Mblock - board communication speed


#1

Does anyone know the serial communication speed between mblock and the board?
Just to give an example, the similar [S4A][1] scratch-arduino communication implementation sends sensor state and receives commands from the PC every 75ms (13 times per second).
Knowing this speed is helpful to cope with the limitations of interactive robot control (expecially when movement reacts to sensors).
I wonder if it is set to a standard speed or if it tries to max out the communication speed which therefore could depend on the execution speed of the single commands.
Thanks.
