FAQ

• Why does the Serial Monitor app print "Cannot get correct baudrate"?
  A: Please check whether the hardware connection between the Arduino development board and FSC-DB200 is correct. When FSC-DB200 is working normally, the blue indicator light will flash. When the Serial Monitor app prints "mySerialbaudrate = 38400", it means the connection is successful.
• Why does the program upload fail?
  A: Please check whether another software has occupied your serial port. If it is occupied, please close that software.
• Why can't I get a response when I send an AT-Command?
  A: Please check whether the AT command you sent is correct. Illegal commands will never be responded to. All AT commands should be ended with a New Line and Carriage Return, so select "Both NL & CR" at the bottom right of the Serial Monitor.
