Just upgraded to A TC--problem and a couple questions..

[miked112007]

I just got a brand new crusie and I love this thing. I had a Tilt, then the origianl 3450 Touch and now the crusie.

I've got it all set up and it seems to be working great on my AT&T network. modded someof my setting with cabs/ htc customiser.

The only problem that is KILLING me is the bluetooth performance is HORRIBLE. Both with my Motorola stereo S9 headset and my Jabra XJ10. The stereo moto set break in and out if I move a little or put the phone in my pocket. If it's right next to me not moving it's ok. If i run with it in my pocket, NO chance!
The regular jabra works ok with the TC right next to me as well, but if I walk even 15 feet away it just breaks up.
Both of these worked GREAT on my touch?
I remember when I had my Tilt there was a reg edit and an option in the Kaiser tweak for bluetooth performance. Has anyone had any problems with BT performance?? Any way I can Fix this????

Also, I'm either in E, G or H. Att here in chicago has a huge 3G network that supports HSPDA. I assume E is edge. Is G 3G or GPRS?? When my TC is in H is that the 3G or HSPDA? I don't see a 3G symbol?

I really an very impressed with the crusie, but REALLY need to figure out the BT issue as I use my jabra and moto S9 EVERYDAY...
Any help would be highly appreciated!!

You have installed the bluetooth hot fixes from htc.com?

[miked112007]

I installed both the BT hot fix cabs.. The problems in the hot fixes (when the device goes into sleep mode) etc is not what I am experiencing but I tried them anyhow.
If I remember in the kaiser tweak there was some setting for bluetooth band width for performance?? Can we use the kaiser tweak with the TC? I assume not.
Is there a value in the reg that can be editing for this???
thanks again

FYI -- I have the same issue with my S9's. They worked great with my Touch, my Shadow, and my Dash but they work awful with the Touch Cruise. You pretty much have to hold the device up, near your head, to get a constant connection. My Plantronic 855's work fine though. Given that it's S9-specific, I don't think you'll find a registry tweak to fix it, though I could be wrong. If I had to guess, I'd say it's something that needs fixing with the S9's, not the Cruise -- wish they'd made them firmware upgradeable :(

I am using an O2 XDA Orbit 2 which is the UK O2 networks variant of the Polaris/Touch Cruise. I experienced the exact same problem with choppy stereo bluetooth sound on a pair of Sony Ericsson HBH-DS970 headphones (which performed perfectly with my original HTC Touch). I performed the following registry tweaks and this seemed to improve performance significantly:

HKLM\Software\Microsoft\Bluetooth\A2DP\Settings :
Name: UseJointStereo
Value (DWORD): 1

Delete these two key/values
HKLM\Software\Microsoft\Bluetooth\A2DP\Settings:
- BitPool
- MaxSupportedBitPool

[miked112007]

I will give that a shot and I'll let you know.. What is the bit pool and the max??

[miked112007]

Ok---
Under my settings, the use jointstereo DWORD value is already 1? what was yours?
should I still delete maxsupported and bitpool completely? any idea of what those do??

[benjimen]

You want to turn joint stereo off, and that would be changing the number from a 1 to a 0. That won't help with distance, but it will improve the sound quality considerably. It's pretty much the same with any WinMo device -- for some reason joint stereo is turned on as a default. I returned a lot of stereo bluetooth headphones before I found this setting. I thought they were all crap, turned out to be the setting. If you Google 'bluetooth' 'joint stereo' you'll find info on how the setting degrades sound quality.

It's a shame this is turned on by default, the average user will never be poking around in their registries and wouldn't have a clue as to why stereo bluetooth on their WinMo device sounds so bad.

I've not changed the other settings the post mentioned though, if you do let us know how it worked out. Personally, I've switched to wired earbuds -- the best sound quality of all ;)

UseJointStereo is set to 1 (this was the default setting); I don't actually know what the other two key/value pairs function is. I did some google research on choppy bluetooth stereo sound a while back after purchasing my XDA Orbit 2 and experiencing the terrible bluetooth performance. Apparently, the effect of making the changes I suggested is to improve the overall quality of the audio and reduce the 'choppiness' (intermittent signal connection/disconnections).

Both BitPool and MaxSupportedBitPool should be deleted (i.e. both key name and value) for the full effect of this tweak.

For more information on these registry keys just google BitPool, MaxSupportedBitPool, usejointstereo and polaris (all in the same search query).

I use sony bluetooth dr-bt21g stereo headphone. Installed hotfix and done reg tweaks. If i put my phone in my pocket it breaks up really bad. If i have my phone next me; amazing sound.

i think moral of the story, if ur on a plane or in the house then bluetooth headphones are good. If ur out washing the car, jogging or even walking they are crap so i have to revert back to wired ones:D

But I'm searching high and low to see if there is a fix for this. I cant believe that the Athena had very decent bluetooth connection. No problems at all. But switching over to Polars, I have to consider giving up my bluetooth headset. That aint good.

Is it an hardware problem? Is it possible the device is to small? I dont know:(

I hope they fix this!!!!

[timmymarsh]

i dont know! it is bloody annoying when i paid over 50£ for my headphones. I tested in on my imate jamin (now with a2dp:D) and its the same so i dont think its the cruise. I just think bluetooth has not evolved enough yet, just a thought tho and i will test, wonder if the wifi conection interferes with bluetooth signal?:confused:

[Kenjari]

OOOOOHH..:eek: Good insight timmymarsh. I havent even test thoroughly the wifi.

Good thinking buddy, I'm going to try that...turning off wifi and turning on and see if there is any difference!!!

BTW...thats good to know that it might not be the TC. I read somewhere on the Polaris thread that the bluetooth setting on this phone were suppose to be set up for newer bluetooth earpieces.....I dont know how true that is!!!!

[dysolve]

I have never had an issue with bluetooth or wifi on my TC But I never have both on at once, If I am using bluetooth, wifi is turned off and vice versa. In the past I have had really big issues using lets say ericcson phones with moto headsets but if I upgraded the headset to the latest firmware they worked fine. I really do think that the issue is the headset and not the phone.

[timmymarsh]

mm i really should learn not to post after drinking wine:D hence removed:D

[benjimen]

t.m.i. --and-- ew

Bizzare test....

I havent tested properly turning wifi off when bluetooth headset on yet, but yesterday i was washing my car in trousers that had no pockets, so i stuck my phone down my pants against my ass (ha ha). Reception was brilliant when i was moving around; previously when i had put my device in my trouser pocket the reception was terrible. I guess my body was acting as an ariel extending or improving the bluetooth signal hence the good reception.

Extreme i know, but at least you next have a valid excuse when someone says "is that something in your pocket or are you just pleased to see me......." :D

[timmymarsh]

I did eventually test the bluetooth signal and quality with both wifi on and off and both my polaris and prophet.

With wifi on the signal was terrible when deivce was in my pocket, with wifi switched off the signal was good. The signal only started breaking up when with wifi was swtiched on and searching for an access point.

I now only use a2dp with wifi switched off. Im a happy bunny. btw my prophet never signal never broke once when jigging around the room, my polaris did a lil bit even with the wifi off, but there was a marked difference!! :)

[benjimen]

Glad that worked out for you. For me, WiFi had no effect at all, on or off, the signal with S9's are just as bad and the Plantronic 855's just as good.
