We don't know what type of information you are talking about.
The solution may be iCloud, which would allow these devices to share contacts, calendars, notes, etc.
Or the solution may be AirDrop, if your iPhone and iPad are new enough.
This may help as well:

Perhaps you're confused because you tried to use the onboard Bluetooth to transfer files between your devices and failed? That's because you can't use Bluetooth with any iDevice to "pass information back-and-forth" because it's not a feature of iOS and never has been.
Bluetooth support for iDevices is listed in this Apple Support Article:
HID Profiles allow connectivity to Bluetooth keyboards, mice, speakers etc. sberman's response answers your question as best as anyone else can.
