bluetooth not connecting to devices

Hey Samuel1549,

Welcome to the Apple Support Communities! I see you're having trouble with the Bluetooth feature on your iPhone, so I wanted to reach out with some things you can try that may help. First of all, since we don't know the device model or anything specific about the accessories you've tried to pair it with, we'll have to keep troubleshooting pretty broad to start, like with this article: If you can't connect a Bluetooth accessory to your iPhone, iPad, or iPod touch - Apple Support

Be sure to update the thread with your results and we'll work from there.

Cheers!

most bluetooth devices needs to be put into pairing / discovery mode to pair with a device they have not been paied with before
