I have this sensor : https://wiki.dfrobot.com/Capacitive_Fingerprint_Sensor_SKU_SEN0348#target_14

 

I did by mystake set the fingerprint buildrate in arduino nano:    fingerprint.setBaudrate(fingerprint.e9600bps);

 

And now it doesn't work !

comunication failed and fingerprint lights doesn't work 

Please help !

I have this same problem , after trying to update the baud rate it says communication error and the check baud rate is 8389400 how do you fix this, it keeps saying communication failed error

This code is given in the wiki to query the module baud rate. This sensor only has five baud rate options. It is recommended that you use this code to query the baud rate first.

 

When you use other codes, remember to modify the baud rate in the code. 

e.g.  FPSerial.begin(57600);

 

The module initialization baud rate needs to correspond to the baud rate in the code.
