I understand you have issues connecting your device to the sprocket printer.
 
Don’t worry I’ll try to help you out.
 
Did you make any changes to your printer?
 
Try the steps recommended below.
 
First, unpair and delete the sprocket app from your smartphone and install the sprocket and app and pair the sprocket again to your smartphone.
 
Please share the operating system you are running on your smartphone or PC to assist you better.
 
Try few steps recommended below.
 
1.    Reset the Sprocket unit by placing a push-pin or needle into the small hole on the rear of the unit.  (Reset instructions in the support doc HERE)
2.    Plug in the Sprocket unit with the provided micro-USB cable.  Connect to either a computer USB port or USB wall charger.
3.    Allow the Sprocket unit to charge for 10 minutes.  Note:  A call back may be required in these instances.
4.    Power on the Sprocket unit by pressing/holding the power button for 3 seconds.
5.    A white LED should illuminate on the rear of the unit if power up is successful.
6.    Remind the customer to charge their Sprocket for an additional 60-90 minutes to enable a full battery charge.
 
 
If the issue still persists uninstall the sprocket app and reinstall the app and try updating the sprocket firmware from the sprocket app and check if it helps.
 
Open Sprocket app go to menu—>Sprocket—→ Printers; A blue firmware update link will be present if an update is available.
 
Also, unpair the sprocket from your smartphone and add the printer again and check if it helps.
