Use the Bluetooth SPP (Serial Port Protocol), or be somewhat more intelligent and just use ad-hoc wifi, since you're apparently running on a system that can run linux.

rfcomm is the SPP, yes.  If you've got embedded linux running, you can probably afford to put in a USB wifi dongle.  Then your life is much easier - the protocols are all defined already, and you don't have to worry about low-level communications. 

If you must use bluetooth, be aware that it's not the easiest thing to configure - your best bet is to open an rfcomm tunnel between the two bots and pretend it's a serial port.

Bluetooth essentials for programmers By Albert S. Huang, Larry Rudolph

Bluetooth to bluetooth rfcomm can be done by switching one of the modules to master mode, and creating a connection between the two.  Then, treat the resulting /dev/rfcomm* port as a serial port, which is much easier to deal with.  The book you list seems to be good, but I don't have any personal experience with it and thus cannot make a recommendation.
