There is no such restriction in hardware or bluetooth software stack.
Multiple clients can be simultaneously connected to the same RFCOMM channel
on a server.  Use hcidump -X -V to find out where the connection fails.
Make sure that the server is always the master and that the clients are
always the slaves.  This probably requires a role switch after each connect=
.

This syntax is incorrect.  See the rfcomm documentation.
