edited to add . . .
we have just tried again and it looks as if we need to connect the Bluetooth before transfers can happen.
My IPad first said it was not paired so I clicked on its name.
now it seems to be trying to connect but keeps saying it is not connected.
do I need to do something else to get it connected
