Hello,
If you could drive both of Bluetooth module with signal dongle, I think now you just need to make a simple protocol to control two robots.
exp:
!AF -> robot A move forward
!BF -> robot B move forward
note:
! -> header byte
A -> address byte
F -> command byte
Like the commands above , when the two robot receive all the commands from the dongle, they could figure out whether the command is valid according to the byte after the header byte.

Thanks Lauren. Actually this is exactly one of options I was thinking of. But the problem appears to be simpler. When single dongle connects to multiple Bluetooth modules, Windows (in my case) creates one virtual COM-port (really 2, in and out) per Bluetooth module. You can just work with ports, no broadcast. - You Reply: Current results. Use single dongle for all [DFRobot Bluetooth] chips. The same paring code for many devices seems to be ok.
