Hello everyone,

I am developing an application that aims at pairing a WP8 phone (Lumia 920 in my case) with an Arduino. The Arduino has an NFC antenna + Bluetooth Shield.

The idea would be to tap the phone to the NFC antenna, launch the app automatically, and automatically pair phone&device in Bluetooth.

I have been through a lot of resources, but the only way I have found to create an app-to-device Bluetooth connection in Windows Phone is the following : using the PeerFinder class with the PeerFinder.AlternateIdentities["Bluetooth:Paired"]. But this works only with devices that are already paired manually in the control panel.

The thing is, I am sure that there is a way to pair devices automatically. Indeed, the Nokia Play 360 does it. So, is it only limited to certified partners, or can anyone implement such a thing? And if yes, how is it done?

Note : I have read about the NFC Forum Handover protocol, which is apparently possible in Windows 8. Is there something similar in Windows Phone 8?

Thank you very much for any idea!

Marius
