# JY-MCU Bluetooth board ----------------------------------------
|
|
|
|
# This opens connection with Bluetooth module connected to Y1, Y2 (UART 6)
|
|
# Then it sets the repl output to this UART.
|
|
#COMMANDS AT - does nothing but get an ok.
|
|
# The posible baudrates are:
|
|
# AT+BAUD1-------1200
|
|
# AT+BAUD2-------2400
|
|
# AT+BAUD3-------4800
|
|
# AT+BAUD4-------9600 - Default for hc-06
|
|
# AT+BAUD5------19200
|
|
# AT+BAUD6------38400
|
|
# AT+BAUD7------57600 - Johnny-five speed
|
|
# AT+BAUD8-----115200
|
|
# AT+BAUD9-----230400
|
|
# AT+BAUDA-----460800
|
|
# AT+BAUDB-----921600
|
|
# AT+BAUDC----1382400
|
|
# AT+VERSION
|
|
# AT+NAMEnewname This is the name that will show up in windows.
|
|
# AT+PIN???? set 4 digit pairing pin.
