R551 Did not find fingerprint sensor :(

Did you run the set_parameters example? If you did, it may have changed your baud rate to 9600. So change your SoftSerial baud rate in the enroll example and try again

I tried changing the baud rate also but I am getting the same message "Did not find fingerprint sensor". I have one more sensor it is working good on the same piece of code does this mean my sensor is broke or is having some problems and it will not work if yes can you suggest me how to fix it @brianrho
Thank You!

The problem is solved actually I had uploaded the change password code which changed the password to "0x12345678", now I have changed the password again to "0" and the sensor is working fine
Thank You! for your help @brianrho

Ah, glad to hear it worked out, will have to add a warning to the sketch.
