I-mate SP5 A2DP

Posted in Gadgets | Windows Mobile at Monday, April 24, 2006 5:19 AM Pacific Daylight Time

Lately I've enjoyed listening to DotNetRocks and HanselMinutes during my commutes to/from the client. I was using the cheap headphones that come with the SP5 which work pretty well in that taking a call while listening to a show is pretty seamless. However, being a gadget guy I thought I would like to upgrade to some better headphones.

Round One - My wife bought me a the HS850 handsfree device from Best Buy. I set it up and start my drive to work. I put the headset on and hit play on the phone. Strangely the audio comes out of the phone's speaker instead of the headset. With a little google research I figure out that I will need stereo headphones to play windows media to the hands-free headphones. The HS850 goes back and I order the HT820 stereo headphones.

Round Two - The new headphones come in and while the hands free part of the headphones work just fine with my SP5, the stereo part does not. A little more google research and I figure out that the phone would need to support A2DP which is part of the AKU2 update. I already have applied that update from i-mate so I put in some support requests and post questions to their support forums: no response. I give i-mate a 1 of 10 for their support on this. As far as I can tell, the A2DP support was pulled from the SP5 AKU2 update, maybe in the next update.

Round Three - Ok fine, my perfect scenario won't work, maybe I can salvage the situation a little by using the headphones with my Toshiba M2 laptop since it has bluetooth. Well I'll skip all the work it took to get a Toshiba bluetooth stack with A2DP, but eventually I found the download (hint: it is the one for the m5 (v4)). Everything seems to be great until I try to connect to the headphones and get the screenshot above. WTF is SCMS-T?!?! Thankfully I was able to google up a solution from here to here to finally here which contains a link to this file. Run the file and it turns off the SCMS-T requirement. Sweeet! Now I'm listening to music and when a call comes in on my phone I can answer it while the music pauses. Fast forward, skip tracks, etc. It all works great, as long as I run that program everytime I reboot my laptop. :(


Why is this so difficult? At this point I'm ready to buy an MP3 player to use as my music source and just deal with having multiple devices. But I can't seem to find a player that supports A2DP over bluetooth. Imate: update your software! Toshiba: WTF is SCMS-T? Motorola: I love the headsets!

Update: [via SmartPhoneThoughts]:

"The guys over at xda-developers.com did it again and found a way to enable A2DP on Windows Mobile AKU 2 updated devices, even if your operator left out the A2DP and AVRC Bluetooth stereo profile out!"

Amazing! Downloading now....

Update2: It works! I can now use my HT820 headphones with my sp5. The interface has a few bugs (like windows media doesn't automatically restart when I'm done with a call), but hey it works. If you're looking to get this working go here and/or here. I had to turn off bluetooth, then power down and back up to get it working on my phone.

Excelent, Cheers, I've been scouring the web for a workaround for SCMS-T for what seems like days now to no avail; shame it doesn't stick upon reboot, but it's better than nothing.

For your information SCMS-T is yet another form of DRM (I'm really getting fed up with the RIAA's paranoid posturing - they'll be jabbing cameras in our eye sockets next) intended to prevent piracy over bluetooth (who the hell uses bluetooth for piracy?!). As far as I can tell SCMS-T achieves this by deliberately degrading sound quality delivered to bluetooth audio devices (WTF headphones are designed for HQ audio!). I've been told that Toshiba are actively reconsidering their current possition on SCMS-T; with luck the next version of the Toshiba bluetooth stack will come with optional SCMS-T (if not I'll be raised seven sorts of hell with 'em!).

Give Windows Media some time, _usually_ mine restarts just fine after a call after a few seconds...
Make sure you pick up and hang up using your left ear button...

Would just like to add i am about to purchase a moto 805 headset for use in my asus w2p laptop i noticed it included the microsoft bt stack which did not support a2dp. the bt unit inbuilt is toshiba so i did a little search and noticed there is version 5.10.01(T) available and that SCMS-T can be disabled so we will see.

If you are using Toshiba Bluetooth Stack, the latest version 5.10.06 *now* has a *check box* for SCMS-T protection. Download version 5.10.06 at http://aps.toshiba-tro.de/bluetooth/

fyi if you're still using the program that you need to load everytime you reboot there is a better option for you.

you need to delete you bluetooth stack software reboot and install the current bluetooth stack on your toshiba laptop and reboot again (toshibas instructions) you can find the current version for your os here:


then under the bluetooth options you now have the option to disable scms-t. i had this problem with my toshiba laptop and now it works just fine.

actually it looks like the person above has already gave this advise but for those that need a little more instruction here you go.

Thank you Benjamin, for posting the link to the driver and stack update, been driving me nuts looking for it. It didn't work out of the box on my toshiba sat a215,
and I guess I must have not followed the directions correctly because removing and reinstalling as directed didn't work. Going to give this set a try.
