If you are having trouble connecting a new bluetooth device or staying connected to a device that was previously connected, it may mean that the bluetooth cache on your device is disabled.
Fortunately, the bluetooth cache is easy to clear, usually this solves common connection problems, here are the steps.
Clear Bluetooth cache on iPhone or iPad:
1. Open the Settings application and click "Bluetooth".
2. If you are experiencing an issue with a specific device that has already been paired, search for it in the "My devices" menu and click on the "i" icon next to it, then choose the "forget this device" command.
3. If your problem with Bluetooth is more general - for example: you cannot pair any new device with it - delete all devices with the "forget all device in my bluetooth list" command (you will need to re-pair it once Other later).
4. Restart your device.
After restarting the iPhone or iPad, the bluetooth cache will be cleared, and you can pair your devices to use them again.
Clear the bluetooth cache on Android phone or tablet:
1. Go to the settings feature in the device.
2. Click on "Connections", then click "Bluetooth".
