Capacitive Fingerprint Communication Failed Error
![userHead](https://dfimg.dfrobot.com/dfPortrait2.png)
I have this Capacitive Fingerprint Scanner/Sensor Arduino - DFRobot fingerprint scanner and i cant seem to change the baud rate back, The defualt read was 57600 when i ran the code, it changed to 8389400 and now it has a communication failure error and i can get anything to work on the fingerprint scanner.
What can i do to restore this to work.
Pls modify the code. The module initialization baud rate needs to correspond to the baud rate in the code.
FPSerial.begin(57600);

Could you attach the screenshot of the code and the screenshot of your serial monitor?
I found the "communication failed" occured only when you not wired properly or power it under wrong voltage.

Is the fingerprint.setBaudrate(fingerprint.e115200bps); function not working?

i ran the code and its now saying communication error
