@Chalbrown87
Welcome to HP Forums, 
This is a great place to get support, find answers and tips. Thank you for posting your query. I’ll be more than glad to help you out 🙂 
 
To diagnose this issue, check if other devices connect to your phone Bluetooth.
Uninstall and reinstall the Sprocket app and try connecting again.
If issue persists, reset your mobile device and Sprocket:

Turn off your mobile device, and then turn it back on.
Turn on the Sprocket.
Locate the Reset button.

HP Sprocket 200 Printer: Remove the paper cover, and then use a narrow object, such as a pen or paperclip, to press and hold the Reset button for 3 seconds. The Sprocket resets and turns off.
 
 
 Turn on the Sprocket and try to connect to Bluetooth again:

 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.
 Be sure Bluetooth is turned on for your mobile device or tablet, and then open the sprocket app. Select the Main Menu in the upper left-hand corner.
 Tap sprocket to pair your printer with your mobile device or tablet. A pop up message will direct you to Android™ Settings to pair your printer. A list of available devices will display.
 Select your printer from the list to pair your devices.

If you have already tried those steps and issue persists, I suggest calling our phone support regarding warranty and service options.
