A2DP

[patrickkoch]

Ok so this is not the only phone that I can see that is wireless everything but does not support A2DP so you can listen to the mp3 player wirelessly??? I have seen that some have updated other units (MDAIII) to use a BT stack from broadcom and I was wondering if it is possible to do it on the sp5? I am guessing that using the broadcom stack does not require BT 1.2 but I am not sure what stack the sp5 is using and where I would get the updates. I am also reading that most that have done an update have mention static if they move around?? Why then would you need BT if you cannot move?? Is this then the V1.1 causing the problem and why it should be on 1.2?? :?

Ok so I have asked the question about the sp5 & sp5m about A2DP so you can use stereo bluetooth headphones that include player controls and I found some answers.
A2DP only fully works on Bluetooth V1.2 and these units only V1.1. I have seen that some people have installed some third party BT stacks on there BT V1.1 units to get high quality stereo profiles but they do not have player control. Also it may not even be A2DP it may just be a facsimile but more interesting it may be A2DP. When looking at the specs of phones it says Bluetooth V1.1 but does not say which silicon (Chip) is in the unit which is very important because the chips are backwards compatible. Meaning it may be V1.1 but the chip maybe able to run V1.2 because the manufacture just put in V1.1 stack and rom. So we should all be not asking about new stacks and upgrades but first ask which chip is in the units and if it is a V1.2 compatible, then we should start demanding rom and stack upgrades now. As for the chips the V1.2 and more chips have been out for at least 2 years so the manufactures cannot say the release of them postdated their own development date unless they have been hand building the units for the last year and that gave them one year to test.

Well can someone please tell me which or who’s BT chip is in the sp5 and sp5m

You will also find that Microsoft have not written support for this yet into the OS

Funny about the support because for what i know HP ipaq work just fine on A2DP along with other MS units so sombody must be supporting the headphones because there are sure alot of them coming out in the next few months.

[saldous]

HP probably wrote their own drivers.

I combed through the TI website, and all the BT chipsets that are used with the OMAP 850 chip(in the Tornado devices, like imate SP5M, etc) are showing BT 1.2 as their spec. I don't know why it's not included, but I know that MS has promised to but out a A2DP update in Spring 2006, so maybe we will see a ROM update from i-Mate/HTC, etc at some point. I know that it is possible, or someone could build/hack their own stack. It least we know it is possible, hardware wise.

The chipset (included in omap850) is:

I2S/AC97 Enhanced Audio Controller (for Voice) and a UART (serial) for data.

I'm afraid that a 200MHz CPU will not be fast enough to support A2DP.

I'm using A2DP on my XDAII, it REALLY slow down the entire system. That's one with 400MHz CPU! not to mention a 200MHz.

where'd you get a2dp for xda2? been searching the site and the internet for this...

My XDA II is using 1.62c.07CHS of WM5, which seems to have A2DP built in, even not necessary to install any BT Addon.

You can find more information here: http://www.buzzdev.net/

interesting...i've upgraded my xda2 to wm2005 as well...just have to check if this is the same rom. thanks for the info

[wsabido168]

ok, do you know where I can get the 1.62c rom in ENGLISH? :)

some news on qtek rom with a2dp and push email. looks like it may come in feb. if anybody has qtek membership could they check for details.
thanks

I have a T-mobile MDA using the Qtek Test Rom and i use the plantronics Pulsar headset audio quality sounds better than an ipod. I can hear deep bass. I think it is just stupid that HTC hasn't been putting A2DP on the AKU 2.0 update stating it slows the phone way down, etc. I use A2DP while at the gym so, i am not needing to write an email while using it. Well I guess to each there own.

I've got the Qtek Wizard test rom and use it to listen to music on my martian-looking Pulsar 590s, and it slows the bam thing to a crawl. Can't really do anything at the same time.

Bummer really, cos it's not that slow a CPU, just damn sh1t-slow software...

Well... I believe there is some kind of data compression mechanism in A2DP protocal. The problem is, maybe some devices have hardware (chip) to do the compression, and some devices let CPU do the job. And I think our Tornado would leave this nasty job to CPU, so it can slow down the phone a lot: COME ON! It's realtime data compression! This job is not suitable for a 200MHz CPU! It's cruelty to CPU.... :twisted:
