70 -After using the serial port to connect to the Bluetooth host, send **AT+BAUD7; AT+TIMEINQ40; AT+RESET** three commands and then disconnect the serial port connecting to the Bluetooth host.
70 +The default baudrate of the general Bluetooth host is 9600, we can use the three commands: **AT+BAUD7; AT+TIMEINQ40; AT+RESET** to change the baudrate of the Bluetooth host to 115200, in order to support the use of Dragino Sensor Management Tool V1.4 to download the firmware faster.
