New iPhone 15 Bluetooth not detecting nor pairing with other devices

[NG4291]

Hey folks, I was able to migrate my "working perfectly well” iPhone 12 to the new iPhone 15 earlier this week. Since then, seemingly, the Bluetooth hasn’t been able to detect nor connect/pair to any of my existing devices including the Bluetooth speaker, printer and even to the one in my vehicle despite switching the on/off and on the Bluetooth settings.
Any idea how to fix that? Please advise, thanks in advance!

Good Day.

Bluetooth pairing problems can be frustrating, especially when you're trying to connect your iPhone 15 to a new device.

There are a few things you can try to fix the problem, including restarting your devices, making sure Bluetooth is enabled on both devices, moving closer to the Bluetooth device, forgetting the Bluetooth device on your iPhone and then pairing with it again, resetting your iPhone's network settings, and updating your iPhone to the latest version of iOS.

1. Restart the iPhone & Bluetooth Device. This a simple but often effective solution for many Bluetooth problems. Restarting your devices can clear any temporary glitches that may be preventing them from pairing.
2. Make sure that Bluetooth is enabled on both devices. On your iPhone, go to Settings > Bluetooth and make sure that the toggle next to Bluetooth is turned on. On the Bluetooth device, consult the user manual for instructions on how to enable Bluetooth. 
3. Move closer to the Bluetooth device. Bluetooth has a limited range, so try moving closer to the device you're trying to pair with. This can help to improve the signal strength and make it easier for the devices to find each other.
4. Forget the Bluetooth device on your iPhone and then pair with it again. To do this, go to Settings > Bluetooth and tap the i icon next to the Bluetooth device you're having trouble with. Then, tap Forget This Device. Once the device is forgotten, try pairing with it again.
5. Reset your iPhone's network settings. This will reset all of your Wi-Fi and Bluetooth settings to factory defaults. To do this, go to Settings > General > Reset > Reset Network Settings.
6. Update your iPhone to the latest version of iOS. Apple often releases software updates to fix bugs and improve performance. It's possible that a recent update could fix the Bluetooth pairing problem you're experiencing.

If you've tried all of the above tips and you're still having trouble pairing your iPhone 15 with a Bluetooth device, you may need to contact Apple Support for further assistance.

Here are some additional tips that may help:

• Make sure that the Bluetooth device is in pairing mode. This process varies depending on the device, so consult the user manual for instructions.
• Try pairing your iPhone with a different Bluetooth device to see if the problem is with your iPhone or the Bluetooth device.
• If you're trying to pair your iPhone with a car stereo, make sure that the stereo is in pairing mode and that the volume is turned up.
• If you're trying to pair your iPhone with a Bluetooth speaker, make sure that the speaker is charged and that the volume is turned up.
• If you're still having trouble pairing your iPhone 15 with a Bluetooth device, please contact Apple Support for further assistance. Official Apple Support
