Maybe someone has had some luck because I am so frustrated. Since updating my 8320 to .180 I am no longer able to use Bluetooth haedsets while on UMA. With my original software I could use my headset on UMA but would have occasional dropped calls.

To maxamize the free calls with UMA I purchased a Bluetooth phone from At&t so I could answer my cell from any of my home phones. It worked great when I was not on UMA but on UMA I cannot even check my voicemail.

I think it is ridiculous to have to loose my bluetooth feature because of UMA. I realize that they share frequencies but come on. I want to be able to use bluetooth in my home office and get free calls. Who wants to hold a phone to their head for 6000 minutes a month?

I have tried multiple headsets with no luck. What i want bluetooth the most for while at home is the At&t bluetooth phone so if I recive a call I can answer my cell from any phone in the house. It works great with edge but no luck with UMA. There is a serious problem with the the incapatability of bluetooth and UMA. I know I can use speaker phone and a wired set but it is broken if I cannot use a feature of the phone while on UMA.

UMA is a great feature that I bought into but it shouldn't cripple bluetooth. UMA is supposed to replace a home phone but I find myself running downstairs at a breakneck pace to make to my office for a call. I love my phone but I am not holstering to my underwear at night so I won't miss calls. That is where the bluetooth phone from at&t comes in. You pair it to the base and you can have 12 headsets spread out through the house. You can make and receive calls through your cell phone. The problem is I wanted to get free calls through UMA to cut down from my minutes.

I am having the same problem with a Jawbone, Jabra X10, and 2 different Plantronics headsets. I went to .180 and the phone rebooted a few times while on a call with one of my bluetooth headsets that I had to go back to .171. Now I am getting dropped calls most of the time I am trying to use UMA and a bluetooth headset. I have done as sgtcasey suggested and now am having to use the wired one that came with the Curve. That AT&T phone dentalrep was talking about sounds really cool. Maybe after Tmo sorts this bluetooth issue out I will go out and find it and give it a try.

I hate to say it, but this is not an absolute problem with the OS. I have .180 and use a Jabra JX10 everyday with ZERO problems. It has much more to do with channel ID or outside interference on your WAP and/or Router perhaps.

I'm on a Linksys WAP without a problem, and it's not a TMO router either. I'm sorry for anyone having trouble, but it isn't really accurate to say the problem lies with the .180 upgrade.

I also have had this issue since going to .180, I would suggest going to .175 to see if you're able to achieve UMA stability while retaining bluetooth use. I am currently at .180 and will roll back to .175 this evening to see if that helps with the issues.

I have a Linksys WRT-300N at home running dd-WRT using WAP2 and WMM. When I use my stereo headset on UMA, it always drops immediately or it never even makes the call to begin with. When paired to my Jabra BT800 it works fine with UMA.

I used to be able to use the headset for about 20 minutes without a problem on .175.

After a long conversation with T-Mobile I finally got my case #(4338143) for the bluetooth issues with UMA. They spoke with RIM and RIM needed to speak with me. The RIM employee stated that it is a known issue that they are aggressively addressing. It is NOT hardware or frequency related but rather a software problem. He also aknowledged that the .180 software worsened the problem. If it was hardware or frequency, then software wouldn't make a difference.

He also stated that if anyone else had similiar issues that they should call in. The more people that call in the higher it goes on their proirity list.

I did a test today with my free time. I downgraded to .171 and I could actually check my voicemail with a bluetooth headset while on UMA. It was not perfect, and I did drop a few calls but I did have a 20 minute conversation without a drop.

I then upgraded back to .180 and did a clean install. Connected to UMA and then paired my headset. I tried to call my voicemail and did not hear one word and got a call failed. I tried about 10 different times even after a battery pull, with no luck.

As a reminder, whne I am not on UMA I can talk for 8 hours on any of my bluetooth devices.

Did you try .175 at all?

Does this test hold true with a regular BT headset (not the ATT handset you've mentioned)? This is definitely interesting that you get such a different experience across OSs.

I tested it out with a jabra JX10, Nokia bh800, and my Garmin 2820 while in my garage.

I tried .175 and I had the same problem as .180.

Glad to see that they are aware of and addressing the issues, but I have to disagree with your statement that if it was hardware or frequency related that software wouldn't make a difference. Just ask anyone that has perfomed an upgrade to WM5 or WM6 and see hown the same exact hardware reacts more stable and the environment of the device has better response and signal. Yes the hardware won't change, but the filtering or algorithm to arrive at the signal handling and handoffs could be improved or degraded therefor directly affecting how the hardware reacts (so yes software could affect how things are handled in the device). I had a I730 that came with Windows 2003se and the BT was unuseable on it (some said i was the hardware implementation on the device), but when Samsung released the WM5 upgrade the BT worked flawlessly afterward (it was a case of the software implementation not correctly being handled and this causing the hardware to e unusable, so it can happen both ways).

Really interesting... I use a JX10 and it works fine on UMA with both .175 and .180. I'm sorry that your experiencing this problem. What router or WAP are you using?

I am using a Moto HS850 headset with UMA and it works great. Some have said that changing the channel on your router will fix the problem. I havent had to change anything and have my router set to channel 11

I am having this exact problem, i have tried every channel in my router and no luck.

No matter what i do i can not make or receive calls while using a bluetooth headset and UMA. I am using a T-Mobile CURVE with 4.2.2.180 and a Motorola H680 headset.

Jeff

There is a newer OS - 4.2.2.184. Not sure if it had any affect on bluetooth, but you may want to consider trying it out. My phone does fine with a Motorola H700 and UMA. I'm using .184, but I think it was ok on .180.

I have the same trouble with 184 as I did with 180 and my bluetooth devices.

Just wanted to get this going again. I had a water incident with the curve I had and now have one that has the words "WIFI" on top which means it is different from the one I sent back. I have .184 on this unit and now I am able to use my Jawbone and UMA. Now I have also a new T-Mobile router for "Talk Forever" that has made a huge difference in my UMA usage.

There has to be some variance from one BB to the next. My daughter and I each have 8320's on Tmo on the same family plan. We each have Tmo Linksys routers. Our 8320s are both on 180 OS. She has a jawbone that works perfectly for her making UMA calls at her place and at mine. If I try to use her Jawbone on my 8320 I get booted to EDGE immediately at both locations. I've gone through both 8320s and the settings are nearly identical.

The only difference that I am aware of is that her 8320 is a few months newer than mine (based only on date of purchase).

I am using my Bluetooth headset with UMA with the beta 4.5 software on the Curve.

what headset is it that your using?

Jeff

Nokia Bh800. By the way, I could not use it at all until I installed the beta 4.5 software.

T-Mobile Curve 8320
Scala 700 headset
Linksys WRT54G-TM

I had the same problem as others have posted here. I could not use my bluetooth headset with UMA calling. Call failed, disconnects, et. al.

I discovered this by accident. To improve the range of the Wi-Fi I set the Router to band G-Only. I left the 8320 as dual b/g band. Wa-La No more problems.

I am not a techie and will leave the technical debate and explanation to the wizards. All I know is that I can use my bluetooth headset with UMA now.

Only complaint I have had is that callers on the other end have said that I sound quieter while using the headset with UMA versus EDGE and to turn up the volume when using UMA.

I am using blackberry hand held version .180 and linksys firmware version v5.00.38, Nov. 30, 2007 if that helps.

Hope this Helps

I had the same issue with one of my bluetooth devices. Whenever I tried to make a call, I would get the 'call failed' message.

I turned off 'Encryption' for the device, and I'm now able to make calls.

how did you do that? can you explain its steps please..?

options > bluetooth > scroll to device in question > menu > properties > ecryption > OFF

I'm having the exact same issues. I posted here where someone redirected me to this thread.

I've been going around and around with T-mobile about issues with UMA, but Friday I realized that the bluetooth being connected was the source of the problems. I verified this on my network (WRT54G-TM), a T-Mobile store hot spot, and at work (WRT54G). All places it worked fine with no headset connected and cannot make or receive calls with the headset connected.

I tried turning encryption off as suggested above but it did not help.

I only have one week left on my 30 day trial period of service with T-Mobile so I need to decide if this is going to be a deal breaker or not. My biggest need for UMA is at work where the T-Mobile GSM signal is too weak to penetrate the building. AT&T's signal comes in fine, however since AT&T stopped paying T-Mobile to use their tower, service at my apartment went so far downhill I can't use them any longer. T-Mobile's signal is much stronger, however in the back of my bedroom I often drop service.

I forgot to ask, what is the update from everyone? Has anyone found a bluetooth headset that works reliably? I currently have the Motorola H12 but I think I'm going to take it back because of volume and comfort issues.

Apparently it depends on model of your BT. It works with some and no with others

I can confirm that the Motorola H700 works while the Motorola H12 did not. The only problem is that the H700 is a piece of crap For $44 I'll see if I can use it while we resolve these issues. Thanks for the tip.

Note that the above was tested on .180 (the latest official T-Mobile version)

i have the same issues with my 8320 i just bought new from t-mo last week. call fail and reverts to edge with my jabra bt8040 headset. tried every conceivable setting and it still results in the same behaviour. sw version 4.2.2.180.

gonna go to my local t-mo store and see if they'll let me test other headsets to find one that works, start a case number, and contact RIM.

other than that, i love the phone. the bt headset works fine for A2DP listening and on edge... just UMA calls fail with it. it wont even connect a call.


has anyone had any luck with the Plantronics/Blackberry Discovery 655?

My Motorola H500 and SE PVH 700 are both are their last legs. And my H375 won't work with BB8820 and UMA.

What BT headsets are you using successfully with UMA and BB 8820?

I'm using an S9 and a Samsung WEP500. Both work with UMA. In early beta versions of 4.5 and OS 4.2, they didn't work.

Just to let everyone know, I have a Jawbone 2 with the same exact problem.

Version 4.5 fixed it.

I can't post links yet but Google "Orange UK" or "4.5" and you should be able to find it easily (I got it form pinstack.com)

Who would I call to add my name to the list??

I can make and receive calls, but they drop after about 10 minutes of perfect voice quality.

T-Mobile Blackberry Curve 8320
w/Plantronics Voyager 510 Bluetooth Headset

The problem continues unabated on my 8900 using OS .199 and a Motorola H15. Exact same issues as above. Two years, no cure?

I upgraded from a 8320 to a 8900 hoping this would improve, but no luck. Any suggestions?

I'm able to use wum and bluetooth at the same time. I haven't had issues with that in quite some time.

I think these problems are either router settings related or bluetooth related. The wifi and headset are using similar frequencies so they if they are both broadcasting at the same time the signals can interfere which each other.

Things to try are checking for a router OS update, and if possible going to an alternative like dd-wrt. dd-wrt has a specific setting to reduce bluetooth and wifi conflicts;.
