You didn't post what the 'failure' was but for RFCOMM you can only have
one connection on a server channel (each RFCOMM channel corresponds to
an emulated serial port).

since a TCP connection is defined by the address and port at each end, the
Bluetooth equivalent is more likely to be a a L2CAP connection to a given
PSM which can support up to ~64k channels (though as the Peter Wippich
notes, the number of devices the radio can maintain connections with is
limited)
