Bluetooth Not Working After iOS or mac OS Update?

Many of our readers report Bluetooth not working with headphones, car audio, and other Bluetooth enabled audio devices following upgrades to iOS and Mac OS.  Even some users with Bluetooth hearing aids report they no longer work!  And symptoms include crackling, static, dropouts, skipping, and popping.  Not good at all, especially for the hearing impaired.

iFolks using Bluetooth in their cars experience frequent audio disconnections, occasional choppiness, a lot of static, and even phone calls getting stuck when trying to end calls. As a result, these Bluetooth problems make listening to your favorite tunes or calling a loved one a most un-fun experience. And for iFolks using Bluetooth hearing aids, this is a major quality of life challenge.

Bluetooth Not Working Tip

Until then, there is a workaround that appears to work for most iFolks.  Turning off LTE when using Bluetooth headphones and other audio devices solves the problems for now. And many of our readers report that this temporary fix performs reliably.  Please note that turning off LTE reduces your data speed to 4G, 3G, and even 2G or EDGE when not connected to WiFi.  And remember that LTE is dramatically faster than 3G, 4G, 2G, or EDGE.  So a noticeable change in speed is part of this workaround.

Other readers suggest using personal hotspot.  Go to Settings>Personal Hotspot, replace the WiFi password from its default, switch on Hotspot, and finally switch WiFi OFF.  Now try pairing your Bluetooth device(s) again.

If you don’t find Personal Hotspot, there are two places to look. Check Settings > Personal Hotspot.  If not there, then check Settings > Cellular > Personal Hotspot. If you can’t find or turn on Personal Hotspot, verify that your wireless carrier supports Personal Hotspots, enabled it and that your wireless plan supports it.

For iFolks using Bluetooth in their automobiles, the LTE tip helps.  Other fixes include cycling your Bluetooth radio to get it to work again. And sometimes restarting entirely fixes the problem.
