I am using the Miura reader with severalphones. According to my phone there is a Bluetooth connection to the reader, but the reader does not work. What do I do?

If you are using a Miura readerwith several phones, it is possible that the Bluetooth connection to one phone has already been cancelled, although the reader is still listed under connected Bluetooth devices.

In this case, remove the Miura reader from the list of connected Bluetooth devices on the phone and pair it again as described here.
