Problem pairing headset after upgrade to IOS 7 ?
I have a Plantronics Voyager Pro and was having similar issues after upgrading to IOS7.
This is what I did... See if it helps you...
1. I went to Settings in iPhone and turned "off" bluetooth option
2. Then I turned off my bluetooth headset
3. I went to Settings again in iPhone and turn "on" the bluetooth option so that it goes to searching mode
4. Turned on my headset.
5. Viola! It showed my Voyager Pro, but when I clicked on it to connect, it failed.
6. I tapped on the '(i)' next to my bluetooth device within the bluetooth setting on iPhone and did a 'Forget this Device'. I also turned off my Voyager at this point.
7. Then I turned on the headset until I saw the blue light; and continued to hold down the on/off (power) switch until the blue/red light started flashing. (hard reset)
8. My iPhone again discovered my Voyager and I tapped on it to connect.
9. Yippe! all set... 🙂
Basically, holding down the power button on the headset did a hard reset, and starts a search for a new device or new software, in this case it was iOS7. Otherwise the poor headset was searching for its old buddy (iPhone with IOS6).
Cheers!
