@debdunatov
Thank you for posting on HP Forums, 
Riddle_Decipher is at your service. 
 
As I understand you need help connecting your iPhone 6+ to your HP Sprocket,
No worries, as I’ll be glad to help you, that said, I’ll need a few more details to dissect your concern & provide an accurate solution: 
Did you check the user guide for details?
(Click here to view your user guide, look under page 4)
 
While you respond to that, here’s what you need to do:
 
1. Press and hold the Power Button for 3 seconds to turn on the printer. The LED will flash white as the printer
powers on and remain solid white once fully powered on.
2. Open iPhone® Settings and select Bluetooth. Turn Bluetooth on and then select the printer from the listed
devices.
3. Next, launch the sprocket app. See “Installing Mobile App” for more information.
 
• A reminder message will appear if you try to print a photo and are not paired with your HP printer.
• If your mobile device and printer will not pair, try reseting the printer. For instructions, see FAQ “How do I reset my printer?”
• Only one iOS device can pair with the printer at a time. To share the printer, turn off Bluetooth and allow someone else to pair.

And Have a great day Ahead!
