As far as i understand the EZ-B system correctly, the bluetooth adapter is acting as a bluetooth->RS-232 bridge, right ? I am currently thinking of replacing the bluetooth interface with a different interface and programming my own control software. Therefore i am very interested in getting the low-level RS-232 protocol to get a direct HW access to EZ-B, independent of the higher level SDK. How is the communication on the RS-232 layer established ? What are the commands to control the movement (servos) ? What is the baudrate and protocol ?

Any information (even if it is source code) would be very helpful :)
