- Turn off Bluetooth on your phone or tablet.
- Close the SumUp App on your device.
- Make sure your card reader is not charging.
- Turn off your reader.
- Now press and hold down the power button of your card reader until you see "Release for BT" on the display.
- Release the power button once you hear a beep.
Now the Bluetooth chip in your card reader is reset. Please wait for a second beep before reconnecting the reader to your phone.
Step 2: Reconnect the card reader
Reconnect the SumUp Air to accept card payments again:
- Enable the Bluetooth on your phone or tablet.
- In the SumUp App, tap on the settings symbol, go to “Payment Methods” and tap on “SumUp Air”.
- Make sure that the last 3 digits that are shown on your screen match the last 3 digits of your card reader’s serial number.
- Confirm the pairing request on your smartphone or tablet by tapping “Connect”. You might need to confirm the connection by tapping the green tick on your card reader.
If you’re still experiencing connectivity issues, please restart your smartphone or tablet. Once you log in to the SumUp App again, try to take a card payment to see if your card reader connects to your device.
