I found it   I still don't know how to do it programmatically but at
least now I know that it is possible to unpair by going to
Settings>Wireless & Networks > Bluetooth Settings and long press on
the appropriate device in the list of paired devices.  And by
unpairing the device that I could not connect to before, I now can.  I
still don't understand what caused the problem I had (inability to
connect to one of two identical devices) but it was fixed by
unpairing.
