PC can’t support the baud rate lager than 115200. The solution is: make the MCU have higher baud
rate (lager than 115200) through programming, and reset the baud rate to low level through the AT
command.
The baud rate reset by the AT command can be kept for the next time even though the power is cut
off.
3. Reset the Bluetooth name
