My iphone 4 cannot find bluetooth headset after ios 5 upgrade

My iPhone 4 and my Plantronics Voyager pro plus headset were working fine untill I upgraded my iPhone OS to 5.0

I tries turning both devices on and off but no luck. The headset doesnt even show up in the bluetooth devices list. I tried pairing my headset with my buddy's android phone and it works fine, infact it worked fine with my iPhone 4 and OS 4.x and I have been using it since last 6 months.

Any solution for this issue?

iPhone 4, iOS 5

I'm having a similar issue with my plantronics blue tooth. Not sure if the model # is Discover 925 or a different # (looks like it), but I make sure it's on and ready to be discovered, blue tooth is set to on in settings/general, devices is searching (now discoverable), and nothing else happens. I have been unable to get the iphone 4s to recognize the device, let alone get the 2 to pair, so I can use the plantronics blue tooth. Had no problem pairing with Motorola Droid (1st edition)

Ok, for those of you who have a Plantronics Voyager Pro bluetooth headset, I got a connection/"pairing". This is what I did:


1) I turned off my bluetooth headset.

2) Go to Settings in iPhone and turn "on" your bluetooth so that it is searching ...

3) Then I turned on the headset until I saw the blue light, AND CONTINUED to HOLD DOWN the on/off switch until the blue light was FLASHING.

4) The "pairing" took place during the flashing.


Holding down the power button on your Voyager Pro headeset acts like as a "hard reset", and starts a "new" search for a new device or new software, in this case it's iOS5 or your new iPhone, or both.


Before doing the steps above my iMac (desktop computer) had the same problem of not "discovering" my bluetooth headset. But after I did the steps, I set my iMac to "discover mode" and the "pairing" between these two devices was successful.


OTHER bluetooth headsets

Try doing a "hard reset" on your bluetooth device, if you are trying to connect with an iPhone, iPad, or desktop computer that is running iOS5 or Lion.


The problem seemed that my bluetooth headset was trying to connect with devices that were paired with previous operating systems (ie: iOS4 or Snow Leopard). When I upgraded my operating systems to iOS5 and Lion, my bluetooth needed to "start fresh", hence the "hard reset" on the bluetooth.

Hi josefromdc,

Assuming your pairing was successful according to your post (the iPhone recognized your bluetooth and you selected your bluetooth in the iPhone bluetooth settings under "devices"), you shouldn't have to repeat the steps. Make sure you select your bluetooth model listing once it shows up under "devices". After you select your device, when your bluetooth is on and in range of your iPhone, the pairing is automatic.
