RC figured out quickest way is to leave SumUp box off and let the phone app wake it up to process payment.If it doesn't talk to phone app, long press power button on box for up to 15 sec until you see message like 'Bluetooth resettting' or something. Then box will talk to phone.
i remember why i stopped using the old sum up.it connected to the phone via bluetooth.i always had my phone bluetoothed to the sound system and there would always be a clash when i wanted to use the sum up.
Or just get a cabapp reader if you don't mind paying a miniscule bit more than sum up in commission.
yeah, ive used it to take out money, just like a normal card.
