How do I get my iPhone XR Bluetooth to work again?

Hi abcatmom,

welcome to the Apple (user-to-user) Community.

Re: iPhone XR Bluetooth

You might want to try restarting your iPhone, as that sometimes puts things back in order: How to: Restart your iPhone

The bluetooth accessories would need to be charged, and in "discovery" mode for iPhone to connect with them. (Some accessories may need an app / firmware / update/ from the manufacturer). You may also want to "reset" an accessory.

See if following Apple's methods in the articles below can help:

Set up and use Bluetooth accessories on iPhone - Apple Support

For non-Apple accessories:

Pair a third-party Bluetooth accessory with your iPhone or iPad - Apple Support

or

If an app would like to use Bluetooth on your device

Trouble-shooting:

If you can't connect a Bluetooth accessory to your iPhone or iPad - Apple Support

All the best :-)
