QR code bluetooth pairing

I am looking for a text based recipe to allow a QR code generator to generate a QR code that can be scanned by the phones camera and open the settings to pair to a bluetooth device. This recipe already works for the pairing of the phone with a WiFi connection and has been described on Wikipedia: https://en.wikipedia.org/wiki/QR_code scrolling down to Join WiFi network and looks like this:

• Common format: WIFI:S:<SSID>;T:<WEP|WPA|blank>;P:<PASSWORD>;H:<true|false|blank>;
• Sample WIFI:S:MySSID;T:WPA;P:MyPassW0rd;;

I am looking for a recipe like this to pair the iphone with a bluetooth device?
