● We also provide the Arduino example source code to guide developer to program with the Feasycom Bluetooth module.
1 Why the Serial Monitor app print “Cannot get correct baudrate”?
A: Please check whether the hardware connection between Arduino development board and FSC-DB008 is correct. When FSC-DB008 is working normally, the blue indicator light will flash. When Serial Monitor app prints “mySerialbaudrate = 38400”, it means the connection is successful.
2 Why the program upload failed?
A: Please check whether the other software has occupied your serial port. If occupied, please close that software.
3 Why can’t I get the response when I send AT-Command ?
A: Please check whether the AT command you sent is correct, . Illegal command will never be responded to. All AT commands should be ended up with New Line and Carriage Return, so select Both NL & CR at the bottom right of the Serial Monitor.
