Step 2. Check at your computer if the serial port has risen:
Window s: check the device manager, there should be new serial deviced named COMx w hich x is an increasing number. If you use w indow s XP/7/8,
maybe you need install w indow s CDC drivers.
Linux: ls /dev/ttyACM* , you should get /dev/ttyACMx w here x w ill vary depending on w hich USB port you used.
Mac: ls /dev/cu.usb* , you should get /dev/cu.usbmodem14xx w here xx w ill vary depending on w hich USB port you used.
Step 3. Use your favorite serial debugging tool to connect the serial port, the serial has: 115200 baud rate, 8Bits, Parity None, Stop Bits 1, Flow Control None.
For examples:
Window s: use PUTTY, select Serial protocol, fill in the correct COM port of ReSpeaker Core V2, 115200 baud, 8Bits, Parity None, Stop Bits 1, Flow
Control None.
Linux: Depend on your USB To TTL Adapter, it could be screen /dev/ttyACM0(,1, and so on) 115200 or screen /dev/ttyUSB0(,1, and so on) 115200
Mac: Depend on your USB To TTL Adapter, it could be screen /dev/cu.usbserial1412(,1422, and so on) 115200 or screen /dev/cu.usbmodem1412(,1422, and
so on) 115200
Step 4. The default user name is respeaker , and passw ord is respeaker too.
B. Connection via The UART port
In this section w e w ill guide you how to establish a connection from your computer to your ReSpeaker using your USB to TTL adapter w hich w ill be connected to
the ReSpeaker's Uart port (Uart port located just to the left of the ReSpeaker speaker plug).
Step 1. Connect Uart port and your PC/Mac w ith an USB To TTL Adapter. Note that the voltage of RX/TX are 3.3V. If you don't have an USB To TTL Adapter,
you can click here to get one.
Step 2. Use the follow ing Serial debugging tools w ith 115200 baud:
Window s: use PUTTY, select Serial protocol, fill in the correct COM port of ReSpeaker Core V2, 115200 baud, 8Bits, Parity None, Stop Bits 1, Flow
Control None.
Linux: Depend on your USB To TTL Adapter, it could be screen /dev/ttyACM0(,1, and so on) 115200 or screen /dev/ttyUSB0(,1, and so on) 115200 .
Mac: Depend on your USB To TTL Adapter, it could be screen /dev/cu.usbserial1412(,1422, and so on) 115200 or screen /dev/cu.usbmodem1412(,1422, and
so on) 115200 .
Step 3. The login user name is respeaker, and passw ord is respeaker too.
Step 4. If you do not have a USB to TTL Adapter, you may also use an Arduino. If using an Arduino, connect one end of a jumper w ire to the RESET pin on the
Arduino and the other end to the GND pin on the Arduino. This w ill bypass your Arduino's ATMEGA MCU and turn your Arduino into a USB to TTL adapter, see
video tutorial here. Now connect the GND pin on the Arduino to the GND pin on the Uart port of the Respeaker. Connect the Rx pin on the Arduino to the Rx pin
