Why do I need to select the bit rate again on inquiry or selection state?

Latest Updated:03/21/2012

Question:

Bit rate settings are automated on the "bit rate adjustment state" in boot mode. Why do I need to select the bit rate again on the "inquiry or selection state"?

Answer:

The bit rate adjustment is usually connected at a low baud rate, which takes time for writing. Resetting to a high-speed baud rate will shorten the writing (communication) time.
The command to speed up the baud rate is the "new bit rate selection (H'3F)" command.
