Let's add A2DP to the 700w/wx

benjimatt · 10/20/2006, 12:41 PM

ok i really want the a2dp application. I am over at xda forums a lot and i am trying to get into this programing thing. but what i was wondering is how many of you have already tried to use a2dp. and with what files and what was the problems

benjimatt · 10/20/2006, 01:08 PM

so far this is what everyone is doing. but i think i have a plan

Now you can use A2DP (Bluetooth Stereo) on HTC Tornado w/ AKU2 ROM...

1. The ROM should be updated as latest AKU2 ROM from i-mate (SP5 or 8310: i-mate_SP5_???_2.5.33?.?.zip, SP5m or 8300: i-mate_SP5m_???_2.6.33?.?.zip) and unlocked by RegEditSTG.exe and SDA_ApplicationUnlock.exe .

2. Copy Avrcp_MPplugin.dll, bta2dp.dll, sbc.dll to \Windows thru ActiveSync.

3. Copy Tor_A2DP_cert.CAB to any folder (I recommend \My Documents), and execute CAB from File Manager.

4. Import or modify A2DP-related registry values, using MobileRegistryEditor (see Readme.txt or A2DP.reg included in the ZIP file).

5. Power Off and On

6. You can enable A2DP for your stereo headset, from Settings - 6. Connections - 2. Bluetooth - Menu (right softkey) - 1. Devices - Select your A2DP headset - Menu (right softkey) - Set as Wireless Stereo !!

my plan is to replace these registry dlls with the ones from the 750v roms.

[HKEY_LOCAL_MACHINE\Drivers\BuiltIn\BtA2dpSnd]
"Flags"=dword:00010002
"Index"=dword:00000008
"Order"=dword:00000008
"Prefix"="WAV"
"Dll"="bta2dp.dll"

[HKEY_CLASSES_ROOT\CLSID\{7AAC2B28-5DD1-4052-81DD-E17114EE96B6}\InProcServer32]
"ThreadingModel"="Free"
@="Avrcp_MPplugin.dll"

these are two of the dlls that are used. i havent looked at the contents of the cab yet. ill do that when i get home.

but i cant find sbc.dll the treo 750v doesnt use that file. so i am looking for the alternative file

akijikan · 10/20/2006, 01:21 PM

I thought the shortcoming was in the hardware?

benjimatt · 10/20/2006, 01:28 PM

no no no. i dont think it is. the 750v has it and it is using a 300mhz samsung processor

benjimatt · 10/20/2006, 01:44 PM

im probably going to change these setting too

ill probably have to add this whole key

[HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\Bluetooth\A2DP]

[HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\Bluetooth\A2DP\Settings]

hey hannip the a2dp reg that you posted in the xda forums looks pretty good. it adds a few more keys than the reg from the tornada a2dp

here is the one from the tornado

on thing i am not understanding though is that in the reg. file for the tornado app it doesnt mention a sbc.dll so what is this file for then?????????

akijikan · 10/20/2006, 07:05 PM

I wouldn't think it has to do with the processor, but the bluetooth hardware...I could be way off though

smeg36 · 10/20/2006, 07:12 PM

I doubt it is strictly a problem with the hardware. If it were, the tornado A2DP hack wouldn't run on the 700w at all. As it is, it does run but stutters while doing so. That leads me to believe that it's a problem with the software not being optimized for the Treo. Obviously there are many devices with the same speed, or indeed slower, processors that can do A2DP. I think it's just some software incompatibility with the Treo that needs to be worked out.

I would like to agree. The 700w is driven by Bluetooth 1.1. What is the 750v? And the tornado also?

oh okay...I wasn't aware that there was a half-working hack already...I do some reading before I open my mouth next time

codyppc · 10/20/2006, 07:35 PM

good luck. not trying to high jack your thread ,but will this do the bluetooth dialing?

this is what i want and i know the 750 does it. someone told me that the bluetooth stack was tied to the radio so it may not happen.

benjimatt · 10/20/2006, 08:20 PM

cody im not really sure about that. i foucus on features that i care about. lol. jk

benjimatt · 10/20/2006, 11:38 PM

ok some problems have arose. i guess its not going to be that easy.

right now on my 700w i can play about 15- 30 seconds without a skip. its pretty cool. but the skip is still there unfortunately.

um i tried replacing the dlls and i had to get them signed.

bta2dp.dll this is the dll that directs the audio toward the headphones(it has the menu for the stero headset option)

i tried to replace this file and it did wont show the stero bluetooth option.

but i was able to replace Avrcp_MPplugin.dll . im not really sure if it did anything though.

bthutil.dll is already a dll in the 700w but i dont know how to replace it. the windows directory wont allow me (codyppc i think this is where the feature you want is)

all the dlls have different sizes.

bta2dp.dll 51.4kb (tornado) vs 33.5kb (750v)
Avrcp_MPplugin.dll 10.9kb (tornado) vs 7.00kb (750v)
bthutil.dll ???? (700w) vs 23.0kb (750v)

it seems that the tornado files have much more than we need. but im going to attemp to read these dlls now

mjnoles1 · 10/21/2006, 02:15 AM

Like "codyppc" asked...... please oh please get bluetooth dialing working on the 700wx, I will do anything for that and I do mean anything lol j/k...but seriously I really really would love to have bluetooth dialing working on the 700wx

hannip · 10/22/2006, 12:44 PM

Here is a cab that installs the 750 bt a2dp files. I could only get it to work on the 700w however. I can't get the dll's to load on the 700wx. Haven't figured out why yet. The bad news is that I am getting the same lag issues as with the tornado dll's.

You are welcome to try it out. I haven't messed with priorities yet.
