Most likely causes: Changes on your network or an issue on the router.
Quick Fixes:
Check the iPad and Eftpos are on same network. Look in iPad settings > Wi-Fi
Close and restart the Bustle app.
Reboot both iPad and Eftpos terminal (remove terminal battery if possible and replace)
Does your 8 digit pairing code on Eftpos terminal and Bustle Eftpos settings match? (contact Smartpay if unable to locate)
Have you swapped to a new Terminal? You may need to do a full Delete and Reinstall of Bustle to refresh the settings and allow you to set up again.
Is the Eftpos button no longer there?
Is the Eftpos transaction successful but Bustle doesn't close it off?

Most eftpos issues that occur between Bustle and the Smartpay device are caused by underlying issues on the Network or Router. Rebooting the router may help in the short term but if intermittent connection issues persist, check out the following article:
Further troubleshooting:
Try restarting your router. Turn off the router for a full minute then restart it. Leave it for another couple of minutes. Please note: If you have Star printers, the IP address may have changed so you may need to Search for printers again to locate them - in the Bustle printer settings.
Have there been any recent changes on your network? You may need to contact your IT provider to assist.
If none of the steps above work, it may pay to contact your Eftpos provider:
