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

Try following these steps first

To get help with pairing a Bluetooth accessory, such as a wireless keyboard, to your iOS or iPadOS device:

1. Make sure your Bluetooth accessory and iOS or iPadOS device are close to each other.
2. Turn your Bluetooth accessory off and back on again.
3. Make sure your Bluetooth accessory is turned on and fully charged or connected to a power source. If your accessory uses batteries, see if they need to be replaced.
4. If there's an app that you use with the Bluetooth accessory, go to Settings > Privacy & Security > Bluetooth on your iOS or iPadOS device, and make sure you've turned on Bluetooth for the app.

It depends on what the issue is.
