Sync what exactly? You can put the same content on each device, but you cannot pair them via Bluetooth. Please explain what you are trying to sync.
If they are logged in to the same Apple ID, on each device go to Settings/[your name]/iCloud and turn on the switches for the items you want to sync, then leave both devices plugged in and connected to Wi-Fi until the sync appears to have completed.
What do you exactly mean by synching your iPad and iPhone?
