMV audio through A2DP!

joehood: are the registry changes dynamic? Ie, when you incorporate your defined registry settings, the streaming/mute etc happens immediately?
V

yep!

Cool. I guess I can build them into VJVolubilis as well if you want.
If you've got a bunch of them together, PM them over.

Can anyone send me a bt stack with stereo support, recived my plantronics 590a today. Thanks

Oy...
Get BlueSoleil, make a new thread or search the forums next time though. I'm almost ready with my thread I hope to get Stickied with info on the software and chipsets for bluetooth.

So what you are sayin is that BlueSoleil works with WM5 to get stereo or what?

Skype 3.0 Beta for Windows Mobile

Download
Here is the introduction for the new version:

"lightbox_next": "Next",

Skype 3.0 beta for Windows Mobile integrates two big features from the desktop version--file transferring and SMS. Both are welcome additions that bring the mobile VoIP application much closer in line with the newly updated desktop version, Skype 4.0 for Windows.
The SMS feature has been seamlessly added as a shortcut icon on the contact list page (it's the black circle encasing a tiny cell phone), but you can also initiate a text message by selecting "Send SMS" from the Menu options--the cost will come out of your Skype Credit. The file transfer feature is a bit more buried. To use it, select "Contact Options" from the Menu choices, and then "Send File." This will incur a data charge, so it's best to have a data plan in place before going wild with transfers.
As soon as you ship your image, song, or document out to your buddy, a new tab opens in Skype for Windows Mobile 3.0 beta that keeps track of the transfer and lets you know when your contact has accepted the download. File transfers work both ways, of course, so you'll be able to accept files sent through Skype while you're on the go--crazy photos and important business documents included. File transfer worked without a hitch over our 3G network, as did SMS. Wi-Fi will make them even faster.
After SMS and file transferring, the next biggest change is a technical one that most people shouldn't notice--the fact that you won't have to decide between downloading the version for Windows Smartphones or for Pocket PCs. A single one-size-fits-all download makes installation blissfully brainless. In addition, the beta has undergone a few understated, but useful changes to its layout, like being able to update your status, add hyperlinks to chat messages you may have missed, and the option to buy more Skype Credit.

I installed a older version of skype on my xperia. But, I cant get the voice input working on my headset. I must use my phone's mic to talk.
Is there someting i can change to use my mic on my headset instead of my phone?
Thankx

wont be long till they release the x1 panel version. (a panel is out in beta but does not seem to work at mo). i heard some panels are coming out tomorrow

Can anybody help me with my problem about the mic input on the standard headset. I cant seem to use the mic. on the headset with skype.

download the attachment and extract audioswitch.exe to your device\Program Files\new folder(any name you like)
copy audioswitch.exe and paste a shortcut at window/startup
Now you can forget your headset...

Thanks, but thats only for the audio output right? I need to know how I can use the mic input. Tried it with audioswitch but that only regulates the audio output.

If we install new beta Skype so do we need to install Skype panel?

Does it work when you make a normal phone call ? does the button works to hang up or activate voice command ?
Me and many others have the problem that X1 recognizes Headset as just earphones (whit no mic), a workaround is to plug it in while a call is placed , then it will work fine , until you unplug it or soft reset. you could test it and write back here ..
Call any one and while speaking connect the headset, now hang up and make a skype call

Shwan_3...
I haven't tried it. Last monday I returned my X1 becouse I had nothing but problems with my phone.
They sayd that the copper plate in my headphone slot was damaged and my phone kept saying that there was a headphone jack in the phone. So when i wanted to call someone i had to une my headphone :S. I hope I get my X1 back in a couple of days (they sayd 2 weeks).
It's to bad, becouse the x1 is a sweet phone! Now I'm back to my Samsung G600

Crap!
Just got my x1 back! I had to wait like 6 weeks! SonyEricsson has a terrible service center here in Holland. They had to wait for 4 weeks untill the parts came in. And the sad part is, its still busted. Cant make a deacent phone call.
Pff....

when skype will have videocalls?

Skype cab file
can anyone share skype PPC (cab file) skype.com no more have windows mobile downloads.

Skype 3 is on this forum:

can anyone post a download link for a working version of skype for x1?
i installed one before but it didnt work, once i run it, screen just went black and freezed...

[APP] Google Car Home 2.2.1.4

I've got the Car Home app working for Galaxy S2. As you can see, it is not available into Market for our phone.
Download the Car Home app and make sure you install first com.android.cardock-8-2.2.apk file.
For those of you with rooted phones, flash the Google signed package from CWM recovery. This is the package I currently have installed on my phone.
The app features the Voice Search integration, allowing you to perform various tasks like calling a contact directly with a command similar to "call Alex mobile" or "listen to Michael Jackson". It also has a cool automatic mode (Day/Night) and links with your bluetooth car system.

Tip: If you are rooted, uninstall VoiceToGo and VLingo apps, they are useless once you use Voice Search app.

Can anyone confirm if the Car Home starts automatically once you place the phone into Samsung Vehicle Dock kit? It should from what Google says... I'm going to get the dock, is damn sweet.

Confirmed. Use it every day!

Awesome! Can you tell me the feature you like most while driving? Can't wait to test it with a mount.
I updated the screenshots to show the shortcut created by apk...
I like that it starts the Google Music app, if you click on Music shortcut.

Here is a flashable zip. Flash in cwm. Will install apps to system folder.

Thanks for the new files. I really hate that I cannot get the app from the Market, so we get proper updates... Probably Samsung did not wanted the app because they went the VLingo way ("Hi Galaxy") and Google banned the app for all related models.
How I got the app working on my phone:
I Googled forever until I found a compatible cardock launcher file with 2.2.1.4, which for some reason everyone had it named CarHomeLauncher.apk instead of com.android.cardock-8-2.2.apk. Then, I exported both apps with the proper name and version assigned to each file.
Edit: I just found a Google signed package and link it to the first post. I flash it and everything works great.

awesome, thanks

Superb, loving it...
only question -
do you know if it is possible to add a direct dial for a contact?
I can add a contact, but when I press on that added contact I get the contact's options (message/call/email etc...)

Personally I use Voice Search option in Car Home. If I want to call Alex, I just say "Alex" and it will pop the contact. If anyone has other tricks, please share them.
Edit: Whoaa, I just tried the Voice Search feature: "call Alex mobile", it worked!
Works well with specific songs I want to listen to. I said "listen to Thriller":
This is a great app... I'm playing with the other Voice Search options as we speak.

Thanks!
Installed and working perfectly on Epic 4G Touch (SGX2). Thank very much!
So lame that they block us from installing it from the Market. I wonder if it's because of the car-centric crapware that gets bundled on our phone...

Yuck nasty suction mount.
Look up a Brodit Active cradle for the GS2. use inconjunction with the specific pro-clip designed for your car.
You'll never look at another brand of car mount again.

I own a Nokia CK-300 car kit, it connects through the car speakers, mute's them on phone call, connects through bluetooth and streams music through a2dp perfectly. Has a small microphone usually placed close to the driver's head. Also has a small remote control, useless with this phone (voice commands!!)
Will this app work with this car kit? I wonder if Google Car Home will accept commands through BT connection......

I don't think Google Car Home is what you think it is. All it is is essentially just a launcher with big icons which are easy to see while driving. It also allows auto-launching when it detects connection to any bluetooth device.
Any voice-activated programs are a totally separate thing.

I mean, will Google Car Home accept voice commands passing through BT connection?

Google Car Home has nothing to do with voice commands!
If you are talking about Google Voice Search, then no, I haven't found a way to get this to work through a bluetooth microphone. Would be cool, though. In any case, this is off topic and is probably discussed elsewhere.

Erisin ES2046B (4.4.4) installed and set up. Question regarding sound amplification

Hi all,
I've just installed and got everything up and running on this unit in my E46 and had a question regarding the audio quality when playing music.
I use GoneMad music player as it's got one feature I haven't found in another music app, standard star ratings support embedded in the music tags (all my music is rated), and as such have set up smart playlists that only play songs rated 4 stars, 5 stars etc. This way I can carry and sync my entire local library between phone, car and PC.
Now, I've toyed with the GoneMad EQ settings and can't seem to get the sound to be as crisp as I used to have on the Parrot Asteroid Smart I used to have before.
I installed PowerAmp just to see how much of a difference that makes to the sound quality, and indeed after tweaking the PowerAmp EQ settings, the bass is much richer and treble is clearer.
I have already set the Android headunit's "Amplifier" preset to bass and treble boost by the way.
I have enabled root on the unit, and essentially all I want is to be able to use GoneMad, but with the audio quality of PowerAmp. In the past on my Android phone's I'd installed Viper4Android sound and that's improved the phone sound output to headphones, but Viper4 doesn't seem to install the audio driver on this headunit once the app is loaded.
Can anyone advise on what I can do to improve the sound quality of the headunit without resorting to soldering the IC bypass? I know the sound can be improved via software, since PowerAmp does something the other are not doing, so can this whatever that is, be done via a root app?
Thanks!

No matter, fixed it, installed Viper4Android FX, updated Busybox and tweaked the Viper EQ and clarity modes to suit. Night and day difference. thie cheap Chinese head unit is now excellent everywhere.

If you can afford it, worth spending a little more and going for the ES4046 model. It uses newer hardware (MTCD instead of MTCB in the above), runs on Android 5.1 and supports DAB+ (if you spend an additional 50 dollars on the DAB module). I have the above which is good for modding but development focus is moving to the later model so probably a little more future proof.

I've got another Erisin (ES3015V) and I'm pretty unhappy with the sound quality as well. Installed Viper4Android, which makes it better, but I'm still not happy. It can't compete with my original low end stereo (RCD310/Skoda Swing). Could you share what you did with the clarity modes specifically? Thanks!

Peugeot 407 rockchip PX3

Hi,
I've installed a new android headunit today. Running android 7.1 out of the box.
I have a few problems with it and a few thing I'd like to know how you do it.
Problems:
- Not all buttons work like they should. Temperature adjusting works fine but changing the air outlet on the passengers side doesn't.
- The car settings app is doesn't work. The toggles go from on to off and back...
Question:
- I'd like to use bluetooth tethering for internet, but that doesn't seem to work. the bluetooth settings look different and I can't choose to use the internet connection. Usb tethering would be a great alternative but I don't thing its available.
The only other option would be to use the wifi hotspot but I hate the fact that I need to switch it on and off all the time.
Hopefully you have a solution for these problems.
Thanks, Frans

I've just installed an Erisin head unit with Android 7.1 in my VW Passat.

My solution for tethering was to use the wifi hotspot on my Nexus 5X. I've used Automate to enable/disable the hotspot when my phone connects/disconnects to Bluetooth so I don't have to switch it on and off all the time.
Overall I'm pretty happy with it. Everything works as it should. I've replaced the default launcher with Car Launcher Pro which seems to be the only car launcher specifically designed for use on an Android head unit rather than a phone. I think it looks a lot better than the default one.
I've installed Waze and Spotify which are now linked together so I can switch between the two really easily. I'm using TuneIn for the radio, but my mobile signal sometimes drops out so I'm tempted to buy the additional DAB unit.
The only real issue I'm having is some slight buzzing interference when the engine is running. It's not terrible but I'll be looking into how I can earth the head unit better to try and suppress it.

Hi,
Do you have found a solution for this problems?
I'm thinking buy an Android head unit for my Peugeot 407, but I'm afraid that many options doesn't work, without original screen...

Hi guys,
I've changed the oem Head-Unit of my Peugeot 407 with a new PX3 with Android 7.1 and all main functions of the original system are ok.
Original Head-Unit was a WipNav (RNeg) with a 7" color display.
Now with the new Head-Unit set I can controll the dual zone clima (all controlls, pilot and passenger) and consumption indicator.
Some pictures at below...
What's your problem for the controls or buttons?

Hi trudtilp
Thanks for the photos.
I appreciate if you can answer a few questions:
- The unit, show external temperature, as the original screen show?
- Are the car messages displayed? Like "Low exterior temperature", "Front left seatbelt open", "Doors open", "right headlamp failure", "esp malfunction", ...?
- Original parking sensors are working? Beep and graphics or only beep?
Thanks in advance!

Hello everyone, I'm very interested in this because I would also like to install a head unit: the latest version androïd 8 on my Citroën C5 (RC_) (of course the screen should be adapted ...)
I ask myself some questions also about the sensors of recoil because the car has 8!
I know there are interfaces (look for "DanyMecano" on Youtube) but no way to know if this interface can accept as many sensors
And finally, my car is equipped with amplified JBL sound ... I saw that there were JBL CanBus decoders for Toyota (Aliexpress) but again, nothing for Peugeot 407 (or C5 with the same configuration)...
I'm French so I use the Google translation and I apologize if you do not understand everything!

As I know, JBL sound on Peugeot 407, works great with any canbus, also with the old versions that do not support reverse parking sensors. In a Spanish forum, there are an user who confirm that.

Ok I'll watch this thank you very much
#EDIT:
Do you have a link please?
I just watched 10 pages in Spanish language and I did not find anything ...

Hello everyone!
I found some information ... In ".es" as Peixeiro said!
A sale (too expensive) but the first info is very clear! :
"With this equipment, functions are not lost.
The steering wheel controls, vehicle information, parking sensors, climate, even the JBL system are retained.
With Android 7.1"
I also found a Chinese seller (Seicane) who gives an interesting info in his description, it say:
"Please note: this unit only can support your original car's reversing radar if your car's origin CD is a small screen less than 4.3 inch, then this unit can't support your car's reversing radar."
Below there is a photo of the RD4...
