Is there a bug in i OS5 RE Bluetooth?

1) What kind of blue tooth?

2) Factory or aftermarket? Stereo or just a purchased in car?

3) Did you remove your iPhone form the vlue tooth device?

4) Have you checked to see if the model of blue tooth is compatable with your iPhone? What iOS on the iPhone? And what iphone model?

I am also having a problem pairing my iPhone 3S with Bluetooth devices since upgrading to iOS 5. My iPhone worked perfectly fine the day before I upgraded. Since upgrading yesterday I have had problems connecting with my BMW X5's built in Bluetooth. I also have a Jabra BT 250v headset. I was not able to initially connect to this device either. I tried turning the the bluetooth off and back on in the iphones, Settings - General - Bluetooth. This seemed to fix the problem connecting to my Jabra headset. It did not fix the problem connecting with my car.

Hi,

I have the same problem but I'm trying to pair my iPhone 3GS and iPad 2.

Both run iOS 5 and both devices are visible/discoverable to other devices NOT running iOS5. But they are not visible to eachother.

Before I updated there was no problem and I used my iPhone as personal hotspot for my iPad, worked like a charm. After the update to iOS 5, the problem began.

I'm sure other people must have experienced the same problems, since I'm not running unique setup.

Regards

I have reported the iPhone 4S Bluetooth connection issues to Apple as a bug. I have also schedule a support call for Thursday, 20 October. I will provide an update if anything substantive is discovered on that call.

The problems most likely are the result of a stack issue in the BT 4.0 (BTLE) code. The new iPhone 4S (which is of course running iOS5 as well) will not connect via BT to either the iPad or MacBook Pro, both of which are also running iOS5. The MBP with OS X Lion (10.7.2) can connect over BT with no issues to the iPad. The MBP will sense the iPhone 4S, but when attempting to pair the 4S displays the the error message that the MBP is not a supported BT device. This was attempted with two separate iPhone 4S devices so unlikely that it is faulty hardware.

BT is not a primary concern for tethering to the iPad or MBP because WiFi can be used for that purpose. The major compatibility concern is with automobile BT systems, many of which are using BT 2.0 code. Someone apparently forgot to properly regression test the code for backward compatibility!

Not sure I'm doing this right, I'm new to the forum. After upgrading my iphone 4 to OS5 I cannot get my oticon blue tooth interface to work. It is listed as a source and when I first dial it shows the streamer as active but as soon as the phone rings it switches to the iphone audio. The oticon is an interface to my hearing aids and I really need it. I tried to restore back to the old OS but it just keeps putting me back on OS5. This worked before I upgraded.

Sorry John, I'm just going to add to the confusion.

I have a 3GS and a Clarion FZ709 car stereo. For two years it has been a wonderfull marriage between the two. My phone never left my belt but it would switch to play my music as soon as I started the truck and calls came and went simply fron voice commands. And then came IOS 5. Now, no calls through the radio and none of my music. The phone will connect just for a few seconds then say "Not Connected" even though the radio can tell me what percentage of power is left in the phone, free space and the like. Here in Manitoba using a cell phone whilst driving is illegal and very expensive if caught. I can wait for a fix IF I know there is one iminent so "balls-up" Apple and send out a status report on the RSS feed!

I'm having issues also. I can no longer successfully pair my MBA or iPad 2 with my iPhone 4 after updating to iOS 5. I've tried a restore but problem still exists. Hopefully Apple will provide an update soon.

I just tried to connect an iPhone 3GS with iOS 5.0 and it will not pair with MacBook Pro, iPad, etc. It is certainly starting to look like the 5.0 software.

Same issue here.

My iphone 3S with IOS 5 will no longer remained paired to my 2011 Audi S4. I can pair it, but it is lost with each new startup of my car.

Same issue here.

I see no contact data and telephone number to my BMW E61 (2007).

It worked fine before the update.

iOS5 bluetooth profiles adhere to the latest 4.0 specifications, so after you upgraded from iOS4 you have to upgrade software on all other bluetooth enabled equipment to be compatible with Apple industry leading innovations :-)

Other solutions: don't upgrade / wait until Apple fix the problem / use other phones in cars?!

The reason I believe it is a bug is that my iPhone wont successfully sync with my iPad 2 or Macbook Air (2011). All my devices run on Apple's latest OS updates (iOS 5 & Lion 10.7.2).

Me too - in the same boat as everyone else, bt paired perfectly well with my ford fiesta zetec until the upgrade - can you un-upgrade? I want to go back to the previous version!

Yes, I did find that my Oticon Streamer works after upgrading it. Had to take it to the audiologists to have the firmware upgraded. All is well now (except a little static sometimes)
