Bluetooth issue

Yesteray I bought a Motorola H500 to try to find a solution for the headset problems. As I told you before, I didn't have a headset myself.

I understand now why some people don't have the "Standard Audio" check box on "Bluetooth settings" => "Services" => "Hands-Free" => "Advanced": If you change the value "AudioHandling"=dword:00000013 to other value (as I have indicated in other posts), this option won't be available.

-If you chose this value: "AudioHandling"=dword:00000008, you cannot pair the device. WM5 won't see your headset.

-If you chose this value: "AudioHandling"=dword:00000001, you can pair the device, but "Standard Audio" checkbox is not available.

My Moto H500 doesn't work to make or receive calls. It only works as hands-free if I have checked the box "Standard Audio" ("AudioHandling"=dword:00000013, which is default ROM value) but I cannot use the headset button to make a call (which is pretty annoying, I agree). Right now, I try to investigate what is the problem. I wonder if it's not a radio problem. This weekend I will try to make some tests changing the radio version to 1.13. I have some suspictions about the radio version 1.15. In fact, I haven't seen any manufacturer using this version on shipped upgrades. I've noticed also that some people don't have problems using their BT headsets. My Moto H500 is a 1.2 bluetooth device and reading throw the posts, it seems that people who manage to make their headset working are 1.1 bluetooth devices. This is another reason that makes me suspect the radio version. Finally, before posting this, I was trying to find information on xda-developers about Radio version 1.15 and my suspictions now are even stronger. I found this thread: http://xdaforums.com/viewtopic.php?t=38058&postdays=0&postorder=asc&highlight=radio+1+15&start=75

Subject: Bluetooth Manager NOT responding

--------------------------------------------------------------------------------

Hi all, I recently upgraded my radio stack to the latest version 1.15...everything worked fine until I tried my bluetooth headset and that's when I discovered that something was wrong with my bluetooth. The icon on the lower right taskbar lets me "turn bluetooth on/off" but that's pretty much what it allows me to do. If I go on the start/settings/connections tab and choose the bluetooth icon, that doesn't respond...all other connection icons seem to work....wireless is working fine. sms too as well as phone calling...I don't know what I did wrong in the install...I'm sure I did everything right...can anyone point me in the right direction? Is there a patch I need to download for the bluetooth to work again? I would really hate to "downgrade" my radio stack....and go thru the process of reinstalling all my apps and what-nots....sigh...somebody pls help?

There're also few other posts reporting problems with Radio 1.15

I have decided to go back to WM2K3 for a while and test BT with different radio versions. I will export all BT registry settings (WM2K3 use Widcomm BT stack) settings to compare them with mine.

Concerning to car hands-free problem, it works for me because once I had checked "Standard Audio" box. BT works fine with other hands-free device playing the sound on them (though, I repeat, you cannot use the device -headset- to make or receive call if you don't use the buttons on your BA)

I will let you know what I find out. On your side, you can try to downgrade to Radio 1.13 and check if that solves the BT problem with your headsets. For those who have downloaded my version before 27/04/2006, I recommend to redownload them again. Intead of making a lot of diferents versions, I replace the existing files on the ftp server with the patched versions (file names and links are the same). The reason of doing this is just only for not using a lot of storage room in the xda-developers ftp server.
